INDIAN CYPRINIDZ. 313 
Fig. 4. Oreinus progastus, J. M. Half size. A characteristic, but not well exe- 
cuted figure of a species said to be poisonous; it is very common in 
the rapids of the Bramaputra, where it is called Adoee by the natives 
of the neighbouring parts of Assam, to whom it is well known. 
PLATE XLI. 
Fig. 1. Cirrhinus macronotus, J. M. This is a large species, nearly allied to Cyp. 
nandina, Buch. P. G. t. 8. f. 84, and very common during the cold 
season in sandy streams in Assam, where it attains a great size and 
weight. It is a species that might be extensively propagated in ponds 
in all parts of India, and together with other herbivorous Cyprins 
might be rendered much more abundant by merely destroying the 
Siluride and Pikes, with which all the waters in the interior abound. 
Fig. 2. Cyp. rohita, Buch. Ruee of the natives; no less celebrated in India 
than the Carp in Europe. It is the fish described by Buchanan, 
though not the one he has figured as the Ruee, the principal differ- 
ence being in the form of the mouth. The various slight modifica- 
tions of form under which the Ruee appears, prove the extent to 
which this species must have, at one period, been propagated in 
India. It is one of the largest and most abundant fishes in all parts 
of the country. 
Fig. 3. Barbus hexagonolepis, J. M. Bokar of the Assamese; a large species 
very common. It is generally dark brownish on the back, bluish 
below, and on the opercula, and the scales and opercula are illu- 
minated with yellow.
