Bull., 144:114, April 14, 1928. _Type._--Description based on a series of specimens, one of which came from Monterey, California. This locality was designated the type locality by Miller (1897: 78). _Racial character._--Color pale. _Measurements._--Two males and 2 specimens of unknown sex from the Blue Mountains, Columbia County, average: total length 87; length of tail 40; hind foot 7.5; ear 20; height of tragus 11; weight 5.4 grams. _Distribution._--The Blue Mountains area, of southeastern Washington; recorded from South Touchet (Miller and Allen, 1928: 116) and Godman Springs (W.

Specimens examined by me are much paler than _pacificus_ and most of them are indistinguishable from specimens of _evotis_ from California. =Myotis evotis pacificus= Dalquest _Vespertilio evotis_ Allen, Smithsonian Misc.
