the anterior surface of the arm and forearm, and upon the inferior 

 surface of the thigh and leg, properly so called. The tail is a little 

 shorter than the body and head together; its upper surface is covered 

 with small, smooth, imbricated, posteriorly rounded scales; whilst its 

 inferior surface is protected by a central series of transversely elon- 

 gated plates or scutellae, more developed in the male than in the 

 female. The sides of that organ are sharp, though not otherwise 

 serrated or denticulated. 



The color is sometimes greyish ; at others, yellowish-brown, and, as 

 usual, of a much lighter hue beneath than above. Pale dots may be 

 seen indiscriminately scattered all over, though, generally speaking, 

 more apparent upon the neck and anterior portion of the body ; in 

 very young specimens, these dots are apparently wanting, but the 

 upper surface of the tail exhibits pale, transverse, narrow streaks.
