The fauna, however, has not attained to the same exceptionally fine development as the flora. At Rawak the phalanger and the sheepdog in a wild state were the only quadrupeds met with. In Waigiou, the boar called barberossa, and a diminutive of the same race were found. But as to the feathered tribe, they were not so numerous as one might have supposed; the plants yielding grain necessary for the sustenance of birds not being able to thrive in the dense shade of the forests. Hornbills are here met with, whose wings, furnished with long feathers separated at the tips, make a very loud noise when they fly; great quantities of parrots, kingfishers, turtle-doves, piping-crows, brown hawks, crested pigeons, and possibly also birds of paradise, though the travellers did not see any specimens. The Papuans themselves are positively repulsively ugly. To quote the words of Odet-Pellion, "a flat skull, a facial angle of 75 degrees, a large mouth, eyes small and sunken, a thick nose, flat at the end and pressed down on the upper lip, a scanty beard, a peculiarity of the people of those regions already noticed, shoulders of a moderate size, a prominent belly, and slight lower limbs; these are the chief characteristics of the Papuans. Their hair both in its nature and mode of arrangement varies a good deal. Most commonly it is dressed with great pains into a matted structure not less than eight inches in height; composed of a mass of soft downy hair curling naturally; or it is frizzed up, till it positively bristles, and with the assistance of a coating of grease, is plastered round the skull in the shape of a globe. A long wooden comb of six or seven teeth is also often stuck in, not so much to aid in keeping the mass together as to give a finishing touch of ornament." These unfortunate people are afflicted with the terrible scourge of leprosy, which is so prevalent that at least a tenth part of the population are infested with the disease. The cause of this dreadful malady must be sought in the insalubrity of the climate, the miasma from the marshes, which are overflowed with sea-water every flood tide, the neighbourhood of the burial-places, which are badly kept, and perhaps also to the consumption of shell-fish which these natives devour greedily.
