150 Lacertidx. 



parietals meetiui;' in the middle. 4 supraoculars, first very small, 

 second longer than third, fourth small but larger than first ; 3 super- 

 ciliaries, first and second elongate ; a complete series of granules 

 between the supraoculars and the superciliaries. 



Nasal usually forming a suture with its fellow behind the rostral* 

 and in contact with the anterior loreal above the postnasal, unless its 

 posterior portion be detached to form a second postnasalt ; anterior 

 loreal as long as or shorter than second ; 4 upper lal)ials;I: anterior to 

 the subocular, which is not or but little narrower beneath than above. 

 Tempoi'al scales very small, granular, obtusely keeled, 12 on a line 

 between the orbit and the tympanum ; a feebly enlarged anterior 

 upper temporal ; a very narrow tympanic shield. 



4 pairs of chin-shields, § the 3 anterior in contact in the middle. 22 

 to 24 gular scales in the median line, anterior granular and faintly 

 keeled, posterior increasing in size, imbricate, keeled, and merging 

 gradually into the plates of the very distinct collar, which are pointed, 

 keeled, and 10 to 12 in numlier. 



Dorsal plates obtusely pointed or rounded behind, in 7 or 8 longi- 

 tudinal series on the body, the median smaller. || Ventral plates 

 obtusely pointed and mucronate, very strongly keeled, in 6 longitudinal 

 and 27 or 28 transverse series. 2 or 3 series of keeled scales on the 

 side above the ventral plates, separated from the dorsals by a broad 

 granular area. 28 to 32 plates and scales round the middle of the 

 body. Preaual plate rather large,T[ bicarinate, with one or two smaller 

 keeled plates on each side. 



Upper surface of limbs with rhombic keeled scales. A single 

 femoral pore on each side. Subdigital lamellae single or partly single 

 and partly paired, 24 under the fourth toe. 



Caudal scales strongly keeled and shortly mucronate, in subei|ual 

 whorls, the fourth containing 12 or 14 scales. 



Bright green above ; a white streak along each side, from the upper 

 lijo to the groin, passing below the tympanum and along the U[)per

X 5 in the type specimen described by Van Denburgh. 



§ 5 in one specimen, 3-4 in another, according to Van Denburgh, whose 

 description is based on 52 specimens. 



|! According to Van Denburgh, there are usually two median series of small 

 plates anteriorly and one posteriorly, or 3-2 1, 2-1-0, one throughout, or 1-0- 

 One specimen has only 1 row of large plates on each side, separated by about 

 7 rows of smaller, irregular plates. 



T[ Exceptionally divided, according to Van Denburgh.
