BATS FROM MOUNT WHITNEY, CALIFORNIA 
By Glover M. Allen 
In July, 1915, it was the writer’s privilege to accompany Prof. Theo- 
dore Lyman on a brief expedition to Mount Whitney, the highest peak 
in the United States outside of Alaska, lying near the southern end of 
the Sierra Nevada of California. Starting from Lone Pine, at the 
eastern foot, we ascended to the upper limit of timber and there 
camped for a week or more by the outlet of a mountain lake, at an alti- 
tude of about 11,000 feet. In successive evenings, four species of 
bats were secured at this camp, one of which proves to be an unsus- 
pected new species, apparently related to Myotis lucifugus. The fol- 
lowing brief notes are further offered as amplifying slightly the dis- 
tributional data lately published by Mrs. Hilda W. Grinnell in her 
excellent Synopsis of the Bats of California (Univ. of Calif. PubL, 
zooL, 1918, vol. 17, p. 223-404, pi. 14-24). All the specimens obtained 
were, through Doctor Lyman’s generosity, given to the Museum of 
Comparative Zoology, at Cambridge, to the authorities of which I am 
indebted for permission to publish this report. 
Myotis yumanensis sociabilis H. W. Grinnell 
TEJON BAT 
This form of the Yuma bat is characterized by Mrs. Grinnell as 
intermediate in color between typical yumanensis and its subspecies 
saturatus. She indicates its range as the ‘‘semi-arid Transition and 
Sonoran zones in [southern] California west and north of the south- 
eastern deserts.” On July 16, a bat which seems referable to this 
race was shot just above our camp at 11,000 feet on Mount Whitney,
