"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."—(Charles Leonard-Stuart, 1911)
