The osseous dorsal ray is slender, finelj- serrated. The height of 

 the body is nearly equal to the length of the head, and one-fourth 

 of the total length (to the end of the middle caudal rays). Thi-ee and 

 a half longitudinal series of scales between the lateral line and the 

 root of the ventral fin. Eye large, a little longer than the snout, 

 and two-sevenths of the length of the head. Caudal fin deeply 

 forked. Coloration uniform.

 Scales minute. The length of the head is about one-fifth of the 

 total (without caudal). Snout broad, of moderate length, the eye 

 being rather nearer to its end thau to that of the giU-cover ; barbels 

 small ; margin of the lower lip straight. Origin of the dorsal fin 

 midway between the end of the snout and the root of the caudal, 

 somewhat in advance of the root of the ventral. The osseous dorsal
