"Chameleon is a genus of reptiles belonging to the Saurian or lizard-like order, a native of parts of Asia and Africa. The very remarkable power which these animals possess of changing their color, at a very early period called the attention of observers to their habits. Its skin is composed of a sort of small, scaly grains, and under ordinary circumstances is of a greenish gray color. The eyes are capable of moving independently of each other, taking different directions at the same moment."&mdash;(Charles Leonard-Stuart, 1911)

Draco volans, or the Flying Dragon, is a member of the genus of gliding lizards Draco. It can spread out folds of skin attached to its movable ribs to form "wings" that it uses to glide from tree to tree over distances upwards of 8 meters (25 feet); however, like all modern reptiles, it lacks the ability to sustain powered flight, and is capable only of gliding. Its wings are brightly colored with orange, red and blue spots and stripes, and they provide camouflage when folded. The flying dragon can reach lengths as long as 19 - 23 cm. It feeds on arboreal ants and termites.

Found in Oueensland and other parts of Australia, this lizard belongs to the family Agamidae. It reaches a length of about thirty-two inches, and receives its name from the presence of a large expansion of skin at either side of the neck. This frill is notched at the edge, has special supporting cartilages, and by means of muscles can be folded or expanded at will. The lizard walks upon its hind limbs, like the extinct Iguanodon, having the fore limbs hanging down. When at bay, it expands the frill to its fullest extent and opens the mouth wide, exposing its teeth. It inhabits sandy districts.

"Lizard is the popular name of numerous reptiles having usually two pairs of limbs and an elongated body terminating in a tail. The lizards number more than a thousand species, accommodating themselves to all conditions except cold, and increasing in size and number in tropical regions. Some lizards are vegetable feeders, but for the most part they are carnivorous and live upon small birds, insects, etc. The eggs are deposited and left to be hatched without care from the parents. The chief families of lizards are the skinks; the geckos; the iguana; and the chameleons. Poison glands are wanting in the lizards; the only exception being the Heloderma of Arizona and Mexico, which is capable of inflicting a poisonous bite by means of poison glands connected with grooved teeth."&mdash;(Charles Leonard-Stuart, 1911)
