The Kámilarói tribes in South Australia are divided into four clans, in which brothers and sisters are respectively Ipai and Ipātha, Kŭbi and Kubĭtha, Mŭri and Mātha, Kumbu and Būtha. Ipai may only marry Kubĭtha; Kŭbi, Ipātha; Kumbu, Mātha; and Mŭri, Būtha. In a certain sense, we are told, every Ipai is regarded as married, not by any individual contract, but by organic law, to every Kubĭtha; every Kŭbi to every Ipātha, and so on. If, for instance, a Kŭbi “meet a stranger Ipātha, they address each other as _spouse_. A Kŭbi thus meeting an Ipātha, though she were of another tribe, would treat her as his wife, and his right to do so would be recognised by her tribe.”[265] This institution, according to which the men of one division, have as wives the women of another division, the Rev. L. Fison calls “group marriage.” He contends that, among the South Australians, it has given way in later times, in some measure, to individual marriage. But theoretically, as he says, marriage is still communal: “it is based upon the marriage of all the males in one division of a tribe to all the females of the same generation in another division.” To this may be added a statement of the Rev. C. W. Schürmann with reference to the Port Lincoln aborigines. “As for near relatives, such as brothers,” he remarks, “it may almost be said that they have their wives in common.... A peculiar nomenclature has arisen from these singular connections; a woman honours the brothers of the man to whom she is married with the indiscriminate name of husbands; but the men make a distinction, calling their own individual spouses yungaras, and those to whom they have a secondary claim, by right of brotherhood, kartetis.”[266] Speaking of the Fuegians, Admiral Fitzroy says, “We had some reason to think there were parties who lived in a promiscuous manner—a few women being with many men.”[267] The Lubus of Sumatra, the Olo Ot, together with a few other tribes of Borneo, the Poggi Islanders, the Orang Sakai of Malacca, and the mountaineers of Peling, east of Celebes, are by Professor Wilken stated to be entirely without marriage.[268] The same is said by Professor Bastian to be the case with the Keriahs, Kurumbas, Chittagong tribes, Guaycurûs, Kutchin Indians, and Arawaks.[269] He states, too, that the Jolah on the island of St. Mary, according to Hewett, possess their women in common,[270] and that, according to Magalhães, the like is true of the Cahyapos in Matto Grosso.[271] We read in Dapper’s old book on Africa, that certain negro tribes had neither law, nor religion, nor any proper names, and possessed their wives in common.[272] These are all the statements known to me of peoples alleged to be without marriage.
