1918] Grinnell: A Synopsis of the Bats of California 279 
Description.—A specimen (no. 11844, Mus. Vert. Zool.) taken by 
F. Stephens at Cuddeback, Humboldt County, California, September 
16, 1910, presents the following coloration: Back, nearest bister ; lower 
surface, drab, darkest on chin, throat and sides; membranes, chaetura 
black. Fur 6 to 7 millimeters long on middle of back. 
Measurements.—The above specified example measures: Total 
leneth, 84.0; tail vertebrae, 35.0; tibia, 14.1; foot, 8.0; forearm, 35.0; 
ereatest length of cranium, 13.9. 
Synonymy and History.—This species was described, under the 
name Myotis ywmanensis saturatus, by Miller (1897), p. 68). The 
type specimen was taken at Hamilton, Skagit County, Washington. 
Distribution—Myotis ywmanensis saturatus is the dark northwest 
coast form of the Yuma bat. Miller (1912, p. 56) gives the range 
of this race as the Transition Zone in Oregon, Washington, and British 
Columbia. Its distribution in California is given by J. Grinnell 
(19136, p. 277) as the Transition and Boreal zones in extreme north- 
western California, west to Cuddeback, Humboldt County, and east 
to Mount Shasta. The specimens upon which this statement of the 
Californian distribution of the Miller bat was based have been exam- 
ined by the present writer who finds that the examples from Mount 
Shasta are Myotis lucifugus altipetens, as are also the specimens from 
the same locality recorded under the name saturatus by C. H. Merriam 
(1899, p. 89). [See under Myotis lucifugus altipetens, p. 264.] This 
leaves Eureka and Cuddeback, in Humboldt County, the only verified 
record stations, within the state. This bat will probably be found to 
occur at many points within the extreme northwestern portion of 
California, where humid conditions prevail. (See map, text-fig. J.) 
Specimens Examined.—The writer has examined but two speci- 
mens of the Miller bat from within the state of California. They 
were taken at Eureka (no. 11854, Mus. Vert. Zool., August 2, 1910) 
and Cuddeback (see under Description, above), both localities being 
in Humboldt County. 
Natural History.—Nothing has been recorded concerning the 
natural history of Myotis ywmanensis saturatus as occurring in Cali- 
fornia.
