This species is readily recognised by its flat or slightly con- 

 cave head and by the presence of a large number of prominent 

 tubercular areas on the otherwise smooth snout. 



Rao described Garra platycephala from young specimens in 

 which the tubercular area-, are not raised and the snout, though 

 marked by a large number of mucous pores, is uniformly flat- 

 tened. 



The air-bladder is much reduced ; the following are its

The tish is almost subcylindrical with the head and body 

 shghtly depressed. The dorsal profile rises considerably from the 

 tip of the snout to the base of the dorsal fin beyond which it 

 gradually slopes to the base of the caudal fin. The ventral pro- 

 file is straight throughout. The length of the head is contained 

 4"5 times and the depth of the body 4*5 to 5 times m the length of 

 the fish without the caudal fin. The head is i'2 times as long as 

 wide. The eyes are laterally placed, slightly below the dorsal pro- 

 file of the head, and are invisible from below ; the diameter is con- 

 tained 5'2 times in the length of the head and about 2'5 times in 

 the length of the snout and in the interorbital width. The mouth;
