274 SAURIA. 



face of the head resemble those of the back, being but slightly larger 

 upon the snout. The upper labials are lined with a series of very small 

 plates. The upper surface of the limbs is granular also, except upon 

 the carpus and tarsus, where the granules give way to small scales. 

 The abdominal region is covered by genuine scales, larger upon the 

 middle of the abdomen, where they are subquadrangular, than on the 

 chest and pelvis, where they are subpyramidal in their outline ; they 

 are largest upon the middle femoral region, where, in the male, twenty 

 pores on either side constitute a curved series, with the extremities of 

 the scales contiguous upon the medial line. The scales upon the pre- 

 anal region are equal to those on the pelvic region, but on the posterior 

 portion of the thighs they assume a granular aspect. Under the leg. 

 properly so called, the scales are as large as on the middle femoral 

 region. The skin is exceedingly tender, and easily lacerated in the 

 attempt to capture these animals. 



The tail is subconical, slightly depressed, provided, upon the infe- 

 rior mesial line, with a double series of rather large and somewhat 

 irregular scales or plates ; and, on each side of these, may be observed 

 small and polygonal scales, passing to granules as they approximate 

 the upper surface of that organ. 



The upper regions are reddish-brown, spotted with white, and, occa- 

 sionally, exhibiting a few black markings. The inferior regions are 

 unicolor, of a whitish hue. 



Loc. Specimens of this species were collected on the Navigator 

 Islands, and at Taheiti also. They were "often seen about the trunk 

 of the trees, in the daytime, about the cocoanut tree, and also in the 

 interior forest."
