a depression back of the eye. The eyes have movable 

 upper and lower lids. The teeth are attached to the ridge 

 or edge of the jaws, and are not set in sockets. 



Lizards feed on insects, worms, and other small animals, 

 though a few forms are herbivorous. 



Lizards are active in habits, some being called " swifts." 

 They are found on the ground, more often in sandy soils, 

 on rocks, trees, walls, etc., 

 being most abundant in 

 warm countries. There are 

 not many north of latitude 

 40. A few live more or less 

 in the water, but they do 

 not have gills at any stage 

 of their lives. 



Lizards lay eggs of com- 

 paratively large size, which 

 are covered by a tough 

 leathery or limy shell. 



Many lizards are bril- 

 liantly colored, and some 

 have power to change their 

 color ; most noted of these 

 are the chameleon, of the 

 old world, and the Anolis 

 (Fig. 123), found in the 

 Carolinas and Florida, which 

 readily changes from a 

 bright green to a dull brown 

 according to its surround- 

 ings. Put one of these fellows in a box with a lot of dead 

 pine needles, and note the color change. This lizard is 

 often sold under the name "chameleon."
