 DESCRIPTION AND DISTRIBUTION 



AS we have seen in the classification of bears, science 

 recognizes, besides the Rocky Mountain grizzly 

 (JJrsus Horribilis Ord) and the very distinct Barren 

 Ground grizzly (Ursus Richardsoni Mayne Reid), two 

 sub-species of the Rocky Mountain type the Sonora 

 grizzly (Ursus Horribilis Horriaus Baird) and the Nor- 

 ton Sound grizzly. 



Taken together, these animals range from the moun- 

 tains in southern Mexico, throughout the Sierras and the 

 Rockies, all the way to the Barren Grounds; but Ursus 

 Horribilis Ord, the true grizzly bear in the sense that it 

 was the species first recognized by science, has a more 

 wide-spread geographical distribution than any of the 

 others. While its type locality is, of course, Montana, 

 where it was first discovered, its proper range extends 

 from Wyoming and northern Utah, throughout the Rocky 

 Mountain chain, to Norton Sound, Alaska; and neither in 

 Montana, Idaho, Wyoming, nor in the interior of British 

 Columbia south of the Barren Grounds, is any other 

 species to be encountered. On the other hand Horribilis^ 

 Ord wanders, to a considerable extent, into the domains 

 of other grizzlies.
