The front teeth were of great beauty, and were not set, as in most jaws, on a more or less marked curve, but were almost on a straight line—the incisors being almost absolutely vertical and meeting the side teeth at an angle of about 60°. The upper teeth overlapped the lower ones.
The chin was well developed—square and flattened in the Papuan types, but receding, flat and small in the Malay types.
Both types were absolutely hairless on the face and body, which was partly natural and partly due to the tribal custom of pulling out carefully, one by one, each hair they possessed on the upper lip and upon the body—a most painful process. The women—as we shall see—in sign of deep mourning, also plucked out each hair of the scalp.
A striking characteristic of the head—in Papuan types—was the great breadth of the maximum transverse of the head, and the undue prominence of the supra-orbital ridges. Also, the great height of the forehead and its great width in its upper part were typical of the race. The maximum antero-posterior diameter of the skull was equal, in many cases, to the vertical length of the head, taken from the angle of the jaw to the apex of the skull.
The ears nearly invariably showed mean, under-developed lobes, but, strangely enough, were otherwise well shaped, with gracefully defined and chiselled curves. They were not unduly large, with a wonderfully well-formed concha, which fact explained why the acoustic properties of their oral organs were perfect. They made full use of this in long-distance signalling by means of acute whistles, of which the Bororos had a regular code.
The favourite form of earring adopted by the Bororos was a brass ring with a metal or shell crescent, not unlike the Turkish moon, but I do not think that this ornament was of Bororo origin. Very likely it was suggested by the cheap jewellery imported into Brazil by Turkish and Syrian traders.
They displayed powerful chests, with ribs well covered with flesh and muscle. With their dark yellow skins they were not unlike beautiful bronze torsi. The abdominal region was never unduly enlarged, perhaps owing to the fact that their digestion was good, and also because they took a considerable amount of daily exercise. In standing they kept their shoulders well back, the abdominal region being slightly in front of the chest. The head was usually slightly inclined downwards.
The feet of the Bororos of the Malay type were generally stumpy, but this was not so with the higher Papuan types, who, on the contrary, had abnormally long toes and elongated feet, rather flattened. The Bororos used their toes almost as much as their fingers, and showed great dexterity in picking up things, or in spinning twine, when their toes did quite as much work as their fingers.
The colour of the iris of the Bororo eye was brown, with considerable discoloration around its outer periphery, and especially in the upper part, where it was covered by the lid. The eyes were generally kept half closed.
The anatomical detail of the body was perfectly balanced. The arms were powerful, but with fine, well-formed wrists—exquisitely chiselled, as were all the attachments of their limbs. They had quite graceful hands, long-fingered—in more ways than one—and wonderfully well-shaped, elongated, convex-faced nails, which would arouse the envy of many a lady of Western countries. The webbing between the fingers was infinitesimal, as with most Malay races. Great refinement of race was also to be noticed in the shape of their legs—marvellously modelled, without an ounce of extra flesh, and with small ankles.
