THE GREEN LIZAED, LACERTA VIRIDIS 71 



the absence of species in places apparently well 

 adapted for them. That White was not very familiar 

 with the green lizard is evident from the first sentence 

 of the very next letter (Letter XXIII.), where he says : 

 " It is not improbable that the Guernsey lizard and 

 our green lizard may be specifically the same ; all

 found as escaped captives. I am not aware to what 

 extent they were kept as vivarium pets in the days 

 when Gilbert White wrote, but nowadays a very 

 large number of people have vivaria with them in 

 captivity, and like all lizards they are quick to 

 take the opportunity of a door left open, so that

 locality, but I am not aware of any of these having
