INDIAN CYPRINIDZ. 451 
I am indebted to the gracious consideration of the Rigur Honor- 
ABLE GrEorGE, Lorp AvcCKLAND, G. C. B. &c. 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 Cyprinide ; 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, Oreinus, of which M. v. Heckel 
describes ten species, all except one distinct from the three which I have 
met with. The curious circumstance of the absence of Salmonide in
