Of the above list of 213 species and subspecies, about 20 are 

 maritime, about 60 range across the continent, and about 130 have 

 a more limited range. Of these a small number is limited to 

 the immediate vicinity of the Northwest Coast, a few to the 

 Upper Missouri region, and a large number to the Rocky Moun- 

 tain plateau and the various mountain ranges of the western half 

 of the continent. 



The Cold Temperate Subregion has been divided into four 

 faunce, as follows: (1) Hudsonian, (2) Canad/a//, (3) 

 Aletdian, (4) Sitkan. The first two have been long recog- 

 nized, and their boundaries are well known. They were first 

 mapped by Dr. Merriam 1 in 1890, and more recently by the 



1 North American Fauna, No. 3, map 5.
