the tip, which is black for 1J in.; the upper side of tail is all 

 black, except base and tipping at sides and end, which are buffy, 

 the same as the body colour. The teeth are yellow (in the young 

 they are white). 



Citellus (Ictidomys) tridecemlineatus (Mitchill). Thirteen-lined 



Spermophile. 



The little striped ground-squirrel is apparently not found 

 farther north than the vicinity of Athabaska Landing. We 

 found it common on the road about ten miles south of that point, 

 on May 13. 



Eutamias borealis (Allen). Liard River Chipmunk. 



The chipmunk is generally distributed wherever there are 

 suitable places throughout the region covered during our jour- 

 ney north to Great Slave Lake. We noted it on the Athabaska, 

 a short distance below Athabaska Landing, on May 18. It was 

 fairly abundant in the vicinity of Fort Smith, where a specimen 

 was taken on June 15. It measured: length, 210; tail, 96; hind- 

 foot, 30. At Fort Resolution, on September 27, Seton saw a 

 chipmunk busily engaged in gathering the seeding of heads of a 

 species of grass which grows abundantly about the post. One 

 was noted on Slave River, near Point Ennuyeux, on September 

 29, and another, the last one seen on the Athabaska near Middle 

 Rapid, on October 20. 



Sciurus hudsonicus Erxleben. Hudson Bay Red-SquirreL 



The red-squirrel is quite generally distributed through the 

 wooded country, excepting the extreme northern edge of the 

 timber, where it is usually absent, or if found, is rare. During 

 the summer of 1907, however, it was much less abundant than 

 usual. It was occasionally noted during our northward journey, 

 but was much less common in the fall during our homeward trip. 

 The stomach of one taken at Fort Reliance, at the eastern ex- 

 tremity of Great Slave Lake, on September 16, contained the 

 seeds of spruce and fragments of mushrooms. A male from 

 Fort Reliance measured: length, 336; tail, 147; hind-foot, 53.
