 general reader. It may be observed, however, 

 that in this species there are to be found, in

 the upper and lower jaws, also a few very small 

 ones seated on the back part of the palate, and 

 which are wanting in the common lizard. 



Professor Bell states on the faith of a gentle- 

 man of his acquaintance, that the brown varieties 

 are confined to sandy heaths, the colours of which 

 are closely imitated by the surface of the body, 

 and that the green variety frequents the more 

 verdant localities. This, he adds, he had not 

 been in a position either to refute or confirm, 

 and could only vouch for the existence of two 

 such varieties, at a comparatively short distance 

 from each other.
