THE ANIMALS OF ARCTIC AMERICA AND CANADA 



In the old World the species is represented by the Kamchatkan bighorn 

 (0. canadensis nivicola) of Kamchatka and Clifton's bighorn (0. c. borealis) of 

 north-eastern Siberia, which are closely allied to the Alaskan sheep, although 

 dark-coloured. It should be added that the Mexican and Sonoran big-horns form 

 other local races of this variable and wide-spread species, distinguished by their 

 unusually large ears. Inclusive of the above variations, the bighorn ranges in 

 America from Mexico in the south to Alaska in the north, and from the valleys 

 of the Missouri and Yellowstone to the Pacific, though in many localities within 

 these limits it has never been known.

White Goat. 



With the white or Rocky Mountain goat (Oreamnus americanus), 

 we come to an exclusively North American type of hollow-horned 

 ruminant, of which four local races have been named. The range of this animal 

 extends from about latitude 36° in California to Alaska, British Columbia being 

 perhaps the country in which it is most common. Probably the white goat is 

 related to the Asiatic serows rather than to the true wild goats. It has pointed 

 ears, and black horns from 6 to 10 inches long which curve slightly backwards 

 and are ringed to about half-way up and smooth towards the tips. In size it is 

 about the equal of ordinary sheep, but with the shoulders much elevated. The 

 body is covered with long hair, nearly straight and pendent on the sides and
