A TYPICAL HEAD (JF white KAM 



In 1884 E. W. Nelson first described a pure white species fif mountain sheep inhahiting 

 Alaska and northwestern Canada, naming it OtIs dalli. in honor of Prof. Wm. H. Dall, the 

 well-known scientist and Alaskan explorer. While the horns of this species are not as

 a giant river and banked on the western 

 side by the mountains of the Alaska 

 Range, the great cordillera of the Terri-

 stone in the semicircular swing of this 

 great upheaval.
