2 and 3 come into the relation of tippa-malku husband and wife by betrothal. The man 1 being the brother of 2 becomes therefore the yimari of 3; 4 being the sister of 3 becomes the yimari of 2. The English
equivalents of yimari are "brother-in-law" and "sister-in-law." To complete the example 3 and i and 2 and 4 become pirrauru husband and wife. The term tippa-malku will be considered later on. The term pirrauru is placed between 2 and 3 to show that were they not tippa-malku they might, being noa-mara, become so.
Diagram II. Kurnai.
As there are no classes in this tribe the sex only of the individual is indicated.
1 and 2 are brothers own or tribal; 3 and 4 are sisters own or tribal; 1 and 2 belong to a certain locality, say x; 3 and 4 to another certain locality, say y. The people of these two localities intermarry, being also exogamous. Their system of relationships, as I have explained in
Native Tribes, p. 170, produces a much larger fraternal group than that of the Dieri, including "own or tribal" brothers and sisters. The extreme instance of a tribal brother is the brogan or comrade of a man, namely one who was initiated at the same time at the Jeraeil.
