INDIAN CYPRINID^. 



Spec. Esox pajichax, Bucli. P. G. t. 3. f. 69. 



A black spot on the dorsal, opercula covered with scales, 

 D.6: P.16: V.6: A.14: C.16. 



Hab. Sunderbims in Bengal, where it attains two inches in 

 length. 



There is still a fourth species, t. 55. f. 4. which I derive from Buchanan's 

 collection of drawings, but cannot find it referred to in the Gangetic Fishes, 

 we must therefore postpone naming it until we see the papers of the late 

 Doctor, or the species itself. 



IV. Gen.— COBITIS. Lin. 



Char. Head and body elongated, little compressed, and no where depres- 

 sed ; the dorsal and ventral margins are little arched, and in some, almost 

 straight; the snout is long and directed obliquely downwards, and projects 

 slightly in front of a soft mouth, which is surrounded with short muscular 

 cirri; three rays in the branchial membrane. 



Obs. I sub-divide them into two sub-genera according to their general 

 structure and the form of the caudal fin.* 



* Since the remarks were made in a preceding part of this paper on IMr. Gray's sub-division 

 of the Loaches, I have been favoured with the perusal of a part of M. Agassiz's great work on 

 Fossil Fishes, in which I perceive the spined Loaclies are separated from the Linnsean genus as pro- 

 posed by Mr. Gray. Surely a principle of division must be unnatural that would separate 

 such species as Cob. oculata, t. 51. f. 1. and Cob. pavonacea, t. 52. f. 1.; and bring together sucli 

 species as Cob. dario, Buch. P. G. t. 29. f. 95. and Cob. cinnamoniea, t. 51. f. 5.—.^ : yet such would be 

 the effect of adopting ]\Ir. Gray's genus Botia, or what would be the same thing, IM. Agassiz's genus 

 Acanthopsis which differ only in name.
