 comparatively long, equalling- the length of the head Ijehind the nostrils, 

 (iii ) In the majority of full-grown individuals, irrespective of sex, the anal fin laid flat 

 is widely separated from the root of the caudal, while invariably in young and 

 half-grown specimens it just misses or only exceptionally it reaches the root of 

 the caudal.

FinuRF. 6. Lateral views of anterior parts of body of three specimens of Schicolhorax rsocinus Heckel 

 sliowing different forms of anal and candal fins. (a) Day's original specimen of "Schholluira.v pnnctaliis" 

 from Wular Lake (anal widely separated from caudal). X H- 0') Day's original specimen of "Schizolhorax 

 esocimis" from Leh (anal almost reaching caudal). X H- ('') A young specimen, 115mm. long (Kashmir 

 Survey coll.), from Jhelum River, Kashmir valley (anal reaching caudal). X 1'4. The arrow indicates the extent 

 of the anal tin in relation to the root of the caudal. 



From the foregoing account it is, T believe, abundantly clear that specific differentiation 

 between A", rsocinus and S. pimctatiis is impossible and that Day's .S". pimctatiis is only an 

 .aberrant \ariation t)f .S\ csdciiius Heckel. 



Hiniidiiilcs: The ])eritiinetuii is bhick. The length of the intestine is approximately 1.5 

 times the length of the body excluding the caudal fin. In adult individuals the length of 

 the anterior chaml>er of the air-])ladder, in propnrtion to that of the posterior chamber, is 

 ciiuipjiratively linger than it is in yinnig specimens. In a sjiecimen, 270 mm. long, the 

 leiiglb (il the anterior ch.'imber is 33 mm. and that of the posterior chamber fiO mm., while 

 in a specimen about 105 mm. long, the corresponding measurements are 16 mm. and 22 mm. 

 The gut contents of several .specimens from the Jhelum I'iiver and other localities in Srinagar 

 were ex;nnined. In some cases the iiilesline was pr;icticall\' empty, whereas in idbers frag-
