VARIETIES OF THE WALL-LIZAED. 181 



female specimens. Males usually have a black vertebral stripe, straight or wavy, or 

 a vertebral series of large black spots, separated from the spots on the sides by a 

 narrower streak of the ground colour; these spots may form longitudinal series, coarse 

 marblings, or cross-bars.

A female 48 mm. long from snout to vent is gravid. 



As regards the scaling, I note the following departures from what is normal in the 

 var. serpa. The series of granules between the supraoculars and the supraciliaries 

 is usually complete; in 5 specimens out of 18 the parietal is not in contact with 

 the upper postocular ; one specimen has 5 anterior upper labials, and two lack the 

 masseteric disk. 



The var. adriatica is described by Werner as distinguished by a greyish-green or 

 bluish-grey ground colour with the markings much less sharply defined, of a dark 

 greyish brown. These markings consist of a dark vertebral stripe with round light 

 spots, and a dark network on the sides enclosing round light spots ; small dark spots 

 on the head ; belly greyish (in spirit).

One of these specimens is figured on PL XX. fig. 9. 



4 or 5 rows of scales correspond to one ventral plate ; the dorsal scales are round 

 granules without distinct keel; the first supraocular is normal in the male, but is 

 broken up into two or three granules in the female ; the male has four anterior
