erto-overlooked note in the American Naturalist (11, 1869, p. 531 ) r 

 where it is given as Klickitat Pass, Cascade Mountains, 4,500 feet. 



APLODONTIA MAJOR RAINIERI Merriam 



Mountain Beaver 



Two specimens, not fully adult, from Paradise Park. Judging 

 by the numerous holes and tunnels in the hillsides, this is a com- 

 mon species, although none were seen but the two individuals 

 taken in steel traps placed in their burrows. The burrows or tunnels 

 are about 8 to 9 inches in diameter and were always found in groups 

 or colonies. Near their openings on the surface were often seen little 

 piles of cut sticks and pieces of green herbage. The stomachs of 

 the two individuals secured were distended with soft green vegta- 

 tion. Locally this species is often called "marmot" and sometimes 

 "high-ground muskrat." 



PEROMYSCUS OREAS Bangs 



White- footed Mouse 



Common in the dense woods at Longmire Springs, but much 

 less abundant about the permanent camp in Paradise Park. Twenty- 

 five specimens secured. 



EVOTOMYS GAPPERI SATURATUS Rhoads 



Red-backed Mouse 



The most common of the small mammals in Paradise Park, where 

 20 individuals were collected. None were taken at Longmire 

 Springs. They were found indifferently in wooded or in open 

 and bush-covered ground. 



MICROTUS ARVICOLOIDES (Rhoads) 



Meadow-mouse 

 Six specimens from Paradise Park. 



PHENACOMYS OROPHILUS Merriam 



False Meadow-mouse 



Four specimens from Paradise Park. This and the two preceding 

 species made numerous burrows and runways about boulders and in 

 banks in the park.
