ledges on the ill-defined runways of Hvotomys. Everywhere 
they were found to be quite active during the day, except during 
midday in clear weather. 
The large series of S. p. streatori is remarkably uniform in 
coloration, proportions and skull characters, and is practically 
indistinguishable from a large series from southeastern Alaska. 
Localities: Cordova 16; Cordova Bay 6; Ellamar 4; Valdez 
Narrows 6; Port Nell Juan 8; Hawkins Island 6; Hinchinbrook 
Island 11; Latouche Island 14; Hoodoo Island 13; Elrington

Sorex obscurus alascensis Merriam. Alaska Dusky Shrew. 
This is the most generally distributed species of mammal in 
the region and the only species of shrew found on the more 
isolated Montague, Green, Knight, Dise, and Eleanor islands. 
The series of ninety-two specimens in the collection was secured 
at seventeen localities. This series is fairly uniform. Some local 
variation is apparent, as on Montague Island where the species 
is somewhat more robust with a very slight increase in foot and 
tail measurements. No skull differences have been detected in 
the series from the various islands.

Myotis lucifugus (LeConte). Little Brown Bat. 
One specimen secured, an adult male, at Port Nell Juan. 
This is an alcoholic specimen and agrees well with lucifugus in 
ear characters and body measurements. Several others were 
seen about the Port, but they appeared so late in the evening 
that it was not possible to see distinctly enough to shoot them. 
One was also noted on Hoodoo Island. Wherever found they 
were very local and invariably solitary. If once located they 
could be found at the same spot each evening, flitting about 
catching insects.
