on the sides of the head. In Myopteris they are similar, 
but larger, and the muzzle is short and blunt. In the other 
genera, they are very close together, and folded down on 
the front of the head, as in Nyctinomus , 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. Thy - 
roptera 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 all 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; 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 usu¬ 
ally 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 Macro - 
glosses 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.
