122 Lacertidse. 



in females. Foot 1 to 1^ times length of head ; digits rather thick 

 and feebly compressed distally. Tail cylindrical, or squarish and a 

 little depressed at the base, about twice as long as head and body. 



Nostril pierced between three shields. Suture between the nasals 

 not half the length of the frontonasal, which is broader than long and 

 broader than the internarial space ; prefrontals forming an extensive 

 suture ; frontal as long as its distance from the nasals, 1|- to 1^- 

 times as long as broad in adults (about twice in young), broader 

 than the supraoculars ; parietals 1^ to If times as long as broad, not 

 in contact with the upper postocular ; occipital as long as or shorter 

 than the interparietals, and usually broader, sometimes as broad as 

 the frontal ; a small shield sometimes intercalated between the inter- 

 parietal and the occipital. Four supraoculars, first and fourth small, 

 second sometimes a little longer than third ; 5 to 7 superciliaries, 

 suture between the first and second oblique ; a complete or incomplete 

 series of granules, 7 to 12 in number, between the supraoculars and 

 the superciliaries. Rostral not touching the nostril ; a single post- 

 nasal,* a little smaller than the anterior loreal, which is about half 

 as long as the second and sometimes divided into two ; 6 or 6 upper 

 labials t anterior to the subooular, which is more or less narrowed 

 beneath ; 2 or 3 large upper temporals, the first in contact with the 

 fourth supraocular ; below them the temple is covered with granular 

 scales, larger in front and beneath, enclosing a large masseteric shield ; 

 a narrow tympanic shield, sometimes broken up.J 



Pterygoid teeth present. 



Gular scales granular in front, a series often separating the third 

 pair of chin-shields, larger and feebly imbricate towards the collar ; 

 37 to 49 scales in a straight line between the symphysis of the chin- 

 shields and the median collar-plate; no gular fold. Collar not or 

 but feebly serrated, composed of 10 to 17 plates, the median some- 

 times larger, sometimes smaller, than the others. 



Dorsal scales oval or rhomboidal, rather strongly keeled, surrounded 

 by circles of minute granules ; 79 to 93 scales across the middle of 

 the body ; 36 ( (^ ) to 50 ( J ) transverse series of scales, in the middle 

 of the back, correspond to the length of the head, 3 or 3 and 4 on 

 the sides to the length of one ventral plate. Ventral plates in 

 16 to 20 longitudinal series, squarish or a few broader than long; 

 on the posterior half of the belly the plates do not form regular 

 longitudinal series, but are oblique or tessellated ; 33 to 36 transverse 



* Occasionally divided into 2 or 3 according to Schenkel. 



t 6 in 7 cases out of 20. 



:j: Altogether 75 to 110 scales and shields on the temple, as against 30 to 36 

 in L. simonyi.
