in the same detail as in the case of the other 

 species. 



Distribution. — The wall lizard is a very common 

 sj)ecies in the countries of South Europe, as well as 

 across the Mediterranean in Xorthern Africa. It is 

 also common in Asia Minor. To the north its dis- 

 tribution extends as far as the more southern portion 

 of Germany, and into Belgium. Dr. Gadow states 

 that in the Iberian Peninsula it is found at an altitude 

 of 5000 or 6000 feet above the level of the sea. 

 Speaking generally, the distribution of tliis species 

 may be said to be chiefly in those countries bordering 

 upon the Mediterranean.

 supra-ocular and' supra-ciliary scales, and usually by 

 having only six rows of ventral scales. The great
