THE LIZARDS


THE LACERTILIA OR LIZARDS.

LIZARDS.
1. ZEBRA-TAILED LIZARD. 2. PACIFIC SWIFT. 3. COLLARED LIZARD.
4. WHITE-BELLIED SWIFT. 5. COMMON SWIFT OR FENCE LIZARD.

Lizards differ from snakes in that the right and left halves of the lower jaw are joined together by bone instead of elastic ligament and in that they have legs and eyelids. They are found in the warmer climates. Most of them live on insects, but some types as, for instance, the Iguanas, live entirely on vegetable matter, while others prey on birds, mice, frogs, etc.

The Geckos.

The Geckos form a large sub-order of lizards. Their chief characteristic is their adhesive toes, which enable them to cling to and run on smoothest surfaces even when upside down. They do not like the hot sunlight and largely feed at twilight and at night. The Reef Gecko is found in Florida; the Warty Gecko, so called on account of the rows of large wart-like scales on its back and sides, inhabits Lower California; the Cape Gecko, Lower California; the Banded Gecko, Texas, New Mexico, Arizona and California. The latter is the most gaudily marked of the Geckos found in the United States and is likewise the most abundant. It may be seen at dusk coming out of rock crevices to feed on small insects. Many consider this lizard poisonous and its saliva is supposed to produce painful skin eruptions. Authorities, however, tell us that this is not so. The first three Geckos mentioned live largely in trees, but the Banded Gecko lives on or near the ground.
