D. 10. A. 8. L. lat. .31. L. transv. t 



The osseous dorsal ray is of moderate strength, finely serrated, 

 and but little shorter than the head. There are two and a half 

 longitudinal series of scales between the lateral line and the root of 

 the ventral fin. Body compressed, its depth being equal to the 

 length of the head and one fourth of the total length (without 

 caudal). The diameter of the eye equals the length of the snout 

 and is one fourth of the length of the head. The upper barbel is 

 shorter than the lower, which is as long as the eye. Jaws of equal 

 length. Interorbital space convex, wider than the eye. Dorsal 

 fin about as high as the body, its origin being somewhat in advance 

 of that of the ventral and equidistant from the end of the snout 

 and from the root of the caudal. Fork of the caudal of moderate 

 depth. Silvery, with a bluish band along the middle of the side, 

 the band terminating in a small black spot on the root of the 

 caudal fin. 



I take this opportunity of describing this species here from two 

 specimens which were collected at Teita by Mr. "Wray, and of 

 which the larger is only 3 inches long.
