The animal has an extremely northern range. There are two 
species, the one referred to reaching from Maine and New 
Brunswick westward to Lake Superior, and the Barren Land 
Caribou {^Rangifer groenlandicus), far to the north in Green- 
land and Arctic America. They subsist for the most part on 
lichens, mosses, and small shoots and twigs of trees. 
This is the only member of the Deer family in which the 
female as well as the male has antlers. The antlers are very 
irregular in development, and differ much in shape ; the tip 
and also the brow antler are generally palmated to some 
extent. 
The Caribou represents in the New World the reindeer of 
the Old, and by training might be made useful to the Esqui- 
maux as the latter is among the Lapps. 
The Mule Deer (^Cervus macrotis) and the White-tailed 
Deer {Cervus leucurus) are both found on the plains of the 
United States, west of the Missouri river. The latter much 
resembles the common Deer, of which it is probably but a 
variety, while the former is considerably larger, and differs in 
the shape of its horns.
