Of the Iguaniens, genera i — iv. have no palatine teeth ; genera 

 V — xi. have. This gives rise to two sections, indicated by the inte- 

 rior braces. To the last section would belong the fossil animal of 

 Maestricht called Mososaurus.

The five subgenera of the genus Gecko all agree in having the 

 toes wide and dilated ; the Stenodactyli and Gymnodactyli want this 

 character, and are therefore placed as separate genera. To the pre- 

 ceding family, the Iguaniens, belong the Geosurus, Negulosaurus, 

 Iguanodon, and many other fossil animals.
