The American Bighorn. 



Distrihution. — 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 

 P. Z. S., 1885, p. 675. and Biddulph /. c.)

 and possibly to Shiraz (Blanford) ; Astrabad in Northern Persia 

 (Beresford Lovett) ; this sheep is generally found at lower eleva- 

 tions than the other wild sheep and in places where the heat is very 

 excessive in summer.
