The American Bighorn. 



Distribution. — The American Bighorn is found along the whole 

 range of the Rocky Mountains on both the eastern and western 

 slopes, from 68° N. as far as Sonora about 31° N. ; it is also found 

 in all the lesser ranges along the Eastern Pacific coast from Alaska 

 to California. 



It seems probable that there are two species, or, at any rate, races 

 of bighorns ; the northern one much resembling O. nivicola, the 

 Kamschatkan wild sheep, and a southern one. (See Guillimard
