320 REPORT ON FISHES. PART I : COBITIDAE 



Tliejx5ny capsules of tlie air-bladder lie just Ijeneath the skin and are distinctly visible 

 Iruiii outside. 



The ground color of the spirit specimens is pale-brown, the dorsal surface lieing some- 

 what darker than the ventral. There are jiatches of dark culnur along the lateral line and 

 saddle-shaped l)anils along the dorsal surface. These colour markings are more pronounced 

 in the younger .specimens. The head is grayish above and pale-yellow Ixdow. The dorsal 

 fin is jirox'ided with 4-5 dark bands in the adult while in the smaller individuals there may 

 be only one or two bands. Ihe \entral and the anal iins are also siniilarb' niarketl. The 

 caudal fin is ])rovided with 3 broad Ijands, Init in young specimens only one broad, 

 prominent band is present in the middle of the fin. 



Localities: Several specimens in N. panguri were collected by the ^'ale North India 

 Expedition in August 1932 from the fLillowing localities: 



I'angur Tso. n;. 14.203 ft. (L74). Several )i)ung, half-grown an. 1 adult specimens. 

 Tso Nyak (L 71a). Several young, half-grown and adult specimens. 



Remarks: Nemachilus panguri seems to be a very close ally of N. deTerrai from 

 which it differs in i)r<i])ortions, esi)ccially of the eye and the dorsal fin. Though the differ- 

 ences do not seem to be markedly .specific, it is better to regard the two .species as distinct 

 in the present state of our knowledge of the fish fauna of Western Tiljet. 



Bionoiiiics: Like the two preceding species, N. panguri is also adapted to live in sta- 

 tionary waters where it can dart froni place to ])lace with the help of the whip-like caudal 

 peduncle or make vertical movements with the help of the large swim-bladder. The stomach 

 contents of a male specimen consisted of Chironomid larvae with their sandy and calcareous 

 cases. The alimentary canal is only slightly convolute; its length being seven-tenths of 

 the total length of the fish.
