Osgood — Mammals From Mount McKinley. 63 



Vulpes fulvus subsp, 



FOX. 



Very abundant, especially above timber. Several were seen, including 

 black or nearly black individuals. No specimens. 



Ursus horribilis phaeonyx Merriam. 



GRIZZLY BEAR. 

 Six grizzlies were secured, three adult females, and three cubs, the latter 

 being the offspring of one mother. They show inucli variation in color, 

 especially the cubs, one of which is very pale, another very dark, and the 

 third almost exactly intermediate. All were killed high up on the moun- 

 tain slopes far above timber, to which region they seem largely confined. 

 The name " Glacier Bear" is locally applied to light colored examples of 

 this grizzly. 



Ursus americanus Pallas. 



BLACK BEAR. 



A black bear was seen on the Kantishna River and many tracks were 

 noted in various parts of the timbered region, where the animals are evi- 

 dently very abundant. 



Lutra canadensis (Schreber). 



OTTER. 



Otters occur in limited numbers. No specimens. 



Lutreola vison subsp. 



MINK. 

 Common. Several were seen along the Kantishna and Tanana Rivers 

 and numerous skins were seen in the possession of trappers on theToklat. 



Mustela americana actuosa Osgood. 



MARTEN. 



Common throughout the timbered part of the region. Trappers' skins 

 seen on the Toklat were noted as being light colored and therefore prob- 

 ably represent the subspecies actnosa. 



Quio luscus (Linnaeus). 

 WOLVERINE. 



Common throughout the region, except in the timberless belt, and doubt- 

 less also to be found there. Skins were seen among the trappers on the 

 Toklat. 



Sorex sp. 



SHREW. 



No specimens of shrews were secured, but that they occur is attested by 

 the fact that the remains of one were found in the stomach of a bear. 

 Those of probable occurrence are Sare.r personatus ardicus, S. ohscurus, S. 

 tuii(h-ciif<is, and >S. exiniiuv.
