In all its movements and attitudes, the action of the _Pteropus_ is highly interesting. If placed upon the ground, it is almost helpless, none of its limbs being calculated for progressive motion; it drags itself along by means of the hook attached to each of its extended thumbs, pushing at the same time with those of its hind feet. Its natural position is exclusively pensile; it moves laterally from branch to branch with great ease, by using each foot alternately, and climbs, when necessary, by means of its claws. When at rest, or asleep, the disposition of the limbs is most curious. At such times it suspends itself by one foot only, bringing the other close to its side, and thus it is enabled to wrap itself in the ample folds of its wings, which envelop it like a mantle, leaving only its upturned head uncovered. Its fur is thus protected from damp and rain, and to some extent its body is sheltered from the sun. As it collects its food by means of its mouth, either when on the wing, or when suspended within reach of it, the flying-fox is always more or less liable to have the spoil wrested from it by its intrusive companions, before it can make good its way to some secure retreat in which to devour it unmolested. In such conflicts they bite viciously, tear each other with their hooks, and scream incessantly, till, taking to flight, the persecuted one reaches some place of safety, where he hangs by one foot, and grasping the fruit he has secured in the claws and opposable thumb of the other, he hastily reduces it to lumps, with which he stuffs his cheek pouches till they become distended like those of a monkey; then suspended in safety, he commences to chew and suck the pieces, rejecting the refuse with his tongue. To drink, which it does by lapping, the _Pteropus_ suspends itself head downwards from a branch above the water. Insects, caterpillars, birds' eggs, and young birds are devoured by them; and the Singhalese say that the flying-fox will even attack a tree snake. It is killed by the natives for the sake of its flesh, which, I have been told by a gentleman who has eaten of it, resembles that of the hare.[1] It is strongly attracted to the coconut trees during the period when toddy is drawn for distillation, and exhibits, it is said, at such times, symptoms resembling intoxication. [Footnote 1: In Western India the native Portuguese eat the flying-fox, and pronounce it delicate, and far from disagreeable in flavour.] Neither the flying-fox, nor any other bat that I know of in Ceylon, ever hybernates. There are several varieties (one of them peculiar to the island) of the horse-shoe-headed _Rhinolophus_, with the strange leaf-like appendage erected on the extremity of the nose. It has been suggested that the insectivorous bats, though nocturnal, are deficient in that keen vision characteristic of animals which take their prey by night. [Illustration: RINOLOPHUS.]
