A well formed, handsome species, with a small head; jaws of equal 
length ; intermaxillaries protractile ; depth of the body equal to about one- 
third of its length ; the sides are silvery, and marked by a row of small oblong 
spots placed transversely ; the mouth is cleft to the eyes. Fin rays are,

Forty-two scales along the lateral line, and ten in each oblique row from 
the base of the ventrals to the dorsum. Brachial plates exposed behind the 
branchial aperture. Found by Buchanan in the Ganges at Patna. 
The rays of the caudal being so generally nineteen, I am in some doubt 
as to their being only sixteen in this species, as observed by Buchanan. 
In two small collections of fishes received from very opposite parts of 
India—Upper Assam and the heights on the Western side of Bengal, for which 
I have been indebted to the kindness of Captain Hannay and Dr. Macleod—I 
find a species which, with the exception of having the usual number of 
caudal rays, differs but slightly from the above. 
The following are its characters—forty-four scales along the lateral line, 
and eleven from the base of the ventrals to the dorsum, nine bars or trans- 
verse spots on the back.
