Fig. 6. Green Snake, Liopeltis vernalis. Occurs in wild meadows, but is not fre- 

 quently seen, because of its protective coloration. The scales are of satiny luster 



and leaf green in color. 

 Fig. 7. (Lower) Keeled Green Snake, Opheodrys aestivus. While similar in color- 

 ation to the species figured above, there is a marked difference in the texture of 

 the scales. With this species they are keeled, each showing a raised line or ridge 

 running lengthwise along the center. Both of the green snakes feed upon insects.
