SCIUKID^ 83 



These Chipmunks are found in thicker forests than most 

 of the genus Hke. They dimb trees but little. The young are 

 born from the latter part of May until in July. 



Eutamias quadrimaculatus senex Allen. (Old.) 



ALLEN CHIPMUNK. 



Similar to quadrimaculatus; 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 and 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 quadrimaculatus. 



Eutamias hindsi Gray. 



HINDS CHIPMUNK. 



Light face stripes grayish white in winter, tinged with 

 ochraceous in summer; whitish ear stripe and spot behind the 

 ear distinct, most so in summer; other dark stripes of back in- 

 distinct, the three middle stripes black, edged with rusty in win- 

 ter; inner pair of light stripes wood brown or russet grizzled 

 with gray in winter pelage, deeper brown in summer ; outer pair 

 of light stripes rather narrow, grayish white in winter pelage 

 tinged with fulvous in summer; sides light burnt umber in 

 summer, gray tinged with umber in winter; lower parts dull 

 white in winter, washed with fulvous in summer; tail long, 

 broad, the stripe underneath cinnamon rufous or Hght chestnut, 

 rather narrowly bordered with black, edged with grayish white. 



Length about 250 mm. (9.85 inches); tail vertebras 118 

 (4.65); hind foot 36 (1.42).
