334 REPORT ON FISHES. PART II: SISORIPAE ANI1 CYPRIMDAK 



In tlie single specimen be lore nic the snout is sparsely studded with fairly sharp, warty 

 tubercles. The eves are situated slij;htly nearer to the tip of the snout than to the posterior 

 margin of the operculum. The lower lip is tril'ibed: llie lateral li^bes are broad and llat, 

 while the central one is narrower and somewhat elongated. The dorsal spine is fairly strong 

 and sharply denticulated posteriorly; its length is equal tn the head behind the nostrils. 



The ground colouration of the specimen in alcohol is reddish brnwn with a darker 

 dorso-lateral surface. 



Pistrihiilion: Sclii::otlioro.v hihintiis is essentially confined to Afghanistan and is com- 

 mon in the Kunar or the Chitral river and in its tributaries in the ("hitral X'alley. Its occur- 

 rence in the Upper Indus is rejiorted here fur the tirst time. Hybrids Utween this sjiecies 

 and Orriinis siiniatiis occur in the Kashmir \alley (<•. ;'. ]). 349) lint d" nut necessarily indi- 

 cate that Ixith parent species are present in that region. The species is usually found in 

 rapid-flowing waters.

The species can Ix? readiU distinguished troni others by its narrow and liigli anal tin. 

 which when laid l)ack, extends to the root of the caudal fin (Text-figure 3) and also by its 

 .sharp lower jaw. The body is somewhat narrow and cylindrical with a moderately com- 

 pressed caudal peduncle. The contour of the body as well as the development and structure 

 ">{ the tins highl}' suggest that the fish is an inhabitant of the rapid-running stream-, and 

 rivers. 



The N ale North India I'.xpcdition obtainetl a single gravid female in April, 1932, from 

 the follow ing locality : 



Channel : :Manasbal Lake ( Sta. K 48) ; 5,196 ft (3(K)nini.) 



The mouth is inferior, horse-shoe-sha])ed and \erv slighlK ol)lii|uc; it is nnich broader 

 than long and its .gape is almost ecpial to the length of the head in front of the nostrils. 

 The upper jaw is longer than the lower and is ])rovided with a fairly developed and partly 

 protrusible fleshy lip: the lower jaw has a free and sharp margin, practically denuded of 

 a true lip. The lower lip seems to have undergone atrojihy Inith in its structure and func- 

 tion, and is represented only laterally as two short and thin loose l],i])s (Text-figure 4). 



The osseous ray of the dorsal fin is moderately strong and almost as long as the head 

 behind the nostrils; its posterior serrations are fine and close-set. The length of the head 

 is cont.ained nearly 4.25 times in the length of the body without the caudal. The diameter 

 of the eye is contained 5.5 times in the length of the head. The interorbital space is flat 

 and wide and more than twice the orbital width. 'Jhe snout is broadly rounded anteriorlv 

 and almost twice as long as the diameter of the eve. 



The colouration of the specimen in alcohol is reddish brown with a somewhat darker 

 dorsal surface. All the tins are ti|)i)ed with black.
