WALL LIZARD 
from its hiberniatng quarters during mild weather in 
Winter. The members of the Family Lacertide, or 
True Lizards, are most common in Africa, but they 
have a wide distribution in various parts of the Old 
World, and frequent Northern lands where one would 
hardly expect to find creatures of this nature eking out an 
existence. Being so difficult to study at close quarters 
in their own haunts, much remains to be discovered 
concerning these useful, harmless, and active little 
reptiles. Fortunately they take more or less kindly to 
captivity, and soon regard their owners with familiarity. 
They may thus be highly recommended as suitable pets 
for a Vivarium, and if careful observation is kept and 
notes made, the young reptile student is quite likely to 
be able to assist in helping to unravel some of the un- 
solved mysteries still surrounding them.
