280 BULLETIN OF THE BUREAU OF FISHERIES. 
irom posterior margin of orbit; spinous armature of head well developed; a pair of sharp spines between 
nostrils in front of eye; each upper orbital rim with three spine-like serratures; posterior rim of orbit with 
two or three very small spines; two sharp “strong” spines in transverse series behind each upper poste- 
rior angle of orbit, and two in longitudinal series on each side of nuchal region; two strong spines at back 
of opercle, and three along upper margin of opercle, in a series continuous with the anterior spinous 
tubes of the lateral line; a strong humeral spine; a strong spine at upper angle of preopercle, with two 
weak spines in front of and above it, and four below it on the free preopercular margin; teeth in jaws in 
velvety bands, the posterior ones recurved; no barbels: orbital tentacles very small; a short nasal flap on 
each side; lower margin of preopercle with five or six small cirri; middle of each upper jaw with a short 
tentacle; scales of side without dermal flaps; pectoral 1.20 in head, with no prolonged or free rays; ven- 
trals 1.40; caudal rounded, 1.50 in head; longest dorsal spine (fourth to seventh) 2.66 in head; second anal 
spine longest, two in head; lateral line complete; upper parts of cheeks and opercles scaled. 
Color in spirits, grayish brown, mottled with darker; under parts little paler than upper; head 
darkest on lower part of cheek and at upper angle of opercle; edges of lower jaw and chin rather faintly 
marked with narrow dusky cross bands; spinous dorsal mottled, with a conspicuous black blotch in its 
upper part between the sixth and tenth spines, soft dorsal mottled, darkest in front and toward base, 
with a faint broad pale crossband at middle; caudal barred broadly with dusky across base, at middle, 
and behind; anal with an obscure broad bar across middle and on outer fourth; ventrals dusky, paler 
toward base; pectorals with scattered dark specks, forming an indistinct broad bar across inner third; 
axil of pectoral with several roundish white spots, smaller than pupil. 
Two specimens from Calayan, 2.25 inches long. It is with hesitation that we refer these specimens 
to S. nuchalis, as the scales appear to be larger than in that species, and there are some differences in 
coloration and minute orbital tentacles. The species is near S. ballieui (Sauvage), but has a shorter jaw 
and much smaller orbital tentacles. 
PARACENTROPOGON Bleeker. 
267. Paracentropogon longispinis (Cuvier & Valenciennes). 
A single example, 2 inches long, from Cuyo. The pale spot above the lateral line does not show in 
the specimen, which otherwise agrees closely with descriptions and figures of this species. 
268. Paracentropogon indicus (Day). 
A single small specimen from Cuyo, 2 inches long, agrees closely with Day’s original description 
and figure of this species (Fishes of India, p. 155, pl. 38, fig. 2). 
TETRAROGE Ginther. 
269. Tetraroge barbata (Cuvier & Valenciennes). 
One example from Aparri, 2 inches long. 
Family PLATYCEPHALIDA. 
PLATYCEPHALUS Bloch. 
270. Platycephalus indicus (Linnzeus). (Cottus insidiator Forskal.) 
One example, 8 inches long, from Manila. 
THYSANOPHYS Ogilby. 
271. Thysanophys tentaculatus (Riippell). (Platycephalus nemato phthalmus Gunther, also of Bleeker.) 
One specimen from Cuyo, 6 inches long. 
Family PLEURONECTID®. 
PLATOPHRYS Swainson. 
272. Platophrys pantherinus (Riippell). 
One specimen, 3 inches long, from Aparri, northern Luzon.
