S P . CH. Smaller than the American red fox. Tail very full and bushy. Soles of feet densely furred. Color white in the 

 adult; grayish lead color in the young. 



Without any good specimens of this species before me, excepting European ones, I shall not 

 go into a critical description of the species, nor attempt to discuss the question whether the 

 " blue" arctic fox be distinct from the white, or only a different condition of age. The arctic 

 fox is confined to the arctic regions of the globe, and has never yet been found within the limits 

 of the United States. 



According to Audubon and Bachman they are occasionally found in the northern parts of 

 Newfoundland, about latitude 52, and become more and more abundant as far north as 

 travellers have penetrated.
