Depth of body three and one-third times in the total length, length of head three 

 and two-thirds times. Snout rounded, three and one-third times in the length of the 

 head ; diameter of eye six and a half times in the length of the head, interorbital 

 width two and a half times ; mouth inferior, its width four times in the length of the 

 head ; lips moderate, interrupted on the chin ; barbels two on each side, subequal, 

 a little shorter than the eye. Dorsal fin with III 9 rays, last simple ray very strong, 

 bony, not serrated, straight, half the length of the head ; free edge of the fin 

 slightly emarginate ; its distance from the occiput a little greater than its distance 

 from the caudal fin. Anal fin with III 5 rays, the longest three-fifths length of 

 head. Pectoral fin acutely pointed, three-fourths the length of the head, nearly 

 reaching the ventral. Latter in advance of the origin of the dorsal. Caudal fin 

 deeply forked. Caudal peduncle once and three-fifths as long as deep. Scales longi- 

 tudinally striated, 35 gf, 3 between lateral line and ventral, 12 round caudal peduncle.
