 water, or under the shrubs on its banks. Eats 

 grains and worms : we have found in its stomach

 four feet. Its flesh is eaten. 



The Iguanas, proper. Iguana, Cuv. 



Have the body and tail covered with small imbri- 

 cated scales. All along the back is a range of spines, 

 or rather of raised scales, compressed and pointed ; 

 and under the neck, a compressed and pendant cuti- 

 cular appendage, the edge of which is sustained by 

 a cartilaginous production of the hyoid bone. Their 

 thighs have the same range of porous tubercles as 

 those of the lizards proper, and their head is covered 

 with plates. Each jaw is surrounded with a range of 

 compressed triangular teeth, with indented edges. 

 There are also two smaller ranges on the posterior 

 edge of the palate.
