Another important feature in Australian totemism strengthens our position. The idea of the animal kinship must be an ancient one in the race, because the family surname, Emu, Bandicoot, or what not, and the crest, kobong, or protecting and kindred animal, are inherited through the mother's side in the majority of stocks. This custom, therefore, belongs to that early period of human society in which the woman is the permanent and recognised factor in the family while male parentage is uncertain.(1) One other feature of Australian totemism must be mentioned before we leave the subject. There is some evidence that in certain tribes the wingong or totem of each man is indicated by a tattooed representation of it upon his flesh. The natives are very licentious, but men would shrink from an amour with a woman who neither belonged to their own district nor spoke their language, but who, in spite of that, was of their totem. To avoid mistakes, it seems that some tribes mark the totem on the flesh with incised lines.(2) The natives frequently design figures of some kind on the trees growing near the graves of deceased warriors. Some observers have fancied that in these designs they recognised the totem of the dead men; but on this subject evidence is by no means clear. We shall see that this primitive sort of heraldry, this carving or painting of hereditary blazons, is common among the Red Men of America.(3) (1) Cf.

In Central Australia there is a marked difference in the form of Totemism.
