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 

 show that the Linn can name agilis has been hitherto impro- 

 perly 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 show that this syno- 

 nymy 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 re- 

 ferred 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 distinguished a father was only eleven years old 

 when these observations were made.
