ocr., 1899.] MAMMALS. 89 
Myotis lucifugus longicrus (True), 
At Wagon Camp, July 17, Walter K. Fisher shot one of these bats. 
Small bats were abundant here, but kept so much in the forest that 
they were hard to shoot. 
Myotis californicus (Aud. & Bach.), California Bat. 
A single specimen of this species, collected on Mount Shasta by C. H. 
Townsend, is recorded by Miller in North American Fauna, No. 13, 
page 71, October, 1897. 
Myotis yumanensis saturatus Miller. 
Common among the alpine hemlocks at Squaw Creek Camp, where 
they were seen every night, darting in and out of the flickering light 
of the camp fire. Here I shot one the evening of August 3, and four 
the evening of August 9. Late in July and early in August small bats, 
probably the same species, were seen nearly every evening at the tem- 
porary camps on or near upper Mud Creek. The species is interesting 
as the only bat secured in the Hudsonian zone. 
Vespertilio fuscus Beauvois. Large Brown But. 
Common at Wagon Camp, where Vernon Bailey shot one July 17, 
and I shot three the evening of July 28. Many more could have been 
killed if desired. In 1883 C. H. Townsend obtained it at Sheep Rock. 
The species is one of the commonest in the foothills and valleys, and is 
easily recognized on the wing by its large size and its character of flight. 
[Arctomys flaviventer (Aud. & Bach.). Mountain Marmot. 
It may be asserted with confidence that no marmots of any kind live 
on Shasta. Our collectors were at work on the mountain from July 15 
until October without seeing a single individual. Moreover, when 
Vernon Bailey and I made our trip completely around the peak the 
latter part of July we kept near timberline all the way and made a 
special search for marmots, but were unable to tind a trace of their 
presence. | 
Spermophilus douglasi (Richardson). Oregon Ground Syuirrel. 
Common at Sisson and in McCloud and Shasta valleys, whence it 
ranges up through the manzanita chaparral of the basal slopes nearly 
to Wagon Camp. At Sisson R. T. Fisher collected eight during the 
first half of September, and says of them: “One of the few really plen- 
tiful mammals at Sisson. Hardly an acre in the valley is free from 
their burrows. Under the barns and houses, in the fields, along the 
hot slopes east and west of. the town, and even in the woods, one con- 
stantly sees them. At the timeI write of, September 1-15, they seemed 
to be feeding chiefly on. acorns and chinquapins—acorns in the valley, 
chinquapins on the western slopes. In behavior they were wild and 
sneaking; at all times, difficult to approach. None appeared to have 
hibernated.”
