Part 66

Fur long and woolly over the body; especially long on the top of the head, forming a crest; hair of the limbs shorter.

{282}Face, neck, hands, and feet black; fur all over the body and limbs jet-black; callosities bright flesh-colour.

In the skull the maxillary bones are developed into strong lateral ridges corresponding in structure to those of the most typical Baboons.

DISTRIBUTION.--This species is found far away from the habitat of the true Baboons, whose home is in the Ethiopian Region. The Black Baboon is an inhabitant of Celebes, one of the islands of the eastern portion of the Malay Archipelago. It is found, however, also in the neighbouring island of Batchian, further to the east--indeed the most easterly range of the Quadrumana--as well as in some of the Philippine Islands to the west. In both of these regions it is supposed to have been accidentally introduced by the Malays. In Batchian, Mr. Wallace remarks, "it seems so much out of place that it is difficult to imagine how it could have reached the island by any natural means of dispersal, and yet not have passed by the same means over the narrow strait to Gilolo--so that it seems more likely to have originated from some individuals which had escaped from confinement, these and similar animals being often kept as pets by the Malays and carried about in their praus." Analogous to the distribution of this animal in the Philippines and Celebes is that of a genus of Parrots--Prioniturus--with racquet-shaped tails. The species of the latter genus are divided between Celebes and its small adjacent islands and the Philippines and the small islands adjacent to that archipelago, and present a curious case of the restricted range of a well-marked group.

HABITS.--This interesting animal, geographically so isolated, lives in the luxuriant forests in small companies, and feeds chiefly on the abundant fruits which these forests provide. In its {283}disposition it appears to be more amiable and docile than the African Baboons. Some kinds of Monkeys, as Mr. Darwin observes, which have moveable ears, and fight with their teeth, draw back their ears when irritated just like Dogs, and then they have a very spiteful appearance.... Other kinds--and this is a great anomaly in comparison with most other animals--retract their ears, "and utter a slight jabbering noise when they are pleased by being caressed. I observed this in the Cynopithecus niger.... With the Cynopithecus the corners of the mouth are at the same time drawn backwards and upwards, so that the teeth are exposed. Hence this expression would never be recognised by a stranger as one of pleasure. The crest of long hairs on the forehead is depressed, and apparently the whole skin of the head is drawn backwards. The eyebrows are thus raised a little, and the eyes assume a staring appearance. The lower eyelids also become slightly wrinkled; but this wrinkling is not conspicuous, owing to the permanent transverse furrows on the face." When enraged, the Cynopithecus niger depresses the crest of hair on its forehead, and shows its teeth; "so that," as Mr. Darwin continues, "the movements of the features from anger are nearly the same as those from pleasure; and the two expressions can be distinguished only by those familiar with the animal." See the figures in Mr. Darwin's "Emotions in Man," &c., p. 136.

{285}APPENDIX.

While this volume was passing through the press, a valuable paper by Messrs. Oldfield Thomas and Ernst Hartert has appeared in the Hon. Walter Rothschild's Journal "Novitates Zoologicæ." It deals with the Mammalia collected in the Natuna Islands by Mr. Alfred Everett, and the following additional notes must be recorded.

p. 20. TARSIUS TARSIUS.

Tarsius spectrum, Oldfield Thomas and Hartert, Nov. Zool., i., p. 655 (1894).

Mr. Everett says that on Banguran Island he could hear nothing of the existence of the Tarsier, but on Sirhassen Island the Malays described it to him unmistakably under the name of "Imbing."

p. 33. NYCTICEBUS TARDIGRADUS.

Mr. Everett procured specimens of the Javan Slow-Loris on the island of Banguran, where, he says, it is probably not rare, though not often captured; the native name is "Kukáng." The natives of Banguran did not appear to know the animal.

p. 100 et sequent. PROPITHECUS MAJORI.

Propithecus majori, Rothschild, Nov. Zool., i., p. 666, pi. xiv. (1894).

{286}ADULT.--Head and neck black. Face, snout, and ears naked, and of a blackish colour, encircled by a broad band of long white hairs, joining under the throat, slightly mixed with darker hairs. Rest of fur, including the tail, white on the upper surface; back and upper rump dark brown. The large white patch on and between the shoulders much grizzled with brown hairs. Under side of hind-limbs, to just below the knees, blackish-brown. Inside of hind-limbs down to the heel also brown, joining the colour of the upper surface, thus forming a continuous dark stripe along the legs. Inner and upper surface of arms, thumb, and two following fingers, deep blackish-brown; throat, chest, and greater part of abdomen, deep brown. Size perceptibly larger than that of Propithecus verreauxi, with the tail longer.

This species of Propithecus is nearest to the typical P. verreauxi of Grandidier, which is white, with the top of the head black, and the lower back and rump greyish-brown, but is no doubt an entirely different species. (Rothschild, l.c.)

DISTRIBUTION.--Antimosy country, S.W. Madagascar.

"The 'Naturalist's Library' has all the signs of earning and keeping a wide popularity."--Scotsman.

"They are carefully compiled from the most authentic sources of information, and are embellished with cleverly-executed coloured plates."--Daily News.

"Admirable in every way, and should be highly popular."--Public Opinion.

"Really good handbooks, well arranged, concise, carefully printed, and handsomely illustrated with full-page coloured plates."--Science Gossip.

"Eminently readable, the information being given in an interesting manner."--Field.

"A most valuable feature of these volumes is the plates, which have been coloured from specimens in the British Museum, and are by far the finest that have ever appeared in any work at the price, or anything near it. Altogether the character and general get-up of 'Allen's Naturalist's Library' leave nothing to be desired. We trust these volumes, and those that may come after them, will be widely welcomed."--Westminster Gazette.

"Should prove most instructive to every student of natural history."--Rod and Gun.
