 tip ; eye 3 3/5 ; maxillary i 4/5 ; interorbital about 3 1/2. 



Body elongate, well compressed and greatest depth appar- 

 ently at dorsal origin. Caudal peduncle compressed, least 

 depth about half its length. Head conic, pointed, rather 

 broadly convex above and becomes scarcely constricted below 

 convexly. Snout long, convex and its length about 7/8 its 

 width. Eye circular, high and a trifle anterior in head. Mouth 

 large, well inclined so that profile more oblique than that 

 of snout above. Mandible large, protruding. Maxillary long, 

 slender, more or less concealed and reaches a little beyond 

 front edge of pupil though not quite to middle. Nostrils su- 

 periorly lateral on snout, posterior larger and in crescent. In- 

 terorbital space rather broadly convex. Preorbital large, its 

 width but a trifle less than its length, and latter i 1/5 in eye.

 slender, without grinding-surfaces. Scales moderately small, 

 disposed in lengthwise rows parallel with 1. 1. and not crowded 

 before dorsal. L. 1. of simple tubes, continuous and a little 

 decurved at first. Dorsal origin little nearer caudal base than 

 snout tip. Anal inserted just behind last dorsal ray base.
