breathing heavily until killed for the purpose of preserving 
it. Mr. Blanchard states that he has frequently found 
bats in tunnels and that the tunnels in which they are found 
are always dry, that he has never found them in wet 
ones. The temperature at this point was 46° F. This is 
the only record of which I have any knowledge of the 
occurrence in winter or hibernation of bats in Colorado. 
These two specimens are now in the Museum of the State 
University, of which Mr. Henderson is Curator and it is by 
his permission that I am permitted to publish these notes. 
Myotis californicus ciliolabrum (Lat. cilia, eyelash, thence 
hair + labrum, lip). Hairy-Lipped Bat. 
Vespertilio ciliolabrum Merriam, Proc. Biol. Soc. Wash., iv., p. i 
(1886). 
Type locality. — Trego County, Kansas. 
Measurements. — Total length, 3.00 ; tail vert., 1.4; hind foot, 0.3 ; 
forearm, 1.30. 
Description. — (From a specimen taken near Sunny Peak, Routt 
County, Colorado, Aug. 28, 1906): Basal portion of interfemoral 
membrane thinly haired; color above very pale yellowish brown 
(Miller calls it pale yellowish white) ; below pale whitish gray. All 
hairs plumbeous at base. Ears and membranes blackish. The 
pale color is the only character which distinguishes this form from 
M. californicus ; next to ill. yumanensis it is the palest of the Colo- 
rado species of Myotis. 
Distribution. — The distribution of this subspecies is not very 
well known. Its range seemingly extends from Trego County, 
Kansas, and central South Dakota westward. In Colorado Cary 
took it a few miles southeast of Sunny Peak, in Routt County. 
Myotes subulatus (Lat. subula, awl; in zool., slender, more 
or less cylindrical and tapering to a point). Say's Bat. 
Vespertilio subulatus Say, Long's Expedition to the Rocky Moun- 
tains, ii., p. 65, footnote (1823). 
Type locality. — Arkansas River, near La Junta, Colorado. 
Measurements. — Total length, 3.25; tail vert., 1.50; hind foot, 
0.30 ; forearm, 1.35.
