what larger, and slightly keeled under the forearm. The scales on 

 the upper surface of the fore limbs being conspicuously keeled, some- 

 what acuminated, though smaller than on the back. The palms of the 

 hands and soles of the feet are densely covered with small, acute, and 

 keeled -scales, giving these surfaces quite a rough appearance. The 

 fingers and toes are scaly above and sideways, and transversely plated 

 beneath, the fingers being nearly smooth above, whilst the toes are cari- 

 nated: the inferior aspect of both fingers and toes being multicarinated. 

 The nails are compressed, curved, and acute. The scales on the infe- 

 rior surface of the tail are somewhat smaller than on its upper surface, 

 more lanceolated, and less conspicuously keeled. 



The color of the adult is olivaceous-brown above, with narrow, 

 transverse, blackish bands across the back, covering but one scale, 

 margined with a lighter hue. The head is variegated with black; the 

 limbs and tail are unicolor. Beneath, the tint is yellowish ; the chin 

 and throat exhibiting interrupted, longitudinal, black lines. 



The young, as colored from life in May, 1839, exhibits a greyish- 

 brown hue along the dorsal region, with four longitudinal series of 

 small, subtriangular, brownish-black spots, with their bases directed 

 forwards, and contiguous sideways, so as to constitute, as it were, 

 transverse bands or fasciae ; three series of white, intervening spots 

 are also observed behind and contiguous to the dark ones. A lateral 

 series of brownish, much less distinct spots, extends along the upper 

 portion of the flanks, which otherwise exhibit a light greyish hue, 

 variegated with brown and pink. The base of the tail is transversely 

 barred with blackish-brown, whilst it is unicolor posteriorly. The 

 upper surface of the limbs is greyish, transversely barred or macu- 

 lated with darker blotches. The upper surface of the head is reddish- 

 brown ; its lower surface is whitish, with meandriform lines of black. 

 The belly is yellowish-white, obscurely maculated : the spots fading 

 away over the chest ; the belly, limbs, and tail being unicolor. The 

 posterior aspect of the thighs is variegated with black and whitish 

 spots.
