genus of the lizard family Agamidae. Members of the genus are commonly referred to as flying lizards, because scaly membranes between the forelegs and hindlegs allow them to glide from tree to tree. There are more than 40 species of Draco. Most species are small, with a snout-vent length less than 8 cm (about 3 inches), and occur in the forests of Southeast Asia and the East Indies.
