(without caudal) ; head of moderate size, its length being one-fourth 

 or rather more than one-fourth of the total (without caudal) ; snout 

 rather short, scarcely obtuse, as long as the diameter of the eye, 

 which is more than one-fourth of the length of the head ; barbels 

 of moderate length, longer than the eye. The origin of the dorsal 

 fin is nearly opposite to that of the ventrals, and midway between 

 the end of the snout and the root of the caudal. Silvery, with a 

 large deep-black blotch on the side of the end of the tail.

The osseous dorsal ray is rather coarsely serrated and rather strong, 

 its stiff portion being as long as the head, without snout. There are 

 three longitudinal series of scales between the lateral line and the 

 root of the ventral fin. Body compressed, oblong, its depth being 

 one-third of the total length (luithoid caudal) ; the length of the head 

 is contained thrice and four-fifths in it; snout rather obtuse, as 

 long as the diameter of the eye, which is two-sevenths of the length 

 of the head; barbels nearly of equal length, and as long as the 

 ej'e ; upper jaw overlapping the lower ; interorbital space narrow, 

 flat. The dorsal fin is considerably lower than the body ; its origin 

 somewhat behind that of the ventral, and nearer to the root of the 

 tail than to the end of the snout. Anal fin moderately deep ; its 

 rays not reaching, by far, the root of the caudal, if laid backwards. 

 Body uniform silvery.
