The animal is of considerable size, and is covered with coa.r.s.e black hair--with the exception of the face, parts of which are of a tawny flesh-coloured hue. There are various species, each of which has its peculiar district; and they vary slightly in appearance.

In the neighbourhood of Obydos, the Ateles paniscus has its abode; while in the Upper Amazon the white-whiskered coaita (Ateles marginatus) takes its place. It is remarkable that animals which apparently have the means of moving without difficulty at a rapid rate in any direction should thus be confined to particular localities.

THE CHEMECK.

The chemeck appears to have a wider range. It possesses a thumb, slightly projecting, and furnished with a nail--though the thumb cannot be used like that of a human being, as it is incapable of being opposed to the fingers. It is a gentle creature, and capable of considerable cultivation. Although playfully inclined, it is seldom spiteful; while its disposition is very different from that exhibited by the capricious temper of the Old World monkeys. It soon learns to distinguish its friends; and will playfully pretend to attack them, but never does any real harm. It is covered with a long fur, which falls densely over the body; as is its tail, which at once distinguishes it from its relatives.

The ear is somewhat similar to that of man, but has no lower lobe. The nostrils open at the sides, and are separated by a wide piece of cartilage. The habits, however, of the ateles, are so similar, that they require no separate description.

Wandering through the forest with an Indian guide, we reach an igarape or stream, where the lofty branches of the trees do not completely meet overhead, but where the opening is as yet of no great width. Lying concealed, we hear a strange chattering and rustling among the foliage in the distance. Pieces of rotten wood, husks, and nuts come dropping down, and we may see the boughs alive with numberless dark-haired little creatures, their long lithe tails twisting and twirling, their active limbs stretched out in all directions, as they make their way through the forest. We recognise them as a troop of ateles, migrating to some other district, or on some expedition in search of food.

On reaching the boughs above the banks of the stream, they seem somewhat puzzled. Several of the elders of the tribe go to the outer ends of the boughs, and appear to be measuring the distance across. As they have an especial dislike to wetting their hairy skins--although they would undoubtedly swim if no other means could be found of getting to the opposite bank--they have devised a method more suited to their tastes.

They leap from bough to bough, till they find one projecting in a line with the trunk or branch of any tree inclining over the water from the opposite side. The larger and stronger members of the tribe now a.s.semble, leaving the younger ones to gambol and frisk about among the boughs, and amuse themselves in juvenile monkey fashion. One monkey-- the Hercules probably of the tribe--twisting his tail round the outer end of the branch, now hangs by it with his head downwards, at his full length. Another descends by the body of the first, round which he coils his tail. A third adds another link to the chain: and thus, one by one they increase its length, till the surface of the water is almost reached. The chain now begins to oscillate backwards and forwards towards the opposite bank, each movement increasing the length of the arc, till the lower monkey, with fore-arms outstretched, reaches the stem of the tree on the opposite bank. He grasps it tightly, gradually clambering up, and drawing the line composed of his comrades after him, till the monkey immediately below him is also able to seize the trunk, and a.s.sist in dragging up the rest. They thus form an almost horizontal bridge above the water. The rest of the agile tribe, now summoned from their sports, begin to cross; the younger ones, in the exuberance of their spirits, taking the opportunity of playing all sorts of pranks during their pa.s.sage over the bodies of their self-sacrificing elders-- giving many a sly pinch of the ear, or pull of the hair, for which they well know they cannot at the moment receive punishment. Thus the whole party--the mothers with their infants on their backs, and the other juvenile members--cross in safety, and a.s.semble among the branches to watch the further proceedings.

The great difficulty now appears to be for the individuals composing the bridge to get across without touching the water. Trusting to the muscular power of their tails and limbs, they appear in no way daunted.

The monkeys which have hitherto formed the lower links of the chain, still holding on by their tails to their friends, work their way up the trunk and along a branch of equal or greater height than that on the opposite side, to which the long-enduring Hercules has. .h.i.therto clung.

On their attaining the point selected, he at length unwinds his tail, and swings downwards--with a force which seems sufficient to dislocate the limbs of those holding on above--and now becomes the lowest in the line. The force with which he has descended enables him to swing towards the side which his comrades have reached, and to grasp the trunk, up which he also climbs, till his neighbour can catch hold of it.

He follows his example, till all, one after the other, have grasped it: and thus they perform an operation which the most renowned of human athletes would find it difficult to imitate.

A troop will cross a gap in the forest in the same way, rather than venture down from the leafy heights they find it safest to occupy. When compelled to descend to the ground, they scuttle over it in the most awkward manner--their long limbs straggling out, and their tails in vain seeking some object to grasp. On these occasions the spider-monkey turns its hind-feet inwards, and thus walks on the outer sides, while the fore-paws are twisted outward; thus throwing the whole of its weight upon their inner edges. It is when thus seen that the appropriateness of the name given to it is more especially observed. When hard-pressed, however, the knowing little animal, finding no bough round which to coil its tail, rears itself up on its hind-limbs, and balances itself by curling up its tail in the form of the letter S, as high as its head; thus--by altering the centre of gravity--being enabled to got over the ground in a posture such as no other member of its tribe can maintain.

It will thus run on towards some friendly stem or low-hanging bough, which it seizes with its lithe and prehensile limb, and joyfully swings itself up in its usual monkey fashion, quickly disappearing amid the foliage.

The ordinary size of the coaita's body is about a foot from the nose to the root of the tail, while the tail itself is rather more than two feet in length.

MACACO BARRIGUDO.

Seated among the boughs may often be seen, in the forests of the Upper Amazon, a number of large, stout-bodied, fat-paunched monkeys, with long flexible tails, furnished underneath with a naked palm, like the hand, for grasping. Their faces are black and wrinkled, their foreheads low, and eyebrows projecting; their features bearing a wonderful resemblance to those of weather-beaten old negroes. The heads of some are covered with black hair, and others with grey. They are called by the Portuguese _macacos barrigudos_, or big-bellied monkeys. They belong to the species of Lagothrix, and are closely allied to the coaitas. They are bulky fellows, and though able, by means of their prehensile tails, to get along at a good rate among the boughs, seldom trouble themselves to move rapidly.

With the exception of the black howler, which will be described anon, they are the largest monkeys in America--their bodies measuring about twenty-eight inches in height. Their flesh being highly esteemed by the natives, they are unceasingly hunted by the Indians. Though their manners are somewhat grave, yet, from their mild and confiding temper similar to that of the coaitas--they are much sought after for pets.

They live exclusively on fruits.

THE UAKARI.

On the western side of the River Yapura, near where it pours its waters into the Amazon--a forest region inundated during the greater part of the year--there lives in small troops, high up among the crowns of the lofty trees,--where it feeds on fruits of various descriptions,--a small, almost tailless monkey, its face glowing with the most vivid scarlet hue. Its body, about eighteen inches in height, exclusive of limbs, is clothed from head to tail with very long, straight, shining, whitish hair. Its head, nearly bald, is sprinkled over with a short crop of thin grey hair; whilst round its ruddy countenance, bushy whiskers, of a sandy colour, meet under the chin. It has reddish-yellow eyes. It belongs to the Cebidae family. The Indians call it the white uakari. It inhabits, as far as is known, no other district.

In spite of its want of tail, it is an active little creature, running up and down the larger branches, but seldom leaping from one to the other. The mothers, as is the custom with the other monkey orders, carry their young on their back. They are highly valued as pets; but being of a delicate const.i.tution, seldom live long when transported from their native district.

The native hunter, on wishing to obtain one of these creatures alive, goes forth with his blow-pipe, and arrows tipped with diluted wourali poison. This poison, though producing so deadly an effect on animals, as well as human beings who exist without salt, appears to have little or no effect on salt-consuming Europeans. Salt, indeed, is the great antidote to the poison. The hunter, in consequence, supplies himself with a small quant.i.ty of salt. As soon as he has shot a monkey, he follows it through the forest, till, the poison beginning to take effect, it falls exhausted into his arms. He then immediately puts a pinch of salt in its mouth, and in a short time the creature revives, and is led away captive. If old, however, when thus caught, it appears to be discontented in confinement, and, seldom becoming tame, in a short time pines away and dies. When a young one is thus caught, it frequently becomes a playful and interesting pet, and is highly valued by the Brazilians.

Further to the west, an allied species of this monkey is found, clothed with red instead of white hair; while, at a still greater distance, a black-faced and grey-haired species takes the place of the two former.

ALOUATTES, OR HOWLERS.

The voyager up the Amazon, or one of its numerous tributaries, when his montaria has been moored to the banks, a fire lighted to keep prowling jaguars or pumas at a respectful distance, his hammock hung up in his temporary hut, and he is expecting to enjoy a quiet night's rest, is, ere long, often awoke by the sound of the most fearful howling proceeding from the recesses of the forest. Now it sounds like the dreadful roar of the jaguar as it springs on its prey. Now it changes to the terrible and deep-toned growlings of the wild beast as he is pressed on all sides by his foes, and now it seems like his last dying moan beneath a mortal wound. Nothing can be more dismal or dispiriting than the fearful uproar. Hour after hour it goes on during the night, increasing as the dawn approaches. Now the howls come from one direction, now from another, and in far-off parts of the forest. Yet, terrific as they appear, they are produced by animals not much larger than a full-grown fox. It is the mycetes, or ursine howler--the largest monkey of South America.

On advancing into the forest in the morning, three or four may be seen seated on the upper branches of a tree--s.h.a.ggy-haired animals, with long prehensile tails like those of the spider-monkeys--hideous-looking creatures, with pyramidical heads, the upper jaw descending much below the cranium, while the branches of the lower one ascend very high, for the purpose of containing a bony, drum-shaped expansion of the larynx, which gives to its voice that prodigious volume of sound which makes night hideous.

They differ somewhat in colour. Some are entirely black, others brownish-black, while the Mycetes ursinus is of a shiny yellow.

These unmusical howlings are supposed by some naturalists to be merely the nocturnal serenades of lover mycetes addressed to their mistresses, seated high on the branches in some distant part of the forest; others regard them rather as noises which serve to intimidate their enemies, though not emitted in general for any sudden alarm.

The female howler carries its young on its back. It is the least attractive in appearance of its western brethren, and is the only one of the monkey tribe which the natives are unable to tame. Though often caught, they do not survive many weeks in captivity. It lives on fruits and nuts, and is hunted for the sake of its flesh, which, though rather dry, is much esteemed. The natives entrap this monkey in a curious fashion. They take a large nut, and sc.r.a.ping out the interior, leave only a small mouth, and, filling it with sugar, leave it near the trees inhabited by the mycetes. The inquisitive monkey soon descends to examine the nut, and putting in his hand, grasps the sweet contents.

Knowing that it is well-suited to his taste, he will not let go, but runs off with his prize, which greatly impedes his progress. Although he might easily draw out his hand by opening it, this he does not think of doing; and thus, unable at the best to move rapidly over a level surface, is soon overtaken by the hunter, and captured.

THE CUXIO (BEARDED SAKI).

Among the host of curiously-shaped, long-tailed, active little monkeys which inhabit the American forests, the cuxio is one of the most remarkable. Its general colour is a grizzly-brown; but the head, limbs, and tail, are black. As the pa.s.ser-by sees the odd little creature gazing down on him, he might fancy that it had just escaped from the hands of the _perruquier_. The black hair of its head is parted carefully on either side. Its enormous black beard seems as if just freshly dressed; while its bushy tail looks as if equally cared for.

Notwithstanding its somewhat fierce and Turk-like visage, it lives a respectable, domestic life, with one partner alone--the sharer of its home--engaged in the task of rearing its infant progeny.

She is not of so dark a colour as her mate, her hair being chiefly of a rusty-brown.

The odd little creature's head is of a round form, and considerable size, greatly increased in appearance by the amount of hair which surrounds it. The nostrils are wide, and divided by an unusually large cartilage. It is furnished with large jaws, and teeth so sharp that it has been seen to drive them, when angry, into a thick plank. When in a rage it grinds them together, and, rubbing its long beard in a most curious way, leaps about in every direction. At the slightest cause of offence, it gives a savage grin, wrinkling the skin of its face and jaws, and threatening the offender with the most menacing grimaces.

It seems perfectly conscious of the unusual adornment of its head, treasuring its bushy beard with as much care and pride as does a human exquisite. When drinking, it dips its paw, curved into the shape of a spoon, into the water, and thus brings the liquid to its mouth. The natives declare that it does so to avoid the risk of wetting its long beard, of which--being generally dest.i.tute of such appendages themselves--they fancy it must be excessively vain. As it is chiefly nocturnal in its habits, it might be cla.s.sed among the Nyctipitheci, or night monkeys. From its fierce countenance, long, sharp teeth, and savage temper, it has gained its second scientific name--Brachyuras Sata.n.u.s.

THE CACAJAO.

The cacajao is a curious contrast to the cuxio. It is called also the black-headed saki. Unlike most of its brethren, it has but a short, hairy tail, looking as if it had been docked. The head is perfectly black, somewhat flattened at the temples, with large ears approaching in shape to those of the human head, and devoid of hair. The fur on the body is generally of a bright yellowish-brown. When full-grown, the animal reaches to upwards of twenty inches in length, while the tail is from three to five inches long. Its legs are covered with rough hair, and its fingers are unusually long and slender, giving it an awkward appearance when feeding. In captivity it is a docile and peculiarly timid animal. A little creature which had been caught exhibited great alarm at the appearance of several small monkeys of its own country; and when a serpent was placed before its eyes, it trembled violently.

It is found on the borders of the Negro, where it is known by several names--among others, as the mono faio, or ugly monkey.

MARMOSETS, OR MIDAS MONKEYS.

The most active, playful, and amusing of animals are the midas monkeys, which form the second family of American Quadrumana, several species of which exist, each in its respective district. As they are seen gambolling among the branches,--now running round and round the trunk of a perpendicular tree, now with their sharp claws rapidly mounting the branches, sending down showers of rotten bark and twigs, and uttering sharp twittering cries,--they might be mistaken for a troop of squirrels.

They are restless, inquisitive little creatures, possessed of a large share of curiosity. When a stranger is pa.s.sing through the forest, they invariably stop for a few moments to have a stare at him.

Though in no way related to squirrels, which belong to the rodent order, they may easily be mistaken for them at a distance. They are all of small size, and very similar, in their mode of climbing, to squirrels.

Their nails, also, except those of the hind-thumbs, are long and claw-shaped; and the thumbs of the fore extremities, or hands, are not opposable to the other fingers. Their bodies are long and slender, clothed with soft hair; and their tails, though not prehensile, are nearly twice the length of their bodies.

MIDAS URSULUS.

The midas ursulus is found in the Lower Amazon, frequently in the neighbourhood of towns, and it seems much less afraid of man than most other monkeys. It is seldom that more than three or four individuals are seen together. It moves generally among the larger boughs and trunks of trees, its long nails a.s.sisting it to cling securely to the bark.

It lives on both animal and vegetable food; the former including various insects, eggs, and occasionally a young bird--while its vegetable diet consists of all the sweetest fruits it can find. The smaller insects-- flies, and other soft-bodied creatures--it pops into its mouth whole; but when eating a larger one--such as a c.o.c.kroach--it nips off the head, wings, and legs, before putting it into its mouth.

It has gained the name of oust.i.ti, in consequence of its giving vent to a little sharp whistle when alarmed or irritated; but it otherwise generally preserves silence.

The midas ursulus is about nine inches long; and the tail measures fifteen inches. It is clothed in a thick, long fur, and has a reddish-brown streak down the middle of the back.

It is often seen in the houses at Para, and when treated kindly becomes very tame and familiar. When, however, strangers approach it, its dark, watchful eyes, expressive of distrust, observe every movement which takes place.

MIDAS LEONINAS, OR JACCHUS ROSALIA.

Another species, the Midas leoninas, or Jacchus Rosalia, inhabits the Upper Amazon. It is only seven inches in length. It is so named on account of the long brown mane which hangs from the neck, and gives it very much the appearance of a diminutive lion.

One of these little creatures, kept tame, became familiar with every one, and used to climb up the chairs, over their shoulders and heads, just as a squirrel does. Mr Bates relates that one he met with, having reached his shoulder, looked into his face, showing his little teeth, and chattering, as though it would say, "Well, and how do you do?" It exhibited more affection towards its master than to strangers, and would climb up to his head a dozen times in an hour, and make great show of searching for certain animalcule.

Audubon the naturalist possessed a little creature of this species, which could distinguish different objects depicted in an engraving. On showing it the portrait of a cat and a wasp, it became much terrified; but when the figure of a gra.s.shopper or beetle was placed before it, it precipitated itself on the picture, as if to seize them.
