life history of one of our least known big game animals. 
Through the generosity of Mr. Shiras and the kind cooperation 
of Governor Joseph M. Carey, and State Game Warden D. F. 
Hudson of Wyoming, a splendid pair of these animals were 
collected for the Biological Survey in December, 1913, the male 
serving as the type of the new suiispccies. 
In consideration of his remarkable work in originating 
modern methods of flash-light photography of birds and mam¬ 
mals and the interest he lias awakened, through this and by 
his writings, in animal life and its preservation, I take pleasure 
in offering a well-deserved tribute by naming this fine game 
animal in honor of George Shiras, 3d.
