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.
