snout, ?>i in head; tliumeter of eye, 2^: length of inaxillarv, 4; width 

 of interorbital .space, -t^; heig-ht of dor.sal, 1|; leno-tli of longest anal 

 rays, 2^; pectoral rays, If; ventral raN^s, 2f ; nunil)cr scales in lateral 

 line, 120+ ; between insertion of dor.sal and lateral line, 5; dorsal raj^s,

Snout sharp; compressed; its dorsal outline concave; viewed from 

 above, the outline is rounded. Transverse ridges of head distinct; 

 continued in a straight line from tip of snout to edge of preopercle; 

 median dorsal region of snout with a keel w hich broadens tow^ard the 

 interorbital region; a low curved ridge anterior to no.strils; passing 

 upward and posteriorly, joining interorbital rim above the e3"e, and 

 thence running backward along the top of head and occiput; a pro- 

 nounced ridge extending from the orbit backward above upper edge 

 of opercles. Eye very large; somewhat oblong; equidistant from 

 snout and posterior edge of opercle. Anterior end of mouth just 

 behind a vertical through edge of orbit; angle of mouth below center 

 of pupil. Symphysis of lower jaw" wnth a barbel. Teeth villiform; 

 in patches which grow wider anteriorly. Slit of anterior gill-mem- 

 brane i wider than that of posterior; width of latter equal to distance 

 between occipital ridges. Lateral line following the dorsal contour. 

 Scales with 16 to 19 spin}^ ridges; scales of upper part of head, 

 especially those of ridges, plate-like; w^ith minute spines. First dorsal 

 spine minute; second, long; smooth; ra3's successively shorter. Pec- 

 toral pointed; upper rays longest. Ventral extending to base of anal; 

 its first ra}^ with a short, slender filament. Color in alcohol, brownish; 

 a dark spot on axillary region; a narrow dark band along base of anal. 

 Some carefully made measurements of the t5^pe are here given. 



Length of head, measured from tip of snout to posterior edge of 

 opercle, .67 mm.; length of snout, .32 of head; longitudinal diameter 

 of e3'e, .38; vertical diameter of eye, .31; distance between orbit and 

 lower edge of tran.sverse ridge, .08; interorbital space, .22; tip of 

 snout to anterior edge of mouth, .32; cleft of mouth, .17; length of 

 barbel, — ; wddth of gill-opening, ,49; slit in anterior gill-mem))rane, 

 .14; in posterior gill-membrane, .09; length of second dorsal spine, 

 .70; first ray. .70; last ray, .17; longest pectoral ray, .81; ventral ray 

 with filament, .43; anal ray, .35. 



This species is named for Dr. Kamakichi Kishinouye, of the Jnqj«'rial 

 Fisheries Bureau of Japan. 



^ From this specimen the extreme tip of the tail Ls lost, so the exact numljer of 

 dorsal and anal ravs and the character of the caudal fin are unknown.
