 of the genus Hke. They cHmb trees but Httle. The young are

Eutamias quadrimaculatus senex Ai.i.i>:n. (Old.) 



ALLEN CHIPMUNK. 



Similar to quadriiHch-ulatiis: ears considerably shorter and 

 less pointed; facial stripes not as distinct; light spots behind 

 the ear smaller and tinged with ashy; white markings grayer; 

 size about the same. 



Type locality. Donner Pass, Placer County, California. 



Allen Chipmunks range from the higher peaks above the 

 Yosemite Valley north along the Sierra Nevada and Cascad.e 

 Mountains to central Oregon ami west on the Siskiyou Moun- 

 tains. I obtained Chipmunks in the Warner Mountains which 

 I refer to this subspecies. Allen Chipmunks seem to be the 

 northern and high mountain form of qmidriniaciilatus.
