222 Gen. Hardwicke and Mr. Gray 



poris femoralihus nullis ; corporis et membrorum lateribus fim- 

 briatis. 



This geniis can be confounded only with the Uroplates of 

 Daudin, from which it may immediately be distinguished by the 

 toes being completely webbed, by the scales of their under side 

 being broader towards the extremities, and entire, and by the 

 last joint, which bears the claw, being raised up and exposed, while 

 in the Uroplates it is inclosed in the groove of the scales, and com- 

 pletely hid from view ; indeed the formation of the toes is similar 

 to that of the Platydactyles and Geckos^ but it differs from them 

 in their being webbed, and in the membranes on the sides of the 

 body, which appear to indicate very different habits.

Head and body depressed ; above pale brown, with irregular 

 shaped dark spots, with a darker margin on each side of the body 

 just above the lateral fringe, two round spots on the back of the 

 neck, two sub-quadrangular larger spots over the shoulders, and four 

 irregular wavy bands at nearly equal distance from one another; 

 the scales of the upper part of the body are small and even, those 

 of the upper side of the limbs and tail and lower part of the body 

 are rather larger ; the labial scales are very large, and the central 

 one of the upper jaw is broad, and furnished with one large 

 central and two smaller ones on its upper edge. The sides of the 

 head, betv/een the angle of the mouth and the ear, just behind the 

 ear, the front and hinder edge of the fore legs, the side of the 

 body, from the fore to the hind legs, the bend of the outer and 

 the whole of the inner edge of the hind legs, are furnished with a 

 membranaceous fringe, which is covered with rather large, broad, 

 quadrangular scales, placed in cross bands on the upper side, naked 

 and smooth beneath, except the fringe on the side of the head, 

 which is covered with reticulated scales above, and smaller ones 

 beneath. Tail depressed, edge slightly expanded.
