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, Gonorhijnclms 

 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
