The Roussette[W] and the Rougette[X] seem to form two distinct species, but they so nearly resemble each other that they ought not to be presented apart, as they differ only in the size of the body and colour of the hair. The Great Ternat, (_fig. 117._) whose hair is of a reddish brown, is nine inches in length, from the tip of the nose to the insertion of the tail, and in breadth three feet, when the membranes, which serve it for wings, are fully extended. The Rougette, whose hair is of a reddish ash colour, is hardly more than five inches and a half in length, and two feet in breadth, when the wings are extended; and its neck is half encircled with a stripe of lively red, intermixed with orange, of which we perceive no vestige on the neck of the roussette. They both belong to nearly the same hot climates of the old continent, are met with in Madagascar, in the island of Bourbon, in Ternat, the Philippines, and other islands of the Indian Archipelago, where they seem to be more common than on the neighbouring continents. [Footnote W: Also called the Flying Dog, and the Great Bat of Madagascar.] [Footnote X: Or the Red-necked Flying Dog.] In the hot countries of the New World, there is another flying quadruped, of which we know not the American name, but shall call it Vampyre, because it sucks the blood of men, and other animals while asleep, without causing sufficient pain to awaken them. This American animal is of a different species from the bats just mentioned, both of which are to be found solely in Africa, and in the southern parts of Asia. _Engraved for Barr's Buffon._ [Illustration: FIG. 117. _Ternat Bat._] [Illustration: FIG. 118. _Bull Dog Bat_] [Illustration: FIG: 119. _Senegal Bat_]
