with membranaceous ridges. The third group consists of those genera 
which have the thick end of their tails produced beyond the short trans¬ 
versely folded interfemoral membrane; they have a large thumb, which 
is usually swollen beneath. The ears of Cheiromeles are small, and on 
the sides of the head. In Myopteris they are similar, but larger, and the 
muzzle is short and blunt. In the other genera, the ears are very close 
together, and folded down on the front of the head, as in Nyetinomus , 
which has the muzzle obliquely truncate, and the lips large and trans¬ 
versely ridged; and Molossus , which has the face conical, the nose 
rounded at the end, and the lips swollen. Thyroptera chiefly differs, 
from the latter in having a large round pad on the middle joint of the 
thumb. The genus Diclidurus, from Brazil, differs from the preceding 
in the tail being very short, many jointed, and inclosed in a two-valved 
sheath placed at the base of the extended interfemoral membrane. 
The last tribe of Simple-nosed Bats ( Pteropina ) are peculiar for 
living almost entirely on fruit. They are characterized by having 
bluntly tubercular grinders, and the end of the fore finger furnished with 
a claw T ; they have a simple nose, with rather tubular nostrils placed on 
the sides of the muzzle ; their thumb is long and webbed at the base ; 
the interfemoral membrane is short, and they have only a very short 
tail, or none. They are found only in the warm parts of the Old World 
and the Australian Islands, where they are usually called Flying Foxes. 
They are divided into genera according to the form of the head, the 
position of the wings, and the length of the tongue. The Pteropi have 
a conical head, and are of a large size; the Cynopteri have a short thick 
head; the Epomophori a large head, and tufts of white hair on or near 
the head; the Macroglossce a long muzzle, and very long slender tongue, 
Harpyia and Cephalotis have heads like the Cynopteri , but the wings 
arise from the middle of the back ; the latter wants the claw on the end 
of the index finger.
