REPORT ON FISHES. PART II : SISORIDAE AND CYPRINIDAE 347 



Tn the speciim-iis before me the length of the head is coiitainetl ahout 4.5 times or a 

 little over in the total length excluiling the caudal fin. The eyes are large and their diam- 

 eter is contained from 4.5 to nearly 5 times in the length of the head. The snout is short 

 and stump\- and 1.5 times longer than the orhit. The interorhital space is nearly 1.5 times 

 the orbital width. 1"he barbels are very shtjrt and not more than half as long as the diameter 

 of the eyes. The nmuth is somewhat narrow and horse-shoe-shaped. The lips are mod- 

 erately developed and more or less tough. In some specimens the lower jaw is provided 

 with a sharp margin. 



The dorsal fin is inserted slightly nearer the root of the caudal than the tip of the 

 snout ; its osseous spine is straight and fairly strong and has rather fine serrature on the 

 posterior Ixirder. In the smaller specimens the anal fin laid flat does not reach the root of 

 the caudal, whereas in the larger ones it almost reaches it. 



The colouration of the specimens in alcohol is reddish brown with a slightly darker 

 upper surface. The inner margin of the caudal fin is dusky. 



Bionomics: The air-bladder is of the normal Sclii.'^otliora.v-type. It appears that in 

 young specimens the posterior chamber is proportionately shorter than the anterior cham- 

 ber. In a specimen, 120 mm. long, the length of the anterior chamber is 15 mm., while 

 that of the posterior one is 20 mm. In a specimen, 178 mm. long, however, the correspond- 

 ing measurements are 25 mm. and 50 mm. The length of the intestine is almost 3 times 

 the length of the body excluding the caudal fin. The gut contents of 2 specimens (120, 

 178 mm.) were found to consist of fragments of some insect larvae mixed with a brownish 

 pulpy substance. 



Parasilrs: In the intestine of a specimen ( 178 mm. ) a few specimens of a species 

 of .\canthoeephalan worm were found. 



fh'.stribittidii: Sclii::i>thora.v curvifrons is one of the endemic species of the Kashmir 

 vallew It grows to a fairly large size, weighing about 31bs. and is known by the Kashmiri 

 fishermen as "Sattir."
