326 Notes on a Collection of Mammals. [zoe 



The only adult specimen, No. 42 3 , is in worn pelage. The 

 ends of the hairs are worn oflf along the back, leaving it dark 

 brown in places. The young, No. 44 3 , has long silky pelage 

 of a grayish tawny color with interspersed black hairs. 



17. Scapamis tow7isendii (Bach). Townsend's Mole. 



A single specimen was taken at Red Point in a cellar. The 

 marks of moles were seen all over the high Sierras especially about 

 snow fields on Mt. Tallac, but no specimens were taken. 



18. Putorius arizonensis Mearns. Arizona Weasel (?) 



A Putorius, provisionally referred to this species, was taken 

 high up on Mt. Tallac July 29. It was seen in a boggy piece of 

 meadowland searching among dwarf willows. A few days later 

 another specimen was seen in a similar place, but it was not 

 secured. 



The following is a list of the mammals seen or known to 

 inhabit the Sierra Nevada, but no specimens were taken. 



19. Cariacus Columbianus (Rich.) Black-tailed Deer. 

 This deer is common all through the mountains, in summer, 



up to 9500 feet. In the fall it migrates from the higher altitudes 

 down to about 4500 feet and lower, but usually it is not found 

 above that altitude in winter. 



20. Antilocapra aniericana Ord. Antelope. 



The antelope has been seen along the eastern base of the 

 Sierra Nevada in the Carson Valley, but its range does not 

 reach up into the mountains. 



21. Ardomys flavivenier Aud. and Bach. Yellow-bellied 

 Marmot. 



Marmots were first seen near the Central Pacific Railroad at 

 about 6000 feet. They were common about Summit Station and 

 on the mountain sides along Donner Lake, frequenting granite 

 ledges and rock piles. But on Mt. Tallac they seemed the most 

 abundant, frequenting the slopes of the mountain from near Lake 

 Tahoe to the very summit. About the summer resort at the 

 Glen Alpine Springs, near the base of the mountain, they were 

 abundant, and when everything was quiet about the place they 

 often approached close to the kitchen in search of bits of vegetables
