grayer and duller, the spots with not as much white and more 
black, and not extending quite as far forward. Upper surface 
of tail with many black hairs and lacking the white edging; tail

Logan County; and Greeley, Weld County. It ranges south to 
about Lat. 40° and west to Lon. 104°. 
Habits. — The habits of this species are similar to those 
of C. t. pallidus. Its food is much the same, but as it is not 
as numerous as the other it is probably not as harmful. 
According to Bailey it bears as many as eight young in a 
litter.
