another still across the chest, in advance of the shoulders. The 

 scales of the dorsal and lateral regions are small, assuming somewhat 

 a granular aspect, especially upon the neck, where they are smaller 

 than on the trunk, where they are disposed upon transverse series; 

 they are nearly equal, mayhap, slightly increasing in size on the sides, 

 which they really do as they approximate the abdominal region. On 

 the tail and upper surface of the limbs, the scales are a good deal 

 larger, appear to be imbricated, and conspicuously carinated, except 

 upon the anterior third of the tail, where the carination is scarcely 

 perceptible, and where their arrangement upon annular series is yet 

 quite apparent. Upon the middle region of the abdomen, from the 

 chest to the insertion of the thighs, the scales are but slightly cari- 

 nated, their shape being subquadrangular, elongated, and arranged 

 upon transverse series ; upon the chest and gular region, they are 

 subrhomboid, posteriorly acute, smaller than on the abdomen, and 

 conspicuously carinated ; under the anterior legs, they are a good deal 

 smaller than on the chest, less acute posteriorly, and not quite so 

 strongly carinated; under the hind limbs, they resemble the former, 

 though larger ; and, along the leg proper, they are larger than along 

 the thigh, where, in the male, sixteen femoral pores may be seen, the 

 series from either side not being continuous upon the interfemoral 

 region, where a wide separation exists. Under the palm of the hands, 

 the scales are minute or granular ; under the sole of the feet, small, 

 but distinct ; in both instances, carinated. Under the fingers and toes 

 may be observed transverse, multicarinated plates. The second and 

 third fingers and toes are, moreover, provided, upon their external 

 margin, with a serrated, horny, scale-like expansion. The nails are 

 strong, compressed, curved, and acerated. Under the tail, the scales 

 are the largest of all, elongated, arranged upon transverse series, 

 strongly carinated, the carination constituting several longitudinal 

 ridges. 



The color of some specimens is of a uniform green, of a somewhat 

 darker shade along the back than on the belly, where a yellowish hue 

 predominates. This uniform tint extends to a portion of the tail : the 

 remainder of that organ being annulated alternately brown and 

 blackish. Other specimens present a ground of a dull verdigris, with 

 transverse bands or fasciae of a bright green hue. One of these bands 

 is situated across the shoulders, wide above, and diminishing towards 

 the insertion of the arms, sending forwards a branch along the neck
