n 1926, the Flord State Road Department engaged
m mas ig a road-cut immediately east ofthe Chpola ,iver,
near riama2, in Jackson Couty. During the course of
this operation a n-ber of fos.lized fish remains were
recovered, of which one was described as a new species of
utlanus by Dr. William K. Gregory (1930). The unde-
scribed balance of the material was placed m storage,
where it remained util 1957, when the Florida Gological
Survey moved to new and permanent quarters. Amongthese
identified specimens has proved to be an esmple of a
beryciform fish.

The n-erous foss-l and liv-g genera which are as-
signed to the Order Beryciformes (Berg, 1940), although of
widely variant structure, diverse adaptation, and consequently
complex taonomy, are quite generally treated as a natural
assemblage. Great phylogenetlc importance has been at-
tached to the group (Gregory, 1933; Reg., 1911, nd Starks,
1904; among others) because of the common possession by
its members of a combination of characteristics inediate
between primitive "ssospondyl and advced spiny-rayed
teleosts. The beryciform fshes were well established and,
it is evident, of wide marne distribution around the world
by upper Cretaceous times. Notwithstanding, the details of

DESCRIPTION

The dehcate specimen, Identified by the Florida Geo-
logical Survey No. V-5776, and delving from thelower prt
of the Oligocene iaranna himestone, lacks parts anteriorly
and anteroventrally of the head, and of others dorsally alg
the left flank. I, however, -s preserved without either ap-
preclable compression or distortion and comprises about
two-thirds of an individual, which, whencomparedwithholo-
centr1d beryciformes, is of relatively elongate body habit.
The dorsum and venter are not longitudinally keeled, and in
transverse sectlonthebodyis of regularly ovate outline. On
t . . .. I gl .


estimated, standard length, 250; head length from rostral
tip to posterior border ofopercular spine, 74; and mamum
body depth (not exceeding). 96

The skull is indicated to have been somewhat longer
than deep. If the above approx-mations of si.e are correct,
the head, relative tothe standardlength, is small, and in this
character the fossil compares more closely to Holocentrus
andMyr st than toother related Recentgenera. Impres-
sion on the trzx of the orbital surfaces of the parethmods

The occipital face of e neurocraniu extends down-
ward and backward from the posterior edge of the skull roof
an angle of approximately45 from the horontal (fig. 2).
The skulls thus prolonged in a spino-occipltal development
greater than that displayed by the skulls of hvng relatives
with which comparison has been made. The supra-occlptal
crestls produced backwardlyands neither elevateddorsally
nor eendedanteriorly Inthe mdhne of the roof. This fact,
coupled with evidences of deep and completely roofed post-
temporalfossae, suggests stronglythat the cranal insert-ons
of the epaalbodymusculature were confinedto the posterior
surface of the skull. Insofar as canbe observed, the foramen
agnum is bounded ventrally by a vertebra whxch s firmly
nkylosed to the more anteriorly lying bas.-occpital. The
exocclpitals, which do not contribute to the formation of the
occipital condyle, form the lateral margins of the same
endocranlal opening and if, in fact, they do not meet each
other dorsally m the mldhm, only the narrow inferor ex-
treaty of the supra-occpital spine can intervene. The
ventrolateral extent of the exoccaptals Is unknown. How-
ever, ndorsalaspect, because of the spno-occipital devel-
opment of the skull, the posteroventral parts of each 12e
horizontally on the underlying bones and appear narrow and
attenuated. Anteriorly the exocc.pitals gradually -den and
flare dorsally in a concave posterolateralydlrected face.
Remanns of both eplotic elements are preserved Those on
the r-ght side comprise the broad, trangularly exp-ded,
post-temporal process and the more anter-or dorsolateral
amna, which meeting the dorsal wing of the pterot-c, form
the posterior port-on of the roof of the post-temporalfossa.
The fragment of the left eplotlc Is that anterovertical part
const.tutng the meslalwall of the left post-temporal fossa.

centrlds examined. the losses are posteriorly deepened and
teir floors are contnuedas grooves, convergent toward the
foremen magnum, across the posterodorsal faces of the
exoccpltals (fig 3).

The exposure of the ntercalar (op-sth.otl of Nelson,
1957)on the poster ace of the skull is Lmited to the proc-
.,es serving the ventral point of attachment for the post-
temporal bone. This s apparently situated belowthelateral
third of the width of the post-temporal fossa. The element
does not possess a mesally directed spihnt apphed to the
exocclptal. Laterallythe Intercalar extendsforwardacross
fully one-half the length of the otto region, foorng a deep
concavity immediately below the artcular facet of the
hyomandibular. Similar butless welldeveloped depressions

the posteror open of the jugular. c l andthe foremen for
the glossopharyngea nerve, and their anteror and dorsal
walls serve as areas of orIgln for at least the adductor
hyomandlbularis and adductoropercul muscles.

The dorsally and anteriorly succeeding pterotic,
sphenot0c, pro-otzc, and alsphenotd bones in the specimen
are either damaged or poorly exposed. However, the doro-
laeral flange ofthe pterotc andthe hghanterodorsal amina
of the'sphenot-c encompass a relatively large, lateral tem-
poral fossa which provides or0gn for the dplator operculi
and levator palate muscles. As the region is exposedonthe
left side, the lateral wall ofthe jugular canal and trgemgno-
facahls chamber Is missing, but the pro-otc is mnlated
posteroventrally and forms a port-on of the anterior wall of
the audtorybull The out-t urnedp of ths part ndcates
a flat, laterally facing, membraneous area external to the
saccular region.

Two elements of the infra-orbital ser-es of bones are
preserved -ntact on the right side (fg. 4). These, situated

Of the visceralskeleton, the possession of two supra-
m llary bones s show. Although lying In approximately
correct position on the left side of the specimen, t must be
presumed that these elements are displaced from tne right
and as thus interpreted display the same configuration and
relationships as the corresponding supra-maxillaries of

ad the th m anteriorlamella ofthebone is thus farlybroad.
The characterstc external rib of the bone s well developed,
and situated near the posterior border of the bone. The

vertical porton of this rb below the level o the operula
process pro3ets lateral n a practically true transverse
plae. Canals for the passage of branches of the hyomandi-
bular nerve emergebothdorsallyandanteriorlytothis ridge.

The preoperculum Is a short, exceedingly deep ere scent
of bone.whch displays neither a sharpilorward angulation of
Its mter1orpart nor a posteror spine. The thlckness of the
anterIor border of the bone complments the transverse in-
lination of the vertical hyomandabular rib andthe posteror
margins of the lam1nae bounding the vertical preopercular
mucous channel are finely dentate throughout their extent.
A smgle vertical series of scales underlies the posternor
arg-n of the preoperculum andoverlies the anteror portion
of the operculum me longitudinally ornamented expanse
of the operculum behind these scales is deeper than long
with generally concave, dentate margins above, and below
posterior spinous process.

The remains of at least eight spinous rays of the dorsal
fn are to be observed. Of these the foremost one preserved
is the largest. These facts denote a long-based sp.nous
dorsalfin composed of I0 or more rays orig-nating aboveor

posterorly exposed apcal field displays a nuclear angle of
nearly 180'. Parallel and longtudhnally directed grooves
(numbering about four in one m.llmeter) traverse the ex-
ternal surface of the part. The ribs between the grooves
project as teeth along the posterior border of the scale and
their sides may be obliquely striated.

this tame, of the same identity as the single holocentrd from
the Ocala limestone of Jackson County, Florida, described
by Conrad (1941) -der the name Holocentrites ova1s. To

the Olgocene specimen permits revision of the diagnoss of
th0s genus, as follows: A relatively fusiform holocentr- d
with a m-axmum body length of about one-fourth the total
length a vertebral formula of 11 + 14 + 1 = 6. The fish
resembles Mypti the strength of the principal and
fewness of the radiating frontal ridges, the correspondlgly
good defAnition of the mucous channels, the expanded post-
temporal process of the epiotic, the protubernt lips of the
laterally directed membranous face of the au.dtory bulla,
the deeply channeled and weakly ornamented infra-orbital
bones, and the simple crescentic and nonspnous preoper-
culum. It differs from f and is slmllar to Holo-
centrus in possessmgabroad, double-headed hyomandlbula;
but is distinct from the two noted huvng genera byvlrtueof
a relatively greater spino-occpltal development and fusion
of a vertebra to the bas0-o1cpital, which prevents the two
exocclpltals meeting each other In the midhne below the
foramen magnum.

The Holocentr.dae date from the early upper Creta-
ceous when such referred genera as Homonotxchthys,
Traohlohthyodeos, and C from Turonian horloons

to the present time aren't frequent but indicate a continuous
ex-stenee. A more complete representation of the group,
the detailed study of these and available specimens, ad
recognition of either morphologically or temporally older
antecedents wouldfacilhtate reconstruction of the phlogenetlc
h-story of the family, In the absence of such object1,e data
however, recourse must be taken in the analysis of certain
obvious osteological characteristices selected because of
avallbihlty to examnatxon on paleontological mnterals.

rad.at.ng ribs, a nonspInous, crescentic preoperculum
short, high, and single headed hyound bula; and hormal"
premaxillary. The second condition, characterized by
Holocentrus, displays much reduced mucous channels;
prncpairontal crests very broad th numerous radiating
ribs, a spnous, sharply angulated preopeiculum, broad,
double-headed hyo..ndibula; and prema illary w1th highly
developed ascending process. While, as impled n the
literature, Holocentrus may be more advanced toward the
"true percolds" than M by reason of the splnous
preoperculum and more protrusxle premaxilary, the two
adaptations can be traced without question back through the
Tertiary nto the Eocene The upper. Cretaceous holocentrd


ma4llary with low ascending processes. The phylogeny of
the Holocentridae consequently has been pictured (Conrad,
1941) as an early Tertiary divergence of the myriprstme
and holocentrne 1hneages from a single holocentr1 d stem of
Cretaceous origin.

Homonot-ehth s f s too poorly -o4 for comment, but
in degree of development of mucous channels and frontal
crests Trahchthodes and Holocentrates are not radically
d 4fferent from M s and C114 4 would seem to

the dlstlnctveness of the two "subfamhal"' groups for the
entire known history of the family By this latter view, the
sngle-headed hyomandlbuae of M and the more
protrusile premaxll11 of Holocentrus would be regarded as
adaptive morphologlc dlastinctlons of the visceral skeleton
whose selective values were established only during post-
ocene times. Some degree of support would seem given to
this opinon(oral commun-cat-on from W.A. Goslne) by the
andHolocentrus. The --

Fossil fishes n general are of rare occurrence m
nature. Corroborative experimental datahave notbeenfond
but t has been tdelyassumed that therate of decompoaston
of the dead bodes of these animals Is comparatively rapid
der aerobic conataons. Conversely, while not and.cative
of life habitats, the best preserved skeletons are generally
attributed to reduction environments (cf. Rayner, 1958).

The Marianna limestone, of lower Oligocene age, has
been described (Moore, 1955) as a 15-foot thick layer of
soft, cream to white, masesve limestone. It has a lmated

of these writers to the relatxonsh1 p of sedlmentparticle size
