FIFTH ANNUAL REPORT. 119 
sula of Lower California, save as they wander northward along 
the western edge of the Colorado Desert, are of the same species 
as those in the Grapevine Mountains, bordering Death Valley, 
and they will be so set down on the map of distribution. The 
status of the Mexican specimens has been determined by Dr. Mer- 
riam, and they represent an entirely new form. 
It is very desirable that good skins of adult Mountain Sheep, 
in winter pelage, should be obtained from San Francisco Moun- 
tain, the cafion of the Colorado, Arizona, from the Organ Moun- 
tains, New Mexico, the Seri Mountains and southern California, 
the Sierras of eastern California, and in fact all points south of 
Lat. 37°. Hunters in these localities can easily promote the 
further investigation of this subject by taking the trouble to pre- 
serve skins in complete form, with their respective skulls intact. 
Mexican naturalists, especially, should take pains to ascertain 
the range of the Mountain Sheep in their country.
