Lizards of this family are most abundant in the Indian and Australian regions, showing a great variation of form analogous to that of the preceding family. The perhaps most highly specialized Agamoid is the genus Draco, small winged Lizards from the East Indies (fig. 8). The Dragons are tree-lizards, and possess a peculiar additional apparatus for locomotion: the much- prolonged five or six hind ribs are connected by a broad expansive fold of the skin, the whole forming a subsemicircular wing on each side of the body, by which they are enabled to take long flying leaps from branch to branch, and which are laid backwards at the sides of the animal while it is sitting or merely running.
