Sp. Ch.—S maller 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 
a 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.
