78 CALiIFORNIA MAMMALiS. 



Type locality, Big Cottonwood Meadows, southeast of 

 Mount Whitney, Cal. 



Alpine Chipmunks are found high in the southern Sierras, 

 living in the crevices of the rocks about timber line, going occas- 

 ionally nearly to the summits of the highest peaks. They do 

 not occur much below ten thousand feet altitude. I found them 

 shy and hard to get, as when shot they were likely to fall in deep 

 inaccessible crevices among the rocks.

Klamath Chipmunks are common or abundant in the high 

 mountains from Inyo CounLy north to Idaho and Washington. 

 Their range in the Sierra Nevada is from about 4,000 to 8,000 

 feet altitude. They frequent the brushy places and the open 

 timber adjoining, but are rarely seen in thick forest. Three to 

 five young are born in May and June.
