and northern North America. Each mountain system seems to 

 have one or more kinds of these animals, and this is notably- 

 true of the mountains of California. In the Warner Mountains 

 of Modoc County there is a distinct species, the Warner Moun- 

 tain cony (Ochotona taylori), and on the Sierra-Cascade range 

 from Mount Shasta to Mount Whitney there are no less than 

 three slightly different forms. The northernmost of these, the 

 gray-headed cony (Ochotona schisticeps schisticeps) , is found

from Mount Shasta south to the vicinity of Lake Tahoe ; the 

 southernmost one, the Mount Whitney cony ( Ochotona schisti- 

 ceps alhatus), occurs in the vicinity of the peak for which it is 

 named ; while the third, the Yosemite cony, occupies the higher 

 portions of the Yosemite National Park and adjacent territory. 

 This last form was discovered by the field parties of the Cali- 

 fornia Museum of Vertebrate Zoology in 191 5, when engaged 

 in making a zoological survey of the Park. It has been named 

 Ochotona schisticeps muiri, in remembrance of that most gifted 

 of Sierran naturalists, John Muir.
