VARIETIES OF THE WALL-LIZAED. 197 



Rostral not entering the nostril ; suture between the nasals very short * ; nasal 

 sometimes forming a suture with the anterior loreal ; frontal as long as or shorter than 

 its distance from the end of the snout ; series of granules between the supraoculars 

 and the supraciliaries usually complete ; occipital much shorter, and often broader 

 than the interparietal ; parietal more or less distinctly emarginate on the side f for 

 the accommodation of a large supratemporal, which is usually in contact with the upper 

 postocular ; temporal scales granular ; masseteric and tympanic shields usually large J ; 

 usually four, sometimes three or five, upper labials anterior to the subocular. 25 to 

 34 scales and granules in a straight line between the symphysis of the chin-shields 

 and the median collar-plate ; gular fold absent or feebly marked ; collar-edge entire ; 

 7 to 11 collar-plates. 



Scales on body oval or oval-hexagonal, more or less distinctly keeled, somewhat 

 enlarged towards the ventrals, 45 to 52 § across the middle of the body, 35 to 40 

 corresponding to the length of the head, 3 or 4 or 2 or 3 to one ventral plate. 



Ventral plates in 6 longitudinal and 24 to 29 transverse series. Prseanal plate large, 

 usually preceded by a transversely enlarged plate. 



Scales on upper surface of tibia considerably larger than dorsals and strongly keeled. 

 15 to 23 (usually 16 to 21} femoral pores on each side. 25 or 26 lamellar scales 

 under the fourth toe. 



Upper caudal scales very strongly keeled, those on the sides raised, subtrigonal, 

 almost spinose, truncate behind ; the whorls alternately longer and shorter, and the 

 scales of the two median dorsal series of every other whorl much voider than the 

 others. 18 to 26 scales in the fourth whorl behind the postanal granules. 



Brown or greyish olive above, darker on the sides, which have round light spots ; a 

 dorso-lateral series of round light spots, or ocelli, which may disappear in the adult ; 

 back with small dark spots, which often form a double vertebral series ; lower parts 

 whitish, with blue spots on the outer row of ventral plates.
