There is still much discussion concerning the limitation of the term Papuan as applied to people, and even whether it should not be dropped altogether, as Professor Sergi suggests. The Italian anthropologist extends the term Melanesian not only to comprise the natives of all the Western Oceanic islands, including New Guinea and the adjacent islands, but also Australia. At present I adhere to what Mr. Ray and myself[10] have considered to be the most convenient course, and to employ the term Papuan for what appear to be the autocthones of New Guinea. By Melanesians we understand the present inhabitants of the great chain of islands off the east of New Guinea, and extending down to New Caledonia. These terms are used to designate peoples, not races; neither are pure races, and at present we are unable to gauge the amount of race mixture in either, or even to state precisely what are their components.
From the boundary of Netherlands New Guinea to Cape Possession on the eastern coast of the Papuan Gulf, and inland from these coasts, the natives are dark, frizzly-haired Papuans; typically they are a dolichocephalic people, and rather short in stature.
The Papuans also occupy the greater part of the south-east peninsula of New Guinea; but along the southern coast-line, almost uninterruptedly from Cape Possession to the farthest island of the Louisiades, is an immigrant Melanesian population, about whom I shall have more to say presently.
I will now enumerate a few facts which will clearly bring out the essential distinction between these two peoples.
We have not at present a sufficient amount of data on the physical characters of the two peoples by skilled observers to enable us to formulate what differences there may be between them. There is no doubt that the Papuans are more uniformly dark than are the Melanesians (I am now referring solely to the Melanesians in British New Guinea), and their hair is as constantly frizzly. Among the Melanesians light-coloured people are constantly met with, as are also individuals with curly and occasionally straight hair. Their skulls exhibit many variations, and are occasionally brachycephalic. Judging from my experience of the Western Papuans, the Papuan men usually sit with their legs crossed under them like a tailor, whereas the Melanesians squat, like a Malay, usually with their haunches just off the ground. I do not know whether this rule holds good for the Papuans of the south-east peninsula.
The Western Papuans may or may not scarify their skin, as in Torres Straits, but they do not tattoo; the Melanesians tattoo themselves, especially the women. Tattooing has, however, spread to a certain extent among the Papuan hill tribes of the peninsula; the Koitapu women appear to have thoroughly followed the fashion of their Motu neighbours; amongst the Koiari and other hill tribes it occurs only occasionally. The V-shaped chest mark gado (Fig. [20]) occurs among the Motu and Loyalupu, but not east of Keppel Bay. Among the two former the tattooing lacks symmetry, but in Aroma curved lines become more frequent and asymmetrical figures have a bilateral symmetry with regard to the body.
The houses of the Gulf and Western Papuans are often of great size and contain numerous families, and there appears to be more club-life among the men. The houses of the Melanesians are smaller, each family possessing one; those in the Trobriand Group are not built on piles. Very characteristic of the Papuans are the houses which are confined to the use of the men. These houses are the focus of the social life of the men, and as religion among savages is largely social usage, it is also in connection with these structures that most of their religious observances are held.
The initiation of lads into manhood is accompanied with sacred ceremonies in some of the Papuan tribes, but, so far as is known, by none of the Melanesians in New Guinea. Masks are usually, perhaps invariably, worn at these ceremonies, and the bull-roarer is swung and shown to the lads. There is no record of a bull-roarer among the Melanesian folk.
Masks are employed by many peoples during certain ceremonies; their distribution in New Guinea is interesting, as it will be found that in the British Possession they characterise the Papuan as opposed to the Melanesian elements. They were common in Torres Straits, have been obtained in Daudai, and are very abundant in the Papuan Gulf from Maclatchie Point to Cape Possession.
Dancing may be a secular amusement or a ceremonial exercise; in both aspects it is largely practised by the Papuans proper. We have very few accounts of dances among the Melanesians, and these do not appear to be of a specially interesting character.
