78 STUDIES OF ANIMAL TYPES 



Directions. (Although the six-lined lizard was used in making 

 the following outline, any one of three or four species will serve 

 quite as well.) 



A. HAUNTS AND HABITS OF LIZARDS. Lizards are com- 

 mon in the woods, around old logs, along rail fences, and 

 about old stumps and brush piles. Some of them are swift 

 of movement, and quickly scurry out of sight. Others 

 climb trees and remain hidden among the leaves and 

 branches. Some can change color to suit the environment, 

 and some of them resemble the bark of trees upon which 

 they live. 



B. STUDY OF A LIVING LIZARD. Put a lizard in a box 

 containing some moist earth, leaves, and a piece of wood 

 beneath which it may hide. Cover with wire netting. 

 If it is desired, the wire netting may be removed when the 

 animal is under observation. 



Study its mode of locomotion and rate of movement. 

 See if it can climb a sharply inclined, smooth surface. 

 Try it on a rough surface like the trunk of a tree or piece of 

 branch with rough bark. Test its sight. Is its vision 

 keen? Offer it some living flies, beetles, bugs, etc. How 

 does it catch and eat them? Does it eat many? What 

 can be said of its economic value in destroying injurious 

 insects ? 



Offer it water and try and determine whether it drinks or 

 not. If it does drink, determine the manner in which this 

 is done. 



Determine the number of eyelids. Thrust a pencil 

 toward the eye and observe the movements of the nicti- 

 tating membrane which can be drawn over the whole eye. 

 This membrane comes out from the inner corner of the eye, 

 where it lies folded when not in use.
