INDIAN CYPRINIDiE. 451 



I am indebted to the gracious consideration of the Right Honor- 

 able George, Lord Auckland, G. C. B. dec. not only for the opportunity 

 of examining my collections of fishes, which had otherwise been denied on 

 my return from Assam, but also for the inspection of the splendid collec- 

 tion of drawings of the late Dr. Francis Buchanan Hamilton, many of 

 which, under Providence, I have been the humble means of submitting to 

 the world. 



SUPPLEMENT. 



Since this paper was presented, two important communications have 

 been made in Europe on the subject of the Fresh- water Fishes of India. The 

 first is a paper presented in December, 1838, to the Zoological Society of 

 London by Colonel Sykes, descriptive of forty species inhabiting the 

 rivers of the Deckan, including several new genera. As Colonel Sykes's 

 paper has not yet appeared, it remains to be seen how far the fishes 

 of Western India correspond with those of the Ganges, Bramaputra, and 

 North-eastern tributaries of those rivers, from which nearly all Bucha- 

 nan's species and my own have been derived. The second work just al- 

 luded to, embraces descriptions of sixteen species of fishes found by Baron 

 Hiigel near the source of the northern branches of the Indus, of which fifteen 

 belong to the great natural family CyprinidcB ; these are all ably described 

 and beautifully illustrated by M. von Heckel, an eminent German naturalist 

 of Vienna,* who anticipates some of the observations contained in the fore- 

 going pages, as well as one new genus, Oreinns, of which INI. v. Heckel 

 describes ten species, all except one distinct from the three which I have 

 met with. The curious circumstance of the absence of Sahnoiudie in
