24. Chamaeleon damaranus. (Plate XL. fig. 3.) 



Casque similar to that of C. pumilits, but more produced pos- 

 teriorly ; the distance between the commissure of the mouth and 

 the extremity of the casque exceeds the length of the mouth ; a 

 dermal lobe connects the occipital process with the back ; labials 

 com])aratively large, 10 or 11 to below the centre of the eye. 

 Scales on back and sides very small and smooth, with enlarged 

 roundish or oval smooth tubercles, forming two longitudinal series 

 on each side, the upper of which is not far distant from the dorsal 

 crest ; latter very feeble, the tubercles being very blunt ; ventral 

 scales subequal, no ventral crest ; throat with enlarged flat tubercles ; 

 a series of very large, fringed scaly lobules along the throat, the 

 anterior roundish, as broad as long, and overlapping. No tarsal 

 process. Tail considerably longer than head and body, with nume- 

 rous large tubercles, the largest of which equal those on the side of 

 the back.
