Enough has been said in the account of the former 

 species on the subject of the nomenclature and synonymy 

 both of that and of the present subject. I have there 

 attempted to shew that the Linnean name agilis has been 

 hitherto improperly applied to this common species, and 

 that it belongs to our other indigenous Lizard. It remains 

 now only to say a few words on the identity of the present 

 one with the Lacerta vivipara of the younger Jacquin. 

 An examination of the figure in that author's paper will 

 shew that this synonymy is correct ; and it is entirely 

 confirmed by the fact of the ovo- viviparous character of 

 our species. The following graphic and interesting account 

 I copy from the paper referred to ; and as the work is 

 comparatively little known in this country, I make no 

 apology for thus giving it in detail. It is an additionally 

 interesting circumstance that this worthy son of so distin- 

 guished a father was only eleven years old when these 

 observations were made.
