Boulenger, Ann. & Mag. N. H. (7) x. 1902, p. 429. 



Depth of body three and a half to four times in the total length, length of head 

 four to four and a half times. Snout rounded, three to three and one-third times in 

 the length of the head ; diameter of eye four and a half to five and a half times in the 

 length of the head, interorbital width two and two-fifths to two and two-thirds times ; 

 mouth inferior, forming a broken arch, a feebly curved transverse line in front, its 

 width three to four times in the length of the head ; lips very feebly developed? 

 confined to the sides ; a thin horny sheath, with a blunt keel, covers the jaws ; barbels 

 two on each side, anterior a little shorter than the posterior, which is as long as or a 

 little shorter than the diameter of the eye, the distance between them measuring 

 three-fourths to once and one-third the diameter of the eye. Dorsal fin with IV 9-10 

 rays ; last simple ray very strong, bony, not serrated, as long as the head or only 

 two-thirds its length ; free edge of the fin strongly emarginate ; its distance from the 

 occiput less than its distance from the caudal fin. Anal fin with III 5 rays, its longest 

 ray three-fourths to once the length of the head, reaching or nearly reaching the root 

 of the caudal. Pectoral fin as long as or a little shorter than the head, not reaching 

 the ventral; latter a little posterior to origin of dorsal fin. Caudal fin deeply forked.
