FRUIT-BATS.

The Short-Nosed Fruit-Bats. 
Genus Cynopterus. 
The short-nosed fruit-bats comprise several species almost exclusively confined 
to the Oriental region (that is to say, ranging from India to the Philippine Islands), 
and readily distinguished from the fox-bats by their short and rounded muzzles, 
marked by a shallow vertical groove, and their small size. The teeth are, moreover, 
somewhat less numerous than in the latter, being usually thirty-two, but occasion¬ 
ally, owing to the absence of one pair of lower incisors, only thirty. They have 
generally a short tail, with the same relations to the membrane between the legs as 
in the tailed fox-bats. 
The common short-nosed fruit-bat (Cynopterus marginatus), ranging from 
India to the Philippine Islands, is one of the best-known forms, and is remarkable 
for its extreme voracity. It is very common throughout India, where it generally 
inhabits trees,—especially the palmyra palm,—but is occasionally found in caverns 
and crevices of rocks. This bat is very destructive to fruit, being especially fond 
of plantains and mangoes. As an instance of its voracity, it may be mentioned 
that an individual, of which the weight when killed some hours after the feast was 
only one ounce, consumed two and a half ounces of plantains within a period of 
three hours. It has been observed that the flight of this species is much lighter 
than that of the fox-bats, although the general habits of the two groups are very 
similar. 
The Tube-Nosed Fruit-Bats. 
Genus Harpyia. 
Two curious bats, differing from one another considerably in size, and found 
from Celebes to New Guinea, North Australia, and New Ireland, are distinguished 
from the short-nosed fruit-bats by their still shorter and more rounded muzzles, 
but more especially by the production of the 
nostrils into a pair of long diverging tubes, 
reaching rather beyond the extremity of the 
muzzle. Such a structure, except to a less 
degree in one group of insect-eating bats, is 
quite unparalleled elsewhere in the whole 
class of Mammals, and gives to the creatures 
such an extraordinary appearance that it is 
difficult to believe at first sight that it is 
natural. So far as we are aware, no 
suggestion has been yet made as to the 
probable reason for this tubular prolongation of the nostrils, although it is, doubt¬ 
less, of some special advantage to these bats, of whose habits we have, indeed, 
practically no information. The tube-nosed fruit-bats are further distinguished by 
the small number of their teeth, of which the total is only twenty-four.
