Myotis lucifugus alascensis Miller 
Alaska Brown Bat 
Myotis lucifugus alascensis Miller (1897b, pp. 63-64). Original deserip- 
tion; type from Sitka, Alaska. 
Diagnosis —Similar to Myotis lucifugus altipetens, but color 
darker; general color of fur on back mummy brown. 
Description.—Feet, ears, and membranes chaetura black, as also 
the bases of the hairs everywhere. Terminal portion of fur on back 
mummy brown; on ventral surface tips of hairs drab. Fur on middle 
of back 6 to 7 millimeters in length. (For comparisons between this 
and other nearly related races see under Myotis lucifugus altipetens, 
p. 266.) 
Measurements—The single example at hand from California 
measures in millimeters as follows: total length, 86.0; tail vertebrate, 
39.0; foot, 9.0; forearm, 35.0; tibia, 15.0; greatest length of skull, 14.9. 
Synonymy and History—The Alaska brown bat was deseribed by 
Miller (1897), pp. 63-64), who examined sixteen speeimens, thirteen 
being from Alaska, and the remaining three from Queen Charlotte 
Islands, British Columbia. The type specimen was procured at 
Sitka, Alaska. 
Distribution —Miller (1912, p. 55) gives the range of Myotis luci- 
fugus alascensis as the humid coast district of southern Alaska and 
northern British Columbia. The specimen now at hand from Cali- 
fornia is an adult male (no. 11843, Mus. Vert. Zool.), taken at Eureka, 
Humboldt County, August 2, 1910 (see map, text-fig H). I can 
find no previous record of this race from California. 
Natural History.—Nothing is known of the habits of this bat in 
California.
