4t. Cants lupus. Gray Wolf. Formerly abundant, but now 

 comparatively scarce. 



5. Cants latrans. Prairie Wolf. Formerly exceedingly 

 numerous, but now greatly reduced in numbers, though still more or 

 less troublesome. 



O. Vulpes viilfi-aris, var. fulvus. Common Fox. Common. 

 The color is generally grayer than in the eastern form, and the 

 "black" and "cross" varieties are more frequent. In a series of 

 some thirty-five or forty skins, taken in the winter at Montgomery, 

 which I had an opportunity of examining, none were as brightly col- 

 ored as the red fox of the Eastern States. One was entirely black, 

 and nearly half of the others were more or less well-marked " cross " 

 foxes, some of them typically so, but they graded almost insensibly 

 into the ordinary type. The V. macrourus seems to represent only a 

 common phase of the "cross" fox, a type so much more common in 

 the western and elevated parts of the continent than at the eastward. 



1. Mustela martes. Marten. Common. 



8. Mustela Pennanti. Fisher. Said to be more or less 

 common. 



O. Putorius ermineus. Ermine Weasel. Common. 



10. Piitorius lutreolus, var. vis on. Mink. Common 

 along the streams up to about ten thousand feet, above which I could 

 not obtain evidence of its occurrence. 



11. GrUlo luscus. Wolverene. Said to be not uncommon. 

 Saw the skin of one taken near Montgomery. 



Ifc. Mephitis mephitica. Common Skunk. Common, 

 ranging to above timber line. 



13. Taxidea Americana. Badger. Common in South 

 Park. 



14. Ursus arctos, var. Bear. Common. Both the black and 

 cinnamon varieties occur in about equal numbers. The cinnamon vari- 

 ety is represented as averaging the larger, and as being the more dan- 

 gerous to encounter. Both vary greatly in color and size, and appear 

 evidently to intergrade. The cinnamon is often quite gray, when it 

 often passes for the grizzly, though not generally regarded as the 

 "true" grizzly. 



15. ntson American 11$. American Bison. A few still 

 remain in the southern portion of South Park, chiefly near Buffalo 

 Springs. A small band came up the valley of the Platte from the
