Snout obtusely conical, projecting beyond the mouth, the cleft 

 of the mouth extends beyond the middle of the eye. The teeth 

 of the outer series are visibly stronger than the remainder. Barbel 

 nearly as long as the eye. The interorbital space is flat, its width 

 being much less than the diameter of the eye, which is compara- 

 tively small. The scales are provided with five ridges, each ridge 

 composed of several spines, the central ridge being the strongest. 

 There are eight scales in a transverse series between the first 

 dorsal and the lateral line. Lower limb of the prseoperculum 

 scaleless. Second dorsal spine armed with barbs in front, which 

 are rather distantly set. The second dorsal fin commences at a 

 distance from the first, which is less than the length of the head.

 the snout ; dorsal and anal rays simple. Scales of moderate size ;
