NOTES ON MAMMALS COLLECTED AT MT. RAINIER, 



WASHINGTON 



By MARCUS WARD LYON, Jr. 

 Assistant Curator, Division of Mammals, U. S. National Museum 



In the summer of 1905 it was my good fortune to accompany the 

 Mazamas 1 'to Mt. Rainier, Washington, on their annual excursion, 

 and through the kindness of the outing committee an outfit for col- 

 lecting small mammals was carried with the regular baggage by 

 pack train to the permanent camp, where I collected for the U. S. 

 National Museum the specimens mentioned below. 2 This camp 

 was located near timber-line, on the south side of the mountain, in 

 Paradise Park, at an elevation of about 5,500 feet. 3 A few speci- 

 mens were secured at Longmire Springs, 2,800 feet altitude. 



M ARM OTA CALIGATA (Eschscholtz) 

 Hoary Marmot 



One specimen, an adult female, captured above camp, near snow 

 limit. This species was fairly common in colonies in Paradise Park. 

 They were unusually tame, as a rule, often permitting photographers 

 to approach within a few feet, and could usually be called out of 

 their rocky dens by whistling shrilly. It is commonly called "whist- 

 ling marmot," or simply "whistler," in distinction to "marmot," a 

 term popularly applied to the mountain beavers, Aplodontia.
