Head small ; snout short, as long as, or scarcely longer than, the 

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

 naked, smaller than the eye-opening. Upper head-scales very un- 

 equal, strongly keeled ; a more or less distinct A-shaped series of 

 enlarged scales on the forehead ; a small subeonical tubercle at the 

 posterior corner of the orbit ; seven to ten upper labials, the last 

 twice or thrice as large as the preceding. The male's gular appendage 

 longer than the head. Male with a small nuchal crest. Dorsal 

 scales irregular, keeled, the largest at least twice as large as the 

 ventrals; 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 the elbow of 

 the adpressed fore limJp or not quite so far. Upper surfaces metallic, 

 with small dark spots and undulated cross bands; a black spot between 

 the orbits and another on the nape ; wing-membranes orange, with 

 black marblings or irregular cross bands; throat speckled with 

 black ; gular appendage orange in the male, bluish in the female.
