bat. The border of the ear is light brown, and there is no pes ue of 
hair on the back of the fore arm. 
On the back, neck, and head, the base of the hairs is reddish 
black abruptly changing to pinkish buff, and this in turn shading to 
bright chestnut. The tips of the longer hairs are white. The hairs 
on the posterior three-fourths of the interfemoral membrane lack the 
black at the base, otherwise they resemble those on the back. To- 
ward the face the darker 
tips of the shorter hairs dis- 
appear, the general color 
being a light buff. There 
is a tuft of white hairs at 
the base of the thumb and 
along the base of the fourth 
finger. At the side of the neck the white tips of the hairs are so 
long that they form a white patch. The white tips are also rather 
more conspicuous over the throat than over the most of the body. 
The breast, the belly, and adjacent parts of the wing-membrane 
are a pale fawn-color. 
According to Merriam* this species flies earlier in the evening 
than other bats do, and has even been seen flying in a cloudy after- 
noon. It is often taken here in the early evening within the city 
limits, especially in the early summer when encumbered with its 
young. It is frequently found attached to twigs of trees and 
shrubs, and in that position very closely résembles a dead leaf—an 
interesting example of protective mimicry. 
The red bat and the hoary bat differ from all other bats in this 
vicinity in having four mamme instead of two. The young are 
produced in May or June, and are two to four in number. They 
are nursed for some time, and are found clinging to the mother when 
they are at least half grown. I have never found more than two 
that were over one-fourth grown attached at the same time, how- 
ever, though a female with a single half-grown one attached is very 
common. It is difficult to imagine how the mother could carry her 
whole family at once when they reach that size. The mothers show 
considerable attachment for their young, and if separated from them 
and frightened away are almost sure to return to look for them. 
I have kept the young of the red bat in captivity for some weeks
