98 Mammals of Eastern Asia 
(meaning "folded," in allusion to the ears) is an allied, perhaps 
not very different species. Its forearm measures 2 inches. The 
color is also dark brown. This latter Bat, which hides in caves 
and deserted buildings, was described first from Java. It has 
been reported since from Bengal and Hainan. 
The Egyptian Wrinkled-lipped Bat, Nyctinomus tceniotis 
("banded-ear," relating to the stiffening bands of cartilage in 
the conch of the ear), is a species of wide range in the Old 
World tropics. The length of the forearm is 2% to 2% inches. 
Originally collected in Egypt, it is represented in Fukien and 
Yunnan by the form insignis. Satunin indicates that another 
race, latouchei, reaches Korea and Vladivostok. 
MOUSE-TAILED BATS (FAMILY RHINOPOMID^) 
This is another very small family containing the single genus 
Rhinopoma. Its mixture of specialized and residual characters 
proves that it has developed, separated from the remaining 
Microchiroptera, for an extremely long period of time. 
It differs from all other living insectivorous Bats by retaining 
two joints of the index finger in the wing, though unlike the 
majority of the Fruit Bats, it has lost the claw and terminal 
joint. It also differs by possessing a mouse-like tail almost as 
long as the head and body while the inter femoral membrane is 
so short that it extends down the tail little more than % inch. 
Rhinopoma has gone much farther in dental reduction and spe- 
cialization than have some of the primitive Vespertilionid Bats 
such as My otis. The free tail and the shortness of the inter- 
femoral membrane may actually be a secondary condition. A 
similar type of tail occurs in the Fruit Bat Notopteris. 
There is a small, low, rounded noseleaf, and the ears are 
ample, short, round-pointed, and joined together by a deep band 
of skin across the forehead. The nostrils appear as forwardly 
opening slits. The broadening of the rostrum of the skull is
