THE MAMMALS OF MOUNT MAZAMA.

the cold streams about Fort Klamath, the two American subgenera 
of Water Shrews (Neosorex and Atophyrax) fish and swim in the 
same pools. 
Several mountain mammals of wide distribution are conspicu- 
ous by their absence. Thus the Elk or Wapiti {Cervus canadensis), 
Mountain Sheep {Ovis canadensis)^ Mountain Goat {Oreamnos mon- 
ianus), Wolverine {Gulo luscus), and Fisher {Mustela canadensis) 
have not been known to inhabit the region in recent years. The 
Raccoon (Procyon) and common small bat of the Pacific coast (Ves- 
pertilio nitidus) probably occur in the Klamath region but were not 
obtained by us. 
Since the time spent on Mount Mazama and at Fort Klamath 
by the several members of the Biological Survey collectively was 
only about a month (Aug. 12 — Sept. 15, 1896), it cannot be as- 
sumed that all the mammals of the region were secured. Sixty-one 
species are included in the accompanying list, most of which were 
obtained in good series, the total number of specimens collected and 
brought back to our National Museum being about 450. 
My assistants who took part in this work were Vernon Bailey, 
Chief Field Naturalist of the Biological Survey, and Edward A. 
Preble and Cleveland Allen, assistants. The localities at which col- 
lections were made are: Williamson river, near the road crossing; 
Fort Klamath; Anna Creek Canyon and Pole Bridge Creek; Crater 
Lake near end of road; Glacier Peak and Llao Rock; Diamond 
Lake; the upper or western Sink Creek (at the east base of the 
range on the road from Diamond Lake to Klamath Marsh); and 
Prospect, in the upper Rogue river valley, on the west slope of 
Mount Mazama. 
In addition to the specimens above mentioned, I had many 
years previously (in 18^3-84) received as a gift from the late Major 
Charles E. Bendire a small collection made by him at Fort Klamath. 
This collection contained several new species, of which Spermophi- 
lus chrysodeirus and Atophyrax bendirei were described by me. 
Subsequently Dr. J. C. Merrill presented me with a few additional 
specimens, including the chipmunk described as Tamias amoenus
