 The osseous dorsal ray is strong, serrated behind, as high as the 

 body. There are eleven and a half scales in an oblique row from 

 the base of the ventrals to the dorsal. The height of the body 

 is more than the length of the head, and contained thrice and 

 three-fourths in the total (without caudal). 8nout covered with 

 small, thorny tubercles. Barbels well developed, equal in length. 

 Eyes midway between snout and operculum. None of the anal 

 rays prolonged. Coloration uniform. (M'C'I.)

The long simple dorsal ray is scarcely stronger than the others, 

 and not serrated. The height of the body is contained thrice and 

 two-thirds or thiice and three-fourths in the total length (without 

 caudal), the length of the head four times or four times and a half. 

 Head rather compressed ; interorbital space convex, its width being 

 much more than the diameter of the eye, which is contained from 

 four times and a half to five times and a half in the length of the 

 head. Snout variable in length ; mouth inferior, horseshoe-shaped, 

 with thick lips ; barbels well developed, the lower being longer than 

 the ujjper and than the eye. The eye is situated before the middle 

 of the length of the head. There are three and a half longitudinal 

 series of scales between the lateral line and the root of the ventral 

 fin. The origin of the dorsal fin is a little nearer to the root of the 

 caudal than to the end of the snout, and a little in advance of the 

 ventral. Anal narrow, twice as high as long, nearly reaching the 

 caudal when laid backwards. Caudal fin a little longer than the 

 head, deeply forked, the length of the middle rays being two-fifths 

 of that of the outer longest. The pectoral extends to the tenth scale 

 of the lateral line, and is somewhat longer than the ventral. Greyish 

 green, each scale witli darker margin ; fins black towards the edge.
