Characteristic are the giraffe, the chimpanzee and the ostrich.
It is probable that the Liberian chimpanzee may offer one or more distinct varieties; there is an interesting local development of the Diana monkey, sometimes called the bay-thighed monkey (Cercopithecus diana ignita) on account of its brilliant orange-red thighs.
Of this baby chimpanzee the skeleton may be seen in the Natural History branch of the British Museum alongside the volume in which it is described.
2, (a) gibbon; (b) orang; (c) chimpanzee; (d) gorilla; (e) man).
The elephant (though its range has become restricted through the attacks of hunters) is found both in the savannas and forest regions, the latter being otherwise poor in large game, though the special habitat of the chimpanzee and gorilla.
The wild animals include the elephant, still found in large numbers, the leopard, panther, chimpanzee, grey monkeys, antelope of various kinds, the buffalo, wild hog, bush goat, bush pig, sloth, civet and squirrel.
Till recently these apes have been generally included in the same family (Simiidae) with the chimpanzee, gorilla and orang-utan, but they are now regarded by several naturalists as representing a family by themselves - the Hylobatidae.
It was not, however, till 1788 that the chimpanzee received what is now recognized as a scientific name, having been christened in that year Simia troglodytes by the naturalist Johann Friedrich Gmelin.
In his classification it was included in the same genus as the orang-utan; and it has recently been suggested that the name Simia pertains of right to the chimpanzee rather than to the orang-utan.
The first of these aberrant types is Schweinfurth's chimpanzee (Anthropopithecus troglodytes schweinfurthi), which inhabits the Niam-Niam country, and, although evidently belonging to the same species as the typical race, exhibits certain gorilla-like features.
The celebrated ape "Mafuka," which lived in the Dresden zoological gardens during 1875, and came from Loango, was apparently a member of this species, although it was at one time regarded as a hybrid between a chimpanzee and a gorilla.
A gorilla-like feature in "Johanna" is, however, the presence of large folds at the sides (ala) of the nostrils, which are absent in the typical chimpanzee, but in the gorilla extend down to the upper lip. Chimpanzees exhibit great docility in confinement, where, however, they seldom survive for any great length of time.
In this picture, which shows the crudeness of the zoological notions current in the 18th century as to both men and apes, there are set in a row four figures: (a) a recognizable orang-utan, sitting and holding a staff; (b) a chimpanzee, absurdly humanized as to head, hands, and feet; (c) a hairy woman, with a tail a foot long; (d) another woman, more completely coated with hair.
While similar as to their general arrangement to the human brain, those of the higher apes, such as the chimpanzee, are much less complex in their convolutions, as well as much less in both absolute and relative weight - the weight of a gorilla's brain hardly exceeding 20 oz., and a man's brain hardly weighing less than 32 oz., although the gorilla is considerably the larger animal of the two.
Many naturalists hold the opinion that the anatomical differences which separate the gorilla or chimpanzee from man are in some respects less than those which separate these man-like apes from apes lower in the scale.
CHIMPANZEE (Chimpanzi), the vernacular name of the highest species of the man-like apes, forming the typical representatives of the genus Anthropopithecus.
In height the adult male chimpanzee of the typical form does not exceed 5 ft., and the colour of the hair is a full black, while the skin, especially that of the face, is light-coloured; the ears are remarkably large and prominent, and the hands reach only a short distance below the knees.
From this appears that Battel was familiar with both the chimpanzee and the gorilla, the former of which he terms engeco and the latter pongo - names which ought apparently to be adopted for these two species in place of those now in use.
Between the typical West African chimpanzee and the gorilla there is no difficulty in drawing a distinction; the difficulty comes in when we have to deal with the aberrant races, or species, of chimpanzee, some of which are so gorilla-like that it is by no means easy to determine to which group they really pertain.
Many naturalists regard the gorilla as best included in the same genus as the chimpanzee, in which case it should be known as Anthropopithecus gorilla, but by others it is regarded as the representative of a genus by itself, when its title will be Gorilla savagei, or G.
The forests are the home of several kinds of monkeys, including the chimpanzee in the Aruwimi region; the lion, leopard, wild hog, wolf, hyena, jackal, the python and other snakes, and particularly of the elephant.
