sentative groups. There are, however, certain iguanoids, such as the anolis 
lizards and the sea-lizards which have no representatives in the preceding family. 
The majority of the iguanoids feed on insects, although some, like the true 
iguanas and the sea-lizards, subsist on a vegetable diet, while one genus is stated 
to be omnivorous. Only two genera are known to produce living young. 
In the forests, groves, and gardens of all the warmer regions of 
America live a number of beautiful lizards commonly known by the 
name of anolis, which is applied in the Antilles to some members of the group. 
The distinctive features of these lizards are the pyramidal form of the head, the 
moderately long neck, the presence of a broad and generally brilliantly-coloured 
appendage on the throat of the males, the slender body, w T hich may be either com-

pressed, cylindrical, or slightly depressed, the relatively long hind-limbs, the large 
feet, in which the toes are of very unequal length, and their middle joints expanded, 
with smooth transverse plates on the under surface, and the long, curved, and sharp 
claws, which are raised above the level of the expanded joints. The tail is long and 
hard, although not prehensile; the covering of very minute scales on the back and 
tail is not unfrequently elevated to form a crest; the cheek-teeth are characterised 
by their distinctly tricuspid crowns; and teeth are generally present on the pterygoid 
bones of the palate. Lastly, these lizards possess the power of changing their 
colour to even a greater extent than is the case with the chanueleons. From 
among more than one hundred species belonging to the genus we select for 
illustration the red-throated anolis (Anolis carolinensis), which inhabits the 
South-Eastern United States and Cuba, and presents the following distinctive 
features. The head, which is long, triangular, and depressed, is nearly smooth in
