Habitat. — This species inhabits Morea; its reported occurrence in 

 Crete requires confirmation. 



Lacerta peloponnesiaca is most nearly related to L. taurica, from 

 which it differs chiefly in the larger head in the male, the non-serrated 

 collar, the truncate or very indistinctly pointed caudal scales, and the 

 nearly constant absence of granules between the supraoculars and the 

 superciliaries. The latter character and the strong palatal dentition 

 separate it from L. muralis. 



In some respects (stronger palatal dentition, absence of grannies 

 between the supraoculars and the superciliaries, more pronounced 

 striation) this species is phylogenetically less advanced than L. tawricar 

 but in all others it has evolved further from the hypothetical ancestral 

 form. For reasons explained above (p. 34) I regard the coloration 

 of the young as the most primitive in the L. muralis group, as in 

 some specimens the original five light dorsal streaks are preserved 

 on the nape ; but on the sides the light streaks are reduced to one,, 

 the median lateral of L. agilis.
