principal difference, real or supposed, seems to have been 
a darker color and possibly a finer coat. They ranged high, 
above timber-line at times. I have found a skull in Gunnison 
County at ii,ooo feet. One man told me that the mountain 
animal was a bison, and the plains animal a buffalo ! Rather 
a peculiar distinction. 
The Wood Buffalo of the North has been separated as a

Genus OVIS (Lat., A sheep) 
Ovis Linnaeus, Syst. Nat., loth ed., i., p. 70 (1758). Type, O. 
aries Linrasus. 
This genus containing the Wild Sheep is spread over the 
mountainous ranges of Asia and Western America, while 
one species, the Moufflon, inhabits Corsica and Sardinia.

Type locality. — Eastern slope of Rocky Mountains between Mis- 
souri and Saskatchewan rivers. 
Measurements. — Total length, about 60; tail vert., 3-5; height at 
shoulders, 40; length of horns around curve, 40-50, the record is 
52.50, from the Selkirk Mountains, B.C. (Reereation, vii., p. 11, 
1897). Hornaday gives two of 17I and 17^ for circumference 
around base, each of which measured 18 J when fresh; this is of 
course unusually large, but the horns were not extraordinarily long, 
being 34^ and 32 respectively; their widest outside spread was 21 
and 2 3 1, with distance between tips 17! and 16. Of course all
