408 INDIAN CYPRINIDiE. Sarcoborince. 



Instead of a knob, the apex of the lower jaw is furnished with a sharp 

 recurved edge ; the length of the head to that of the body as one to three ; the 

 intestine and stomach form a canal nearly twice the length of the body. 



The usual size of this species is about four inches, it is very common in 

 ponds and rivers throughout Bengal. There is a small diaphinous variety 

 also very common in Assam, where both kinds are understood by the same 

 name by the natives— -3/o«/^, said to be derived from the name of an insect on 

 which they feed. In this last variety I found the fin rays to be, 



D.8 : P.16 : V.9 : A.6 : C.19. 



There is still a third kind, white and silvery like the preceding, with 

 small scales, but more translucent and slender ; it is called by the fishermen 

 Dorikana. I have named it Li. pellucidus, but have not obtained sufficient 

 information to notice it separately in this place ; its distinguishing characters 

 are noted in the synopsis. 



In the preceding species the anal is smaller than the dorsal, and the 

 mouth is directed slightly upwards ; but in the following the anal is as large, 

 or larger than the dorsal, and the mouth horizontal.

 Voy. Dans VInd. t. 15. f. 3. 



This species I have not met with, but it is figured in M. Jacquemont's 

 travels in India ; and though no description has yet appeared of it, I may add 

 the following note taken from the drawing, which may be sufficient to 

 characterise the species. It appears to have been found in the Jumna. 



Depth equal to about half the length, exclusive of the head and caudal,^ 

 snout and margin of the lower jaw perforated by numerous mucous pores ; 

 dorsal and anal contain about nine rays each.
