Rodentia
or RODENTS, an order of mammiferous quadrupeds occupying in many respects an intermediate place between the purely carnivorous and purely herbivorous mammalia, and so forming the connecting link between them. The order embraces rats and mice, hares, rabbits, guinea pigs, and other well-known animals. These animals have two great incisor teeth in each jaw, separated from the molar by by a wide space, with which they could hardly seize a living prey or rend flesh, but could reduce them by gnawing, whence the term rodents, or gnawers, applied to this order. The characteristic of this order is that the lower jaw has no horizontal movement except from behind forward, and vice versa, convenient for the action of gnawing; the molars of the Rodentia, consequently, have flat crowns, the enameled eminences of which are always transversal, so as to be in opposition to the horizontal movements of the jaw, and to be better adapted for trituration. The hinder parts of the body of the rodents in general exceed their anterior. Some of them enjoy a certain dexterity, using their forefeet for carrying their food to their mouth; while others again (the squirrels) climb trees with facility. Rodents are most abundant in temperate regions. In North America there are 371 species, 19 genera; 81 species, 16 genera in Europe and the N. of Asia; in Africa, 53 species, 16 genera; in India and its islands, 58 species, 10 genera; in South America and West India Islands, 89 species, 25 genera.

Rodents
the order of gnawing animals. It includes the tree squirrels, chipmunks, ground squirrels, flying squirrels, prairie dogs, woodchucks, beavers, mice, rats, muskrats, lemmings, moles, jumping mice, pocket gophers, porcupines, hares, and rabbits. There are in all about 371 species of rodents. Of these, about 170 are found in North America . A rodent may be known by its front teeth. They have the shape of chisels and are designed to cut vegetable substances, gnaw shells of nuts, etc. The front portion of the tooth, or cutting edge, consists of the hardest enamel; the rear is softer and wears away more rapidly, leaving the front edge keen and sharp. The tooth grows as fast as it wears off. Many animals that resemble the rodents in appearance belong to other orders. The bats, for instance, look like mice; but they are not rodents. They have sharp teeth, instead, suited for eating insects and fruit. Moles and shrews also have sharp teeth. They are insect eaters, not rodents. A similar remark applies to the hedgehog of Europe. A systematic notion of American rodents may be had from the special articles on SQUIRRELS; CHIPMUNK; GROUND SQUIRREL; BEAVER; MOUSE; RAT; POCKET GOPHER; PORCUPINE; HARE; RABBIT. See also PRAIRIE DOG ; WOODCHUCK; FLYING SQUIRREL .
