Psilorhynchus. INDIAN CYPRINID&. 429 
Now the Stolephore or Engraulis, Cuv. (Anchovies) belong to the Clu- 
peide, to which the depressed form, and short anals of these species render it 
impossible that they could belong; and Buchanan seems afterwards to have 
corrected the mistake, as the species in question appear to me to be described 
in the Gangetic Fishes as Cyprinus sucatio, Buch. and Cyprinus balitora, id. 
The typical character of these species depends on the extreme prolongation 
of the snout in front of a remarkably small soft mouth, which is without cirri. 
The defenceless body, the backward position of the eyes, the well formed 
and fully developed fins, indicative of rapid powers of motion, are also analo- 
gical relations to the suctorial types of other classes. We are not acquainted 
with the habits of the species in question, and can only say that they were 
obtained in the north-eastern parts of Bengal, to which they have been pro- 
bably swept down from the mountains.*

Said to have a strong resemblance to many of the genus Cobztis both in form 
and colour, but wants cirri. 
* Since the characters of these interesting species noted in the synopsis were printed, together 
with other remarks regarding the singular forms of the two species figured by Buchanan, I have 
been fortunate enough to find a single specimen of one of them in a small collection of fishes with 
which I have been favoured from Upper Assam by Capt. Hannay.
