Length of head 2/7, height of body 1/3 of the total length. 



Eyes. Diameter 1/3 of length of head, 1 diameter from end of 

 snout and apart. 



Mouth small, extending half the dis tance to below the orbit. 

 No barbels. 



Fins. Dorsal with an osseous, entire and weak, ray : it com- 

 mences midway between the snout and the base of the caudal fin. 



Lateral line, incomplete, becoming lost opposite the posterior 

 extremity of the dorsal fin. 



Colours. Silvery, a black mark at the base of each dorsal ray. 



A number of fry up to 1 finches in length from the Tenas- 

 serim Provinces are in the museum ; what they would be, when 

 adults, it is difficult to determine, but probably (as the lateral line 

 is incomplete) they never would grow large fish.
