October, 1902.] MAMMALS OF KEEWATIN. 51 



near 'Narrows'), Swampy Lake, Hill River (at various points). Steel 

 Ri\er, Hayes River, and York Factor\'. One was also taken by my 

 brother on Charchill River, 15 miles above Fort Churchill. Mossy 

 spruce woods seemed to be their favorite iiabitat, but we also fre- 

 quently trapped them in deciduous or mixed woods, and occasionally 

 in willow thickets in swamps. They inhabited the larger wooded 

 islands in Knee Lake. On lower Plill River as well as on Steel 

 and Hayes rivers we toolv only an occasional one, and at York Fac- 

 tory a week's trapping- yielded but three, all of which were caught 

 about the post buildings. None were found at Fort Churchill, or any- 

 where on the tundra, and several nights' careful trapping l)y my 

 brother on Churchill River above the post yielded but one. 



Of this series of nearly seventj' specimens all but six are in the 

 normal red-backed pelage. The exceptions may be briefly referred 

 to. One. from Robinson Portage, has a few black hairs scattered 

 over the back, perceptibly darkening the dorsal stripe. One, from 

 Oxford Lake, taken September 12, has the dorsal stripe dusky, sides 

 only slightlj' dai-ker than normal, and belly j^ellowish v/hite. One, 

 taken on upper Hill River September 5, has the dorsal stripe dusk}' 

 brown, the belly and sides about normal, and the back nearl}' concolor 

 with sides; the dorsal stripe is indicated onlj' by a slight admixture of 

 red. Of the three specimens taken at York Factory, one is normal; 

 another, probably in left-over winter pelage, differs fi'om the average 

 only in being slightly brighter. The third is j'ellowish white beneath, 

 with nearly normal sides, and dorsal stripe indicated only by a slight 

 darkening of the dorsal area. One, taken on Churchill River, 15 

 miles above Fort Churchill, has the dorsal area dull red and only 

 faintly indicated, with dull-brown sides and ashj'-brown lower parts. 

 It is immature and measures: 133; 30; 20. A skin from Fort Churchill 

 in the U. S. National Museum (No. 4206) has a seal-brown dorsal 

 stripe, which extends forward nearlj' to the eyes, and dull, yellowish- 

 brown lower parts and sides. 



Three adults from Norway House avei'age: Total length 134; tail 

 vertebrae 39; hind foot IS. Four from Robinson Portage average: 

 136.5; 38; 18. Five from Knee Lake average: 138; 42; 19. Three 

 from York Factor}^ average: 141; 40; 19. 



Microtus drummondi (Aud. and Bach.). Drummond Vole. 



We found this vole rather common in suitable locations throughout 

 the region between Norway House and Hudson Bay. It seemed most 

 abundant in the partiall}^ cleared areas near the posts, and as it readily 

 takes up a residence in the houses and stores, it becomes a decided 

 pest. A large series was collected, including specimens from the fol- 

 lowing localities: Norway House, Echimamish River, Robinson Port- 

 age, Oxford House, Steel River, York Factory, Cape Churchill, and 

 Fort Churchill.
