332 Fretp Museum or Natura History — Zoétoey, Vor. X. 
Body rather robust, posteriorly compressed; head depressed, wider 
than deep; snout short, 3.65 to 4.25 in head; eye 3.2 to 3.8; interorbital 
2.2 to 2.65; mouth small, the cleft scarcely lateral; teeth pointed, in 
bands in the jaws, the outer ones somewhat enlarged, curved inward; 
scales rather small, cycloid, the circule strongly developed; 8 longitu- 
dinal rows of scales between base of dorsal and base of anal; origin of 
dorsal over middle of base of anal or slightly posterior to this point, and 
somewhat nearer tip of caudal than posterior margin of eye, the 
base of its last ray slightly behind vertical from base of last ray of 
anal; caudal fin rounded; anal fin inserted midway between the tip of 
snout and tip of caudal or slightly nearer the former, its margin convex, 
the length of the base equal to the greatest width of head; ventral 
fins small, about as long as diameter of eye, reaching vent; pectoral 
fins moderate, failing quite notably to reach base of ventrals, 1.6 to 1.8 
in head. 
Color brownish, sides more or less speckled with darker; dorsal and 
caudal with or without faint, dark spots; a black stripe from under side 
of caudal peduncle to end of caudal rays usually present, forming an 
intramarginal bar; on some specimens there is a similar bar on the 
upper lobe of the caudal fin, although less distinct. In life the upper 
parts of the body are grayish with shades of pink, and the belly is pale 
and also has a shade of pink. The fins are all reddish, and the base of 
caudal and anal are deep red. 
Of this species we have 17 specimens, ranging in length from 35 to 
50mm. All are from the upper course of a small creek at Toro Point.
