74 Records of the Indian Museum. [Voi.. VI, 



some specimens from the Chumbi valley and I myself had found 

 this species in considerable numbers in the neighbourhood of 

 Gyantse in 1906-1907. 



The following is a list of the localities with their altitudes : — 



(i) Ling-ma- tang , Chumbi valley, 11,500 feet. In the 

 Ammo-chu, a tributary of the Raidak. At this point 

 the river traverses a sedgy plain. Its breadth is 

 roughly to — 15 yards. The fish can be seen in consi- 

 derable numbers. 



(2) Phari, at the head of the Chumbi valley, eight miles S. 



of the watershed, 14,300 feet. In a small tributary of 

 the Ammo-chu. 



(3) Guru, 25 miles N. of the watershed, 15,000 feet. In a 



hill stream which disappears into the ground. 



[The streams in the latter two localities are small rivulets 

 running off the face of barren stony mountains, but ending in 

 broad and marshy plains. They are frozen for at least six months 

 of the year, but nevertheless both animal and vegetable life is 

 remarkabl}^ abundant. It should be noticed that migration of 

 fish from the third locality is out of the question. Not only 

 do a number of the smaller streams end by disappearing in the 

 ground, but the only river flowing out of the Rham Tso ends in the 

 Kala Tso, 14,600 feet above the sea, from which there is no visible 

 outflow. The aquatic population of this area is therefore unable 

 at any time of the year to descend lower than 14,600 feet.] 



(4) Kang-ma, 30 miles S. of Gyantse, 13,900 feet. In the 



N3"ang-chu. 



(5) Gyantse, 13,100 feet. In the N5^ang-chu and its tribu- 



taries. 



2. I was fortunate in being able to compare this collection 

 with two other collections of Schizopygopsis from Central Asia 

 which are stored in the Indian Museum. The first is that which 

 Dr. Stoliczka obtained during Sir Douglas Forsyth's Mission to 

 Yarkand in 1873-74. The second consists of the specimens of S. 

 severzovi, Herz., which Dr. Alcock collected while serving with the 

 Pamir Boundary Commission of 1895. 



3. The measurements of the individual fish of these two spe- 

 cies ^ in the collection of the Imperial Academy of Science in St. 

 Petersburgh, are also available in the report by Dr. Herzen- 

 stein (4). 



4. Stoliczka found the fish which was afterwards honoured 

 with his name in the headwaters of the Indus in the neighbour- 

 hood of Leh in Ladakh, at an elevation of 11,500 feet above sea 

 level, of the Oxus (Aktash, 12,880 feet, Upper Kora-Kul and 

 Pan] ah) and of the Yarkand river at Sarikol. 



Day {2, p. 9) doubts the accuracy of this latter record; " I 

 am very dubious of these specimens, and hardly think that they 

 can have been obtained from waters that flow into the Yarkand
