P 10 British Columbia. 1920 



In April, 1909, the Bureau of Biological Survey, United States Department of Agriculture, 

 published a revision of the American genus Peromyscus by Mr. Wilfred H. Osgood. This work 

 has made it possible, to a reasonable degree of certainty, to classify, at least geographically, the 

 several species occurring throughout our range, represented by the following : — 



Peromyscus maniculatus arcticus (Osgood). Geographically distributed through the interior 

 of North-west Canada, from South-eastern Saskatchewan north along the Mackenzie River, west 

 to the upper waters of the Yukon River, then south to Eastern Alberta, in the Canadian and 

 Hudsonian zones. 



The British Columbia specimens identified as this species were taken in the Cariboo and 

 Telegraph Creek Districts. 



Peromyscus maniculatus oreas (Bangs). Type locality, Mount Baker Range, B.C., A. C. 

 Brooks, distributed through the Puget Sound region in the mountains and coast of Western 

 Washington, north to Southern British Columbia, south to the Columbia River. 



Peromyscus maniculatus Iceeni (Rhoads). A small white-footed mouse occurring on the 

 Queen Charlotte Islands, the type of which is from Masset, Graham Island. 



Peromyscus maniculatus macrorliinus (Rhoads). On the Coast of the Mainland of 

 Northern British Columbia and Southern Alaska ; type collected by the Rev. J. H. Keen at 

 the North Pacific Salmon Cannery, mouth of the Skeena River. 



Peromyscus maniculatus artemisice (Rhoads). Ranges through South-Central British 

 Columbia, south through parts of Washington, Idaho, and Western Montana, in the Transition 

 and Canadian zones ; type from Ashcrof t, B.C. 



Peromyscus maniculatus saturatus (Bangs). Type locality, Saturna Island, Gulf of Georgia, 

 B.C., to which it is entirely confined. 



Peromyscus maniculatus austerity (Baird). Geographic distribution over the Coast region 

 of Puget Sound, Washington, north to Southern British Columbia and including Vancouver 

 Island. 



Peromyscus sitlcensis prevostensis (Osgood). So far only recorded from Prevost Island, 

 Queen Charlotte Islands, and Forrester Island, Alaska. 



Genus Microtus. 



Voles, or meadow-mice, occur throughout the greater part of the Northern Hemisphere north 

 of the Tropics, and both species and individuals reach their maximum abundance in the Canadian 

 and Transition zones, a few species occurring to the north in the Hudsonian and Arctic zones, 

 even in the barren grounds north to the Arctic Coast. 



They adapt themselves to the most diversified conditions of environment, inhabiting all 

 classes of ground, from dry arid regions to wet swamps, a few species being aquatic in their 

 habits. 



The following species are represented in the Province of British Columbia : — 



Microtus drummondi (Aud. & Bach.) (Drummond's Vole). Geographically distributed from 

 the Hudson Bay to the west slope of the Rocky Mountains, the type locality being in the vicinity 

 of Jasper House, Alberta. 



Microtus townsendi (Bachman) (Townsend Vole). Distributed through the low country 

 west of the Cascades, from Port Moody, B.C., south to the Willamette Valley and to Yaquina 

 Bay, Oregon, in the Transition zone. 



Microtus tetramcrus (Rhoads) (Vancouver Vole). The distribution of this vole, so far as 

 known, is the southern end of Vancouver Island; type from Beacon Hill Park. Victoria, and 

 described from the type, and seventeen specimens collected near type locality. 



Microtus mordax (Merriam). Ranges from latitude 60, Rocky Mounrains and outlying 

 ranges, to Northern New Mexico; common in Canadian and Hudsonian zones; specimens recorded 

 from Nelson, Sicainous, Hope, Shuswap. Glacier, Okanagan, and Bennett City. 



Microtus serpens (Merriam). Distributed through the low country of Southern British 

 Columbia and Northern Washington between the Cascade Mountains and Paget Sound. 



Microtus nanus canescens (Bailey) (Gray Vole). East of the Cascades in Northern 

 Washington and Southern British Columbia; specimens recorded from Okanagan, Vernon, and 

 Ducks, B.C.
