Herzenstein {op. cit.) has recognised several varieties of this 

 species, most of which so far as T can judge from the figures 

 represent different species. My specimens agree with the typical 

 form , of which I have examined one specimen from Rupshu. 



Vinciguerra ' has recorded the species from Skardu, but it 

 appears from his description that he has grouped several distinct 

 forms under one name. In identifying his specimens as N. 

 stoliczkae he has followed Day and Herzenstein for he observes 

 that, " questa determinazione e basata non tanto sulla des- 

 crizione e figura originate, quanto su quelle di Day, di Giinther e 

 specialmente di Herzenstein." 



Lloyd * referred some specimens from Eastern Tibet to this 

 species. I have been able to recognize at least three different 

 forms among the material he examined, two of them belonging to 

 the genus Nemachilus, viz. N. lhasac Regan and N. tihetanus Regan , 6 

 while the third belongs to the genus Diplophysa and is described 

 here as new. 



Day * in his later works regarded Nemachilus t;riffithii t Giinther, 5 

 as synonymous with this species. I have not examined any speci- 

 men of Giinther 's species, but it appears from the description that 

 the two are different. In N. griffithii " the origin of the dorsal fin 

 is midway between the root of the caudal and the end of the snout," 

 while in N. stoliczkae "the origin ot the dorsal fin is conspicuously 

 nearer to the root of the caudal than to the end of the snout." 



Nemachilus tcnuicauda (Steind.).

 This species closely resembles N. stoliczkae, from which it is 

 distinguished by its elongate and narrow caudal peduncle and by 

 its colouration. 



Nemachilus tenuicauda is represented in our collection by two 

 specimens from Leh. 



Nemachilus marmoratus (Heckel).

This is apparently a rare species and is represented in our 

 collection by a few specimens recently obtained in Kashmir. The 

 specimens were obtained from Kukarnag Spring and from ponds 

 on the road between Martand and Ichabal.
