OcTOBEE,l902.] MAMMALS OF KEEWATIN. 45 



National Museum from Hudson Bay closely resembles those from 

 Norway House, but is slightly more tinged with yellowish brown 

 beneath. An albinistic specimen from Norwaj'^ House is nearly white 

 above, slightly tinged with light brown, with a brownish area on the 

 middle of the back; the tail is verj'' light brownish above, and lighter, 

 about normal, beneath. No skulls from the Hudson Bay region are 

 available for comparison. 



Sciurus hudsonicus (Erxleben). Hudson Bay Red Squirrel. 



We found the red squirrel abundant and generally distributed 

 throughout the region to within a few miles of York Factory, where 

 the trees dwindle to such an insignificant size as not to afford the ani- 

 mals a congenial home. At Fort Churchill I saw a specimen which 

 had been secured a few miles up the river, where good-sized spruce 

 trees occur and the animals are said to be fairlj- abundant. An adult 

 male taken at Noi'way House June 18 is in nearly full winter pelage, 

 the summer coat just beginning to appear in patches on the face and 

 back, the lower parts still showing the heavy grayish vermiculations, 

 and the red median dorsal stripe of the winter pelage being present. 

 The tail is concolorwith the back, and is edged with yellowish gray. 

 All the other specimens taken at Norway House and at various points 

 between that post and Oxford House late in June and early in July, 

 and on the return ti'ij) between Steel River and Norwaj^ House dui'ing 

 the first half of September, are in summer pelage and appear to repre- 

 sent two phases of color. By far the greater number are very dark 

 reddish above, the red suffusion tingeing the lower parts quite appre- 

 ciably in many cases; the tails are bordered with grayish or reddish 

 indiscriminately. 



Tamias striatus lysteri (Richardson). Northeastern Chipmunk. 



A specimen collected by C. Drexler at James Bay is recorded in the 

 U. S. National Museum catalogue. It can not now be found, but notes 

 regarding it, made years ago by Dr. C. Hart Merriam, indicate that it 

 is referable to the present form. 



Eutamius neglectus (Allen). Lake Superior Chipmunk. 



We obtained about a dozen specimens which were collected by Mr. 

 William Campbell at Oxford House during July, August, and the 

 early part of September. Chipmunks were reported to be rather 

 common about Oxford Lake, but we failed to see any at that point, or 

 at any other on our entire trip except the shore of Pine Lake, where 

 we observed one September 13. 



The specimens secured were preserved in formalin and skinned on 

 our return in September. The average measurements of 6 are as 

 follows: Total length 217; tail vertebra 101; hind foot 31. « 



This series agrees essentially with a series taken by Gerrit S. 



"All measurements are in millimeters unless otherwise stated.
