Of this species 1 have examined six specimens; three are 

 females and in the remaining three I have not been able to deter- 

 mine the sex, 



There is a well-marked trilobed proboscis on the snout. The 

 lateral lobes are free and tapering while the median lobe is 

 represented by an immoveable rectangular prominence. The 

 nostrils are situated near the bases of the former and are covered 

 over by them. 



The air-bladder is reduced, but its form is of the normal 

 Cyprinid type. The following are the dimensions of the air- 

 bladder in a specimen 9-7 cm. in length : —
