As is evident from the aljove list, the family Sisoridae is represented in the collection 

 by two genera and only two species, 7'/"., Glyptothorax kashniircnsis, and Glyptostcrnnm 

 reticulatuin. G. kasJimirensis is an endemic species in the Kashmir Valley and is a river 

 form mainly restricted to sluggish water. G. rcticulaluiii is essentially a torrential species 

 and is widely distributed in the liead-waters of the ])rincipal river systems in High Centra! 

 Asia and Eastern Turkestan, and, as is to \x expected, specimens of the species were obtained 

 by the Expedition only from the rapid streams in Indian Tibet. Of the two representatives 

 of the sub-family Cyprininae, vis., Labeo diplostomiis and Crossochiliis punjahensis, special 

 attention may l)e directed to the latter species which had hitherto been known from the 

 Punjab and Baluchistan. The present record of the fish from the Kashmir valley greatly 

 extends its range in the Western Himalayan territory. The subfamily Schizotlwracinae is 

 represented in the collection by six species of Scliizothorax and one species each of Oreimis, 

 Schizopygopsis, Diptyclius and Ptycliobarbus. It may l)e noted that of the eight species of 

 Schizotliorax descril)ed by Heckel {op. cit.) from tiie Kashmir basin, only five were obtained 

 by the Expedition; three of these (S. planifrons, S. uiicropogon and S. cnrvifrons) are 

 endemic in the valley. .S". hibiatiis is essentially an Afghanistan species and its occurrence 

 in the head waters of the Indus is reported here for the first time. Orciniis sinuatns, Schizo- 

 pygopsis stoliczkac, Diptychus inactilatus and Ptychobarbus conirostris were found in their 

 usual habitats and do not call for any special remarks. The two hybrid forms between 

 Schizolhorax and Orciniis are worthy of interest, but similar hybridisation among fishes in 

 nature, particularly at high altitudes in Central Asia, is by no means a rare phenomenon
