PLATE 15 
Figs. +, 5, 6. Photographs of a living lump-nosed bat (Corynorhinus rafi- 
nesqua pallescens, no. 21435, g), secured in a cave near Whitewater, Riverside 
County. 1.00. Fig. 4 shows the bat in a dormant state, with wings held 
close to the body and ears folded back under them. The pinnae here are 
not bent sharply back, but curved by a regular and even crimping of the 
posterior edges of the auricles, the resulting appearance reminding the observer 
of the curving horns of a mountain sheep. Fig. 5 was taken when the animal 
had been disturbed and seemed to be endeavoring to overcome the lethargy 
of profound slumber. Fig. 6 shows the bat fully aroused and about to take 
flight. The successive positions of the ears illustrate the way in which they 
are unfurled.
