REPORT ON FISHES. PART i: COBITIDAE 317 



The above measurements are of the bladder after its removal from the Ixmy capsules. 



The bony capsules are incomplete in the part where they touch the skin so that their 

 position can be readily made out from the external surface. 



In spirit specimens the general colour of the body is pale-olivaceous. A series of fairly 

 broad blotches is present along the lateral line and in some specimens they unite to form 

 a longitudinal band. Along the dorsal surface, especially in the tail region, there are a 

 number of saddle-shaped bands. The dorsal surface and the sides are further irrorated with 

 small black dots. The dorsal and the caudal fins are provided with two to three broad bands. 

 The anal and the ventral fins are provided with one or two I)ands each. 



Localities: In all six specimens were collected by the Yale North India Expedition 

 during June 1932 from the following localities : 



About 3 miles west of Mugleb, ca. 13,525 ft. (L3S). 1 specimen (young). 

 Pond between Durlnik and Tangtse, ca. 13,000 ft. (L36). 3 specimens (S ). 

 Tsar Tso, ca. 13,950 ft. (L39). 1 specimen (young). 

 Pool isolated from the river at Lukung, ca. 14,164 ft. (L40). 1 specimen ( 9 ). 



It is seen from the alxjve that the species occurs in pools, and small lakes. 



Bioiioiiiics: The species is adapted for life in stationary waters of lakes where its well 

 developed air-liladder enal)les it to swim about freely at different depths. It feeds on insect 

 larvae and pupae that encrust rocks and stones. Its horizontal, paired fins enable it to adhere 

 to rocks and its lower jaw appears to lae capable of acting as a shovel for rasping off 

 encrusting organisms. The alimentary canal is a simple tube without many convi)lutioiis 

 and its length is about three-fifths of the total length. The eggs are small and the o\'aries 

 extend right up U> the anterior end of the abdominal cavity.
