586 EXTINCT AND VANISHING MAMMALS 



Kurtka and Chatir-kul; but from the eastern sources of the Atpash down as 

 far as the Chatir-kul it is only found in company with O. Polii [=: O. a. humei]. 



Severtzoff adds some remarks on the distribution of sheep on 

 the Russian side of the Dzungarian Alatau, a territory now included 

 in the range of 0. a. littledalei. 



Nazaroff's notes (1932), referring to the period about 1919-20, 

 furnish some of the latest information we have concerning this 

 sheep. "Here [in the ravine of Kegats, somewhere near Issyk Kul] 

 there are quantities of wild sheep (arkhar, Ov is karelini) , which go 

 about in large flocks" (p. 179) . "In Kok Mainak [near the western 

 end of Issyk Kul] wild sheep and ibex come down from the moun- 

 tains in the early morning to water in the Chu" (p. 221) . "There are 

 lots of arkhars in this district [near the station of Sary Bulak, 

 southwest of Issyk Kul]" (p. 232). 



In 1925 T. and K. Roosevelt (1926, pp. 132-145) found consider- 

 able numbers of sheep in the Kooksu district of the Tian Shan, 

 southwest of the Yulduz. They refer to them as karelini, but the 

 specimen figured on the plate facing page 152 does not appear to be 

 altogether typical of that subspecies; it is perhaps an intergrade 

 between two or three subspecies. Its horns measured 61 inches. 



[Ovis heinsii Severtzov (Izviestia Imper. Obshchestvo Liub. 

 Estest., Antrop. i Etnogr. [Moscow], vol. 8, pt. 2, pp. 84, 87, 

 1873), was based upon subadult skulls found in the Tokmak dis- 

 trict, about 100 miles west of Issyk-kul, Russian Turkestan. It 

 does not seem to be very clearly differentiated from 0. a. karelini. 

 Tokmak is situated in the valley of the Chu River, and the moun- 

 tains both to the north and to the south are inhabited, according 

 to Nasonov (1923, pp. 73-74), by karelini. This author (p. 90) 

 considers it quite possible that, owing to the increase in the number 

 of villages in the Tokmak district, heinsii has become extinct. 

 W. G. Heptner (in litt., December, 1936) expresses the same 

 opinion.]
