1. Lenoth (in niilliinetfes) from snout to vent. 2. Number of scales across middle of body. 

 3. Transverse series of ventral plates. 4. Number of plates in collar. 5. Number of scales and 

 granules between symphysis of chin-shields and median collar-plate. 6. Number of femoral 

 pores (on right and left sides, if differing). 7. Number of subdigital lamellae under the 

 fourth toe. 



This explanation applies to the tables for the species following, unless otherwise stated. 



Habitat. Crimea and the North Coast of the Black Sea, Roumania, Bulgaria, Turkey 

 in Europe, Serbia, Hungary, Greece, and Ionian Islands. 



I regard Lacerta taurica as one of the most primitive species of the L. muralis 

 group, owing to its palatal dentition, short head, serrated collar, often hexagonal and 

 keeled dorsal scales, more or less pointed caudal scales, etc. The var. ionica connects 

 it with Lacerta muraMs, vars. campcbtris and Jiumana. If I am right in regarding a 

 dark vertebral stripe or series of spots as a primitive character, the typical L. taurica, 

 in which it is always absent or merely represented by a few spots on the nape *, may 

 be derived from the var. ionica, in which it is sometimes present. As I have observed 

 above, the brown colour is more primitive than the green, and the young L. agilis and 

 L. taurica show no green ; but, whereas in the evolution of Z. agilis the green colour 

 appears first on the sides, before invading the back, the reverse obtains in L. taurica 

 and L. muralis.
