LETTER OF TRANSMITTAL



To His Excellency, Hon. Doyle E. Carton,
Governor of Florida.
Sit:
I have the honor to submit herewith for publication as Bulletin
No. 4, of the Florida State Geological Survey, a report entitled "The
Foraminifera of the Choetawhatchee Formation of Florida" by Dr.
Joseph A. Cushman, of Sharon, Mass. The importance of these
microscopic fossils is becoming more appreciated, especially by oil
geologists, and it is the intention of the Survey to issue from time
to time reports similar to this dealing with the other formation s of
the State.
Reapectfully,
HERMAN GrNTER,
State Geologist.
Tallahassee, Florida,

THE FORAMINIFERA OF THE CHOCTAWHATCHEE

FORMATION OF FLORIDA



JOSEPH A. CUSHMAN



Tlie Choctawhatchee formation has numerous foraminifera, and in
some parts a rich fauna. For general information in regard to the
formation as it occurs in Florida, one should consult the report by
Cooke and Mossom (Florida Geological Survey, 20th Annual Report,
pp. 138-149). Dr, W. C. Mansfield who collected much of the material
used in the present report, recognizes three fannal zones in the Choe-
tnwhatchee. Of these, the lowest, known from the vicinity of Red Bay,
Walton County, carries a very characteristic foraminiferal fauna. The
middle and upper zones are characterized by numerous species of
fornminifera not found in the lowest zone, but there are very few
species that can be used to separate the two, and these are very rare
species, so that it is to be suspected that their occurrence in one or the
other zone is due to lack of material rather than a real distinction in
the fauna. The relative abundance of certain species which are re-
corded from all three zones is very striking in one or the other of the
zones, and may be used for distinctions not indicated in our table of
occurrence,
The two lower zones are characterized by cold or cool water species
as is the case with the Mollusca, although the basal zone which carries
but few species of Mollusca is one of the richest in foraminifera. The
upper zone carries a somewhat warmer water fauna characterized
particularly by the development in large numbers at some stations of
Amnphistegina lessonii d'Orbigny, a species of warm shallow waters.
These are front Leon and Washington Counties.
One point in regard to the material from Bay County should be
noted. There are two lots used in the present paper. That front the
R. L. Gainer farm on Econfina River, about one mile below Econfina
bridge is reported by Mansfield as belonging to the upper zone. The
foraminifera of which only twelve species were noted seem to agree
with this determination. The other locality in Bay County is from

Bryant Scott's farm, one.quarter mile above mouth of branch enter.
ing Econfina Creek, near bridge at Econfina. This yielded a richer
foraminiferal fauna of eighteen species and varieties, of which but
two are common to the two localities, and these both occur in all
three zones. The fauna of the second locality is much more closely
related to the lowest zone of Walton County than to either of the
others.
LOWEST ZONE
This zone exposed in Walton County east of Red Bay and, as noted
above, possibly in Bay County, has numerous species and varieties of
foraminifera peculiar to it. The following species are not known from
the middle and upper zones:
Proteonina difflugiformis (H. B. Dentalina, various species
Brady) Elphidium sagrum (d'Orbigny)
Robulus americanus (Cushman) BIlimina gracilis Cushman, n. ep.
R. americanus, var. spinosus Nonion pizarrensis Berry
(Cushman) Loxostomum gunteri Cushman, n. sp.
II. catenulatus (Cushman) Siphogenerina lamellata Cumshan
Saracenaria acutauricularis
(d'Orbigny)
The following additional species are rarely found in the other
zones:
Bolivina marginata Cushman Bolivina floridana Cushmani
Altogether there are more than sixty species and varieties of fo-
raminifera recorded from the lowest bed, all of which are character-
istic of cool waters and waters of some considerable depth.

MIDDLE AND UPPER ZONES
As already noted, there are very few species of foraminifera to dis-
tinguish these two zones except Amphistegina lessonii d'Orbigny
which seems to occur only in the upper zone. There are however a
number of species which will distinguish the middle and. upper zones
from the lowest one. Some of the most characteristic of these are
given here:
Textularia agglutinans d'Orbigny Bolivina plicatella Cusliman, n. sp.
*T. mayor Cushman *B. pulchella (d'Orbigny), ver.
Quinqueloculina, various species primiliva Cushman, n. var.
Pseudopolymorphina rutila *Diseorbhi mira Cushman
(Cushman) D. vilardeboana (d'Orbigny)
*Nonion grateloupi (d'Orbisny) D. consobrina (d'Orbigny)
Virgulina fusiformis Cushman, n. op. *D. valvulata (d'Orbigny)
Some of these species indicated by an asterisk are found in fairly
warm waters off the coast of Florida today. All these are most com-
mon in the upper zone.





FORAMINIFERA CHOCTAWHATCHEE FORMATION OF FLORIDA. 7

RELATIONSHIPS OF THE FAUNA
The relationships of the fauna are interesting. There are numerous
species not known elsewhere or at least only in the Miocene of ad-
joining regions of the Gulf Coastal Plain of the United States, al-
though they have closely allied species elsewhere. Some of these
such as Pseudarcella arenata and Virgulina gulteri have their near-
eat relatives in the Miocene or Uppermost Oligocene of Europe.
There are other species which seem identical with species found in
the Miocene of the Gatun formation of the Panama Canal Zone, the
Miocene of Cuba, and of Santo Domingo. Other species are identical
or closely allied to species of the Miocene or Pliocene of the Cali-
fornia region.
Of the species which are still living, those of the upper bed par-
ticularly, are represented in the waters of the present coast of Florida
or the West Indies. There are other species which are known at the
present time only from the Western coast of South America or ex-
tending up the Southern coast of North America. These species ap-
parently died out in the Miocene in the Western Atlantic, and have
persisted only in the Pacific or else migrated to the Pacific at that
time.
A table is given showing the distribution by stations, numbered to
correspond with the list which follows (pp. 13-14). Nearly all the
species and varieties are figured to make the work of the most possible
use to those working with the fauna. My thanks are due to Miss
Margaret S. Moore for her care in the drawing of the specimens for
the plates, and to Miss Alice E. Cuslhman for painstaking work with
the manuscript.
References are given to other works where complete references to
the literature of the species may be found and only references to such
works as may be needful are given here. The Choctawhatchee fauna
was described in an earlier report (Cushman, Bull. 676, U. S. Geol.
Survey, 1918), but the known fauna has been greatly enlarged by
the study of this later material, and the newer classification is here
used. References to the earlier work are given so that material named
from the previous paper may be brought up to date.
My thanks are due to Mr. Herman Gunter, State Geologist of
Florida, for his aid and co-operation in the preparation of this work,
and to Dr. W. C. Mansfield of the U. S. National Museum for supply-
ing most of the material on which the present paper is based. The
holotypes are to be deposited in the collection of the U. S. National
Museum, and paratypes of new species and duplicates of other species
in the collections of the Cushman Laboratory at Sharon, Massachu-
setts and the Florida State Geological Survey at Tallahassee, Florida.

DESCRIPTIONS OF SPECIES

Family SACCAMMINIDAE
Subfamily Saccammininae
Genus PROTEONINA Wiliatnson, 1858
PROTEONINA DIFFLUGIFORMIS (H. B. Brady) (7)
Plate 1, figures I a, b
Test free, consisting of a single, elongate oval or pyriform chamber
with a more or less distinct, tubular neck, usually tapering gradually
from the body of the chamber, which is undivided; wall fairly thick,
of sand grains of variable size, firmly cemented or in small specimens
with an excess of cement and fairly smooth; aperture circular, simple,
terminal.
Length of figured specimen 0.25 mm.; breadth 0.15 mm.; thick-
ness 0.10 mm.
This species seems to be rare in the material examined although
it is easily overlooked on account of its small size and indistinct ap-
pearance in the general material. The specimen is compressed, but
as the apertural end is broken the compression may be secondary.
The only specimens are from E. Gomillion's place, Red Bay, Wal-
ton County, and from Jim Kennedy Branch, also near Red Bay.
Genus URNULINA Gruber, 1884
URNULINA COMPRESBA Cmhman, n. ap.
Plate 1, figures 2 a, b
Test free, small, compressed, slightly longer than broad, greatest
width at about the middle, basal end somewhat angular, apertural
end broadly rounded; wall of a single layer of sand grains firmly
cemented; aperture large, rounded, slightly at one side of the axis
of the test.
Length 0.25 mm.; breadth 0.20 mm.; thickness 0.12 mm.
Holotype-(Cat. No. 371068, U.S.N.M.). From Choetawhatchee
marl, on Harveys Creek about 12 miles S. E. of road from Tallahassee
to Bloxham, Leon County, Florida, collected by W. C. Mansfield.
This seems to be the first record of this genus as a fossil. The very
large aperture, compressed test and acute basal end in side view
should distinguish this species. It is rare in the collection, but is
easily overlooked on account of its small size and its color. The only
other species of the genus is recorded from the coast of Europe.
Genus PSEUDARCELLA Spandel, 1909
PSEUDARCELLA ARENATA Cushman, n. op.
Plate 1, figures 3 a, b
Test free, about twice as broad as high, plano-convex in side view,
dorsal aide strongly convex, ventral side flattened and slightly con.






FLORIDA GEOLOGICAL SURVEY-BULLETIN FOUR.-


cave in the middle, circular in outline; wall very thin, composed of
distinct sand grains firmly cemented, somewhat chitinous; aperture
circular with a simple flattened tooth.
Diameter 0.25-0.30 mm.; height 0.15-0.18 mm.
Holoype--(Cat. No. 371069, U.S.N.M.). From Choctawhatchee
marl, of E. Gomillion's place, Red Bay, Walion County, collected by
Julia A. Gardner.
Besides the type locality, the species was found in material from
Jim Kennedy Branch, Red Bay, Walton County; Double Branch,
about 6 miles east of Jackson Bridge, Leon County, and on R. L.
Gainer's farm, on Econfina River, Bay County.
This is a very distinct species of small size and constant in its
characters. Specimens are fairly numerous when the material is care-
fully searched, but it is easily overlooked on a hasty examination.
The genus is known front the Upper Oligocene of Europe at rather
widely separated localities of Germany, France and northern Italy.
This is the first record for it in the Western Hemisphere, and it should
be found in the Miocene to the northward of Florida.

Test elongate, tapering, somewhat compressed, the periphery
rounded; chambers inflated, increasing in height toward the aper-
tural end; sutures distinct, depressed; wall rather coarsely arenaceous,
but smoothly finished on the exterior; aperture an elongate slit in a
well-marked depression of the inner border of the chamber.
Length usually less than 1 nmm.; breadth 0.25-0.35 mm.; thickness
0.15-0.25 nnm.
This species was not noted in the material from about Red Bay,
but occurs as noted in the table from several stations in Leon, Liberty,
and Calhoun Counties. I have recorded it from the Miocene of Vir-
ginia and Maryland, and from the Uppermost Culebra formation of
the Panama Canal zone, as well as elsewhere in the Oligocene.
It is a common species in the West Indies in comparatively shallow
water.

Test slightly longer than broad, compressed, periphery subacute,
sides strongly divergent; chambers distinct, comparatively few, fairly
high, the earlier ones strongly overlapping: sutures distinct, slightly
depressed wall finely arenaccous, smoothly finished; aperture elon-
gate, in a definite groove at the base of the inner margin of the last-
formed chamber.
Length 0.60-0.75 nmm.; breadth 0.35-0.45 mnn.; thickness 0.22-0.25

I have previously recorded this species from the Miocene of Florida
in the above reference. Some of the specimens are evidently Textu-
laria mayor which in its young stages sometimes resembles T.
gramers. It is the most common species of the genus in the Florida
Miocene, and occurs in Walton, Leon, Liberty and Washington
Counties.

Textldaria gramen (in part) CusJIMAN (not c'Orbigny), Bull. 676, U. S. Geol.
Survey, 191B, pl. 9, figs. 2, 3 (not fig. 5).
Test compressed, increasing rapidly in breadth, especially in the
microspheric form, initial end rounded, apertural end obliquely
truncate; chamber often indistinct, periphery of the later chambers
each with an elongate, conical, hollow, spinose projection, often
broken at the tip, those of the early portion directed backward, the
later ones extending outward; sutures only slightly depressed, curved;
wall arenaceous, of angular sand-grains with much fine cement, sur-
face smoothly finished; aperture low, elongate, at the inner border
of the last-formed chamber, in a reentrant of the border, with a thin
lip above.
Length up to 1 mm.; breadth 0.35 amm.; thickness 0.12-0.15 mnm.
This species was originally described from recent material col.
elected about the Tortugas. It occurs also along the east coast of
Florida. The Miocene specimens are very similar to the living ones
but are less accelerated, the early chambers usually being without
spines, some of them not developing the spines at all in immature
specimens but they can be distinguished by the form and association
with mature specimen.

This species is rather common in the Choctawhatchee marl, and I
have specimens from Leon, Liberty, Bay and Washington Counties.

TEXTULARIA FLORIDANA Crshman

pl. 1, fig. 7; Boll. 104, U. S. Nat. Mua., pt. 3, 1922, p. 18, pl. 2, figs. 11, 12.
Test elongate, two or three times as long as wide, much compressed,
periphery entire or broken, in the adult with the sides nearly parallel,
initial end rather sharply pointed, apertural end broadly rounded or
truncate; chambers numerous, thickest near the center, increasing
somewhat in height toward the apertural end, the peripheral portions
thin walled and often broken away; sutures nearly at right angles to
the periphery, slightly if at all depressed; wall finely arenaceous,
smooth; aperture small, rounded, at the base of the inner margin of
the last-formed chamber.
Length of recent specimens nearly 1 mm. Figured specimen 0.40
,Iu.; breadth 0.20 inm.; thickness 0.10 mm.
While there are numerous records for this species from along the
Florida coast and the West Indies, it is very rare in the Miocene. The
only specimen is from Gully Sink, Washington County, Florida, col-
lected by W. C. Mansfield.
The specimen has the periphery entire and the peculiar form of
the initial end suggests that possibly this species belongs to the group
of biserial forms derived from Gaudryina by acceleration of develop-.
Ilent.

Variety differing from the typical form in the larger size and much
greater proportion of the uniserial stage and reduction of the biserial
portion as well as in the relation of the two, the last-formed chambers.
of the test often being greater in size than the entire biserial portion.






FORAMINIFERA CHOCTAWHATCHEE FORMATION OF FLORIDA. 19

Length of the fossil specimens slightly less than 1 timm.; diameter
'0.20 mm.
Specimens are rare in the Choctawhatchee marl, a few specimens
being found on Harveys Creek about 11/ miles S. E. of road from
Tallahassee to Bloxham, Leon County, and a single specimen from
Gully Sink, Washington County, all collected by W. C. Mansfield.
The few fossil specimens are not as well as developed as the recent
ones of the Florida coast and the West Indies, and apparently the
greater development of this form in the West Indian region has taken
place since the Miocene.

Plate 1, figures II, 12
There are a very few mail arenaceous specimens which seem best
referred to Brady's species. In the waters adjacent to Florida at the
present time, Quinqueloculina fusca sees to be absent and the com-
mon species are Q. agglutinants d'Orbigny and Q. bidentate d'Orbigny.
However, Q. Jusca occurs on the Pacific coast of America with a fauna
related closely to the Choctawhatchee marl of Florida.

Test elongate, about two and a half times as long as wide; chambers
distinct, peripheral border rounded, apertural end projecting; sutures
somewhat obscured; wall ornamented by numerous longitudinal
costae which, instead of being uniform, are usually irregularly
toothed throughout, giving a peculiar roughened appearance to the
test; aperture with a thin lip and a single tooth.
Length of figured specimen 0.35 mm.; breadth 0.18 mm.; thick-
ness 0.12 mm.
This is a fairly common species in shallow water in the Florida
and general West Indian region, but has not been previously recorded
as a fossil. It is very rare in the Choctawhatchee marl.

end projecting considerably beyond the aperture of the previously
formed one, the apertural end very slightly, if at all, projecting, side
view concave; sutures distinct; surface matt; aperture with a slight
lip and an elongate tooth, often slightly bifid at the tip.
Length of figured specimen 0.43 mi.; breadth 0.30 mm.; thick-

marl at Jackson Bluff as Spiroloculina limbata d'Orbigny. A study of
topotype material from Castel Arquato, Italy with the original figures
of d'Orbigny shows that later authors have greatly mixed these two
species.
No further specimens were found from the Florida Miocene.

distinct, curved; wall smooth; aperture with a slight neck, rounded.
Length 0.40 mm.; breadth 0.20 mm.; thickness 0.08 mm.
This species is very rare in the Choctawhatchee marl. Bagg has
recorded it from the Miocene, Choptank formation, of Pawpaw Point,
Maryland as "Spiroloculina tennis." It occurs also in the Miocene,
Gatun formation, of the Panama Canal Zone. Czjzek's specimens
were from the Miocene of the Vienna Basin, and a study of my own
specimens from that area show that our specimens are identical. The
original figure is not well drawn although in the adult of some speci-
mens of the Vienna Basin and elsewhere there is a tendency for the
last two or three chambers to be formed almost in a single plane.
The more normal form is that figured here.
Sigmoilina elliptica described by Galloway and Wissler from the
Pleistocene of California is the same, as shown by a comparison of
topotype material with the series from the Vienna Basin.

I have already recorded this species from the Choctawhatehee
marl from 1 mile south of Red Bay, Walton County (Bull. 676, U. S.
Geol. Survey, 1918, p. 50, pl. 10, fig. 8). In the more recent collec-
tions, it has occurred in some numbers at the following localities
Jim Kennedy Branch, I mile east of Red Bay; John Anderson's farm,
'Y mile east of Red Bay; and E. Gonillion's place, 1 mile cast of
Red Bay. Like Robulus americanus, it is a good marker for this par-
ticular portion of the Miocene, as it was not found elsewhere in other
counties of Florida. It occurs in the Miocene, Gatun formation, of
the Panama Canal Zone.

but apparently never occurs in any considerable numbers. It occurs
in the Miocene of Cuba and Santo Domingo, and the Ploistocene of
the Panama Canal zone. It is rare in the Choetawhatchee marl, occur-
ring as rare specimens in Walton County only.

Jim Kennedy Branch, 1 mile east of Red Bay, both in Walton County,
and at Darling's Slide, about 21/ miles, airline, southeast of Clarke-
ville, Calhoun County.
This species is elesely related to P. californica Cushman and Stew-
art from the Pliocene of California. That species has broader and
less oblique sutures in the adult, and its early stages in this respect
are much like the Florida species. When they are seen together, it is
very easy to separate the two.

of the last-formed chamber.
Length up to 0.55 nm.; diameter 0.20 mm.
This species was originally described from the Miocene, Monterey
shale of California. Most of the Florida specimens are like the orig-
inal figure with the greatest width toward the apertural end, but
there are a few evidently old age specimens in both regions like that
figured here in which the later chambers fail to increase the diameter

It is very abundant at other stations cast of Red Bay, but does not
occur in the other counties so far as observed.
This is an unusual form of Brdimina, in that there is a tendency to
become somewhat biserial and to have the aperture drawn away from
the periphery toward the center of the face, but it does not become
truly terminal.

tentatively to this species of d'Orbigny. It is unlike any of the recent
material now living off the coast. The Uvigerinas are so variable and
in such a state of chaos that reference to type material with large
series must be made before very intelligent work can be done in
straightening out this group.

This species was described from the Choctawhatchee marl, from
I mile south of Red Bay. It has occurred in some numbers in the
more recent collections from Walton County, but was not found in
material from the other counties, and should be a good marker for
this phase of the marl.
The type specimen is an extreme one, and the costae are not always
as high as our present figure shows.

Test minute, elongate, triangular in transverse section, the pe*
riphery somewhat lobulate; chambers distinct, those of the last-
formed portion becoming more distinct and remote; sutures distinct
and depressed; wall ornamented with longitudinal costae on all but
the last-formed chambers in the adult; apertural end drawn out into
a short tubular neck and slight phialine lip.
Length usually less than 0.50 mm.; diameter 0.15-0.20 mm.
This species is common in the West Indian region at the present
time, and probably derived from Angulogerina byramensis Cushman
of the Lower Oligocene of the Coastal Plain region. It shows much
variation in its ornamentation from heavily costate specimens to
nearly smooth ones as shown in the figures.
Specimens are fairly common in the Choctawhatchee marl of Cal-
houn, Leon, Walton and Washington Counties.

Test unequally biconvex, dorsal side somewhat arched, the ventral
side slightly convex, flattened or even somewhat concave, periphery
not lobulated, composed of about two and a half whorls; chambers
distinct, six to eight in the adult whorl, slightly inflated; sutures

This species is widely distributed in the present waters of the West
Indian region, and is the most common species of the genus in the
Choctawhatchee marl of Florida, and occurs in the Miocene of the
Coastal Plain northward.
There are specimens from Calhoun, Leon, Liberty, Walton and
Washington Counties.

Specimens of this species which is so common in the present waters
off Florida are rare in the Choetawhatchee marl. The only specimens.
are from Leon and Liberty Counties. This species with its neat, flaring
cone, strongly curved, limbate sutures and coarse perforations is dis-
tinct from any other species of the genus in the collection. It is.
probable that the specimen referred to D. vilardeboana (Cushman,.

This species is rare in the West Indies at the present time, and a
single specimen was found from the lower bed at Alum Bluff, Apa-
lachicola River, Liberty County.
The peculiar ventral side, rounded, keeled periphery and strictly
limbate suturea will distinguish the species.

the ventral aide strongly papillate especially in the middle umbonate
area and along the sutures, in some specimens with papillae entirely
covering the ventral side; aperture ventral, between the periphery
and ventral umbo at the base of the chamber.
Diameter up to 0.75 mm.; thickness 0.25 mm.
Holotype-(Cat. No. 371079, U.S.N.M.). From Choctawhatchee
marl of John Anderson's farm, % mile east of Red Bay, Walton
County, collected by W. C. Mansfield for whom the species is named.
Besides the type locality, it is abundant at other stations in Walton
County as well as found in Bay, Calhoun, Leon and Liberty Counties.
It is one of the most abundant and characteristic species. It was
probably recorded as Rotalia beccarii (Cushman, Bull. 676, U. S.
Geol. Survey, 1918, p. 66, pl. 24, fig. 2), and as Pulvinulina repanda
(1. c., p. 66, pl. 23, fig. 2).
It is closely related to Eponides peruvican from the west coast of
South America but has a much more ornamented test.

Test usually somewhat ovate, biconvex, periphery subacute and
keeled; chambers distinct, later ones rapidly enlarging and flaring,
inflated somewhat on the ventral aide; sutures limbate dorsally,
oblique, raised, ventrally depressed, nearly radial; wall smooth ex-
cept for the raised sutures and on the ventral side the last-formed
chamber with numerous large perforations; aperture at the base
of the ventral edge of the chamber, low.
Length up to 1.50 mm.
In the adult the chambers of this species often become very ir-
regular. It may be confused in the young with E. repanda but in the
adult the two are very different. It is widely distributed in the recent
oceans but there are few records in the fossil state, none from forma-
tions older than the Miocene. There are a number of specimens from
the Choctawhatchee marl from S. D. Johnson's place near Woods,
Liberty County, and a very few from Gully Sink, Washington County.

Variety differing from the typical in the number of chambers
which in the variety rarely have more than ten in full grown speci-
mens, the shorter broader chambers on the ventral side, the almost
entire lack of beading at the sides of the chambers, and the lack of
thickening of the sutures on the dorsal side.

depressed on the dorsal side, strongly on the ventral, gently curved;
wall smooth; an elliptical area of clearer thinner wall near the aper-
ture which is below a slight lip on the ventral side.
Length up to 0.75 mm.; breadth 0.55-0.70 amm.; thickness 0.20-
0.30 mm.
d'Orbigny described this species from the West Indian shore sands,
and it is fairly common in the region and off the Florida coast. The
species is abundant and well developed in Walton County, and less
so in Bay, Calhoun, Leon and Liberty Counties. There is much varia-
tion in the relative length and breadth due to the expansion of some
of the later chamber.

by Julia A. Gardner. It occurs also in Liberty and Walton Counties.
This is a distinctive species, but may easily be overlooked on account
of its small size. Specimens from the dorsal side resemble the young
of Eponides mansfieldi, but the ventral and peripheral sides quickly
show the differences. The species is named for Mr. Gerald M. Ponton

Family GLOBIGERINIDAE
Subfamily Globigerininae
Genus GLOBIGERINA d'Orbigny, 1826
The various species of the genus Globigerina used in a restricted
sense are in such a chaotic state that it is difficult to treat most of
them intelligently. A study of the types with large series of topotype
specimens is necessary to straighten out the confusion now existing.
There is a very considerable difference in the early and adult stages
in most of the species, and unless good series can be obtained, de-
scriptions based on a few specimens are worth little. A number of the
forms were figured in muy earlier work (Bull. 676, U. S. Geol. Survey,
1918, pli. 12, 13), and while some of these were not named or only
with a question, they must remain in this unsatisfactory condition
until some one available to the types can make a species study of
this genus.

Plate 12, figures 3 a-c
Truncatuliua flordana CUSHMAN, Bull. 676, U. S. Geol. Survey, 1918, p. 62, pl. 19,
fig. 2.
Trunctulinra lobatula (WALKER and JAcoB), vnr. ownata CusHMAN, 1. c., p. 61, pi.
18, fig. 1, 2.
Test trochoid, biconvex, dorsal side less convex than the ventral,
periphery acute, keeled; chambers numerous, ten to twelve in the
adult whorl; sutures distinct, limbate and raised on the ventral side,
fused at the center into an umbonal mass; wall coarsely perforate;
aperture extending along the dorsal aide of the chamber margin.
Diameter up to 0.75 mm.
The types of this species were from 1 mile south of Red Bay. It is
probably the same as the var. ornata noted above. The relation of
these forms to those of Planulinr floridana should be studied, as they
may represent the megalospheric and microspheric forms of a single
species.

CIBICIDES AMERICANA (Cushman)
Plate 12, figures 5 a-c
Truncarulina americana CusnMrn, Bull. 676, U. S. Geol. Survey, 1918, p. 63, pl.
20, figs. 2, 3; pl. 21, fig. 1.
Test plano-convex, dorsal side nearly flat, ventral side slightly
,convex, periphery subacute: chambers numerous, eight to ten in the
adult whorl, rather rapidly increasing in size; sutures distinct, slightly
limbate on the dorsal side especially in the earlier chambers, de-
pressed on the ventral side; wall smooth, finely perforate; aperture
peripheral and extending onto the dorsal side, with a slight lip.
Diameter up to 0.75 mm.
This is a common species in the Miocene and Oligocene of the
Coastal Plain region. It is not common in the material, but was noted
from Bay and Liberty Counties.

CIBICIDE8 CONCBNTRICA (Cdnhman)
Plate 12, figures 4 a-c
Truncaudina concentric CusuHAN, Bull. 676, U. S. GeoL Survey, 1918, p. 64,
pi. 21, fig. 3.
Test nearly plano-convex, dorsal side nearly flat, ventral side con-
vex, periphery subcarinate; chambers distinct, seven to nine in the
adult whorl, the inner end on the dorsal side with a definite proximal
portion, fusing with adjacent ones to form a concentric band about
the middle and more or lees separated by a series of depressions;

sutures deep on the ventral side, slightly limbate and lush on the
dorsal side; wall smooth, finely perforate; aperture largely dorsal
with a thin lip.
Diameter up to 1 mm.
This is one of the most common species in the Choctawhatchee
marl of Florida occurring in material from Bay, Calhoun, Leon, Lib-
erty, Walton and Washington Counties.
In its adult stage, this is a very well marked species, but the early
stages are similar in some respects to C. americana.
CIBICIDBS LOBATULA (Walker and Jatb), var. ORNATA (Cuahman)
Truncarulina lobarla (WALKEt and JACOe). var ornata CUSHMAN, Bull. 616, U. S.
GCol. Survey, 1918, p. 61, pl. 18, figs. 1, 2.
Test differing from the typical form in the ornamentation, es-
pecially the well developed bands outlining the chambers on the-
dorsal side.
The type specimen of this variety is from Coes Mill, Liberty
County, and a single additional typical specimen has occurred in the'
collections from Jim Kennedy Branch, 1 mile east of Red Bay,
Walton County. More material of this form is necessary to be sure-
of its relationships.

CIBICIDES BBFULGENB (Montfert) (7)
In the earlier paper (Bull. 676, U. S. Geol. Survey, 1918, p. 61,.
pl. 18, fig. 3), this species was recorded from Coes Mill. No additional.
material has been obtained.

CIBICIDEB VARIOLATA (d'Orbinry)
This species was recorded in the earlier paper (1, c., p. 62, pl. 10,
fig. 3) from Jackson Bluff. No other specimens were found in this
later material.

Genus DYOCIBICIDES Cushman and Valentine, 1930

Dyacibicides biaeriaUs CUSH AN and VALiNTINE. Contr. Dept. Geol, Stanford
University, vol. 1, 1930, p. 31, pl. 10, fig. 1, 2.
Test fairly large, the early portion close coiled, later in a spreading
biserial series of plano-convex chambers, the dorsal, attached aide,
flattened; seven or eight chambers in the last whorl, chambers not
inflated, but becoming inflated in the biserial portion and greatly
enlarging; sutures in the early coiled part, limbate and not depressed,
in the biserial portion continuing the limbate character on the dorsal
side but becoming deeply depressed ventrally; wall distinctly per-





FORAMINIFERA CHOCTAWHATCHEE FORMATION OF FLORIDA. 63

forate; aperture in the early coiled portion, peripheral or slightly
dorsal, in the uncoiled portion, an elongate slit at the outer edge of
the chamber at the line of attachment, often elliptical, with a slightly
raised lip.
Length up to 1.25 mm.
This species has been recently described from material collected
off the California coast. The Florida specimens seem identical. They
occur in material from Calhoun, Leon, Liberty, Walton and Washing.
ton Counties.
The perforations are much finer than in most of the species of
Cibicides noted above. The later chambers are often irregular, but in
adult specimens usually becoming biserial.

Family PLANORBULINIDAE
Genus ACERVULINA Schultze, 1854
ACERVULINA ef. INHABEMNS Schultze
There are a few attached specimens from Leon County that prob-
ably should be referred to this species. None of them are complete.
