Description of four species of Fishes from the Rivers at the 

 foot of the Boutan Mountains. By J. M'Clelland. 



Several species from the Boutan mountains have been 

 described in the notice of Mr. Griffith's collections, made 

 during the Embassy of Captain Pemberton, &c. in the se- 

 cond volume of this Journal, p. 586. 



Mr. A. Campbell, Superintendent of Darjeeling, favoured 

 me with two species from Darjeeling, noticed in the second 

 volume, p. 148. 



Mr. D. C. Russell, of the Bengal Civil Service, favoured 

 me with a species from the same quarter, which has been 

 noticed p. 427, vol. 1. 



It remains upon the present occasion to describe three 

 species subsequently received from Mr. A. Campbell, and 

 which would have been noticed earlier, but that I have been 

 waiting in hopes of receiving a regularly selected collection 

 from that quarter, such as might afford materials for a paper 

 on the subject of suitable interest and importance. 



Before going further, it is necessary in the first instance 

 to offer a few remarks on Mr. Russell's specimens, of the 

 Ground Fish of Boutan, or, as it has been called, inaccurate- 

 ly I suspect, the kmra Chang. This species belongs to the 

 same well known genus, with a small fish known in some 

 parts of Bengal under the native name Lata, in other places 

 called Chang. The Boutan ground fish is so much like the 

 Chang y that ordinary observers would only distinguish it as 

 considerably larger ; hence I conceive the term bura Chang 

 to be only a corruption of bura (large) Chang. In my 

 former remarks on the subject, the species was considered 

 to be the same as Ophicephalus barca, Buch. I now 

 consider it to be a distinct species, which may be named and 

 described as follows : —
