17. Scapanus townsendit (Bach). Townsend’s Mole. 
A single specimen was taken at Red Pointinacellar. 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 arizonensts 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 foie 
above that altitude in winter. 
20. <Antilocapra americana 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, Arctomys flaviventer 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 they 
often approached close to the kitchen in search of bits of vegetables
