Linné has given the name of _Lemurs_, which modern naturalists have also adopted, to a race of quadrumanous animals approximating in many particulars to the Monkey tribe, but forming, nevertheless, a perfectly distinct zoological family. It comprises five genera: one, that of the Galagos, belongs to Africa; two inhabit India and the neighbouring islands--namely, the Loris and the Tarsii; and, finally, two others, the Makis and the Indris, are exclusively confined to Madagascar, where they occupy the same position as the Apes properly so called on the continent. The Galagos are distinguished by their great eyes, their large membranous ears, which double down when the animal is at rest, their extraordinary long hind limbs, and their long and tufted tail. In size they vary from that of a rat to that of a rabbit. The _Senegal Galagos_, or Gum animals of Senegal (_Galago Senegalensis_), have, at night, all the activity of birds, hopping from bough to bough on their hind limbs only. They watch the insects flitting among the leaves, listen to the fluttering moth as it darts through the air, and leap upon it with arrow-like rapidity, seldom missing their prize, which is caught by the hands. Their nests are made in the branches of the trees, and they cover a bed for their young with grass and leaves. What shall I say of the _Loris_? Two species only are known, and both are natives of the East Indian world: the Short-limbed Loris (_Lemur tardigradus_), and the Slender Loris (_Lemur gracilis_), the latter being readily recognized by the disproportionate length of his limbs, and, especially, of his fore-arms. They live in the trees; feeding on insects, or, as a relish, on small birds and quadrupeds; and going forth at night in search of their prey. They have a short muzzle, slender body, no tail, rough tongue, and large staring eyes, placed very near each other. Their ears are short, scarcely rising through the hair in which they are embedded; the nostrils project beyond the mouth, and are surrounded by a naked muzzle; and the thumbs are widely separated from the fingers, both on the fore and hinder hands. Of the _Tarsii_ it is enough to say that they are insectivorous, like the loris, and that their hind limbs are similarly disproportionate. The tail is long and tufted; the large, fixed, glaring eyes mark them out as addicted to nocturnal habits. They leap about two feet at a spring, and by day conceal themselves under the roots of trees. Two species are distinguished: the _Tarsius fuscomanus_ of Fischer, and the _Tarsius bancanus_ of Horsfield.
