 edges all convex, well compressed. CTaudal peduncle well com- 

 pressed; length, about two-thirds of least depth. 



Head compressed, flattened sides converging about evenly above 

 and below. Snout conic, surface convex, long as wide. Eye little 

 ellipsoid; center nearly midway in head length and but little ele- 

 vated. Mouth small, gape about two-thirds to eye, and lower jaw 

 very slightly shorter. Maxillary beyond nostril, but not to eye; 

 expansion 2^ in latter. Lips firm. Teeth in about five rows above 

 and three below, with outer row in each jaw largest, moderately 

 slender, expanded and notched at ends. Nostril simple pore at
