Head of Prongbuck. 
The PRONGBUCK or PRONG-HORN (Antilocapra americana). 
Although commonly termed an antelope, this ruminant differs from 
all the members of the Lovide by the forking of the horns. These are 
annually shed from their bony sheaths and replaced by a new pair, 
which commence to grow up beneath the old ones before they are cast 
off. In consequence of this, the species is generally regarded as repre- 
senting a family (Axéelocapride) by itself. Horns absent or rudimentary 
in the female. Ears long and pointed, tail short, and neck maned. 
General colour chestnut, with a white rump-patch, and white bars on 
the throat. Height at shoulder, 36 inches ; weight, 70 to 80 lbs. clean. 
Distribution—Western North America, from British Columbia 
to Mexico.
