Draco maculatus

Description

Head small; snout a little longer than the diameter of the orbit; nostril lateral, directed outwards; tympanum scaly. Upper head-scales unequal, strongly keeled; a compressed prominent scale on the posterior part of the superciliary region; 7 to 11 upper labials. The male's gular appendage very large, always much longer than the head, and frequently twice as long; female also with a well-developed but smaller gular sac. Male with a very small nuchal crest. Dorsal scales but little larger than the ventrals, irregular, smooth or very feebly keeled; on each side of the back a series of large trihedral keeled distant scales. The fore limb stretched forwards reaches beyond the tip of the snout; the adpressed hind limb reaches a little beyond the elbow of the adpressed fore limb, or to the axilla. Greyish above, with more or less distinct darker markings; a more or less distinct darker interorbital spot; wing-membranes above with numerous small round black spots, which are seldom confluent, beneath immaculate or with a few black spots; a blue spot on each side of the base of the gular appendage.

From snout to vent length, 82 mm; tail, 115 mm.
