Enoven 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. Ihave 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.

optimo, circa finem Julii preteriti instituto, obtulit sese 
mihi forte fortuna in monte Schneeberg, Lacerta preegnans, 
quam prehensam, ut servarem, capsule inclusi: preter- 
lapso duorum dierum spatio cum hance iterum aperirem, 
en! apparet illa onere, quod gestaverat, liberata, ac editis 
sex lacertis juvenculis stipata; ovorum in capsula reli- 
quorum vestigia ne minima quidem hac licet sollicite ex- 
cussa, deprehendere licuit ! quod eo magis mirabar, quo &
