The remaining , genera mostly consist of single species, and 
are pretty equally distributed over the various parts of the world 
indicated in the preceding list. Madagascar, the Seychelle Islands, 
Chili, the Sandwich Islands, South Africa, Tahiti, the Philippine 
Islands, New Caledonia, and Australia — all have peculiar genera, 
while two new ones have recently been desciibcd from Persia.

The extensive family of the Iguanas is highly characteristic 
of the Neotropical region, in every part of which the species 
abound, even as far as nearly 50° South Latitude in Patagonia. 
They also extend northwards into the warmer parts of the 
Nearctic region, as far as California, British Columbia, and 
Kansas on the west, and to 43° North Latitude in the Eastern 
States. A distinct genus occurs in the Fiji Islands, and one 
has been described as from Australia, and another from 
Madagascar, but there is some doubt about these. The most 
extensive genera are : — 
Anolius (84 sp.), found in most parts of Tropical America and
