THE MOUNTAIN BAT.f 
This species is an example of a small series of Eats which, although nearly allied to the preceding, 
are inhabitants of the Eastern hemisphere, the known species of the genus Emballonura being 
found in the Eastern Archipelago and Australia, and of some of the oceanic islands of the great 
Pacific. The ears in this genus are somewhat triangular in form, with the outer margin sinuated ; 
THE MOUNTAIN HAT. 
the tragus is truncated, slightly widened at the tip, and furnished with a small blunt projection at 
the base of the outer margin ; the muzzle is somewhat elongated, with curved nostrils situated in a 
rounded pit ; the interfemoral membrane is large, and stretched by long spurs. There are four incisor 
teeth in pairs above, and six below, and two pre-molars and three molars on each side in each jaw. 
The Mountain Bat ( Emballonura monticola) is a very small creature, measuring only an inch and 
a half in length, with a tail nearly half an inch long, the extremity of which protrudes from the back of 
the interfemoral membrane. The wing-membrane springs from the ankle. The general colour of the 
fur is a cliocolate-brown, lighter on the lower surface, the hairs being in all parts chocolate-brown at 
the tips. Their basal portions are yellowish -white on the back and brown on the belly. The mem- 
branes are entirely naked. 
This Bat is an inhabitant of Java, Sumatra, Borneo, and the Philippine Islands, where it lives in 
the -wildest and most solitary regions of the mountains. It is social in its habits, considerable troops
