MB. R. LYDEKKEB ON AN ASIATIC IBEX. 



("Feb. 20, 



p. 185, 1898). The skin of this ram was of a greyish-brown 

 colour above, with a light saddle-shaped patch on the back, a 

 white caudal disk, which did not include the tail, and the legs 

 below the knees and hocks pure white, as were the under-parts. 

 Above the caudal disk was a dark brown band ; the shoulders and 

 thighs were as dark as the back ; and on the nape of the neck was 

 a tuft of very long slate-coloured hair, which was dark brown at 

 the roots. This tuft was also present in a female skin : a much 



Male of Littledale's Sheep (Ovis satrevsis), in winter coat. 



shorter one occurred in a female head of 0. amnion, but it was 

 absent in 0. poli. From the latter in winter dress the present 

 specimens also differed by the dark shoulders and thighs. The 

 development of a white caudal disk in the winter coat alone was 

 another peculiarity of 0. sairensis. The specimens were said to 

 have been obtained in the Irtish valley, which drains the Semi- 

 palatinsk Altai. 



In this connection Mr. Lydekker desired to call attention to 

 an error in his work entitled ' Wild Oxen, Sheep and Groats of 

 All Lands,' where it was stated that the face and lower part of 

 the legs of 0. amnion were always white, whereas they were so 

 only in the typical race during summer, and then might be better 

 described as dirty white. 



Mr. Lydekker likewise exhibited the skulls, horns, and skins of 

 a male and female Ibex obtained with the preceding specimens 

 which he thought might possibly belong to Capratibirica dauvergnei. 

 In the ram the general colour of^the fur was light brown, with a
