240 The Ottawa Naturalist. [February 



1. Cervus Canadensis. Wapiti, or Elk. 



The elk, once numerous, is now extinct south of the Fraser, but I have 

 many reliable reports that a bunch still holds out in the mountains 

 at the head of Harrison Lake. 



2. Cariacns columbianus. Black-tailed Deer. 



Common in some localities and very scarce in -others ; the mule-deer 

 overlaps the range of this species on the summit east of Hope. 



3. Mazama montana. White Goat. 



Irregfular in its distribution on the highest peaks. 



4. Sciuropteriis oregoneiisis. Pacific Flying Squirrel. 



Generally distributed both on the mountains and lowlands. 



5. Sciurus donglassi. Douglas' Squirrel. 



Abundant at all elevations. 



6. Eutamias to-wnsendi. Townsend's Chipmunk. 



Common in the valley, and ascending the mountains to the park-like 

 glades near timber line at about 5,000 feet. 



7. Eutamias qiiadrivHtatus felix. Cascade Chipmunk. 



Abundant from about 5,000 feet to summits of the high rocky pc^ks 

 above timber line. 



The locality where I collected the type specimens was Lumsden 

 Mountain on 49th parallel, due north of Mount Baker. 



8. Arctomys caUgatus. Hoary Marmot. 



On all the alpine peaks, very rarely descending into the valleys. 



9. Aplodontia tufa. Sewellel. 



Very rarely seen in the valley, but more or less common on all the 

 foothills and higher mountains ; very abundant on the southern 

 slopes of all the higher mountains, where the ground is in some 

 places completely honeycombed with their underground runways. 

 It is never found away from water or small springs, and does not 

 ascend above timber line. Locally known as " Mountain Beaver." 



:o. Castor canadensis. Beaver. 



I have taken specimens as late as 1900, and a few still hold out in the 

 mountain streams, and occasionally in the Fraser itself. 



11. Mus decumanus. Norway Rat. 



Introduced. 



12. Mils musculus. House Mouse. 



Introduced and driving the indigenous white-footed mouse from most 

 of the houses and barns.
