 prefer to deep valleys and woods. 



Habits. — Keptiles are frequently described as being 

 sluggish and slow of movement. This is certainly not

 are about to grasp it, like a flash it darts out and

 attempting to see the individual movements of the 

 limbs it is a sheer impossibility. In fact, all the

 take readily to water. It is also stated that when
