mouth which is small, transverse, and opened horizontally by the muscles of 
the snout; the anterior lip is fimbriated, the posterior, hard and cartilaginous. 
In this species there is no disk behind the mouth. Thirty-seven scales are 
ranged along the lateral line, and nine rows across the body from the base of 
the ventrals to the dorsum; colour green above, below silvery. The fin 
rays are,

The alimentary canal is eight lengths of the body including the head 
and caudal, of considerable diameter or capacity, and loaded at all times from 
the throat to the vent with a green vegetable matter. The liver was not 
observed in many of the specimens examined; in others, small hepatic glands 
seemed to be dispersed throughout the folds of the intestines, as in many of 
the Gudgeons: and in such as present this peculiar form of liver, the whole 
of the abdominal viscera float in a dark oily kind of fluid. 
The nature and source of this secretion in most of the Gudgeons and 
Gonorhynchs will require to be farther inquired into. I have found it in those 
species in which the liver is normal, as well as in those in which that organ 
seemed to be represented by small detached glands. I have also observed that 
either this fluid, or the great proportion of vegetable matter contained in the 
intestines of the Gudgeons and Gonorhynchs, tends rapidly to putrefac- 
tion ; to which cause, as well as to the neglect of removing the viscera from 
these species immediately after they are caught, I ascribe the bad effects which 
have by some been observed to result on certain occasions from their use. Dr. 
Campbell, of Nipal, describes a case in one of Corbyn’s Journals in which 
deleterious effects were produced by a common fish in the streams at Katman- 
du, which he supposed to be identical with a Kemaon species, Gonorhynchus 
petrophilus. Mr. Bruce, of Assam, also mentioned to me, that he knew of 
instances of indisposition supposed to be occasioned by a variety of Bangon. 
All Bangons and Gonorhynchs should therefore have the viscera removed 
soon after they are taken, and the dark oily fluid washed away ; when, if it be
