The California Horned Lizard is found abundantly in sections of California.

[Ill.u.s.tration: HORNED TOAD.]

THE SNAKE-LIKE LIZARDS.

These lizards have elongated bodies with either small limbs or no external evidence of such. Some cannot be easily distinguished from snakes. On close examination it will be seen that there is a ridge along each side of the body.

The Keeled Lizard has a habit of keeping its tongue protruded and will wipe its lips with it after feeding. Its tail is easily separated from its body and when so separated, the broken off portion wriggles violently. New tails grow on. It is found in California, Oregon, Washington and eastward from California to Texas.

The "Gla.s.s-Snake" has no limbs and to the eye of anyone but a naturalist would easily be mistaken for a snake. What distinguishes it from a snake is the presence of eyelids and ear holes. It occurs in many localities.

It is common from the Carolinas to Florida and as far north as Illinois.

Like the Keeled Lizard it has the ability to shed a very lively, wriggling tail. It feeds on worms and slugs that it finds by burrowing and will occasionally break and eat the eggs of ground-nesting birds.

THE BEADED LIZARDS.

This is a family of large lizards whose bodies look as if covered with beads. They are held to be poisonous by well-known authorities and are the only poisonous lizards found in the states.

The Gila Monster (p.r.o.nounced Hee-la) has a thick body with short limbs and a short tail. In color it is pink and black. Its length is about a foot and a half. It is found in New Mexico and Arizona and is named after the river Gila, the valley of which it inhabits. The creature will defend itself viciously and will hold on tenaciously with its strong jaws. The eggs are buried in the sand.

XANTHUS LIZARDS.

Small lizards that are found where the tree yuccas grow.

THE RACE RUNNERS.

These are easily distinguished by the yellow stripes on their bodies.

They are to be found in the dry, sandy portions of the western states, burrowing in the sand and when pursued taking refuge in these burrows.

THE WORM LIZARDS.

These are a low grade of lizards that live underground like worms. The Worm Lizard, found in Florida, is scarcely any larger around than an earthworm. It is able to move backward or forward in the earth, the end of the tail being shaped similar to the head.

THE SKINKS.

This is a large family. They are burrowing lizards. The Red Headed Lizard is widely distributed throughout the United States. It is very timid and extremely difficult to capture. Its color changes with its age. The Black Banded Skink is found in the central portions of the United States. The Florida Skink in southern Florida. The Black Skink from Pennsylvania southward to Texas.

Here we reach the end of the order of reptiles known as lizards; the next order is that of the snakes.

THE SNAKES

THE OPHIDIA OR SNAKES.

Snakes are closely related to lizards. Some lizards, as you have already seen, are very much like snakes in form. The main distinguishing features of the snake are the elastic tissue which connects the two halves of the lower jaw and the absence of eyelids. Snakes are carnivorous and are capable of moving with great ease and swiftness notwithstanding their lack of limbs. They cast their skins several times a year. Many of the snakes are poisonous, and authorities tell us that there is no external characteristic that indicates which are poisonous and which are not.

THE BLIND SNAKES.

This is a low form of snake. They are worm-like and burrowing. The Texas Blind Snake is found in Texas and New Mexico. The California Blind Snake in California and Mexico.

THE BOAS.

The most common member of this family that comes within the range of this article is a snake that is found in the Pacific states and eastward as far as Nevada. It is over a foot in length and about half an inch in diameter. Various names have been given to it; in certain sections it is called the Rubber Boa, in others the Silver Snake, Two-headed Snake, Worm Snake. The name Two-headed Snake is given it evidently on account of the stubby appearance of the tail end.

THE RIBBON SNAKES.

These snakes have a yellow stripe along the back and the sides. They are long, slim snakes; specimens have been seen that measured nearly three feet long, although the average length is about two feet. It is found east of the Mississippi, but is not common. It frequents the banks of water to feed on young frogs and so forth. They swim well and are at home in the water. In the Western Ribbon Snake the back stripe is darker than those on the side, or in some instances a different color.

THE GARTER SNAKES.

These are found all over the United States and are perfectly harmless.

They are abundant. Burrowing in the ground in the late fall they remain there all winter. Even the boy living in the large cities may, without going out of the city limits, find these snakes. They are quite commonly found in large public parks. They like frogs and toads and bolt their food. There are many varieties of this snake. Both the Ribbon Snakes and the Garter Snakes belong to the genus Eutaenia, which is the most numerous of those of the United States. They are all striped snakes and are very much like the water snakes in structure. There is no easily distinguished characteristic that would enable a boy, at a glance, to tell a Garter Snake. They vary widely in color and marking.

THE WATER SNAKES.

Here is another genus of snakes that is found commonly in many sections of our country. They frequent the vicinity of water and swim with ease, feeding on frogs, toads, fish. The Queen Snake is found generally east of the Mississippi Valley. It is brown above and has yellow stripes on the side. The Banded Water Snake is the water snake which is commonly found in the southern part of the United States east of Texas. It closely resembles the Moccasin, a poisonous snake, and is often mistaken for it. It attains an average length of over a yard. When alarmed, like all the water snakes, it takes to the water for refuge. This genus never preys on birds or mice. It is one of the most common of the southern snakes. The Red-bellied Water Snake is found in the east, but not north of Virginia. The Common Water Snake is the northern representative of this genus. These snakes are popularly known as "Moccasins." The Diamond Back Water Snake is common along the lower Mississippi states. They average four feet in length. May be seen on low branches overhanging water. The Green Water Snake is similar in habit to the Diamond Back and is found in the Gulf and the Mississippi Valley states. One peculiarity of the water snakes is their love of their home. They pick out a particular sunning place and will return to it regularly.

THE GROUND SNAKE OR BROWN SNAKE.

This is a common snake, found all over the United States east of the Rocky Mountains. It is small in size, about a foot long and slender, and hides under stones, where it probably feeds on the worms and forms of insect life that live in such places.

THE RACERS.

The serpents of this type are very active and nervous. The Gopher Snake, or Indigo Snake, is one of the largest found in the United States. It has been known to measure over eight feet in length. It is found from Texas eastward in the Gulf states. Its scales have a polished appearance and are blue black in color. It may be seen in sandy stretches. When feeding it holds its prey down with part of its body. It is not particular as to its diet and will eat birds with the same relish as cold-blooded frogs and toads. In the Central and South American countries this snake is highly valued as a "ratter" and frequents human habitations without fear. The Black Snake is abundant in the United States. It has a bad reputation. It is said to be a fearless fighter, not afraid to attack man even, and to be able to "charm" its prey within its reach. These attributes are popular beliefs without any basis of fact. It is fond of small birds and field mice and is what may be called a meadow snake. When frightened it speeds away at an incredible rate.

The Coachwhip Snake, found in the southeast, is even more agile than the Black Snake, and like that serpent, will eat smaller snakes. It gets its name from its slender structure and similarity of the appearance of its scale distribution to a plaited whip. The Striped Racer of the southwestern states is very long and slender.
