Distribution and habitat. The humid coast region from southern 

 Alaska to northern California (fig. 93). One skin from Fremont, 

 Oreg., is referred to this species by Miller and Allen, but is paler 

 than typical specimens and approaches clirysonotus, while 1 from 

 McKenzie Bridge and 2 from Tillamook County, are dark and rich 

 in color and near typical evotis. In the Jewett collection are 2 fe- 

 males from Salem, collected by Elmer Griepentrog on June 5 and 

 August 13, 1927, and in the 

 University of Oregon col- 

 lection are 1 from Eugene 

 collected in the fall of 



1919, 1 from McKenzie 

 Bridge taken July 4, 1914, 

 and 1 from Fish Lake, 

 Jackson County, July 30, 



1920. In the Alex Walker 

 collection are an adult 

 female taken at Blaine, 

 August 10, 1921, and an 

 adult male from Tilla- 

 mook, September 8, 1924.

just over the Washington 



line at Godman Spring, Columbia County, are mainly intermediate 



bub are referred by Miller and Allen to evotis. 



While at present represented in Oregon by only a few specimens, 

 the species may be expected over all of the Transition Zone area 

 around and west of the Cascades, but in no great numbers. The 

 specimens referred to this dark form were collected by Luther J. 

 Goldman, one at 5,000 feet altitude on O'Leary Peak, 10 miles south 

 of McKenzie Bridge, on July 2, 1914; another collected the same date 

 at McKenzie Bridge by Charles Sheltoii ; another taken by Goldman 

 August 23 at Fremont, in the eastern foothills of the Cascades ; and 

 two taken by Alex Walker at Tillamook, August 10, 1921, and 

 Blaine, September 8, 1924. 



General habits. Most of the specimens taken were shot in the 

 evening twilight as they flew rapidly along the edge of the forest or 

 over open meadows near the tall timber. There is little known of 

 the actual habits of these bats, either where they spend the day or 

 where they go for the winter hibernation.
