The wall-lizards of the Grecian Archipelago, which I group 

 together under the name of var. erhardi, whether brown or green, 

 resemble the var. campestrig in the shape of the head, the greatest 

 depth of which equals the distance between the anterior corner or the 

 centre of the eye and the tympanum ; the snout is short and obtusely 

 pointed. The hind limb reaches the axil or the shoulder in males, the 

 elbow of the adpressed fore limb in females. Foot a little longer 

 than head. 



The rostral shield is always excluded from the nostril ; the series of 

 superciliary granules is sometimes complete, but as a rule the first, or 

 the first and second superciliaries are in contact with the second supra- 

 ocular ; the parietals are only a little longer than broad, and in 

 contact with the upper postocular ; the temporal scales are usually 

 small and granular, with distinct tympanic and masseteric shields ; 

 one, two, or ■ three large upper temporals ; occipital usually shorter 

 and broader than the interparietal * ; four is the usual number of 

 upper labials anterior to the subocular.f 



Collar not serrated, with 9 to 11 (rarely 8) plates, which may be 

 very small ; gular fold very distinct ; 27 to 35 scales and granules 

 between the symphysis of the chin-shields and the median collar- 

 plate. 



Dorsal scales small, granular, round or oval, smooth, rarely faintly 

 keeled, equal in size, 54 to 63 across the middle of the body, 3 and 4 

 series corresponding to one ventral plate, 38 to 56 to the length of 

 the head. Ventral plates in 26 to 34 transverse series (26-30 in 

 males, 31-34 in females). Preanal plate moderate, with one or two 

 semicircles of small plates. 



Scales on upper surface of tibia feebly keeled, considerably smaller 



* In a male specimen from Syra (L. Miiller) the interparietal and occipital 

 are separated from each other, the parietals forming a suture between tliem, 

 as frequently happens in var. melisellensis ; in a female from Delos a small 

 shield separates them.
