The general form and proportions of this species agree veiy nearly with 

 those of Gohio isiirus, but in structure it differs essentially from that species. The 

 snout is depressed, smooth, long, soft, and rather pointed ; with a few mucous 

 pores, which however cause little or no roughness. The mouth is small and 

 semicircular, and placed horizontally on the lower surface of the head, which 

 is equal to a third length of the body, exclusive of the head and caudal. The 

 eyes are placed on a prominent ridge intermediate between the snout and the 

 branchial aperture. The depth of the body is equal to half the length, ex- 

 clusive of the head and caudal ; the fins are feeble, the pectorals and ventrals 

 about equal in size, and the upper lobe of the caudal is rather longer than the 

 lower; the upper part of the body from the lateral line to the dorsum is a 

 dark blue, the lower parts are white. The fin rays are, 



: P.17 : V.9 : A.7 : C.12. 



There are forty-two scales along the lateral line, and thirteen in an oblique 

 row from the base of the ventrals to the dorsum ; the scales are short, and 

 their exposed surfaces are rhomboidal as usual. The alimentary canal is equal 

 to eleven lengths of the body inclusive of the head and caudal ; and as in 

 the last two species, the liver consists of numerous detached glands dispersed 

 throughout the abdomen. 



This species was found by Mr. Griffith (to whom I am indebted for the 

 only specimen I have seen) to inhabit the higher parts of the Bramaputra, 

 where the river becomes rapid and clear, and the bottom composed of boulders.

This is a small species of which I have only seen one individual, which 

 was found by Mr. Griffith in the higher parts of the Bramaputra.
