264 THROUGH THE MACKEI^ZIE BASIN 



Barren Grounds, Liverpool and Franklin bays, from the 

 Yukon, and from the Mackenzie Eiver. They breed once a 

 year and have several young at a birth. They live in bur- 

 rows, as described by Mr. Preble, who secured specimens 

 from a point 150 miles north of Fort Churchill. Doctor 

 Eussell also obtained three examples at Herschel Island, 

 situated to the west of the outlet of the Mackenzie River. 



Eichaedson's Speemophile — Citellus richardsoni 

 (Sabine). 



Richardson gives its range as not extending beyond lati- 

 tude 55° north, and in the neighbourhood of the north branch 

 of the Saskatchewan River, but I do not think I ever met 

 this animal anywhere in the country. 



Steiped Speemophile — Citellus tridecemlineatus 

 (MitcheU). 



Richardson found this species quite common at Carlton 

 House, Saskatchewan. It is also said to have been abundant 

 in all favourable localities between the international bound- 

 ary and the North Saskatchewan River. I do not think it 

 is an inhabitant of the regions beyond that stream. 



WooDCHUCK — Geouwd Hog — Marmota monax canadensis 



(Erxleben). 



Mr. B. R. Ross gives latitude 62° north as the northern 

 limit of this animal. In 1889 three trade skins were obtained 

 at Fort Simpson. I do not remember if I ever saw any 

 examples at Fort Anderson or elsewhere in the Mackenzie 

 River District, but at Fort Chipewyan, Athabasca, several 

 were observed, and in May, 1885, I sent five skins to Dr. 

 R. Bell, of the Geological Survey, Ottawa. At Cumberland 

 House, Saskatchewan, however, the Company annually trade 

 and export a few skins, which bring only a few cents in the 

 London market. They are not common at any of the posts 

 of the Pas, Moose Lake, and Grand Rapids. In 1888 one 

 specimen was obtained at Pelican Narrows. The adjoining
