10 Lacertid:e. 



females, the axil, the shoulder, or the collar in males ; foot \\ to 

 1^ times as long as head ; toes slender, compressed. Tail 2 to 2| 

 times as long as head and body. 



Nostril separated from the upper labial and the postnasal hy a 

 narrow rim ; nasals forming a suture behind the rostral, the suture 

 J to f the length of the frontonasal, which is broader than long and 

 broader than the internarial space ; prefrontals forming a short 

 median suture ; frontal as long as its distance from the end of the 

 snout or a little shorter, 1| to 2 times as long as broad, angular or 

 rounded in front, narrower behind, not or but feebly grooved ; parietals 

 1| to 1| times as long as broad; interparietal 2 to ^ times as long 

 as broad, in contact with the occipital, which is usually broader and 

 about half as long. 4 supraoculars, first small and sometimes broken 

 up into 2 or 3, as often as not in contact with the frontal, second and 

 third large and equal or second a little longer, fourth small and usually 

 broken up into 2 or 3 ; 6 or 7 superciliaries, separated from the 

 supraoculars by a complete series of granules, or first in contact 

 with the first and second supraoculars. Lower eyelid somewhat 

 transparent, with feelily enlarged scales in the middle, some of which 

 may be deeper than the others. Rostral not entering the nostril ; 

 a single postnasal ; anterior loreal shorter than the second ; 5, rarely 4* 

 upper labials anterior to the subocular, which is narrower beneath 

 than above. A long, narrow upper temporal, usually in contact 

 with the fourth supraocular, usually followed ]>y one or two small 

 shields ; temporal scales very small and granular above, much larger 

 beneath ; a curved tympanic shield. 



4 pairs of chin-shields, sometimes followed by a small fifth, first 

 three in contact in the middle; 21 to 28 gular scales in a straight 

 line in the middle, granular in front, gradually or abruptly enlarged 

 and imbricate towards the collar ; no gular f(5ld. Collar with 

 strongly serrated edge, composed of 7 to 10 (exceptionally 4) plates. 



Scales granular and smooth on the nape, rhombic and keeled on 

 the body ; 2 or 4 series of hexagonal plates along the back, more 

 or less strongly keeled, rarely faintly keeled ; 33 to 40 plates and 

 scales across the middle of the body ; 12 to 18 large keeled scales in a 

 transverse series between the hind limbs. Ventral plates in 6 longi- 

 tudinal and 27 to 32 transverse series (27 to 30 in males, 30 to 32 in 

 females), the border of the transverse series feebly notched between 

 the plates, the median pair of which is narrower than the others. 

 Preanal plates small and irregular, or two or three enlarged ones in 

 the middle, in a longitudinal series, or three forming a triangle. 



* 4 in two specimens only.
