Inhabits N. America; in the plains in summer and in the moun- 
tains in winter. Called the Goat. Mexico (Coulter). Brit. Mus. 
Dr. Coulter brought a head from Mexico which had the face dark 
brown, and the horns large, wide-spreading and much hooked at the 
tip, like the 4. palmata of H. Smith (Proc. Zool. Soc. 1826, 121). 
This is probably only a larger variety in the summer fur.
