scales; tlie back and upper part of the limbs are protected witli 

 large oval scales, each slightly elevated in the centre, and sepa- 

 rated from one another at tlie base by a series of minute granulated 

 scales. The tail, which is round at ihe base and slightly com- 

 pressed at the extremity, is covered with small irregular flat scales, 

 and is narrowed at equal distances into 16 — 18 ring-like con- 

 tractions, which are more visible in the centre, and gradually dis- 

 appear at each end. Each of these bands is furnished with a 

 scries of large orbicular subconical scales on the edge. The labial 

 scales, especially of the upper lip, are very long and narrow. The 

 edge of the eye-lid is reflexed and expanded ; femoral pores 

 8 — 9 on each side, in a triangular scries ; toes very short. 



Length of the auimal 7j inches ; of head and body 4 inches ; 

 tail 3{ inches.

This genus belongs to that group of the family which differs 

 from the type in the toes being destitute of those scales on the 

 underside which enable them to climb on perpendicular surfaces; 

 but it is known from the other genera of this section by the 

 peculiar form of the toes, which are arched at the end, that is to 

 say, the third joint is very short, and forms a right angle with 

 the second ; the fourth then goes off horizontally from it, and the 

 joint bearing (he claw is bent down at the end, so as to give the 

 foot a very peculiar appearance.
