Length of head 3| to 4, of caudal fin 6, height of body 6 in the 

 total length. Eyes covered by skin which, however, forms a rather 

 free margin along their lower edges ; diameter 5| to 6 in the length 

 of head, 2 to 2^ diameters from the end of snout and 2 apart. 

 Greatest width of the head equal to its length behind the angle of 

 the mouth. Upper jaw the longer, the width of the mouth equal 

 to three^tenths of the length of the head. Upper surface of the 

 head and occipital process smooth, covered by skin. Occipital 

 process rather more than twice as long as wide at its base, it is 

 notched anteriorly to receive the V-shaped basal bone. Scapular 

 process short, the cubito-humeral one pointed, as long as the head 

 behind the middle of the eyes, or even a little longer, and rough- 

 ened in lines. Barbels the maxillary do not quite reach the poste- 

 rior end of the head, the mandibular pair extend a little further ; the 

 nasal are very short. Teeth in villiform or cardiforin rows in both 

 jaws ; the posterior rows in the lower jaw, commencing behind the 

 symphysis, with rounded crowns, their size augmenting laterally. 

 Those in the palate in two semi-elliptical patches of rounded ones, 

 which are almost continuous along the median line, the posterior 

 being much the largest. Fins dorsal spine of moderate strength, as 

 long as the head excluding the snout, and finely serrated posteriorly 

 in almost its entire extent ; length of the base of the adipose three 

 fourths of that of the rayed fin and nearly equal to the extent of the 

 interspace between the two fins. Pectoral spine stronger and a little 

 longer than that of the dorsal, denticulated on both edges, not 

 reaching so far as the ventral fin. Anal rays appear to be sometimes 

 deficient in number. Colour of a dull yellowish colour, with dark 

 or even black fins. 



A drawing and description of this species exists amongst 

 Sir W. Elliot's collection ; the locality is not given, but was probably 

 the Kistna ; the fish is termed " Ghogra."

Length of head 4|, of caudal fin 4^, height of body 6 in the total 

 length. Eyes covered by the skin, which, however, is a little 

 reflected along its lower edge, diameter 4 in the length of the head, 

 1| diameters from the end of snout, and 1 apart. The greatest
