MAMMALS URSIDAE URSUS HORRIBILIS.

The range of the grizzly bear is quite extensive through North America though less so than 

 that of the common black bear. It appears first to occur on the Missouri, above Fort Pierre, 

 and becomes more and more abundant higher up on the Missouri, and especially on the Yellow 

 stone ; thence to the Kocky Mountains, which it inhabits throughout its entire extent in the 

 United States. It also langes to the Pacific, though not found on the coast north of the Colum 

 bia river. To the north it extends far into the British possessions, and southward into Mexico ; 

 how far, however, is not known. 



Richardson credits Lewis and Clark with the name of Ursus ferox, as first applied to this 

 animal ; I have not been able to find this name in their report, and am inclined to believe it a 

 translation by Kichardson of one of their vernacular appellations. To the best of my present 

 knowledge, the first tenable name is the one imposed by Ord as quoted above. 



For a detailed account of the skull and skin of a variety of grizzly from Sonora and the 

 Copper Mines of New Mexico, which I call Ursus horribilis var. horriaeus, I refer to the report 

 of the United States and Mexican Boundary Survey.
