lobed, slightly less in length than free edge of interfemoral membrane. 
Length of foot about half that of tibia. Tail exceeds forearm in 
length by from 2 to 10 millimeters. All membranes relatively thin 
and delicate. 
Pelage.—F ur everywhere full and soft, longest on middle portion 
of back, where it reaches a maximum length of 11 millimeters. Face 
naked save for occasional long hairs rising from the glandular masses, 
and a fringe of shorter finer hairs extending downward along sides 
of upper lip. Fur reaches onto dorsal base of ear for a distance of 
2 or 3 millimeters. Wings and interfemoral membrane naked except 
at their extreme bases.

Description; status of subspecies; list of localities. 
Diagnosis —Color wood brown; total length, 92 to 101 millimeters, 
averaging 97.2. 
Description: Color—Dorsal surface wood brown, becoming paler 
about head; hairs with faintly defined light plumbeous bases. Ventral 
surface vinaceous buff; membranes a slightly darker shade of same 
color. G. M. Allen (1916, p. 342) discusses color variation in C. r. 
pallescens and records minutely the shading of two ‘‘reddish’’ indi- 
viduals (10694, 10695, Mus. Vert. Zool.) secured in a mine at River- 
side Mountain on the Colorado desert. J. Grinnell had earlier stated 
(1914, p. 263) that the reddish east of these two specimens ‘‘is doubt- 
less wholly adventitious, due to the fine, sticky red dust with which 
the walls of the mine were covered.”’
