Dieri, but it may possibly occur in others of the adjacent tribes. It is based upon the Nadada-noa relationship, which is fully described in the chapter on Relationships.
(3) It may happen, when a boy has been circumcised, that his mother arranges with some other woman, who is Kami-mara to her, and who has an unbetrothed daughter, to make the two children Tippa-malku, there being also the usual promise to exchange a sister of the boy. The girl's mother is then painted in a certain manner, which indicates to all and sundry that she is the Paiara (wife's mother) of that woman's son.
