NOTES ON SOME BATS FROM ALASKA AND 
BRITISH COLUMBIA 
BY 
HILDA WOOD GRINNELL 
(Contribution from the Museum of Vertebrate Zoology of the University of California) 
The following notes seem worthy of publication as being contribu- 
tory to the very meager knowledge so far available in regard to the 
bats of Alaska and British Columbia. Specimens from these regions 
are very slow to accumulate; as they do become more plentiful it is 
inevitable that previous views in regard to identity and relationships 
of the species represented be more or less modified. 
Myotis longicrus longicrus (True) 
Among the twelve specimens of bats listed from Admiralty and 
Baranof islands, Alaska, by Heller (1909, p. 264) under the name 
Myotis lucifugus alascensis, there is one which is clearly referable to 
the longicrus group. This specimen (4, no. 186, Mus. Vert. Zool.) was 
collected by C. Littlejohn at Mole Harbor, Admiralty Island, June 9, 
1907. It measures in millimeters: total length, 90.0; tail, 40.0; fore- 
arm (both defective) ; tibia, 18.0; foot, 9.0; greatest length of cranium, 
14.3; breadth of brain-ease, 7.5. In color this example is deep Vandyke 
brown both above and below, the hairs with tippings of cimnamon 
brown. The coloration of this specimen is almost identical with that 
of examples of longicrus taken in northwestern California. The 
characters of this individual throughout thus align it with Myotis 
longicrus longicrus.
