is sparsely furred. The rest of the inemhraiie is naked except 
the inferior border of the wing membrane wliere a delicate fringe 
of hair is seen. The remainder of the ventral aspect is much 
darker (with tawny brownish shades prevailing) than on the back ; 
the hair toward the side of the trunk (mammary line) is much 
longer and deeper in shade than elsewhere. The hair is uni- 
colored. It extends in an abruptly defined, sparse layer on the 
wing membrane as far as the end of the flesliy ])art of the forearm 
and to the wing membrane just beneath it and thence obliquely 
downward and inward to the knee. 
The dorsal aspect of the interfemoral membrane, the thighs, and 
legs are covered with hair. This is sparse over tlie limbs, but 
better developed over the membrane, especially at the middle 
tliird.^ The under surface is nearly naked but the thighs are 
thickly furred in a manner unusual in the family. The abruptly 
bent metacarpal bone of the second digit is the most striking char- 
acter in the skeleton. The penis is not j)endant but directed 
upward parallel to the abdomen. The prepuce is half withdrawn 
from a subconic.'d glans.
