The osseous dorsal ray is strong, finely serrated, as long as the 

 head, without snout. There are two and a half longitudinal series 

 of scales between the lateral line and the root of the ventral fin. 

 Body compressed, oblong, its depth is two-sevenths of the total 

 length (without caudal), the length of the head nearly one-fourth. 

 Snout of moderate length, a little longer than the eye, which is 

 one-fourth of the length of the head ; interorbital space convex ; 

 upper jaw overlapping the lower. The anterior barbel is a little 

 shorter tlian the posterior, which is as long as the eye. Dorsal fin 

 considerably lower than the body; its origin is somewhat behind 

 that of the ventral, and midway between the end of the snout and 

 the root of the caudal. Anal fin low and small. Eork of the 

 caudal fin of moderate depth. Brownish above, silvery below, the 

 membrane between the scales brown ; a deep-black band, half as 

 broad as a scale, runs from the snout through the eye to the end of 

 the middle caudal rays. Top of the dorsal fin black.

The osseous dorsal ray is very slender and smooth. The height 

 of the body is contained thrice and one-third in the total length 

 (with the caudal), the length of the head five times and a half. 

 Barbels small. A silvery streak along the side, a small black spot 

 above this streak, on the sixth series of scales. ( Val.)

 The osseous dorsal ray is of moderate strength, its stiff portion 

 being three-fifths as long as the head ; its serrature is verj- con- 

 spicuous, though fine. There are t^vo and a half longitudinal series 

 of scales between the lateral Kne and the root of the ventral fin. 

 Body strongly compressed, its depth is contained thrice and a half 

 in the total length (without caudal) in males, and thrice and one- 

 third in females. Head of moderate size, its length being a little 

 less than one-fourth of the total (without caudal). Snout rather 

 short, convex, scarcely as long as the chameter of the eye, which is 

 contained thrice and two-thirds in the length of the head ; ui)pcr
