SOME ANIMALS OF YUKON TERRITORY 303 



and this overcrowding also causes an irregular migration 

 of sheep over areas inhabited by them. 



Therefore, all through the territory where sheep for- 

 merly existed near routes of travel or Indian villages, or 

 where their ranges were easily accessible to Indian hunt- 

 ing or mining districts, they have become scarce or ex- 

 tinct. Such active hunting of them, however, has re- 

 cruited adjacent regions only in a limited degree. 



The type of Ovis stonei was killed in the Cheonee 

 Mountains south of the Stikine River in British Columbia. 

 These sheep have been traced south near the head of the 

 South Fork of the Stikine to the Iskoot River, not far 

 from the head of the Nass River. The extreme southern 

 and eastern range is not known. It is probably between 

 latitude 55 degrees and 56 degrees, and west of longitude 

 126 degrees. 



The grayish color of the back and chest extends up 

 the neck to the face, and nearly all the sheep in the re- 

 gions south of the Stikine are uniformly colored. I know 

 of two sheep, killed near the type locality, which had white 

 necks and heads, and so much white hair intermixed with 

 the gray of the back that they were similar in color to 

 many of the sheep of the Pelly Mountains. Therefore, 

 it is fair to infer that there must be other exceptional cases 

 of light color among them. These sheep south of the Sti- 

 kine extend their range northward along the main Cassiar 

 range, probably crossing to it in the vicinity of the Dease 

 River. It is possible that some cross the Stikine directly 

 from the Cheonee Mountains, and reach the Sheslay 

 River district on the north, although there is probably an
