covered with scales similar to those of the fingers : the inner or first 

 toe is the smallest ; the second is the next in length ; the third and 

 fifth are nearly equal sized, whilst the fourth is the longest. 



The upper regions are olive-brown, interspersed with numerous 

 small, black, and irregular spots, extending equally to the upper sur- 

 face and sides of the head, and over the limbs to the very tip of the 

 fingers and toes. A subcircular, jet-black spot, may be observed at the 

 shoulders. The inferior regions are generally unicolor, of a whitish- 

 yellow hue ; sometimes small, blackish spots, may be seen under the 

 neck and abdomen. 



Loc. Specimens of this species were collected among the sandhills, 

 on the coast of Patagonia, where they abound. A sketch of the color- 

 ation, from life, was made at that place by Mr. Drayton.
