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

 small, keeled ; a more or less distinct A-shaped series of enlarged

 well-developed, but shorter, appendage. Male with a small nuchal 

 crest. Dorsal scales smaller than ventrals, smooth or very feebly 

 keeled; on each side of the back a series of small subcorneal distant 

 scales. The fore limb stretched forwards extends beyond the tip of 

 the snout ; the adpressed hind limb reaches the axil or nearly so far. 

 Greyish above, marbled with reddish brown, with a few equidistant 

 angular transverse dark markings, the anterior of which encloses the 

 black interorbital spot ; wing-membranes above dark brown with 

 lighter lines, inferiorly immaculate or with a few scattered black
