284 Lacertidx. 



snout poiuted, with the nasal shields feebly swollen, a little long-er 

 than the postoeular part of the head, with sharp canthus and feebly 

 concave loreal region ; a distinct concavity in the middle of the upper 

 surface of the snout, extending to the middle of the frontal shield. 

 Pileus 2^ to 2\ times as long as broad. Neck as broad as the head or 

 a little constricted. Hin<l limb reaching the ear or the eye in males, 

 between the collar and the ear or between the ear and the eye in 

 females; foot 1;\ to 1^;- times as long as the head; toes rather slender, 

 feebly compressed. Tail 2 to 2| times as long as head and body. 



Upper head-shields flat, smooth. Nasals in contact with each other 

 behind the rostral, the suture between them -\ to \ the length of the 

 froutonasiil, which is as long as broad or a little broader than long; 

 prefrontals as long as broad or longer than broad, usually forming a 

 median suture * ; frontal shorter than its distance from the end of the 

 snout, 1^ to 1 ^- times as long as broad, ^ to f of its lateral boi'der in 

 contact with the large supraoculars; parietals 1^ to 1^ times as long- 

 as broad ; interparietal larger than the f i-ontoparieta,ls, in contact with 

 the large but shorter occipital. Two supraoculars, the first as long as 

 or longer than its distance from the anterior loreal, the space in front 

 of it filled by 6 to 15 scales or granides ; 6 or 7 supereiliaries, first 

 longest, separated from the supraoculars by one or two, nearly threef 

 series of granules. Three nasals, lower in contact with the rostral and 

 the fi.rst upper labial, posterior small ; anterior loreal li to 2 times as 

 long as deep, shorter than the second ; 5 or 6, rarely 4, upper labials 

 anterior t-o the sul>ocular, which is keeled below the eye and largely 

 borders the mouth, its lower border much shorter than the upper. 

 Temporal scales granular, smooth ; a naiTow tympanic shield; auri- 

 cular denticulation absent, or reduced to a few projecting granules. 

 Lower eyelid Avith a transparent disc formed of 2, rart^ly 3 or 4, 

 larger black-edged scales, with 2 to 4 smaller ones below. 



4 pairs of chin-shields, the first three in contact in the middle. 

 27 to 35 gular scales in a straight line between the symphysis of the 

 chin-shields and t,he median collar-plate ; no gidar fold. Collar straight, 

 free, composed of 9 to 15 plates. 



Scales juxtapo.sed, granular, smooth, Inrger towards the ventrals, 

 58 to 75 across the middle of tlie body. Ventral plates in 10, rarely 

 12, regular longitudinal and 27 to 34 transverse series; the plates of 

 the median series longer than broad, the others a little broader than 

 long. Preanal region covered with small irregular plates. 



* Separated by small shields in oin' specimen examined )>y Werner, in one 

 from Kuboos, and in (uic i'lcim <ir<ind Neus (McGregor Museum),
