Another specimen, much like the last from Fort Laramie, has 

 the top of the head and posterior half of the back grizzled yellow, 

 gray, and black, anterior half of back and across shoulders nearly 

 to elbow with a much greater predominance of black ; basal half 

 of the convexity of the ears and the entire concavity, with the 

 edges, sides of neck and of body behind the forelegs, light-yel- 

 lowish. Legs and beneath black, as also muzzle and ears, with 

 the exception just stated. The fur is very full and soft, and the 

 feet densely clothed with long, crimped, soft hair. 



Another specimen indicates quite a different variety, with a 

 much closer resemblance to the red fox. The colour above is 

 light ferruginous, deeper toward the dorsal line ; beneath, white. 

 The hairs at the base are, as usual, lead colour. The fur, how- 

 ever, along and toward the dorsal line is terminated for the 

 greater part of its length by a rich chestnut, rather darker behind. 

 The long scattered hairs on the back are mostly black, tipped 

 with light yellow ; laterally, this fur is light ferruginous, fading off 

 into white toward the belly. This ferruginous is more distinct 

 immediately over the back. Inner sides of legs, sides of head, and 

 concavity of ears, likewise yellowish white. Upper part of muz- 

 zle, around the eye, and on top of head, grizzled chestnut, like 

 the back. Convexity of posterior surface of ear, black. The 

 sides of the soles also indicate black, although the legs are too 

 much mutilated to show distinctly the colour. The general colour 

 of the tail is yellowish white, deeper above : the long hairs of top 

 and sides tipped with black. Tip of the tail, white. The feet in 

 all the varieties are densely covered with hair on the under surface. 



In this species we find all the varieties of the common red fox, 

 Vulpes fulvus, as the chestnut, the black, the silver gray, cross, 

 &c. How far its range extends we are at present unable to state. 

 It probably, however, reaches the Pacific coast, and far to the 

 north in the Rocky Mountains. Indeed, we consider it very im- 

 probable that the ordinary red fox extends west of the Missouri. 

 As regards the eastern range, we have seen specimens from Fort 

 Laramie, and Audubon and Bachman refer to a skin from Fort 

 Union, at the mouth of the Yellowstone, which may possibly be- 

 long to the same species.
