the thumb, fifth finger, and fore arm, like the fur on the under side 
of the wing-membranes. On the middle of the back the individ- 
ual hairs are colored as follows: deep plumbeous at base, light 
yellowish brown (shading to umber towards apex) through middle 
half, umber-brown near apex, silvery white at tip. 
But little has been recorded of the habits of this bat. It isa 
strikingly large and handsome species, but seems to be nowhere 
abundant. There are probably two to four young, for females with 
all four mammee used have been taken. In the northern part of its 
range it migrates south in winter.

The length of the fore arm is 1.3=1. 65 in. (34-38 
mm.). The ears (Fig. 12) are thick and leathery. 
The tragus is short, blunt, and broad, and is bent 
slightly forward. 
The fur is everywhere plumbeous at extreme 
Fig. 12. Earofp base. The remainder of the hair varies from burnt 
Ganecve’s Pat. umber to mummy-brown over the back, and from 
raw umber to hair-brown below. There are occa- 
sionally other variations in color. 
This species is not rare in this county. It seems to be somewhat 
less likely to be found around towns than some other species of bats.
