^04 Lacertidse. 



distinguished by a greyish greeu or bluish grey grouud-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 heail ; belly greyish (in spirit). 



The tail is rather thick in its basal part, does not taper so gradually 

 <is in other lizards of this group, as pointed out by Schreiber. 



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

 scales are round granules without distinct keel ; the first suj^raocular 

 is normal in the male examined by me, but is broken up into two or 

 thi'ee granules in the female ; the male has four anterior upper labials 

 on each side, the female has five ; the masseteric shield is large in the 

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

 bedriagfe. 



The lizard of Cazza Island, near Lissa (var. casZc-F, Schreiber), comes 

 very near to this variety as regards size and markings, which, how- 

 ever, may be described as black, and the belly is likewise grey. It 

 further agrees with the specimens from Pelagosa Piccola in the small 

 size of the collar-plates, the presence of five upj^er labials on ])oth sides 

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

 scaling (71-76 scales as against 60-70 in specimens from the Dal- 

 matian mainland and Pelagosa Grande). If the var. adriatica be 

 r(>garded as worthy of recognition, the specimens from Cazza should be 

 referred to it. 



Specimens from Scoglio Susae, near Lissa, which I received alive 

 from M. de Southoff, were very similar to the above, but the scales 

 across the body number only 63 to 71. Greyish or I'eddish brown 

 above, vertebral region sometimes (males) of a pale, dull green ; a 

 vertebral series of large l)lack spots which may be confluent into a 

 band with scalloped edges ; females with 6 light lines or series of 

 light spots ; tail with black and white spots foriniug l>ars on the sides. 

 Lower parts purplish grey to dull lilac, with turquoise-blue spots on 

 the sides. Other specimens are very dark, almost black, above, and 

 dark grey below, and very similar to those found on S. Stefano, near 

 Naples. 



According to Schreiber, specimens indistinguishal)le from the Cazza 

 lizard occur also on St. Andrea Island near Lissa, alongside with a black 

 form referred by him to the var. melisellensis oi Braun, with which it is 

 connected by numerous intermediate specimens, and also another black 

 form described from a single example under the name of var. argue. 

 More slender in habitus, with a longer and thinner tail (more than 

 twice as long as head and body). Dark olive-brown above, black on
