420 INDIAN CYPRINIDZ. Sarcoborine: 
smooth abdomen of the two first species of this group presents to the 
narrow serrated abdominal ridge of the Clupeide. 
The stomach is equal to about half the entire length of the animal, and 
the intestine from the stomach to the vent only about half the length of the 
stomach itself, and separated from that organ, which it rivals in capacity, 
merely by a stricture. 
The liver and other large glands whose functions are supposed to 
facilitate digestion are extremely small in this species, though it is possessed 
of an insatiable carnivorous appetite; nor have I found in Cyprinide, in 
general, those glands bear any proportion to the size of the stomach, or the 
nature of the food in different species. 
This species occurs in all parts of Assam, in the Kosi, the Jumna, the 
Ganges, and the Soane rivers; in which last Buchanan says it attains the size 
of a Herring, and is called Trout by the English, chiefly from the spots on the 
sides, and its fine flavor. For the latter I cannot answer; but as the species 
of this group are not much esteemed by the natives, I suspect it owes its 
imagined sweetness, in some degree, to its supposed resemblance to Trout. 
Notwithstanding the beauty of its appearance, its habits are such as to render 
it very objectionable in fish ponds.
