3 times in the length of the head and the snout is i'5 times the 

 diameter of the eye in length. The interorbital width is greater 

 than the diameter of the eye. The mouth is situated on the under 

 surface of the head considerably behind the tip of the snout and is 

 bordered by thick lips. The lower lip and the skin immediately 

 behind it is somewhat papillated. There are two curved grooves 

 running from the angle of the mouth to the tip of the snout. 

 The nostrils are situated considerably nearer to the eye than to 

 the tip of the snout. 



The dorsal fin commences in advance of the ventrals, and its 

 origin is much nearer to the tip of the snout than to the base 

 of the caudal fin ; its free margin is truncate and oblique. The 

 longest ray of the dorsal fin is considerably higher than the depth 

 of the body below it ; its shortest ray equals the longest raj' of the 

 anal fin in length. There are two spines and 7 or 8 branched rays 

 in the dorsal fin. The pectoral fins are greatly' expanded and are 

 liorizontally placed. They contain 13 or 14 rays, of which the first 

 four are not branched. It is separated from the base of the ventral 

 fins by half its own length. The ventrals are only slightly shorter 

 than the pectorals; they are expanded and horizontally placed. 

 They contain 9 or 10 rays, of which the first two are not branched. 

 The ventrals extend considerably beyond the anal opening. The 

 anal fin is short and rounded and is placed nearer to the base of the 

 caudal than to that of the ventral fin. It contains seven rays, 

 of which five are branched. The caudal fin is as long as the length 

 of the head and is deeply forked. Both the lobes are pointed; 

 the upper is slightly longer than the lower. 



The lepidosis is quite normal except on the chest, where the 

 scales are either absent or greatly reduced. There are 38 scales 

 along the lateral line from the angle of the operculum to the base 

 of the caudal fin, and six series of longitudinal rows of scales 

 between the bases of the dorsal and the ventral fins. A scale from 

 near the base of the dorsal fin is semicircular in outline with an 

 almost flat base and an arched apex. The nucleus is eccentric 

 and is situated close to the base. There are about 5 or 6 radii to 

 the apex and the circular striae are inde6nite and closelj' packed 

 together. 



The air-bladder has undergone a certain amount of degenera- 

 tion from the normal cyprinid type. The anterior chamber is later- 

 ally flattened and covered with a thick fibrous coat. The posterior 

 chamber is narrow and elongated and is of uniform thickness 

 throushout ; its walls are greatly thickened. It is displaced from 

 its original position and comes to lie on one side of the anterior 

 chamber. 



Hamilton Buchanan describes the colour of the species as 

 follows: " Above the colour is greenish, with scattered dots; 

 on the sides these are collected into clouds, and below the body is 

 whitish and diaphanous. The fins of the back, breast and tail, 

 are dotted. The eyes are brown, with a narrow golden circle 

 round the pupil." The specimens before me possess five broad,
