upper labials on each side, the female has five ; the masseteric disk is large in the 

 male, small in the female ; the collar-shields are small, as in var. hedriagce. 



The lizard of Cazza Island, near Lissa (3 specimens, received from Prof Kolombatovic), 

 comes very near to this varietj' as regards size and markings, which, however, may be 

 described as black, and the belly is likewise grey in spirit, which perhaps indicates 

 that it was red in life. It further agrees with the specimens from Pelagosa Piccola, 

 in the small size of the collar-plates, the presence of five upper labials on both sides 

 in one specimen and on one side in the other, and in the fine granular scaling 

 (71-76 scales as against CO-70 in specimens from the Dalmatian mainland and 

 Pelagosa, Grande). If the var. adriatica be regarded as worthy of recognition, the 

 specimens from Cazza should be referred to it.

The Wall-Lizards of the Greek Archipelago, which I here group together under the 

 name of var. erhardi, whether brown or green, resemble L. cainjjedris in the shape of 

 the head, the greatest depth of which equals the distance between the anterior border 

 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 the females. Foot a little longer than head. 



The rostral shield is always excluded from the nostril : the series of supraciliary 

 granules is sometimes complete, but as a rule the first, or the first and second supra- 

 ciliaries are in contact with the second supraocular ; the parietals are only a little 

 longer than broad, and in contact witli the upper postocular ; the temporal scales are 

 usually small and granular, with distinct tympanic and masseteric shields; one, two, 

 or three large supratemporals ; occipital usually shorter and broader than the inter- 

 parietal* ; four is the usual number of upper labials anterior to the subocular -j". 



* In a male specimen from S3Ta (L. Mliller) the interparietal and occipital are separated from each otlier, 

 tlie parietals forming a suture between them, as frequenth' happens in var. meKseUensis.
