also that of the carpi, palms, and soles, are covered with very small 

 scales. The fingers and toes are slender, unequal, covered above with 

 small scales, and protected beneath with transverse, slightly curved, 

 undivided plates. The last joint, in all, is slender and compressed, 

 scaly, and terminated by a small, acute, and curved nail. 



The tail, in the specimen before us, is reproduced, so that its abso- 

 lute length cannot be determined with certainty ; it is thickish, and 

 depressed at the base, conical, and tapering off posteriorly ; its base, 

 above and sideways, is granular, whilst inferiorly may be observed 

 small rhomboid scales, as well as three conical, spine-like processes, 

 forming a group on either side, the points directed backwards ; the 

 rest of the organ appears to be covered with verticils of small, elongated, 

 and narrow scales. 



The upper regions exhibit a dark reddish-orange ground, over which 

 are distributed, black, elongated patches, contiguous upon their ex- 

 tremities, so as to simulate longitudinal bands or series; these spots 

 are likewise contiguous upon their sides, so as to give somewhat the 

 appearance of transverse interrupted bands. The head and limbs are 

 marmorated with black. Beneath, the color is of a uniform greyish- 

 red or brown. The small spines on the sides of the tail are : the two 

 uppermost, white; the lowermost, black.
