Length of head 4 to 6 in the total length. Eyes in the middle 

 or rather before the middle of the length of the head, diameter 5 

 to 6 in the length of head ; width of interorbital space in adults 

 almost flat, and nearly equal to one half length of head. A well- 

 developed lower lip, which has its posterior free edge straight or 

 convex. Barbels about one half as long as eye. Teeth pharyn- 

 geal, 4, 4, 2/2, 4, 4, crooked, pointed. Fins dorsal commencing 

 about midway between the snout and base of the caudal, its spine 

 moderately strong, toothed, becoming nearly smo>th in large 

 specimens, and as long as the head excluding the snout. Pectoral 

 four fifths as long as the head. Ventral not reaching anal, nor the 

 latter the caudal. Scales 24 rows between the lateral line and 

 base of the dorsal fin, and 19 between lateral line and ventral ; the 

 scales of the tile-like row equal two thirds of the diameter of the 

 eye in the young, and are as high as the diameter of orbit in adults. 

 Free portion of tbe tail as long as deep. Colour bluish along the 

 back, becoming silvery shot with gold on the sides and beneath. 

 Head likewise glossed with purple and gold. In some specimens 

 there are black spots on tbe sides and head.
