A series of 13 specimens was taken on the Cheonnee Moun- 

 tains, July 21-24, of which four were old nursing females, one 

 an adult non-breeding female, three half -grown and five 

 quarter-grown young. There are also two adults from Shes- 

 ley River, taken August 23 and 27, and an old male from 

 Level Mountain, taken September 16, making a total of 16 

 specimens. 



The quarter-grown young from the Cheonnee Mountains, in 

 the first, soft, woolly pelage, differ little in general pattern of 

 coloration from the adults from the same locality, but the 

 lower back is less varied with black. The pelage in all of the 

 adults is thick and heavy but more or less worn, and there is 

 considerable individual variation in the amount of black in 

 the dorsal pelage. Generally from the nape posteriorly to the 

 middle of the back, including the shoulders and sides, the 

 color is whitish gray, and the rest of the dorsal surface blackish 

 varied with rusty brown; but in one of the Shesley River 

 specimens the prevailing color above over the anterior half of 

 the body is black varied with gray. 



A single adult male from Level Mountain measures as fol- 

 lows: Total length, 792; tail vertebrae, 210; hind foot, 100; 

 ear, 3 2 . Five breeding females (four from the Cheonnee Moun- 

 tains and one from Shesley River), measure: Total length, 668 

 (659-672); tail vertebras, 189 (180-200); hind foot, 95 (93- 

 96); ear, 34 (33-37). 



Mr. Anderson states that these animals were first met with 

 in the Cheonnee Mountains, they not being found in the im- 

 mediate neighborhood of Telegraph Creek. "In the Cheon- 

 nees, as elsewhere," he says, "these animals are found in dry, 

 rocky places. They are very wary and shy." On Level 

 Mountain, September 8-21, their "burrows were frequently 

 seen in the numerous rocky localities, but the animals were 

 undoubtedly beginning to hibernate. The whistle of one was 

 heard on September 15, and Dennis [the Indian helper] shot
