MAMMALS CERV1D.E CARIACUS MACROTIS. 



71 



Although this animal was not actually observed, Indians of Nevada 

 spoke of its occurrence there, and had in their possession skins and horns 

 said to have been obtained in the mountains. 



Remains of a Moose (Alee americana), said to have been killed in 

 South Park, Colorado, in 1871, were observed by the expedition. The 

 statement is open to doubt ; if correct, it fixes the southernmost limit of the 

 species.

Specimens. 



An abundant and generally diffused species throughout the West, but 

 especially east of the Rocky Mountains, where it is the only Black-tailed 

 Deer certainly known to be of regular occurrence. West of the mountains, 

 it is associated with C. coluntltianus, the true Black-tailed Deer, an appar- 

 ently distinct species.
