low. They are situated nearer to the tip of the snout than to the 

 posterior margin of the opeiculum ; their diameter is contained 

 from 4"6 to 5'7 times in the length of the head, 2-2"i times in the 

 length of the snout and 2-i-2"6 times in the interorbital width. 

 There are two pairs of barbels, longer than the diameter of the 

 eye. The snout is smooth and the nostrils are situated nearer the 

 margin of the orbit than to the tip of the snout. The mouth- 

 opening is somewhat arched and is situated slightly behind the tip 

 of the snout. The mental disc exhibits considerable variation in 

 the three adult specimens examined. In the ripe female it corres- 

 ponds to developmental stage 4 and consists of a rectangular 

 pad behind the mouth which is separated by a faint line of de- 

 marcation into an anterior portion, the posterior labial fold, and

the posterior portion, the disc proper. In the other two male 

 specimens it is more marked, but the true lips are still visible and 

 the various components of the disc are not well differentiated. The 

 origin of the dorsal fin is slightly nearer to the tip of the snout 

 than to the base of the caudal fin and its longest ray is as high as 

 the depth of the body below it. The pectorals are shorter than 

 the length of the head and are separated from the ventrals by a 

 considerable distance. 



In spirit the specimens have lost their natural colouration. 

 They are dusky on the body above the lateral line and on the upper 

 surface of the head. The rest is dirty white and the cheeks are 

 whitish. 



The air-bladder is of the normal Cyprinid type ; its length is 

 contained 2'8 times in the length of the fish without the caudal fin. 



The scales are poorly developed on the under surface and are
