Four longitudinal series of scales between the lateral line and 

 ventral fin. Snout -with pores or tubercles in front, the three 

 largest being placed in a transverse series (• . •), and the central 

 being the largest; there are sometimes other smaller pores sur- 

 rounding the larger ones. Barbels moderately developed, about as 

 long as the eye, which occupies nearly the middle of the length of 

 the head. The height of the body is contained thrice and one- 

 fourth in the total length (without caudal), the length of the head 

 five times. Generally a dark band along the lateral line.
