34 HOOFED ANIMALS 
is very widely distributed throughout Alaska and the Yukon 
Territory. Ten years ago it was abundant on the Kenai 
Peninsula and at the head of Cook Inlet, but many have been 
killed, and the number has been greatly reduced. Recently 
Congress has passed a law intended to protect not only the 
White Sheep but all the large game animals of Alaska; but 
it is fatally defective in the extent to which it permits big 
game to be slaughtered by natives and “prospectors.” 
In the White River country of southwestern Yukon Ter- 
ritory, not far from the Alaskan boundary, individuals of this 
species often develop long and widely spreading horns that 
differ decidedly from the usual close spiral of typical spec- 
imens. An example is shown herewith. It suggests abun- 
dant horn food and an effort on the part of Nature to develop 
a wide-horned breed. 
The White Mountain Sheep of the Kenai Peninsula have 
been described as a subspecies, and are known as Ovis dalli 
kenatensts. Their horns are small, and in form exhibit the 
close spiral. 
Tue Buack Mountain SHEEP,! of northern British Co- 
lumbia, is distinguishable by the dark-brown color of its sides 
and upper parts generally, and by its white abdomen. It is 
of the same size as the white sheep, but the two species to- 
gether form a striking contrast. The Black Sheep species 
develops its darkest colors in the mountains north and south 
of the Stickine River. Farther north this species and the 
white sheep have been found inhabiting the same locality, 
and therefore we have ventured to show both in one plate.
