CLASS III.— REPTILIA. 



XXVU 



ORDER II.— Sauria. 



From the considerable differences existing between animals pos- 

 sessing the general characters of this order, it has been found ne- 

 cessary to divide it into six families, represented severally by the 

 Crocodiles, Monitors, Iguanas, Geckos, Cameleons, and Skinks ; of 

 these families, the first and fifth have each only one genus, the 

 second two, and the others have several genera.
