The Jumping Mouse (Zapus hudsonius) is a N. American, jerboa-like mouse, with long hind legs, a very long tail, and five complete toes on the hind foot. It is warmly reddish above, white on the lower parts, and progresses, when alarmed, by a series of rapid leaps, each of several yards, when in haste. it dwells in open, grassy places, skulking about under the herbage and feeding mostly on grass seeds; there it places its nest (a hollow ball of grass) in some small hole or burrow, and spends the cold months in a long hibernation.

The Common Kusimanse has a vaguely weasel-shaped body with dark brown fur that is thick, with a wiry texture down the back, and fine and soft on the underside. It has short legs, a short, relatively stiff tail, long claws, small ears, small, dark colored eyes, and an elongated nose.

Lemmings are small rodents, usually found in or near the Arctic, in tundra biomes. Together with the voles and muskrats, they make up the subfamily Arvicolinae (also known as Microtinae), which forms part of the largest mammal radiation by far, the superfamily Muroidea, which also includes the rats, mice, hamsters, and gerbils. Lemmings do not hibernate through the harsh northern winter. They remain active, finding food by burrowing through the snow and utilising grasses clipped and stored in advance. They are solitary animals by nature, meeting only to mate and then going their separate ways, but like all rodents they have a high reproductive rate and can breed rapidly in good seasons.

A lemming is a small, yellowish-brown rodent, closely related to the vole, and belonging to the genus Myodes. The Norwegian lemming (M. lemmus) is about five inches in length, with the tail extremely short. It excavates shallow burrows in the soil of the mountain meadows in which it lives, and in winter tunnels beneath the snow for its food, which is wholly vegetable, consisting of roots, shoots, catkins, moss, and lichens. Special interest attaches to this rodent from the fact that at irregular intervals, varying from five to twenty years, it suddenly appears in vast numbers in Northern Europe; great bodies, said to number millions of individuals, migrate from place to place in search of food, leaving behind them a track of desolation as they eat their way through fields of corn and grass. They show a remarkable persistency both in the act of migration and in the general direction of the movement, and swim without hesitation any bodies of water which may block their path. As, from the contour of the Scandinavian peninsula, they inevitably come eventually to the sea, those which have not perished from overcrowding, from disease, or from the attacks of their enemies, die in attempting to swim across it. The lemming of Northern Europe is known is replaced in North America by the allied M. obensis and the banded lemming (Cuniculus torquatus); the latter is circumpolar, and turns white in winter. Other allies, called lemming-mice, inhabit Northwestern Canada, and have somewhat similar habits, but rarely, if ever, migrate from their habitat.

"Loris is a genus of Lemurid&aelig;, with rounded heads and pointed snouts, slender bodies, very large eyes, and rudimentary tail or none at all.

A lynx is any of four medium-sized wild cats. All are members of the genus Lynx, but there is considerable confusion about the best way to classify felids at present, and some authorities classify them as part of the genus Felis. The Caracal, despite sometimes being called Persian Lynx or African Lynx, does not belong to this genus. Lynx have short tails and characteristic tufts of black hair on the tip of the ears. They have a ruff under the neck, which has black bars (not very visible), resembling a bow tie. They have large paws padded for walking on snow and long whiskers on the face. The body color varies from medium brown to gold-ish to beige-white; and occasionally, is marked with dark brown spots, especially on the limbs. All species of lynx also have white fur on their chests, bellies and on the insides of their legs which are extensions of the chest and belly fur. Also, the lynx's coloring, fur height and paw size varies by its climate range- in the Southwest US, the fur and color are short-haired, dark and the paws are smaller and less padded, as the lynx ranges to its colder Northern climes, the fur gets progressively thicker (for warmth), the color gets lighter (for camouflage) and its paws enlarge and become more padded for snowy environments.

The American marten (Martes americana) is a North American member of the Mustelidae family, sometimes referred to as the Pine Marten. The term Pine Marten is also used to refer to a separate Martes species from Europe. It differs from the fisher (Martes pennanti) in that it is smaller in size, has a pelage which is usually brown with an irregularly shaped chest-patch that is lighter in color.

"Megatherium is a genus of extinct edentates, founded on a nearly complete skeleton discovered on the banks of the Lujan, about 9 miles from Buenos Ayres, and sent by the Marquis of Loretto, the viceroy, to the Royal Museum of Madrid. The best-known species was nearly as large as an elephant, though the limbs were shorter. Its mounted skeleton measures 18 feet in length, of which the tail occupies five. Dr. Leidy has described a smaller species from the post-Tertiary of Georgia and South Carolina; and there is a third, founded on remains from Brazil."&mdash;(Charles Leonard-Stuart, 1911)

Moles are the majority of the members of the mammal family Talpidae in the order Soricomorpha. Although most moles burrow, some species are aquatic or semi-aquatic. Moles have cylindrical bodies covered in fur, with small or covered eyes; the ears are generally not visible. They eat small invertebrate animals living underground. Moles can be found almost anywhere in North America, Europe and Asia, although they are not found in Ireland.

"Spider Monkey is a general name applied to many species of platyrhine or New World monkeys, distinguished by the great relative length, slender-ness, and flexibility of their limbs, and by the prehensile power of their tails. A familiar species is the chameck, which occurs abundantly in Brazil. The body is about 20 inches, the tail 2 feet long, and the color is a general black. The coaita, another typical species, has an average length of 12 inches; the tail measures over 2 feet long, and the fur is of a glossy black hue."&mdash;(Charles Leonard-Stuart, 1911)

"The Orang Outang is the Mias of the Dyaks; also known as the 'wild man of the wood.' It is a dull, slothful animal, but possessed of great strength. These animals are now confined to the swampy forests of Sumatra and Borneo. Their height has been variously stated, but we have not the least reliable evidence of the existence of orangs in Borneo more than four feet two inches high. The legs are very short, the arms are disproportionately long, reaching to the ankle when the animal is placed in an erect position. The males have a longish beard, and they sometimes develop warty protuberances on each side of the face. The resemblance to man in appearance is greatest in the females and in young animals. The head of a baby orang is not very different from that of an average child; but in the adult the muzzle is as well-marked a feature as in the Carnivora. It never walks erect, unless when supporting itself by branches."&mdash;(Charles Leonard-Stuart, 1911)
