'290 Lacertidm. 



rather obtusely pointed, witli the nasals more or less swollen, as long 

 as the postocular part of the head ; a distinct concavity in the middle 

 of the upper surface of the snout, extending to the middle or the 

 posterior extremity of the frontal shield. Pileus IJ to 2 times as long 

 as broad. Neck as broad as the head or a little narrower. Hind limb 

 reaching the ear or between the collar and the ear in males, the 

 shoulder, the collar, or between the collar and the ear in females ; foot 

 li to 1^ times a-s long as the head ; toes rather slender, feebly com- 

 pressed. Tail If to 2J times as long as head and body. 



Upper head-shields flat or feebly convex, smooth or feebly rugose 

 and pitted. Nasals in contact with each other behind the rostral, the 

 suture between them ^ to ^ the length of the frontonasal, which is 

 broader than long ; prefrontals longer than broad, forming a short 

 median suture or* separated by an azygos shield ; frontal as long as 

 or shorter than its distance from the end of the snor.t, \\ to If times 

 as long as broad, not more than ~ of its lateral border in contact with 

 the large supraoculars, sometimes t separated from them by a series of 

 small scales : parietals as long as broad or a little longer than broad ; 

 interparietal as large as or larger than the frontoparietals ; occipital 

 small, i to ^ the length of the interparietal, sometimes minute and 

 separated from the latter by the parietals meeting in the middle. Two 

 supraoculars, together not longer than ^ the supraocular region, the 

 first usually shorter than the second, and as long as or shorter than 

 its distance from the anterior loreal, the space in front of it filled bv 

 2 to 6 transverse series of small shields or granules : 5 to 9 super- 

 ciliaries, separated from the supraoculars by "2 to 4 series of granules. 

 Three nasals, lower in contact with the rostral and the first upper 

 labial, posterior small and sometimes excluded from the nostril ; 

 anterior loreal as long as deep, shorter than the second ; 4 or 5, i-arely 

 6, upper labials anterior to the subocular, which is keeled below the 

 eye and largely borders the mouth, its lower border much shorter 

 than the upper. Temporal scales granular, smooth or obtusely keeled ; 

 no tympanic shield : 3 or 4 obtuse or pointed lobules project in front 

 of the ear. Lower eyelid with a transparent disc formed of two large 

 black-edged scales, sometimes with 2 or o smaller ones below. 



4 pairs of chin-shields, the first two (rarely three) in contact in the 

 middle. 33 to 43 gular scales in a straight line between the symphysis 

 of the chin- shields and the median collar-plate ; no gular fold. CoUar 

 straight, free, composed of 10 to 15 plates. 



Scales juxtaposed, granular, smooth or obtusely keeled on the neck,
