262 AGAMID^. 



Head larger than in D. volans ; snout longer than the diameter 

 of the orbit ; nostril lateral, directed outwards ; tympanum naked, 

 as large as the eye-opening. Upper head-scales very unequal, 

 rather large, keeled ; a small conical tubercle at the posterior corner 

 of the orbit ; nine upper labials, the last twice as large as the pre- 

 ceding. A slight nuchal crest. Dorsal scales larger than ventrals, 

 smooth, except a series of strongly enlarged scales running along 

 each side of the vertebral line ; these large scales, the keels of which 

 form two continuous lines, are separated by a row of small smooth 

 scales ; on each side of the back a series of enlarged keeled 

 distant scales. The fore limb stretched forwards extends beyond 

 the tip of the snout ; the adpressed hind limb reaches midway 

 between the elbow of the adpressed fore limb and the axil. Grey- 

 brown above, with metallic gloss and irregular darker markings ; 

 wing-membranes rather indistinctly blackish^marbled above, with 

 a few black spots inferiorly.

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 supraciliary region ; seven to eleven upper 

 labials. The male's gular appendage very large, always much longer 

 than, and frequently twice as long as, the head ; female also with a 

 well-developed but smaller gular sac. Male with a very smaU nuchal 

 crest. Dorsal scales little larger than t.he 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 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, inferiorly immaculate or with a few black spots ; a blue 

 spot on each side the base of the gular appendage.
