A COLLECTION. OF FISHES FROM SUMATRA.
By Henry W. Fow er.

During the late summer and autumn of 1901 Mr. Alfred C. Harrison, Jr.,
and Dr, H. M. Hiller formed an important zodlogical collection while pursuing
their explorations in Sumatra. Most of the reports on the different groups have
already appeared in the Procerpines of the Academy, and as the fishes comprise
a large part of the material they have demanded corresponding attention.

But two localities appear on the labels. With the exception of a few fresh-
water forms taken at Batu Sanekar, Tanah Datar, in Padangsche Bovenland, at an
elevation between 1500 and 3000 feet, the specimens were secured in the markets
or environs of Padang. Many are food-fishes, evidently of importance, though no
particular information concerning the fisheries, local names, ete., has been preserved.

The collection was submitted to me for examination by Dr. Samuel G. Dixon,
President of the Academy, to whom I am indebted for this opportunity of studying
East Indian fishes. At that time I was at Stanford University, assisting Dr. Jordan
with the work on his Japanese fishes, and later the United States Fish Commission
with their report on the Hawaiian collections. When first examined, the colors,
which had been well preserved, were noted, as the fishes had all been prepared in
arrack or rice-rum. After being placed in alcohol they soon more or less faded.
Through the courtesy of Dr. Jordan I had the opportunity of examining and com-
paring the fine collections in Stanford University. From the other well-known
ichthyologists located there I also received many courtesies, especially from Dr.
Oliver P. Jenkins, who freely placed his collection of Hawaiian fishes at my dis-
posal. Iam also indebted to Dr. Barton W. Evermann, for suggestions and com-
parisons with Hawaiian forms. Dr. Seth E. Meek has also kindly forwarded notes
on his collection of Aden fishes. Finally, to the naturalists of the Academy I wish
to express appreciation for many courtesies, more especially to Mr. Witmer Stone
and Dr. Henry A. Pilsbry. To these gentlemen I am under many obligations.
Mr. Stone has not only granted numerous and varied favors but also freely offered
advice and excellent suggestions. Upon returning to Philadelphia I found it neces-
sary to entirely revise the original manuscripts written at Stanford University,
more especially as the library and museum of the Academy offers so many facilities
for consultation and comparison. At present the material is contained in the
Academy with the exception of a series of duplicates left in Stanford University.
The latter includes several cotypes.

Difficulty, as usual, has been experienced in the identification of a number of
_species, owing to the short, incomplete or unsatisfactory accounts, with little relation

or attention to geographical distribution. Many forms said to range throughout the
Indian and Pacific Oceans should be examined and compared by means of abund-
ance of material before such views can be established as absolutely final. My own
acquaintance with the Japanese ichthyic fauna has at least convinced me of its great
difference from the East Indian, but few forms straying up in the warm southern
current. So far as one may judge at present that of the Indian basin has much in
common, but just what exhaustive material will indicate remains to be seen. The
work of the early writers on Red Sea and East African forms still needs the most
careful and scrutinizing attention, as it forms the basis of much of the work of
their successors also in other regions. In some cases I have been led to renounce
their decisions, due in larger part to incongruities and differences accruing in the
works of the latter. Polynesia, Micronesia and Australia also indicate different
faunas, though they also display considerable East Indian infusion.

In matters of nomenclature I have followed the code of the American Ornithol-
ogists’ Union, with several exceptions. These have.already been noticed by Drs.
Jordan and Evermann. They concern the names of males having precedence over
names of females when occurring on the same page, and the spelling of names.
These conclusions appear to me valid. However, I do not accept the views of Dr.
Jordan regarding the selection of the first species as the type of a composite genus,
unless the author or first reviser has so indicated. Elimination is now so generally
accepted by the majority of American naturalists that its rejection can only lead to
confusion. I might also add that all names spelled differently, such as Zenodon
for Xenodon, etc., are regarded as different.

Body elongate.

Head broad and strongly depressed. Snout broad and flattened. Eye small,
and well anterior. Mouth broad, and with rather thin papillose lips. Teeth
minute, rather sharp, and in broad bands in jaws. A broad crescent-shaped patch
of fine teeth on vomer with a slight projection posteriorly. Anterior nostrils in
short tubes near edge of snout, but closer together than posterior. Posterior slit-
like, behind bases of nasal barbels midway between anterior and front margin of
eye. Interorbital space broad, flattened, and slightly elevated, especially poster-
iorly. Nasal barbel reaching almost opposite edge of gill-opening. Maxillary
barbel not quite reaching tip of pectoral spine. Outer mental barbel reaching
about first two-fifths of pectoral spine. Inner mental barbel reaching base of
pectoral spine. Fontanel shaped like a plumb-bob, rounded posteriorly, and not
quite equal to space between two nasal barbels. Interparietal fontanel about
equal to eye.

Gill-rakers slender, moderate in number, pointed and not as long as filaments
on first arch.

Skin rather smooth. Lateral line somewhat obsolete along middle of side to

Ventral inserted well behind origin of dorsal and reaching past origin of anal.
Caudal elongate and rounded. Anal papilla long.

Color in arrack dark blackish-olive above, lower surface brown. Vertical fins
blackish-olive. Pectoral and ventral brownish, darker above. Indistinct traces
of vertical series of pale dots on sides of back. Barbels blackish. Peritoneum

Length 114 inches.

Type No. 27,280, A. N.S. P. Padang.

This fish, originally described by Valenciennes, is said to have the head,
measured to end of occipitial process, 42 in total length of body, including caudal,
and fins with 67 dorsal and 48 anal rays. The Formosan fish figured by Drs.
Jordan and Evermann as Ch/arzas fuscus (Lacépéde) is certainly different. A com-
parison of the type with four cotypes with same data, and measuring 74 to 104
inches, shows dorsal ranging from 60 to 63 and anal 50 or 51 rays. It is, however,
in the more slender or elongate body that olzvaceus differs from related species.
Space between occiput and dorsal was found to be 24, 22, 24, 22 and 27 in head,
measured from former point to tip of snout. Gull-rakers 5+ 4 on first arch of one
of cotypes. Possibly records for Chlarzas lzacanthus in Sumatra should go with
this species.

nuchal keel. Coronet high, its upper surface concave, with two lateral and one
posterior tubercles, and also an elevated prominence springing from ridge in front.
Below latter, on each side of head, a round tubercle. Interorbital space with

median compartment of spaces on side of trunk from base of pectoral to tail. Body
marked everywhere with numerous minute whitish dots. Fins pale, their bases
dark, especially that of dorsal.

Length, measured from top of coronet to tip of extended tail, 54 inches.

One example. This species is close to Hzppocampus kuda Bleeker,’ which has
also been recorded from Priaman and Sibogha,? and with which it may prove identi-
cal. However, it has one more dorsal ray, and the color is entirely different from
that given in the original description. My example also has more caudal rings.
The Japanese example placed by Messrs. Jordan and Snyder® with H. £uda may
still be different. It differs from my specimen in such points as its agrees with
Bleeker’s, though its coloration is different from either. /zppocampus kamphylo-
trachelos Bleeker* is the only other species known from Sumatra. It differs in
having twenty dorsal rays.

Color faded in alcohol, pale or dull brown above, and with many narrow incon-
spicuous dark brown longitudinal bands arranged close together, formed by a dark
tint on each scale. Spinous dorsal dark gray, becoming dusky above. Soft dorsal
with its upper portion dusky. Caudal grayish. Pectoral pale, base dusky, and
other fins whitish. Lower surface of body silvery-white. Peritoneum silvery.

Length 11+ inches.

One example. This species originally described from Batavia by Bleeker was
referred to Sphyrena forstert Cuvier with doubt,’ and other examples were subse-
quently also referred to it from other islands in the Kast Indies.” Dr. Giinther
figures a fish certainly referable to S. forsterz, from Tahiti, which does not agree
with my example.* It shows 126 scales in the lateral line, and the eye is about
32 in the snout. Furthermore his description gives 90 scales for the lateral line,
and if not an error is certainly a different species. Sphyrena toxeuma has 115
scales in the lateral line, counting the few on base of caudal, and the eye is hardly
over 2 in snout. Dr. Giinther also describes a fish from Calcutta which may be
identical.*

Two examples. This species has been confounded under the name Apogon
frenatus by authors. Valenciennes’ account and figure! agree well with Bleeker’s,
but Day’s figure® represents a different fish. The latter certainly represents the
examples before me, agreeing in every respect. Afogon vittiger Bennett‘is proba-
bly close to if not identical with Afogon frenatus Valenciennes. Apogon melano-
rhynchos Bleeker’ also has claims, in part, to separation. Apogon frenatus Giin-
ther,” judging by the incomplete description, may be the same as that of Valen-
ciennes, but the examples described and figured later’ are. close to if not identical
with Day’s figure.

One example. This species is close to Ophzcephalus pleurophthalmus Bleeker;,!
differmg however in color. Sides without the large ocelli of that species, but about
six large dark blotches below lateral line, like those in Bleeker’s figure of O. luczus.*
Pectoral barred, in this case agreeing with O. polylepzs Blecker,® but that species is
said to have longitudinal dark bands or lines on dorsal and anal, and sides without
dark blotches. O. urophthalmus Bleeker* is probably the same as O. pleuroph-
thalmus from Borneo.

(Spzrztalzs, belonging to air or breath. Applied as Ophzcephalus is said to live
in mud-pools and rise to the surface before it becomes sun-baked to take in air at times.)

Two examples. Bleeker recognized three varieties of Premnas bzaculeatus.
According to his diagnosis this species approaches near semzczncta of Cuvier,’ but
both the original figure and that by Bleeker* do not agree, as no dark lines are
indicated running down from the saddles above. Furthermore, the saddles are of
altogether different pattern. They do not extend as low, the second blotch hardly
extends on spinous dorsal, and last does not entirely encircle caudal peduncle.

Close to Halichwres poecila (Lay and Bennett) from near Riu Kiu. This was
identified with Jules (Halicheres) harloffiz Bleeker by that distinguished naturalist.
However, he apparently had two forms united under ar/offiz, one of which repre-
sents the examples before me. Aar/offiz is figured later, though the description
applies to annulatus. The complete circle or ring on the lower side of the head is
the chief character for the distinction of axnzlatus.

One example. Closely related to Thalassoma hardwicke (Bennett).! It differs
in blackish-tipped pectoral and presence of an oblique black band before base of
pectoral. Bleeker’s figure agrees with me/anochir, except that he does not show the
pectoral with a blackish extremity. Zhalassoma dorsale (Quoy and Gaimard) has
been identified with hardwecke, though it does not appear to have a broad rosy
lateral band extending along side of trunk to caudal peduncle. /u/zs semzfasctatus

said of /ulzs (/ulis) urostigma Bleeker.

2; caudal 1; interorbital space 3 in eye.

Body elongate, compressed, oblong, greatest depth about middle of belly.

Head elongate, compressed, oblong, and of more or less equal depth. Upper
profile nearly horizontal, and surmounted by a thin rather high fleshy flap or crest.
Snout nearly vertical, broad, convex, and slightly produced beyond mouth. Eye
far forward, nearly impinging on upper anterior profile. Space between its lower
margin and corner of mouth a trifle less than vertical diameter. Mouth low,
inferior, broad, its corner reaching below posterior rim of orbit. Teeth in a narrow
comb-like band in each jaw. Mandible with a strong canine on each ramus. Lips
rather thin, but fleshy. Nostrils well separated, and lower with three or four short
fleshy filaments. A thin fleshy tentacle above eye equal to three-fourths its diam-
eter. Interorbital space narrow, slightly concave.

Gill-opening rather large, membrane broad, and free across rather broad isth-
mus. Rakers short, weak, not numerous, and much shorter than filaments.
Pseudobranchiz well developed.

Spinous dorsal shorter than soft dorsal, also lower, spines of more or less
uniform height, flexible, and well separated from soft fin by a deep notch. Soft
dorsal joined to caudal posteriorly by a membrane. Anal preceded by two small
flexible spines hardly distinguishable from rays, and margin of fin distinctly incised
between rays. Last anal ray free from caudal peduncle posteriorly. Caudal
elongate, rounded. Pectoral broad, rays just below middle longest. Ventral
inserted below posterior portion of crest on head.

Color in arrack uniform pale brown. Side with about eight pairs of indistinct
dusky vertical cross-bars, and on each several short pale blue dark-edged horizontal
bars formed in lateral series. Spinous dorsal gray, blackish on outer portion and
edge. Soft dorsal gray with about six dusky inclined lines extending across. Anal
gray, darker on outer portion and with a blackish edge adjoining a submarginal
narrow blue line or band. Caudal with lower portion of fin dusky, greater part of
fin gray above and crossed with about five narrow brown cross-bars, also finely
marbled. Pectoral and ventral pale brownish.

Length 5 inches.

Type 3 No. 27,807, A. N.S. P. Padang.

Also five others, ?, cotypes. The females have no crests and lack the sub-
marginal anal line.

SOLEIDA.
248. CyNOGLOssuS Os sp. nov. Plate XXII, upper figure.

Head 31; depth 32; D. about 102; A. about 4—76; caudal 8; space between
tip of snout and upper ne 24 in head ; moun cleft 51; upper eye 54 in space to
tip of snout; interorbital space 54; scales in lateral line, from above branchial
aperture to base of caudal, about 86; about 40 scales in a transverse series at
deepest part of body; 12 scales between lateral line at same point.

Body elongate, greatly compressed, sinistral, and greatest depth would fall
about first two-fifths of length of fish. Tail long, tapering narrowly posteriorly.

Head large, profile evenly rounded above and below. Snout rather long, com-
pressed and rounded. Eyes small, close together, and upper nearly altogether in .
advance of lower. Posterior margin of lower eye a little nearer gill-opening than
anterior margin of upper eye is nearer to tip of snout. Mouth large, its cleft hori-
zontal. ‘Teeth rather fine, sharp pointed, and in bands only on dextral side of jaws.
Sinistral side of jaws with a labial fringe of small fleshy flaps. Tongue rather
thick, rounded and little free. Upper nostrils damaged. Lower nostril a small fleshy
tube below and anterior to lower eye, or hardly below middle of upper. Inter-
orbital space rather narrow and flattened.

Gill-opening small, membrane broad and forming a broad fold over narrow
compressed isthmus. Rakers none. Gills small, filaments small.

Scales small, ctenoid, and spread over entire body, except on fins. Lateral
system of mucous pores double along trunk, median series begins near tip of snout
and runs direct to caudal. Upper series confluent with this at its origin, and again
about midway between upper eye and gill-opening, extending along upper portion
of body close to and just below dorsal fin, then out on fifth ray from caudal. A
system of mucous pores runs down from intersecting series, between eyes and gill-
opening, and across side of head. Also another series of pores from front of eye
obliquely down to lower margin of snout. No pores on dextral side of fish.

Confluent with caudal are long dorsal and anal, former divided at first by
anus so that first four rays are separated from rest of fin. Caudal rather long
and pointed.

Color in arrack, sinistral side pale olive, finely mottled with darker. Dextral
side a livid whitish or brownish-white. Fins pale brown.

Length 5 inches.

Type No. 27,816, A. N.S. P. Padang.

One example. It is close to C. sumatranus Bleeker, and agrees with He same
author’s figure except that there is no oblique series of tubes before the eye.
Seventy scales are given for the lateral series while my example shows about
eighty-six scales in the lateral line.
