THE SMOOTH SNAKE. 51

 example (captured at the beginning of August) also 

 throve fairly well, but it did not show signs of 

 becoming tame like the other. It was finally sent, 

 on my son's going to school, about the middle of 

 September, to the Zoological Gardens, Eegent's Park. 

 I have noticed above that a very slight tap with a 

 stick appeared to paralyse it, but that in the two 

 cases there noted it soon recovered. Tliis was not

 ('Zool.,' 3114). In this case the snake never stirred, 

 nor recovered in any way, after a blow, apparently 

 no stronijer than those from which the others soon 

 rallied. Mr Kemp -Welch (' Zool.,' 3150) also men-

 knife. In these cases chloroform had to be freely used 

 afterwards before immersion in spirits of wine.

 species is frequent in tlie same localities inhabited by 

 the snake, though, as proved by I)r Blackmore ('Zool.,' 

 9735), it will freely devour our other lizard, Zootoca 

 vivipara, which is also found in some of the situations 

 affected by Coronella lcci:i>i. In confinement it de-

 but would not touch frogs. Those which we kept in
