description, written forty years since on the Columbia River, was in- 

 tended for the animal now before us. In courtesy, we should have 

 called it Columhiana, as suggested by Dr. Richardson, in Fauna 

 Boreali Americana, but that name would imply locality, and he has 

 not chosen a correct one. 



" The geographic range of this species, by our own observations, 

 appears to be limited on the north by the Columbia River, where a 

 few are sometimes found. South of the Umpqua River, it occupies 

 the country to the entire exclusion of the Virginia deer. It is seldom 

 seen east of the Cascade range of mountains, but abounds in Cali- 

 fornia. 



" The black-tailed deer never carries its tail erect when running, 

 and, viewed from behind, shows two narrow white lines of hair, instead 

 of the large, white, and elevated tail of the Virginia deer, seen in the 

 same position. When on the prairies, in long grass, it has a habit 

 which is somewhat peculiar, — that of frequently springing up to a con- 

 siderable height to get sight of its pursuers. Most of the bucks killed 

 in the mountainous regions of the southern part of Oregon had a basal 

 antler on the inner side of the horn, which was directed upwards and 

 backwards ; those killed on the plains in California seldom had it."
