The extensive family Agamidse — the Eastern representative 

 of the Iguanas — is highly characteristic of the Oriental region, 

 which possesses about half the known genera and species. Of the 

 remainder, the greater part inhabit the Australian region ; others 

 range over the deserts of Central and Western Asia and Northern 

 Africa, as far as Greece and South Eussia. One genus extends 

 through Africa to the Cape of Good Hope, and there are three 

 peculiar genera in Madagascar, but the family is very poorly 

 represented in the Ethiopian region. Many of these creatures 

 are adorned with beautifully varied and vivid colours, and the 

 little " dragons " or flying-lizards are among the most interesting 

 forms in the entire order. The larger genera are distributed as
