INDIAN CYPRINID^. 313 



Fig. 4. Oreinus iwogastus, 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. 



nmidina, 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 

 Siluridce and Pikes, with which all the waters in the interior abound. 



Fig. 2. Ctjp. 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. Barhus hexagonolepis, J. M. BoJear 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.
