PTEROPUS ROSTUATUS. 
slightly curved, with a very small distension at the hase. The grinders are very 
narrow : the two anterior teeth having an elevated point, which is obliquely trun- 
cated, while the posterior teeth are low, with an even surface, much worn by 
trituration- In the lower jaw the front teeth have the same form and disposition as 
in the upper. The canine teeth are equally long, slender, and curved. The first 
grinder is very minute, and placed in contact with the canine tooth ; after a consi- 
derable vacancy, follows the second grinder, which is elevated, and obliquely trun- 
cated above ; the third has a similar form, but is less projecting ; the fourth, fifth, 
and sixth are greatly compressed, and resemble the third, fourth, and fifth in the 
upper jaw. There is a small difference in the disposition of the grinders in the 
upper and in the lower jaw : in the former the series is perfectly regular ; in the 
latter a slight contraction takes place near the canine tooth, posterior to which the 
series has a more evident lateral tendency. 
The eyes, as in other species of Pteropus, are large and prominent ; the pupil 
is circular, and the iris dark* The ears consist of a simple auricle, which is oblong, 
rounded, and half an inch in length. The body, both above and underneath, the 
arms, the neck, head, and face are covered with exquisitely fine, short, silky hairs, 
very soft to the touch, of a brown colour, with a tint of Isabella yellow, inclining 
to gray. In some of the specimens the under parts have a lighter grayish hue. On 
the anterior part of the back, on the breasts, and on the extremity of the body near 
the vent, the hairs are longer, and delicately woolly ; they gradually decrease in 
length from the forehead to the nose, and towards the hands and legs. As the 
colour is more intense at the extremity of the separate hairs, different shades of 
brown and yellowish gray are exhibited, according to the accidental undulations 
which exist on the surface. 
The Pteropus rostratus, or Lowo-a&su of the Javanese, is far less abundant 
than the Pteropus javanicus, or Kahng; but it still exists in sufficient numbers to 
commit serious injury among the plantations and fruit-trees. Like other species of 
Pteropus, it feeds on fruits of every description, but particularly infests the various 
species of Eugenia or Jambu, which are cultivated in gardens. During the day 
it remains suspended under branches of trees, or it retires under roofs of old 
houses and sheds. At night it sallies forth, like other species of Pteropus,
