WILD SHEEP OF ASIA AND AMERICA 275 



under the name of O. ammon storcki. In its small 

 size it is analogous to the Bokharan argali, the 

 most western representative of the species ; this 

 diminution in corporeal bulk at the two extremities 

 of the range of the species being a feature which 

 might naturally be expected to occur. 



The next representative of the species is the 

 Saiar argali {O. a. sairensis), from the Saiar or Jair 

 Mountains of Zungaria, which has small but rela- 

 tively massive horns, usually measuring about 45^ 

 to 47 inches in length, with a girth of from 14I 

 to 15 J inches. This sheep serves in some degree 

 to connect the typical Altai argali with the Pamir 

 race of the species, the horns being more open 

 than in ammon, but less so than in any of the 

 following races ; they are also less finely wrinkled 

 than in ammon. From both ammon and poli the 

 Saiar argali differs by the upper part of the face 

 being brown and the muzzle white. 



In the year 1873 the Russian naturalist Severt- 

 zow gave the name Ovis karelini to a wild sheep 

 from the Alatau Mountains of the Semirechensk 

 Altai, immediately north of Lake Issik (Issik Kul). 

 With this race Messrs. V. and B. Brooke^ sub- 

 sequently identified the wild sheep brought home 

 by the Yarkand Expedition in 1873 from the western 

 end of the Tian Shan to the north-west of Kashgar ; 

 and this identification was followed by Dr. W. T. 

 ' Proc. Zool. Soc, 1875, P- S'2.
