GENUS BARILIUS. 
Geographical Distribution. Tliis genus is found 
on the Continent of India and the East of Africa, 
including the River Nile.

Mouth wide, opening forwards, Barbels 4, or 2, or 
none. 
We can divide the species, for convenience, into 
three groups, according to the number, or want, of 
barbels. It is not however a natural division, as fre- 
quently the barbels are so small as to be hardly per- 
ceptible — or wanting, in species that would normally 
possess them. 
Where not otherwise mentioned, the rays of the 
dorsal fin, are 9 or 10, those of the anal fin about 
12, and the number of scales along the body about 43. 
A. Species with four Barbels.

This is one of the smallest of Indian fishes, it is 
easily recognised by the indigo-blne bands running 
the whole length of the body, extending over the 
caudal and anal fins.
