posterior to the vertical from the last dorsal ray. Caudal pointed, 

 upper lobe the longer. Colour leaden superiorly, becoming yel- 

 lowish along the abdomen and cheeks. Maxillary barbels, dorsal 

 and caudal fins dusky ; pectoral, ventral, and anal dull white. 

 There is usually a black spot covering the basal bone of the dorsal 

 fin. Occasionally there is a bluish band along the lateral line.

 Length of head 4g, of caudal fin 4g, height of body 4g in the total 

 length. Eyes diameter 3| in the length of the head, | to 1 diameter 

 from the end of snout, and 1^ apart. Greatest width of the head 

 equal to its length excluding the snout. Gape of mouth equal to 

 two fifths of the length of the head. Upper jaw slightly the 

 longer. Median longitudinal groove extending to the base of the 

 occipital process, which latter (as well as the upper surface of the 

 head) is corrugated and about thrice as long as it is wide at its 

 base, it reaches the basal bone of the dorsal fin. .Barbels the 

 nasal are nearly as long as the head, the maxillary reach the base 

 of the ventral, the external mandibular the base of the pectoral, 

 while the internal are shorter. Teeth in a narrow uninterrupted 

 band across the palate. Fins dorsal spine as long as the head 

 excluding the snout, slightly serrated anteriorly in its upper third, 

 and posteriorly in its whole extent ; the length of the base of the 

 adipose dorsal one third less than that of the rayed fin, and equal 

 to one half the length of the interspace between the two fins ; in 

 some specimens it is much longer. Pectoral spine nearly as long 

 as the head, stronger than that of the dorsal, smooth externally, and 

 with about 13 denticulations internally. Ventrals arising on a 

 vertical line just behind the last dorsal ray. Caudal forked, upper 

 lobe the longer. Colour brilliant yellow, with a black shoulder- 

 spot and about five black longitudinal lines. In some specimens 

 the mandibular barbels are white with a black streak. 



Hab. Northern India, the Punjab and Assam ; attaining 3 to 4 

 inches in length.
