INT'IRODU('TIOX

Plans for a natural history survey of the Island of Porto Rico were
drawn up in 1913 by the New York Academy of Sciences, with the active
cooperation of the 'Insular Government of Porto fico, The American
Museum of Natural History, the New York Botanical Garden, and Co-
lunbia University. The plans covered work in all the different depart-
ments of Zoilogy, Botany and Geology. The first field work was begun
in 1914 and the author was given the assignment to report upon the
mammals of Porto Rico.
At the time this survey was planned, the known mammal] life of Porto
Rico was exclusively a bat fauna, no terrestrial land manuals other than
introduced species being known from the island. The investigations of
the anthropologists under Dr. Franz Boas, in 191., gave promise of most
interesting and unexpected additions to the list of mammals. In exca-
vating shell-heaps, and caves formerly occupied by the aborigines, they
discovered fossil remains of three described rodents and a new ground-
sloth. This evidence of a fossil namnmal fauna greatly stimulated inter-
est in what had promised to be a rather narrow field of research. Active
field work for mammals was begun in May, 1916, and the author wa'
able to further increase the list of terrestrial mammals and secured a
Ireat abundance of fossil material, as well as fairly extensive collections
of the bat fauna.
The author was accompanied throughout the field work in Porto Rico
by his wife, the late Edith I. Anthony, who was an active assistant dur-
ing this time and found many of the specimens brought back by the
expedition.

details of field work. Our first move took us to San German, near the
west coast of the island, where we met Dr. Spinden. of the American
Museum Department of Anthropology. Cooperative investigations were
carried on for several days with the expectation of finding mammal re-
mains in Indian shell-heaps and kitchen-middens. Although search was
extended as far as C'abo Rojo, this immediate region did not yield very
promising results and it was necessary to move on to Adjuntas. Both at
San German and Adjuntas no opportunity was overlooked to collect
specimens of the living manm als, namely, the bats. The third site
,-elected was Utuadu, in the interior of the island, and from this region
we secured some of our must. important material. Owing to the terrible
conditionn of the trail< and to a lack of understanding on the part of the
natives, great difficulty was experienced at first in locating caves and
favorable spots for excavation. Eventually an abundance of fossil main-
mal material wa.- sen'red from caves which were worked from Utuado as
a base. Several side trips were made while we were located at Utuado,
line of these being to tlie Hacienda Jobo and another to Quebradillas.
Dr. Spinden. finishing his arelhaological investigations while we were at
Utuado, returned to San Juan and to New York.
Upon completing the region about Utuado. it was necessary to return
for a stay of several days at San Juan. and during this time, July 3 to
.July 8, several important caves in the San Juan vicinity were worked.
One of these caves is the type locality for two species of bats. It is of
interest to note that bats were more abundant and representatives of
more species were collected about the San Juan sector than anywhere
else on the island. Leaving San Juan, we returned to Utuado to pick
up fossils which had been excavated on contract, and passed on west to
Lares. Not very much was added by the visit to Lares. which seemed to
be a region of rather limited possibilities, although there is an interesting
deposit of fossil-bearing Tertiary limestone near San Sebastian. A
delay in the receipt of funds expected from San Juan made necessary a
return again to that site, and, as before, while waiting there, more of the
caves of the region were visited.
We then motored to Manati, and a very promising field for fossil mam-
imals was located near Morovis. It was possible to work out from Manati
as a base. and several oaves near Morovis. yielded a great abundance of
nmamnial remains. On July 21 we returned to San Juan. and then went
eastward to investigate the high mountainous area about El Yunque.
Our headquarters were established at the Preston ranch, near Naguabo,
where we were most hospitably received by the overseer. Unfortunately.
no very extended work could be carried on here because of continuous,
heavy rains. A long, all-day tramp back toward the summit of El

Yunque convinced me of the uselessness of any work in that region dur-
ing the short time at our disposal and the probable negative results as
far as mammals were concerned. From the Preston ranch our route took
us to Coamo by the road which parallels the coast. and from Coanmo we
went inland as far as Cayey. 'The next move brought us to Ponce, where
we left the automobile, took train and went around the coast, stopping
oft at Manati once more'in order to run down several clues which we had
been unable to investigate on the former visit. This completed the field
work, the collecting at Manati being the last. On August 2 we left San
Juan for New York.
So far as was possible in the limited time available for the work, spe-
cial L'.it- were made to investigate each distinct type of country and
each different ecological area. In a general way the entire island was
covered, and although many regions were passed by, it was felt that work
in these places would serve only to duplicate results obtained elsewhere.

PiREV1OCS Wo!:K ON THE MAMMALS OF PORTO TiCO
The first work on the mammals of Porto Rico was done by Dr. Juan
Gundlach, who made three trips to the island from Cha, in 1813. 1875
and 1881. The principal localities worked by GCundlach were Aguadilla,
Guaniea. Lares, Utnado, Arecibo, Q ncbradillas. Vega Baja andI Bayamon.
The results of the first two trips appeared in the .1 oles de la Sociedad
EspaFiola de Ilistoriea Natllal for 18l8. The part devoted to mammals
is not very extensive and occupies only three pages: four species of hats
comprised the known indigenon>s mnamnalia. Other collectors did work
on the island at various times, but the total results ihale not greatly en-
larged the knowledge of Porto Rican mammals, partly through non-
publication. Mr. Alex. Wetmore, of the United States Biological Sur-
vey, worked in Porto Rico from 'December, 1!11, to September, 1!91.
primriily on the birds of the island. but incidentally secured a fine col-
lection of the bats, ?35 specimens, among t ihe a new form of IEplesilrs.
The Museum of Comparative Zoiilogy sent an expedition under Dr. C. M1.
Allen to Porto Iico in the spring of 1917. a small collection of bats and
fossil mammals being secured, none of which proved to 1,e new.

SPECIMENS 1LEC:lVIIED FROMnr PORTO RICO S'RSI.EQU'ENT TO THE NEW
YORn ACADEMY EXPEDITION OF 19 G
Important collections of fossil mammal remains have been'made by
Seilor R. Fernandez acceira, of Rio Piedras, Porto Pico, who apparently
found the bones while 1;.;I'.- in eaves for fertilizer. Senior Macceira has
carefully saved all bones found in this manner and since 1920 has for-









xwarded three lots to the American Museum. The first collection, which
wn the largest, and the third collection were purchased by the Americ-an
Mu-eum andl the second collection was acquired by the Museum of Com-
jparative Zollogy. The lots purchased by the American Museum are ex-
rhilively grould-sloth bones and it will be possible to mount a composite
-keleton of this animal from the material.
Sefior Maccira writes that these ground-sloth bones all eame from the
same cave, at Cabachuelas, Barrio de l-a Torreeillas, near Morovis. The
place ggoes under the local name of Cerro T1 unee. It is a large cave, about
sixty-five meters lonil by forty-eighlt wide The hones were found at a
depth of seven or eight meters.

ACKyOWLED(; M ENTS

It is a pleasure, to acknowledge the wide-spread interest in the torto
l'ican work and the great help and assistance which has been given me
lib ditffrent institutions and individuals. 1r. 11. E. Crampton. of the
Porto Rican committee of the New York Academy of Sciences. has done
everything to make the work suceesful. The ollicials of the In'nilar
xovernmenet, (Governor Ynager, the auditor, Jludie BoPnner. and the CIhief
of the Insulnar Pliee. Colonel Shanton. assured the success of the fiehl
work by their cooperation. The insular police were always eager to ren-
der very capable assistance wherever I found it necessary to call upon
them. To the late Basil Iicks Dutcher. then a Major of the I. S. A.
and surgeon for the insular troops, I owe a debt of gratitude, as dIoes
each one of the Acad,'em field workers in Porto Rico. who found him a
clo,-e friend. The residents of Porto Rico I found always interested and
helpful, and T wish to acknmoleldge especially the cooperation in my work
given hb Mr. Leopoldo Strnhe. of UTtuado. Mr. Gerrit S. Miller, Jr.. of
the United States National Musemn. has been very generous in the
matter of loans ( f West Indian bats and other material.. Mr. Alex.
Wetmore. of the United States Biological Survey, kindly allowed me the
use of his bat records from Porto Rico. Dr. G. MI. Allen, of the Museum
of Comparative Zoology. and Dr. Witmer Stone, of the Philadelphia
Academy of Sciences, have also assisted by the loan otf needed material.
The late Dr. J. A. Allen. Curator of the Department of M ammals in
the American Museum, gave me the great benefit of his long experience
in numerous consultations, both on the systematic work of the report
and on editorial matters.. Dr. W D. atthew, Curator of- Vertebrate
Paleontology of the Amdrican Museum, and M)r. W\alter CGranger, of the
aune department, have assisted me in many ways, not only by contribn-
tion of departmental aid but by con station as well. The Director of'

the Americatn Museum, Dr. F. A. Lucas, showed his sympathy and in-
terest in the enterprise and ldid all that he could to further the work.
Finally, this list would ln1t be complete without an expression of grat-
itude to my wife. tile late Edith I. Anthony, who from the beginning
took an active Ihand in the col election of material and its preparation, the
writing of notes, the copying and arranging of the manuscript, the
figures and the bibliographvy.
'The text figures, with but few exceptions, were made by Mr,. Helen

by means of the camera luciida and then the proportions checked by

lr. .ianesul P. C'hapin, at that time a co-worker in the same department
with me. for the benefit of much advice and help.
All of the typing and work of a secretarial nature has been done by
Mihs Ida Grobe, of the department staff, who has hben exceedingly help-
ful to me in the preparation of this report, and whose name should not
be omitted from this list of acknowledgments.

I have constantly consulted lThe 'Failies and Gerrit S. Miller. .r. (U. S. National 3nseun, Bull. .', 190. ). and
helped myself liberally to the data therein when giving the characteriza-
tions of tile bats, because I know of no more authoritative source than
this invaluable report. In many cases it may be noted that my descrip-
tihns are but slightly altered transcriptions of Miller's wording.

Porto tii-o is a small island, 95 miles in length by ;35i miles in breadth,
with an area of 3,(il!8 square miles. In shape it approximates a paral-
lelogram, the sides of which run in the ri'dinal directions of the conm-
pass. 'ITh island is diiided by physiographic features into several very
distinct ecological areas. mountainn ranges of fair elevation extend ea-t
and west for tie full length of the island, reaching in the western part
an elevation of nearly [000 feet and culminating at tile eastern end in
1h1 Yliinqu'. of 1985 feet elevation. These ranges form the backbone of
the island and the greater part of its area as well. A large part of the
northwestern end of the island is limestone, which occurs ns a layer of
considerable thickness. 'Thet southwestern part of the island atls contain.l
limestone. but it is here widely scattered. Thle eastern end of the island
consists of cong lon rates and inetanmorphie rock.







IX'V [O V 1Il I 1,S of'" PORTOI~ PICO


On parts of the island the annual rainfall is very heavy, notably in the
high moun itains at the eastern end and throughout (lie mIountain district
in general. On the southwestern end the rainfall is very scanty and
desert conditi ins prevail. There are several good-sized rivers, the largest
flowing through \alleys of considerable extent. Throughout most of the
island the virgin forest lhas been destroyed to make way for plantations,
bnt in a few isolated localities remnants of the early forest remain. Such
places may le found about Maricao, Ultuado, and to the greatest extent
in the Luquillo region. Cloe attention was paid to changes in the ecol-
ogy of the country traversed, in the hope of finding changes in tile bat
fauna, but none were noted: although, because of the short time spent in
the arid southwestern region, the most likely field lfor such obser ovation
was not by any means exhausted.

PR'IOBABLE AG;E OF TIll1 FOSSILS

A conservative estimate of the age of the fossil species of Porto Rico
would place them in the Pleistocene and prohibbly late Pleistoiene. In-
deed, it is more than probable that some of this fauna persistedlinto the
Recent. Isoloboito n we 11ve found in the shell-heapl and know that it
was an article of ldit 11aong the Arnawaks. Many' of the bone, of, tlhe
other species haNe every Iaplpearalce of being fairly recent, geologically
Sspaking. Tlhe evilCle would indicate that the fossil species taken were
all eontemlporaneoun -ine they o(rlil in the same formation in nearly
every instance. A possible exception is sv.olboholn n, which was dnubtless
the last manual to becomCe extinct on the island.
The fossil remains were encountered at depths of a few inclhe, from
lth top down to as deep as nine feet. Often but little scraping wa- nec-
,isary to uncover bones. although in this connection it is well to state
liat, the natives of the island are in the habit of digging out the bat
nl.nall frol the wavess anid frequently take the earth from the floor if the
canes as fertilizer. Tiiiis the height of the eaith in any cave may not

posit. Tloweler, the height of the original deposit is generally hetralye

by a discolored ring around the walls of the cave. The bones were verv
fresh in appearance when excavated and had not undergone any miner-
alization. In the case of the bats found fossil in the Cueva Catedral. a
number of skulls were collected that prove indistinguishable from the
living bats, and this formation contained the insectivore Nesop1honles1
as well.
Fossils collected in Cuba and in Jamaica under similar conditions
display unmistakable evidence of recent deposit.
As a general rule, the specimens were found in dry limestone caves in
the mountainous part of the island. Caves on the sides of i-mall hills
yielded the most bones, and the size of the cave was immaterial. The
cave that contained the greatest amount of ground-sloth material was a
small one, with the entrance on a rather steep hillside and opening out
of a sheer front of limestone. Inside, the cave did not open out very
wide, but had a deep fissure at the left toward which the flo:r sloped,
abruptly. This fissure was richly packed with bones of the sloth and the
large rodent El,.s ,odoni owxs, the bones beginning at near the surface
and continuing down some nine feet, when excavations had to be given
up because of the impossibility of reaching any deeper. This cave had
the appearance of a trap for any animal that wandered into it and cer-
tainly would have proved so for any old or sick animal that had strength
enough to crawl up through the cave entrance. The earth in this cave.
which is the one on the property of Don Gervacio Toraflo near Utuado,
is reddish in color and composed completely of disintegrated limestone.
It is rather coarse in texture and intermingled with it were good-sized
fragments of the walls.
A much different type of cave is the Cueva Catedral, near Morovis.
Also situated on a steep hillside, it occupies the top of a small hill, and
the ceiling'of the cave has fallen through, letting in considerable light.
'This cave has two large entrances and is a large, open chamber filled to
a depth of several feet with earth and many fallen fragments of lime-
stone. At one side there is a deep deposit of fine powdery soil. almost
pure bat guano in spots, sloping rather steeply down from the back wall
of the cave. The natives have removed from this part of the cave a great
deal of the rich soil for fertilizer. Throughout a stratum of several
inches to a foot or more in thickness, this deposit vwas literally packed
with small bones of mammals, birds. reptiles and amphibians. In some
.pots the bones were interlaced almost in hundreds and a quart of earth
required some minutes to pick over. In the crevices between the larger
blocks of limestone and in the irregularities in the cave floor were espe-
cially rich pockets of these bones. Farther up the slope, above the fine







1I2 WNCIETIFic 1' RI IEl' OF PORTO RICO

earth, a large number of skulls, some of them lime-encrusted, were found
beneath a heavy, flat slab of limestone.
Subsequent cave explorations in Cuba and Jamaica have indicated that
owls are to be considered responsible for these large aggregations of bones
of the smaller creatures. The owls spend the day in the caves, where
they cast up in pellets the bones of animals small enough to be swallowed,
and may carry to their perch there the larger species which must be eaten
piecemeal. A cave which is thus the home of owls may, over a period of
hundreds or thousands of years, accumulate an almost unbelievable
amount of hones, to be judged in hundredweights or even tons in some
eases. While the large barn-owl known in Cuba and Jamaica today is
absent from Porto Rico, 1)r. Wetmore has discovered the fossil remains
of a barn-owl among bird bone- collected by me at Utuado, while the
small bare-legged owl ie- common on the island today and probably should
he considered as a factor ill the creation of these cave deposits. (Wet-
more, 1922, pp. 299 and 32:i.)
Isolobo0don wavs Ifundi on the very surface of the floor, in nearly every
case, in caves whih lihad been occupied by the former Indian inhabitants
of thp island. Designs upon the walls of the cave, broken pottery and
ashes attested to the occupancy, and amidst the ashes and fragments of
pottery the scattered bones of this rodent could be found. Also through-
out the great shell-heaps along the coast, especially at Cabo Rojo. an
oeeasional bone of Isolobodon was encountered.
It is likely that the Arawaks or the Caribs carried Isolobodon with
them in their canoes as food, since the remains of this rodent have been
fiiind on the eastern end of Santo Domingo and in the Virgin Islands
associated with human artifacts. Wetmore (19'2.. p. 300) heard stories
of the natives whici hint at the persistence of Isolobodoni into quite
recent times.

given as doubtful records. The first mention of any native mammal
from Porto Rico not a bat is the description of Isolobodon porioricensis
by Dr. 3. A. Allen (1916, p. 19). Fourteen species and subspecies of
)bat4, four of them new to the island, were given in a paper pbnllished on
1ne I ynCOenH1ous Land Mamln ials of Porto Rico by Anthony (1918). No
species have been added since this time.
Four families of bats are represented on the island : the Noetilionidae
witl one species. the Phyllostomidac with ten species, the Vespertilionidae
with one species, and the Molossidae with two species. Porto Rico has
several endemic species and several genera endemic to the West Indies.
These endemic forms are found only in the family Phyllostomidae. The
species of the other three families all have very near relatives on the
continent )or possibly occur there as the same species. No less than five
genera of the Phyllostomidae of Porto Rico are endemic to the West
Indies. The following list of the bats of Porto Rico will indicate this
relationship.:

liemanrks'.-The species of the genus octilio are among the very larg-
est of the New World bats. On the character of size alone, the Port.o
Riiean Xo0lilio may be readily distinguished from all the other bats found
on ithe island. There is ohl one other large bat found in the entire West
Indies area which surpasses it or e\en equals it in size. This bat is
I'.mpy'm frini s'pecr't and it has not been recorded from Porto Rico.
The status of the two forms, lepors',nu and miasti 'sj., lhas not been very
satisfactorily worked out. Two specimens of leporins from Trinidad
are not very different from the series taken on Porto Rico, the Trinidad
.-eeimelnis being somewhat smaller and with the dorsal line less developed.
This large hat was found at hut one locality, in a cave known locally
an the Pied'ra de la C'eva, on the outskirts ol' the little town of Old
ILoiza. on the north coast. The fact that Noctilio had not been reported
fromi Porto Rico before would indicate that its distribution is very local.
Extraets from the field journil of tile expedition will servo to describe
lhe behavior of this interesting bat.,

Iemairkls.-There are two species of the genus Chilonycleris occurring
on Porto RIico. These two forms may be easily separated on the basis of
size. (. parni llii portoricensis is much larger than C. fuliginosa inflata.
It is also apparently a much rarer species and not found in such large
numbers. The nearest relative of porloricensis is C. parnellii boothi of
Cuba, from which it differs in smaller size and more inflated skull. In
addition, the ear of boothli is more pointed and falcate than the ear of
1,orloricensis.
Only two specimens of portoricensis were taken and it was found only
at one place, the Cueva de Trujillo Alto. The type locality for the spe-
eies is the Cueva de Fari, Pueblo Viejo, but although this cave was
visited several times and carefully searched, no portoricensis were seen
there. It is evidently not a common species anywhere, as the two speci-
mens secured were the only ones seen, and the cave where they were
found was visited no less than three times and hunted assiduously in the
effort to secure more. The two specimens were found in an inner alcove
of the cave, off to one side of the main chamber, from whence they issued
with a swarm of the smaller species of Cliilonycteri.f, IMoophiyllus and
the rare Mormoo,ps.
A fossil skull of this species was also found. Among a considerable
collection of fossil bat skulls and limb bones picked up in the Cueva
Catedral, there is one fairly complete skull of C. p. pororicensis. This
skull shows no difference whatever from the skulls of the bats living on
the island today.

General charactler.-Size very small: ears quite highly, narrow andl
pointed, widening abruptly into an ample eminli at base, with two or
three tooth-like projections on external border about midway; tragic of
moderate length, with distinct notch-like infolding in anterior edge;
nostrils simple, without nose-leaf, but having a very low transverse ridge
just baek of nares; nose-pad with a number of low, rounded excrescences
along the margin; lower lip with lateral lobes or folds meeting anteriorly
to form a lappet, median region of lappet papillose; hody everywhere
furred: membranes naked: tail about one-half the length of head and
body, free for terminal one-fourth ; interfemoral membrane nearly twice
as deep as length of tail; clear very long and slender: femur nearly as
long as tibia, both bones slender; humerus strongly bowed; hair of mod-
erate length, soft, denser on back and belly than on neck. stiffer about
face and directed forward; a distinct longitudinal parting in the hair at
anterior edges of ears, and hair on throat lax and radiating in all direc-
tions.
Color.-Two color phases are found in this splcie-- a rich brown
phase and a gray brown phase, the latter seemingly the co('m onllr.

Ilenmarks.-Dr MJ. Allen discovered the presence of two small spe-
sice, of C'ilooclt'eris in Cuba, describing the new one as (. torrei, which
is distinguished from (C. mnicleaCii by the presence of two or three minute
tooth-like projections on the ear, and lower nose-pad with less prominent
protruberanes. and slightly smaller size throughout. The Porto Fiican
subspecies, iinfl /, has the same assemblage of characters which mark
lorrei. and consequently the old designation ol inflacta as a subspecies of
Mia/tleafii had to he revised. The next name available for the small spe-
ies of West Indian Chilo i.ycteris is ftliginosa Gray, 1843, occurring in
S[Haiti. Grav's type is in the British [Museum and Mr. Oldfield Thomas
lias xaminied it and pronounced it to be of the torrel style. while four
sp(e-inens of Chilotyol/eris from Santo Domingo loaned by the Academy
of' Natural Sciences of Philadelphia, as well as specimens from Haiti in
the American AInuseuin, are also similar to lorrei in the details of ear and
nose tiructurte. I(/fla is thus made a subspecies of fOlilinoso, and the
name of the Porto Rican lha should stand as (', ilonirtleri. fuigqiJnoso
in/laia (elehn).
Chilonyclerix I'/iint osa inflata is larger and has a longer calcar than
true fuliginosa of Haiti, and also shows the extreme degree of rostral
inflation for tlhe entire group of small Antillean Chilonycrteris. In addi-
lion to th te characters mentioned, which separate it from warclceayii if
Cuba, in/fl/ta llas a broader palate and shorter, broader ear. C. imacleayii
risee of Jamaica is a larger lat than C. f. ini/l/to and may 1,e distin-
gui.shed by this character.
I secured this hat only in the northern part of Porto Iieo, in the San
J1 ian distlri'l. A specimen taken at Mayaginez ( elhn. 1904. p. 19'1) is







J-1V7TIINIV, WA1 ~ >t,Jb IPORJTO RICO


in the United States National Museum, and Gundlach (18i8, p. 140)
records one which he caught in his house in Mayaguez. Although this
species might he taken anywhere throughout the island, the field work
done by this expedition inclines me to believe that normally it is re-
stricted to a narrow belt along the north coast.
In the Cueva de Fari and Cueva de Trnjillo Alto large numbers were
found, more especially in the latter. This species prefers deep, narrow
fissures or holes in the walls and ceiling and does not often cluster in the
nmre open recesses. When disturbed, the inmates pour out in a rapid
stream and disappear like shadows into some other part of the cave. The
Light is very swift, but, owing to the small size of this bat, may appear
to ie more rapid than it actually is. When frightened from a resting
place, as a rule thie leave the spot with very little reluctance and do not
hover about or make tentative returns. This species was not found in
houses, as MacLcay found the small C'hilonycleris in Cuba. A very
small bat, possibly inflata, was seen at dusk flying over the streets of
Lares. No small young were noted with the adults of this species, al-
thotgh you ng of the other species of bats were quite common at this time
(July).

all the species of this genus, but the skull characters identify the Porto
Ihian specimens with the Cuban series. Froin 3. b. blainuillii of Ja-
maica, 31. b. riol.momenia, has been differentiated by Rehl (1902, pp.
1 G.'-166). the reviser of the genus, on the charmnter of the first 1pp1er pre-
odlar.' "greatly expanded posteriorly." I have examined the same speci-

means which IRehn had. with the advantage of additional specimen.- (the
tltal number of West Indian Mormoops.: 31, as follows: Jamaica, 1.
skins and alcoholics with 12 skulls; Cuba, 4 skins and alcoholics with 4
skulls; Haiti. 1 alcoholic with 1 skull: Mona Island, 5 alcoholics with 5
skulls: Porto Rico. 6 skins and alcoholics with 5 skulls), and find that I
am unable to distinguish more than one form in the lot. The shape of
the first upper premolar varies somewhat with the individual and I can
see nothing to indicate subspecific separation for the Porto Rican animal.
The degree of rostral inflation varies as well.
None of the Porto icean animals sh,,w the intense ochraceou- colorn-
tion attained occasionally by this species elsewhere, but doubtless this i-
a condition due to the small size of the .ceries. and more extended collect-
ing would secure the bright individuals.
Mormoops appears to be a rare bat in Porto Rico. as it was seen in but
one cave, Cnueva de Trujillo Alto, and then only in very small numbers.
One was secured J. ly T after several shots had been fired into a chamber
teeming with Molooplylluts and on later visits, July 14 and 20. a very
few were found t, be hanging in crevices in a small, elevated chamber.
to which it was rather difficult to ascend from the main floor of the cave.
lere it wxas consorting with the smaller C'hilonyclctris and 3Monophylt/1s,
being found mingled with masses of these two genera. When in flight,
which was generally only after all the other bats had departed, this spe--
,ies would alight on the first favorable -spot, seemingly heedless of the
light and confusion or else bewildered by such strange happenings. where
it could be struck with a bit of brush. It is easily the most grotesque ii
appearance of any of the bats on Porto Rico. because of its very peculiar
ears and complexly ornamented lower lip.
With the fossil remains of .Veoplrnles. SNieiodlrmu'ii. Phyllon1ycerLi
and other bats were found three skulls and two mandibles of Mormnoop.o .
The fossil skulls ditrer to no appreciable extent from recent skulls of
I[ormoiops.

]ec/lirs.--The genus Jlonophyillus is known only from the West In-
lies, where it occurs as different species on several islands. The genus
is well characterized, and Mlonophyllus poorlori en.ais is nit liable to be
confused with any other Porto liecan bat. .I. porloricen. differs from
the species of JMoidop/hylllus o neighboring islands bIy its smaller -ize,
having a forearm less than 10 mm. The lMonoophyllfns of .Jamaica has a
larger skull than that f' the Porto ilican species, while the rostrum is
proportionally much shorter and more tubular. i. cu.bans of nulia is
quite similar to 31. ,portr'iceni.s, but the latter may he distinguished by
a smaller skull, shorter rostrum and more rounded hraincase.
This snall hat was encountered in great numbers in the Cneva de Tru-
jillo Alto. where it Intin unered all of the other hats. Here it was clus-
tered in masses. hanging in dleep crevices. or chimneysys," in the ceilinl"
of the cave, and generally appeared to be segregated by sexes. Thus, out
of 83 specimens collected on .lJlv 1-. So were males. This specie' ap-
peared to be rather lotl to leave a localit.y and even when disturbed flies
about in fluttering eiriles several moments before leaving the spot for
good. After several shots had Ieen fired the hats Iwould move on into an
adjacent chamber. Some individuals which were knocked down into the
stream that flowed through the cave lost little time swimming il the edog,'
and crawling- out. Others, which had been knocked down hy means of a
handful of slender branches and were not very seriously injured, crawled
down into a deel fissure between the earth andl the rocky wall of the iave
and behaved very imicih like so many mice. When this species was tiini
about in a wild and distiured condition., I oten noted a metallic buzziiig
sound that seemed to be made by lMoophi lll.s, and yet it was unlike aun
noise that I had hitherto hard made by bats. It was ore suggestive of
the droning flight of a huge beetle, and possibly may have been malde by
individuals with shot-pierced wings. 'The flight of this bat is st'rolig' but
not. particularly erratic or angular.
Monophylllus was found only sparingly in the .'ae\; d Fanri inea
iBayamin. These two localities, C'ueva de Fari andl ( eva de 'Trujillo
Alto, were the only places where Illonophy/llus was taken by this expedi-
tion, but an additional record from the United States IBiologieal Snrvey
gives Cayey a. a third locality.
This species was fiunmd as a fossil in the ('ueva Catelral. A siiigle
fragmentary skull agrees well with skulls of the present-day animal. The
fossil lMofoph/llix was found associated with Ifonoj/iyllus [froler. Phiyl-
lioiyert'i., major and1 other species now extinct.

/li'on'rls.-This large species of Moaoplly'lus, while not found living
today, was apparently contemporaneous with the smaller MI. porloricwrsis
at the time that the cave deposits were laid down. A typical skull of the
smaller oiroriore.sis found in the same deposit with the skull of frater
womld indicate that the two forms were living as distinct species. ITad

this material not been discovered, associated, the natural assumption to
make would account for portoricensis as a descendant of frater. The
relationship of frater and portoricensis is quite close, however, and the
differences appear to be in size rather than in detail. The two may be
distinguished most readily by the greater length and breadth of rostrum
and palate and by the much heavier dentition of frater.
-M. fraltr appears to be the largest species of the genus Monophyllus.
It is larger than -l lucine from the Island of St. Lucia, Lesser Antilles.
having a longer rostrum and noticeably longer tooth-row.
It is quite possible that frater may yet be found living, and only a
longer period of careful and extensive collecting can definitely prove this
point.

mandible, 20.73 (20.2-21.); length of mandibular molar series, 10
(9.8-10.2).
Remarks.-This large, robust-bodied bat may be easily identified in the
field by its peculiar light coloration, narrow interfemnoral membrane, its
muzzle with the low transverse ridge and no upright leaf or process, and
lack of a tail. Next to Noctilio lrporinus mastirus, it is the largest of
the Porto Rican bats. although it is closely approached in size by Artibeus
jamaicensis. From Artibeus, JBraclyphylla may he told by the lack of a
nose-leaf and the much paler coloration.
Brachyphylla cavernarum ranges over a rather extensive area without
any apparent differentiation. Specimens from Porto Rico agree quite
well with specimens from St. Vincent, the type locality, as well as with
specimens from other West Indian islands. Doubtless Bralchypylla
ranges throughout most of Porto Rico, but it was found only along the
north coast and the northwestern parts of the island. Usually it was
found in large numbers if the cave was of any size. It appeared to be
truly a cave-dwelling bat and was not found in any other situation.
It is often found associated with Artibeaus, since the two are very simi-
lar in their habits. Both genera frequently use well-lighted caves and

very small, with low, flattened crown showing protoeonid and metaconid
with a posterior internal cusp, possibly the entoconid.
Li'ccn, arlcs.-S-l ,loderma rI'ufus for over a century stood as a name only.
The habitat of the species was unknown. although it was shrewdly sur-
mised by Dr. -1. Allen (1911, p. 238) that the homeland of the spe-
cies was in the West Indies, and this conjecture accorded with the ideas
of most workers on Amnrican C'hiroptera. The animal was described by
Etienne St. Hilaire Geoffroy in a work on Egypt dated 1813 (see Lyon,
1914, 1. 217), but the type locality was not given. The natural assump-
tion would be that the bat was African. but later workers felt that its
New World origin was not to be doubted. For over fifty years nothing
was added to the description of Geoffroy, and it stood as an animal of
unknown habitat and poorly understood characters until Peters, in 1869,
visited the Paris Musemn atnd examined the type. He found the type
represented by a ilaimaged skin from which the skull had been removed
and lost. 'Peters was deceived by the faulty figure of Geoffroy, and as a
result lie made Stenodermia out to be VFampyrops (Peters, 1869, p. 399).
Later on Peters lhad occasion to examine the type of Artibeuts undallun
Gervais in the anatomical collection of the Paris Museum (Peters, 1870.
1). 132). The similarity between the skull of undatum (the type of
icdatehicm was a skull, the skin of which was supposed to be lost) and the
skull figured by Geoffroy at once impressed Peters, who came to the con-
clinsion that the skull of codatul was tie long-lost skull of Stenoderma
rif, si. This interpretation was evidently accepted by Dobson (1878, p.
.52 ), who wrote that tile type of Steimd.eraI. rufus was represented by a
skin, in bad condition, and a sknll in the Paris Museum. The work of
'cterrs is important because he was able to demonstrate the existence of








-O lENT'll Fl SURIkJY OF POR TO kU)


such nl animal as t1eunodllrma ruf.us and to define its well-marked char-
acters, thus putting' to an end a condition which had allowed rlenloderma
rufe s to be confused with 3olo.ssu.s, rufust and Desn.todus rufus.
Finally, in 1916, Seaoderuai rufus was discovered as a fossil and thl
habitat, in part. at least, of this species was disclosed. Some of the ob-
-nurity of the previous 100 years was dispelled, but there still remains
this interesting condlition. In Porto Ilico this bat is known only as a
fossil, whereas Geolfrov had an animal in the flesh. The fossil material
of this bal was found associated with Xe.ophonles, Phyllooyereris major
and Monopuhllus frater, all known ionly as fossils, and with skulls of
f1 type may very well have come from Porto Rlico: on the other hand.
.'lrn odernia maI be extinc(t on Porto Ii(ic and survive on some of the
adjacent islands.
The relationships of SIeuoderuma rl/fos are well expressed by Miller's
(1907, p. 1(;.) treatment of the Stenoderinimae. The aflinities of the

Specimens collHcled.-60 fragmentary skulls, only a few of which are
nearly complete: 22 mandibles, mostly without any teet1, and small
fragments not worth listing.
Penieari.s.-Phyllonyrleri.s major is so obviously congeneric with poeyi
fhat comparison elsewhere is unnecessary. From poeyi it may be told by
its larger size, more widely expanded braincase and much larger second
upper premolar.
This species was found only as a fossil and in but one cave. It wa~
contemporaneous with Nesoph ones as well as with Slenodentau. rufu.s
and other bats to be found living today. Possibly P. major may be found
as a living bat, the chances for this being very favorable, since P. poeyi
and the species of the related genus Erophylla. occur only in isolated
localities and escape notice for long periods, as witness the rarity, till
recently, of P. poryi and E. sezckorni in collections.
Heretofore, Phyl!oiiyceri.q, with but a single species, has been knownY
only from Cuba. The discovery of a closely related species of this pecu-
liarly West Indian genus upon Porto Rico is an added bit of evidence in
favor of an earlier, intimate connection between the now detached island-.

Remarks.-There is no other Porto Iican bat liable to be confused
with Erophyllht bombifroons. In some characters this species has a super-
firial resemblance to Monlophyllus portoriccnsis, hut there are notable
difflrenees between the two in size, color and fundamental differences in
tooth structure. From the other species of the genus to be found on
other islands, bowmbifrons may be known by the combination of complete
zygomlata. high. rounded braincase rising abruptly above rostral plane,
small teeth. notched tragus, and flaring rim of the external nares.
This brightly colored species was taken only in the Cueva de Fari.
about two or there miles west of San Juan. and was noted in no other
locality. It was found a a small colony, in a chamber to one side of thle
main cave. and there may have been about :35 or 40 animals altogether.
After a few shots, tlh survivors flew out into other parts of the cave and
were lost to observation. Their reddish appearance was apparent under
the light of my acetylene lantern, and generally this species could be thus
di.ttiniuished from the others found in the cave. Eropliylla had segre-
gated itself from the other .species and was found in small potholes or
conc avities in the ceiling of the chamber, a few in each place. Yomun
from two-thirds grown to nearly full grown were collected.

Rema.rks.-The long. lax fur and rich brown color of Eptrexics 'fursc
retimorei are sufficiently diagnostic to mark it off from all the other bats.
Its closest relative, perhaps, is Eple.sirca fulscus cubent, s of Cuba, typo
locality. Trinidad, Cuba, from which it differs but slightly. In the orig-
inal description by Jackson, the Porto Rican animal is given full, specific
rank. On the basis of the improbability of the actual intermingling of
the Porto Rican form with the mainland fuscis or the Cuban f. eube.si-s.
this determination is satisfactory, but on the basis of development and
actual relationship the trinominal is the best expression. Examination
of typical fascus, m iradorensis, cuibeosis, and wehtorei has convinced me
that the relationship is a very close one, and to carry the expression of
this relationship only to the limits of the mainland and then call the
island forms full species hardly seems consistent. Eplesicus /. ivetmorei
)ears especial resemblance to f. m iradorensis from the Chiriqui region of
Panama, having the same, well-built skull, heavy dentition and long
forearm.
This bat was not noted throughout the island, but appeared to be re-
stricted rather to the western half. in the two regions where it was
taken it was a conspicuous bat, and were it generally distributed over
Porto Rico it seems fair to assume more specimens would have been
taken. Both at San German and at Pueblo Viejo it was found in eaves,
using deep crevices and holes in the limestone in much the same fashion
as did Tadarido, being crowded into its retreats in large numbers. The
several colonies located were nearly all females, and practically every
animal was nursing or heavy with a single large embryo. This condition
was noted June 6 and July 6, and while considerable variation in the
development of the young bats was noticed, the majority of them were
at about the same stage of development. At San German. June 6, most
of the young were short-haired and about one-half the size of the parent.
One of those taken proved to be a partial albino, differing from the others
in its almost white coloration.
A bat seen at dusk in Lares was thought to be of this species.
A series of 9 skulls, some of which are nearly perfect, and one man-
dibular ramus of E. f. wetmorei were secured as fossils in the Cueva
Cathedral. These skulls appear to be indistinguishable from those of the
living form. although associated with the skulls were skulls of genera

This bat, said to have been brought from Porto Rico by Mauge, is de-
scribed in sufficiently great detail to make its identification as one of the
large-eared Vespertilionids certain. Very likely it is Corynorhintus, as
the characters given by Desmarest fit this genus very closely, and Gray,
in Cuvier's Animal Kingdom, vol. 5. 1827. p. 97, places it under Ple-
colus. This state of affairs gives plausibility to the hypothesis that
)Desmarest's specimen did not come from Porto Rico, since Corynorhinn.s
has never been taken in the West Indies. Probably Maug6 obtained his
specimen from the mainland and, as was the case so often in the early
days of systematic mammalogy, the described confused the localities.
For this reason I believe that Yespertilio maugei is not truly a Porto
Rican record.

the habitat of which is Jamaica, queried, according to Redman. In the
Magazine of Zoilogy and Botany, vol. 2, p. 501, 1838, Gray gives another
description of this species and states its range as "South America.
(Brasils) : West Indies, (Jamaica)." Dobson, in his Catalogue (1878,
p. 137), places imuioii ts in synon ymy with N. brasilienxis but lists
among his specimens one from Jamaica as "Type of Nyctinomus murinius
Gray." As Dobson had other specimens from Jamaica and was familiar
also with Xycftnoomos miacrotis, the only other species of NA'.. l;,,.I.;......
known to occur on Jamaica, it seems fair to assume the validity of
,to inu, i and of the type locality as well. This being the case. Gray's
name must stand for the small Tadarida generally distributed throngh-
out the Greater Antilles, mlusvcu ts being a synonym of it.
Lyon (1914, p. 217) has discussed the use of Tadarida for Nyctinotaus
;nd it seems best to make this change in generic terms.
RIeioarls.--Taddar-idan uirim is not liable to confusion with any other
P'orto Rican bat with the exception of Molossus fortis. The distinctions
between these two forms are fundamental: the high sagittal crest, the
robust upper incisors completely filling up the intercanine space, the
number of lower canines reduced to 1-1, and the curving dorsal outline
of the skull of MIolossus serving to show a well-marked generic separa-
tion. if the skulls are compared. Superficially, however, the differences
are not so apparent. and as a rule it is necessary to have the bat in hand
in order to determine whether it be Tadarida or Molossus. The best
external characters to distinguish between the two are the following:
Molo.ossis is appreciably the larger and has noticeable strips of fur along
the humerus which Tadarida lacks: it has ears that are much lower and
thicker than those of Tadrilda, a much narrower tragus and more promi-
nent antitragus: males of ]lolos.su.s have a gular gland; the upper lip of
T'uadrida is more tumid and has tra.n sverse wrinklings not to be seen in
Moloss.is: and the fur of JIolossis is darker in color, more velvety to the
touch and mInch richer in appearance.
From the species (of Tada rida to be found on the other islands of the
West Iundie-, iiiuriin is distinguished as follows: from T. antillularain
of the Lesser Antilles by the slightly smaller size of the latter; from
7'. h aaiamiesis of the Bahamas by the larger size and grayer coloration
of that form and rrom 7. iniaroti. of Cunha and Jamaica by the fact
that macfrotli belongs. to that --cetioi of the genus which has ? -2 lower

This small bat is easily the best flyer of the island species. Its flight
is very rapid and under such perfect control at all times that on occasion
very erratic maneuvers are executed. This bat occupies much the same
position among its fellows that the swifts do among the birds. The long.
narrow wings give rapid strokes, and the bat rows through the air, oscil-
Iating from one side to the other, looking at a distance very much like a
small swift. The compact, cylindrical form of the body, the long tail
generally held out straight behind, so that the conmtor of the animal
diminishes from the thickness of the body at the hipls to the point of the
tail behind, and the wings vibrating so rapidly that they often present a
lcnmi-transparent zone along the sides, all combine to give such a charac-
teristic picture that this animal mnay be readily recognized on the wing.
thle closely related 3looss.is being the only other bat on the island with
similar flight.
Tidaridan m oiimn is a dweller in both eaves and loses, seeming to be
one of the most abundant bats on the island. Old buildings frequently
had bats to the number of several hundred spending the day packed into
dark crevices. In eaves these bats chose deep fissures or holes in the
limestone and were packed in very closely. When disturbed they poured
forth literally in a stream. The large piles of droppings beneath such
holes demonstrated the fact of the great concentration in numbers. In
no ease was Tadoricda ever found in small, scattered groups, the social
instinct seeming to bring all of the individuals of a region into large
congregations. The habit of the sexes of keeping in separate colonies is
very marked. ThIis species has a sharp, high-pitched squeak and is rather
noisy when in large numbers.
A very large colony was located in an old, deserted building in San
German. It was a typical old Spanish structure of low, rambling con-
struction, made of brick and wood and with an inner court. In places
it was more or less fallen in. Early in the evening, about 6 :15, we en-
tered the building and were greeted by a great deal of squeaking from
the many dark corners. The noise was made by so many individuals
that it seemed as if we stood in a gigantic beehive, and this squeaking
buzz could be heard even before the door was opened and the building
entered, showing that the bats were beginning to stir about, preparatory
it issuing forth for tlhe night. By seven o'clock, hats were flying about
hlie darkened corridors and rooms in small numbers. Very shortly they
began to come forth in large numbers, and the interior was teeming with
the noisy animals on the wiung. Soon the bats left the interior and began
lo leave by way ,l lthe inneri c rt, which took on the apple arance of a
whirlpool of hats. Issuing from the rooms, they cir'lodl the court, all

going in one direction and at a high rate of speed. A few paIsed np and
over the enclosure at the completion of each lap, until finally nulne were
left. The whole building had the pronounced musky odor seemingly
chalrncteristic of the Molossidae. TadIoridl. seen in other localitie
-lowed a tendency to circle for several moments albot the spot where it
liId spent the day before straightening out the flight and taking a dirmet
course for other feeding grounds.
Females taken .June 7, t1 and 21 contained single, large embiryo.'
nearly ready for birth. No immature animals flying with the adnlt<
were taken. At San German, during, early June, this hat was frequently
seen to re-enter the home crevice after having been awing about thirty
minutes: possibly this was for the purpose of nursing the young.

given in the treatment of Tadarida imurinu. From the related species
of IMolossus, the Porto Rican foris is distinguished by the combination
of the following characters: moderate size (forearm. 40 mmn.), rostrum
not heavy, color dark and molars of normal size.
In addition to the localities recorded under the distribution, this bat
was noted at Lares and at the Preston Ranch near Naguabo, but no
specimens were taken. Because of the impossibility of distinguishing
between 3Joloss.s and Tada.rida when on the wing and in a poor light,
definite records are given only when specimens were collected or the op-
portunities for observation were unusually good. MJolossus fortis appears
to be quite well distributed over the island, although I have no notes for
it in the San Juan district. It was not found anywhere in eaves and
probably is almost strictly an inhabitant of old dwellings, which are
sufficiently numerous in Porto 'ico to afford ample quarters. For this
reason it was not as easy to collect, as it was often impossible to shoot
about the buildings, and in the case of old church buildings the high
ceilings where the bats were in hiding were inaccessible.
The flight of this bat is exceedingly swift and erratic and possibly it
is an even more skillful aviator than Tacdrida mauina. The flight of
these two forms is so essentially identical and the size difference so slight
that there is little to mark off the one from the other.
This bat comes forth while there is vet considerable daylight, and by
early dusk, if there is any large colony of bats in a town, a multitude of
the little animals will be seen pursuing their zigzag courses about the
streets. In the month of June the first bats would begin to appear about
1 p. m. In a quarter of an hour the number would greatly increase and
probably the total bat population would be awing by 7 :30. This bat was
frequently seen leaving the caves of some house in the evening and one
could not fail to be impressed by the intense activity of the small crea-
ture. The bat would drop out from the opening and take a downward
course for five or six feet, then straightening out in the most rapid flight.
Often one could see the head of the bat appear an instant before the
animal precipitated itself headlong, but so quick were the movements
that it was exceedingly difficult to shoot the bat, even when thus warned
to expect its emergence. Not infrequently the animal was not observed
until it appeared as if shot out from the opening in full flight.
A large colony was located in the attic of the lodge building at Ad-
juntas. It was possible to ascend into the attic and by poking into the
crevices between the rafters dislodge tlhe bats. This species is not very
dormant, even in midday, and it was not an easy task to dislodge them.
A nose and pair of Iright eyes would peer out of a crack with a ver\

mouse-like aspect and the owner would dodge back so nimbly as to avoid
all thrusts of the stick. Tobacco smoke blown into a long crevice de-
moralized the tenants and they attempted to move into adjacent nooks
with much scuffling and scratching, accompanied by sharp squeaking.
When animals were knocked down to the floor, if uninjured, they ran
for dark corners with as much agility as a mouse. This bat always at-
tempts to bite if given the opportunity. An intensely musky odor wae
always to be noted about the buildings where llolos-m.s: stayed.

Typc.-No. 14174, Dept. Vert. Pal., Amer. Muis. Nat. Hist. The type
is a skull in nearly perfect condition, being broken only at the extreme
tip of the prcmaxillaries and lacking the auditory bull, dentition well
worn.
Type locality.-The type, as well as a large number of other skulls of
this insectivore, was taken from a cave near Morovis, Porto Rico. This
cave is more or less well known locally as the Cathedral Cave, "Cueva
Catedral."
Distribution.-Known only from Porto Rico. Recorded from Porto
ilico from Hacienda Jobo (near Utuado), Ttuado and MIorovis (Cueva
Clara and Cueva (Catedral).
Skull.-(Text Figs. 17, 18.) Males have skulls considerably larger
than those of females, although proportionally the skulls of both sexe-
are practically identical.6
Skull elongate and narrow, tapering gradually in width from parietal?
to end of nasals, superior outline nearly straight, slightly elevated in
fronto-parietal area; rostrum long, tubular, and strongly convex from
side to side, only slightly narrower outside incisors than at base of zygo-
matic roots, much deeper than wide; nasal sutures not satisfactorily dis-
cernible because of fusion, but apparently nasals are very narrow; inter-
orbital region with sides practically parallel, in males a very slight
widening anteriorly, this whole region flatly convex front side to side:
braincase only slightly inflated, parietals swollen, but interparietal and
supraoccipital regions solnwhat constricted, inflation generally more
noticeable in females than males; very low sagittal crest, higher in males.
ending anteriorly in noticeable supraorbital ridges; lambdoidal crest well
developed, especially in males; noticeable fine wrinkling of lone surface
over upper part of brainease (best shown in type, a female).
Zygomatic arch incomplete, lacking jugal, anterior root a peg-like
process, posterior root a blunt process upon the expanded glenoid: infra-

'The series of crania is divisible into two groups, on the basis of size only, and the
most logical way to account for this is by assuming a sexual dimorphism. No such sex

groups in the series of Cuban Xesopholtfc. stirnll hens 1he impression that the size

much higher than any other tooth of mandible, with an anterior cutting
edge the outline of which is convex; the internal face, passing from apex
to root, seems to rotate to the rear, so that canine appears as if twisted
from right to left: this rotation further expressed by appearance of ex-
ternal mid posterior faces of canine, a narrow shoulder developed at bas,
of posterior face; three premolars subequal, with trenchant triangular
cnsps and narrow heel: three molars of approximately equal size, all with
high tuberculo-sectorial trigonid and broal, flat talonid, the protoconii

Skulls collected.--J7. of which many are nearly complete. lacking only
incisors and bullet.
Mandibles collected.--0, the greatest number lacking only the in-
cisors; also, a considerable number of fragmentary skulls and rami too
badly broken to be worth listing separately.
Ileinarl's.-Three species of the genus Nesophonles have been de-
-cribed-edithae of Porto Rico, micros of Cuba and longirostris, also of
Cuba. Edithae is very much larger than either of the two Cuban species.
fI addition to the size difference, there are cranial distinctions which
have been set forth in detail by Anthony (1919, p. 633). X. m.icru. has
tle first anterior upper premolar noticeably larger than the second,
whereas in editme the anterior upper premolars are equal. y. lonui-

lThe scapula (text Fig. 21) is long and has a breadth equal to about
half its length. The spine is very high, the acromion and metacromion
are well developed and the coracoid is very long and strongly curved.
T'he axillary border is reflected outward to produce a ridge and a deep
concavity paralleling the spine. The anterior superior border is smooth
and regular.

The Ihutierus of Jeso/pholeis bears considerable resemblance to that of
Solenodon, but is even more primitive than the latter, retaining an un-
specialized form and showing little decided adaptation for a fossorial
habit. The Solerodon1l humierl s is much heavier proportionally, antd con-
.qtquently is inch more aiigular in t.he a ittaclhent areas. The HIaitian
animal lacks the suprai roclilear foraien, the head of the huImerus is
mincih more elliptical and thie deltoid ridge is anore greatly expanded.
The' dillerencoes for the most ;part appear to be responsive specializations
to a fossorial habit. Itelationshlip in primitive characters is more clearly
shown by i comparison with (eiteles and Iiemicentetes. where modifica-
tion by peculiar environment has not played a part. The Erinaceus
hunmiierus only approximately resembles that of Vesophontes and does not
show as close a resemblance as the Zalambldoldots cited, but the Gyminnurn
hIl merls bears a \ery strikiingi likeness t, the Cesop.Ihowle humlerus.
Tl'hi arboreal type of hiiitnerns, as exemplified biy T'uli;a, shows such a
parallelismlu with the ]hinertis of S.es ophoiftes tliat the evidence should
not be passed over lightly. The Talpids are too highly specialized in the
fore limb to give a. clues through com lpa prison, except it shounl be noted
that a primitive humerns, sli c as that of Xcsophoutones. has the possibili-
ties for the Talpid spleialization. The more primitive condition of the
Soricid hlniterus, using Crocirlulra is a type, bears significant likeness to
the .Vesoplonles hlmnerlls.

cross-section throughout, and with a slight distal expansion. It has a
conspicuous tublerele and well-marked insertion areas for the snpinator
and pronator muscles. There is a well-defined curve for the extensor
lendon. and the articulating surfaces of the bone, both proximal 11(a

insertion areas are unusually well marked.

('Cretes and Solenodon, while rather closely agreeing with k'cs'o-
lphoufes as to radii, are not proportionally as well equipped for pronation
and supination. Although the bones of these two genera are much
larger, and therefore should be more clearly marked olr for muscle inser-
tion, they are actually smoother than tlhe small radius of .-r'.ophoenic,.
Eriiarc is has a radius quite similar to that of -e.ophouIt'.e, and the
Shrew radius (C'rocidura and Bltrimn.) is also similar.
Although several ribs of Nesophontes were found, mostly from the
anterior part of the series, it is not possible to draw very satisfactory
deductions front the material. The ribs are not very strongly curved and
the greatest degree of curving is at the proximal end. On some of the
ribs the tubercle is fairly well developed, but on the longer ribs the
tubercle facet is wanting or is undifferentiated from the surface of tle
rounded head. The shaft of the rib is strong, compressed, but expanded
distally to form a thickened articulation surface for the Icostal cartilage.
In most cases there is a well-marked groove along the shaft.

lMea.sure, melu.-Sex indeterminable. 9 ( ( ). raiest length, third

Judging from the curvature of the few ribs collected, the body of
XeNophonles must have been deep rather than broad. In the characters
of the ribs themselves, considerable resemblance is shown to those of
'roridura. and to Gyminura. C'enlees, as well, should be included in this
comparison, although in some details, such as the more rounded shaft
and the better-developed tubercle, a decided difference is displayed. The
"',dalodon rib is compressed in a plane at right angles to the plane of
iulnIpression in the Yesioplhonts rib. and this is confirmatory of the
hypothesis that Yesophloonies had a deep body and not a widened-out one
like '1,ol'odon. None of the other insectivores examined have sucrl ;

The sacrum (text Fig. 23) is composed of three vertebrar and is nmch
\wiler at the cephalic than at the caudal extremity. The neural spines
are not fused to lorU a continuous hdorsal crest and they are not very
blibl. The cephalic articular surfaces are of mediimn size, but the cauidal
articuilations are rather small. The hlteral borders curve gently from
tih alh to the third sacral vertebra. The dorsal foraiiiin are very laroe
and the ventral foiramina are fair-sized. In one specimen, probably that
of' an old individual, advanced fusion with the first eaudal vertebra is
shown. The sacrum shows no characters of specialization.
