covered with whorls of smooth, narrow, and transversely 

 convex scales. A series of from ten to twelve femoral 

 pores along each thigh. 



The ground color is smoke gray or cinnamon, with 

 numerous irregular maculations of dark brown or black. 

 These markings are much smaller and less numerous on 

 the lower surfaces. There is considerable variation in 

 the color pattern. One specimen has two narrow paral-

 unmarked, but the rest of the upper surface is irregu- 

 larly spotted. Other specimens offer an almost perfect 

 imitation of coarse granitic rock.
