SPECIES OF MAMMALS OF THE PACIFIC AREA 111 



squirrels. The pygmy squirrels proper are found from the Phil- 

 ippines and Borneo to Java and Sumatra. They are rarely 

 collected and may occur unrecorded on other islands. 



Ground Squirrels 



The ground squirrels commonly live in burrows or among 

 rocks. Some may be found in open country while others occur 

 in the forest. 



The Arctic Ground Squirrel (Citellus parryi), found on the 

 more landward of the Aleutians as far west as Unalaska Island, 

 is relatively large, its total length being about seventeen inches, 

 of which the tail is about four and one-half inches. The upper- 

 parts are brownish, with irregular grayish spots, indistinct in 

 worn pelage. The head is richer brown, the underparts rusty 

 overlying grayish. 



The Asiatic Chipmunk (Eutamias sibericus) resembles the 

 common western chipmunks of the United States. Its dark back 

 bears four whitish stripes and the sides are rust-colored. In 

 length it is about nine inches, of which the tail is some four 

 inches. Besides ranging widely in Siberia and northern China, 

 the Asiatic chipmunk is present on the Kurile and the northern 

 Japanese Islands. 



The Red-cheeked Ground Squirrel {Dremomys everetti) 

 has reddish cheeks and a relatively long muzzle. It is known 

 only from a very limited area in Sarawak, Borneo. A closely 

 related species occurs in Formosa and others in the mountains 

 of China, India, and Malaya. 



The Striped Ground Squirrel (Lariscus) is characterized 

 by three or four black stripes on the back. It is found from 

 the Malay Peninsula through Sumatra to Java and Borneo, as 

 well as on some of the adjacent islands. 



The Pygmy Ground Squirrel {Glyphotes) is a small squirrel 

 with flank stripes of white and black and broad front teeth. It 

 is known only from a very few specimens collected on Mount 

 Kina Balu, British North Borneo.
