exclusively inhabitants of the latter, they may appropriately be noticed here.
The Lemurs are animals having very much the appearance and habits of monkeys, but with long snouts or muzzles, resembling that of the fox. Hence they are sometimes called fox-apes. There are many kinds of them, however; and, although classed in a group called lemurs, they differ exceedingly from one another, some of them having the appearance of foxes, others more resembling squirrels, and still others like flying squirrels – being possessed of a similar wing-like appendage, and capable, like them, of extended flight. They are known under different appellations, as Makis, Indris, Loris, Galagos, Tarsiers, Ay-ays, etcetera, and naturalists have subdivided them into a great number of genera. They are found both in Africa and Asia; but by far the greater number of them, as the Makis and Ay-ays, belong to the Island of Madagascar. The last are not to be confounded with an animal bearing the same name – the ay-ay of America. The latter is the singular creature known as the sloth, of which there are several distinct species, all inhabitants of the great forests of tropical America.
Of the lemurs, at least thirty different kinds are known, more than half of which belong to the Island of Madagascar. A few species are found on the west coast of Africa: and the others inhabit the Oriental islands – Ceylon, Java, Sumatra, Timor, Mindanao, and the Philippine Archipelago.

Monkeys of the New World
The Monkeys of America differ in many respects from those of the Old World. In general they are smaller – none of the species being quite so large as the baboons. Their bodies and limbs are also more slender and spider-like; and their whole conformation seems intended to adapt them for dwelling in the great virgin forests of the New World. There is one particular in which they differ most remarkably from their congeners of the Old World; that is, in having prehensile tails. With these they are enabled to suspend themselves from the branches of trees, or swing their bodies from one to the other; and this prehensile power is far greater than could be obtained by any clutch of the hand. So great is it, that even after the animal has died from the effect of a shot or other wound, its tail will still remain hooped around the branch; and if the body is not taken down by the hunter, it will hang there till released by the decay of the tail!
Not all the monkeys of America possess this prehensile power of tail. Some are entirely without it, and approach nearer to certain kinds in the Old World; while there are a few species that very closely resemble the lemurs. These differences have led to a classification of the American monkeys; and they have been thrown into three groups, though it may be remarked that these groups are not very natural.
They are as follow: – The Sapajous, whose tails are not only prehensile, but naked underneath, and tubercled near the tips; the Sajoas, who possess the prehensile power, but have hairy tails; and the Sajouins, whose tails are not prehensile.
For want of a better, this classification may be adopted.
The Sapajous are subdivided into three genera, of which the Howlers form one. They are so denominated from their habit of assembling in troops, and uttering the most terrible howlings, so loud that the forest is filled with their sonorous voices. Their cries can be heard at a half-league’s distance, and produce upon a stranger unaccustomed to such sounds a very disagreeable impression. The unusual strength of voice is accounted for by a peculiar drum-like construction of the os hyoides, common to all the genera of Sapajous, but more developed in some than in others; and those in whom the voice is loudest constitute the genus of Alouatles, or Howlers.
Of the true howlers there are about a dozen species known to naturalists. Most of them are denizens of the tropical forests of Guiana and Brazil; but some species are not so tropical in their habits, since one or two extend the kingdom of the monkeys into Mexico on the north, and southward to Paraguay.
Closely allied to the last, are the Ateles, or Spider monkeys. These derive their generic name from their singular spider-like appearance – caused by their disproportionately long and slender limbs, and the great length of their tails. None equal them in the prehensile power of the caudal appendage; and it is of them that that curious story is related – the story of the Monkeys’ Bridge – where it is told how they pass over a stream: a number of the strongest joining their bodies together by means of their long tails, and thus forming a bridge, by which the whole troop are enabled to cross.
Of the spider monkeys there are about a dozen species; but three of these have been taken to form one of the three genera into which, as already stated, the Sapajous are divided. These three differ very little from the other spider monkeys, except in being covered with a soft, woolly hair; and, furthermore, in being much more rare than the others; at all events, they are more rarely seen, as they dwell only in the thickest forests, far remote from the habitations of man.
The third and last genus of the Sapajous is that termed Lagothrix. They are small monkeys, covered also with soft woolly hair; and their habitat is along the banks of rivers. They have a strange habit, not observable among their congeners, of collecting in small troops, and rolling or “clewing” themselves up together. This they do in cold weather, or on the approach of a storm. They summon each other by means of signals and cries; and selecting the convenient bifurcation of some tree, they there form the singular group. The jaguar and other beasts of prey take advantage of this habit, and often make victims of the whole tableau vivant! There are three species already described, all denizens of the Brazilian forests.
The Sajous form the second group of the American monkeys. These have also prehensile tails; but the power is not so highly-developed in them as in the Sapajous, nor are their tails naked. Moreover, the bodies of the Sajous are more robust, and their limbs of stouter make.
The Sajous are well-tempered creatures, and easily domesticated. Some of the species are favourite pets – on account of their pleasing manners, and the docility of their nature. The old males, however, scarcely deserve this reputation, as they will bite freely enough when provoked.
They are not subdivided; but permitted to constitute a single genus, of which there are nearly twenty species – all of them inhabiting equatorial America.
The Sajouins form the third group; but as the name merely signifies those monkeys that have not the power of suspending themselves by the tail, it can hardly be considered a natural group, since there are very varied and numerous genera who lack this power. The group of Sajouins must therefore be subdivided into several lesser groups.
First of all we have the true Sajouins; and of these the Saimiri or Titi is the most distinguished species. This pretty little creature is about equal in size to a squirrel, and possesses all the playful disposition of the latter. Its childlike innocence of countenance, as well as its pleasing and graceful manners, render it a favourite pet wherever it can be obtained. Its rich robe of yellowish-grey, mixed with green, adds to the attraction of its presence. There are several species of Sajouins, known as the Widow monkey, the Moloch, the Mitred monkey, and the Black-handed Sajouin – all of them dwellers in the tropical regions of America. The Doroucouli is another small species, that in the nocturnal forest often alarms the traveller by its singular cry; and an allied species of Doroucouli constitutes, with the one above-mentioned, a second genus of the Sajouins.
The Sakis form of themselves another and somewhat extensive family of the Sajouins. There are a dozen species of them in all; and they possess the peculiarity of being insect-eaters. They are fond of honey, too; and are often seen ranging the woods, in little troops of ten or twelve, in search of the nests of the wild bees, which they plunder of their luscious stores.
The Ouistitis also constitute a genus. These, like the Saimiris, are beautiful little creatures – many of the species not being larger than squirrels, and marked with the most lively colours: as bright red and orange. There are many different kinds of small squirrels known by this name, or by its abbreviation – Titi – some of them belonging to the group of Saimiris, and others to the Ouistitis, properly so called.
Last of all come the little Tamunus; some of which, in beauty of colours, in playfulness of disposition, and other amiable qualities, need not yield either to the Saimiris or Ouistitis. They are equally prized as pets; and among their Creole owners have equally applied
