The Gray Foxes, included in the present genus, are represented in 
North America by a number of species and races varying considerably 
in size, the smallest not being more than half that of the well-known 
eastern Gray Fox. They are very handsome animals, but not pos- 
sessed of the cunning equal to that of the Red Fox, and in the struggle 
for existence seem, in their diminishing numbers, to be giving way to 
their more fit relative.
