FIG. 69.—WALRUS (Trichicus rosmarus); SEAL (Phoca vitulina).
FIG. 70.—INSECTIVORA.
1, Hedgehog (Erinaceus Europæus); 2, Mole (Talpa Europæus); 3, Shrew-mouse (Sorex araneus).
9. The Insectivora, such as the Mole, Hedgehog, and Shrew-mouse, (fig. 70), live entirely on insects, the Mole burrows for them in the earth, and the fore paws are so made as to dig out and throw the earth behind it, and it burrows in this way with the greatest rapidity. As it is nearly always beneath the surface of the earth, and consequently in the dark, so a sense of vision is not required, it is therefore blind, but the senses of touch and smell, being very acute enable it to find its food. The Hedgehog and Shrew-mouse are furnished with pointed noses, with which they dig up the earth in search of insects, and when found they devour them with amazing rapidity. The Hedgehog has the power of rolling itself up into a ball and defying the attacks of almost anything, for its bristles are so stiff and sharp that they prick like thorns, and make a capital defensive armour; the Hedgehog is eaten by many, especially by the Gipsies, who esteem it a dainty.
FIG. 71.—BATS (Plecotus auritus).
10. The Cheiroptera (Bat tribe, fig. 71), have fore feet so modified as to serve as wings, with which they fly with tolerable swiftness, producing a peculiar flapping sound. These wings are formed by a membrane which is stretched out between the fingers, which are exceedingly elongated, and which reaches from the fore feet to the hind feet. The Bat tribe all feed upon insects, especially moths; they rest in the day time head downwards, clinging to rough places by means of the claws of their hind feet, coming out at night to seek their food; their sight, which is very quick, enabling them to see their prey when almost dark. Some of the larger species of this tribe, inhabiting America, are called Vampire Bats, they live by sucking the blood of various animals, such as cattle and horses, thereby inflicting dangerous wounds.
FIG. 72.—QUADRUMANA.
Baboons.—1. Mandrill (Papio maimon); 2. Chacma (Chacma Porcarius). Monkeys.—3. Mona (Cercopithecus mona); 4. Howler (Mycetes); 5. Spider (Ateles).
