416 SAURIA. 



a good deal larger than those on the sides of the body, anteriorly elon- 

 gated, sublanceolated, whilst posteriorly, they approximate more to a 

 rhombic shape; they are strongly carinated, with their posterior anajle 

 very acute, being the prolongation of the keel, on the sides of which 

 a small notch is sometimes observed. 



The limbs are moderate : the anterior pair being smaller than the 

 posterior, for, when stretched backwards alongside the body, they do 

 not attain the groins, whilst the posterior pair, similarly brought for- 

 wards, will reach the orbit ; their upper surface is covered with some- 

 what large, subrhombic, or lanceolated, and carinated scales, disposed 

 upon longitudinal series ; on the inferior surface of the arm, forearm, 

 and thighs, they are small, subrhombic, carinated ; under the legs, 

 properly so called, again larger, sublanceolated, and strongly carinated. 

 A series of distant femoral pores may be observed in the male, the 

 series from either side being continuous across the interfemoral region. 

 Under the palm of the hands and sole of the feet, the scales are very 

 small, subrhombic, tricarinated, like the transverse plates under the 

 fingers and toes. The upper surface of the digits just alluded to is pro- 

 tected by well-developed, imbricated, and carinated scales. The nails 

 are compressed, curved^ stoutish at their base, and acute upon their 

 extremity. The tail is subconical, twice and a half as long as the 

 body and head combined, covered with imbricated scales ; those of its 

 upper surface of the size and shape of the large dorsal ones, to, at 

 least, one-third of the length of the organ, and those of its inferior sur- 

 face, like the abdominal ones, upon the same extent. Upon the re- 

 maining length, the scales are subrhombic, similar all around, imbri- 

 cated, resembling those of the upper surface of the toes ; they are 

 strongly carinated, especially upon the anterior portion. 



The coloration varies somewhat according to age. The specimens 

 which we have described are about of the average size the species 

 attains. The upper surface of the head is dark brown. A series 

 of angular black spots may be seen along the dorsal region, with the 

 intermediate spaces of a light brown hue. On each side of these 

 dark spots, there is a light fulvous band, sometimes crossed by the 

 spots. The sides of the body being variegated with light brown, and 

 dark spots or irregular streaks. The limbs and tail are barred with 

 fulvous or light brown and black. The inferior surface of the animal 

 is unicolor, of a light brown hue. A young male specimen exhibits a 

 fulvous band across the interocular region, lined, in front and behind,
