Synonymy and History—The northwestern long-legged bat was 
described by True (1886, p. 588) under the name Vespertilio longi- 
crus, from a specimen obtained at Puget Sound. 
Distribution.—The California range of Myotis longicrus longicrus 
cannot be confidently stated without much further field work. As 
will be noted from the list of verified localities, this bat appears 
to be restricted to the Transition and Upper Sonoran zones in the 
humid coast belt south as far as Pescadero Creek, San Mateo County, 
and in the northern portion of the Sierra Nevada, south at least to 
Walker Lake, Mono County (see map, text-fig. I). The range of 
Myotis ‘‘lucifugus’’ longicrus as given by Miller (1912, p. 55) and 
J. Grinnell (1913), p. 276) includes that of the newly recognized 
Myotis longicrus interior. 
Specimens Examined—The writer has examined 14 specimens 
from the following loealities in California: Mendocino County: Mt. 
Sanhedrin, 1 (Acad. Nat. Sci. Phila.) ; Sherwood, 2; Sonoma County : 
near Guerneville, 2; near Cazadero, 1; Nevada County : Independence 
Lake, 1; Placer County: Dutch Flat, 1; Eldorado County: Fyffe, 
3; Mono County: Walker Lake, 1; San Mateo County: Menlo Park, 1; 
Pescadero Creek, 1.
