In conclusion, considering that even the most distinct and striking forms of this 
polymorphic lizard are linked with the typical Lacerta muralis in such a way as to 
preclude a precise definition, such as we have a right to claim in dealing with specific 
entities, I feel bound to adhere to the conception of Lacerta muralis in the wide 
sense in which I have hitherto taken it. JI even feel unable to draw up short 
definitions or a key by which the identification of the numerous forms with which we 
are now acquainted could be ensured in a satisfactory manner. 
A geographical arrangement therefore appears to me the best to follow for the 
present * :—
