 kind of menace, in order to deter its enemy ; but 

 it is incapable of doing any mischief by its bite or 

 otherwise.

Green Carolina Lizard. Catesh. 2. pi. 65. 



This, which appears to resemble the former in 

 every particular, except in the extensile gular 

 skin, is said by Catesby to be very common in 

 Carolina, frequenting houses, and becoming in 

 a degree familiar, so as to sport about the ta- 

 bles and Avindows, catching flies with great dex- 

 terity, appearing chiefly in summer, and on the 

 approach of cold weather retreating to its winter 

 quarters, lying torpid in the hollows of trees, &c. 

 It is sometimes tempted to leave its retreat pre- 

 maturely, and, on a change of weather, becomes 

 so enfeebled by the cold as to perish before it 

 regain its habitation. Its colour is observed to 

 change very considerably, appearing of a bright 

 green in dry hot weather, and changing to brown 

 in cold weather : the structure of the feet in these 

 lizards is similar to that of the L. Principalis^ 

 the toes being slender and somewhat dilated to- 

 wards the tips. The red expansile gular pouch is 

 perhaps pecidiar to the male.
