father of Kupathin children. Moreover, a Dilbi man selects a 
Dilbi wife, and a Kupathin marries a Kupathin. It has already 
been stated that a Dilbi woman is the mother of Dilbi children, 
and a Kupathin woman produces Kupathin children. Therefore, 
the group Dilbi is self-supporting, because it contains within 
itself the fathers and mothers—the husbands and wives—of its 
members, and the Kupathin group is exactly in the same position. 
A man’s children are not necessarily of the same group and 
section, or of the same totem. If a Kubbi marry two wives, — 
which is permissible, one being, for example, Ippatha brigalow 
and the other Kubbitha pine, his children by the former will be 
Kumbo and Butha brigalow, and by the latter they will be Murri 
and Matha pine. In this example, the sons of one of Kubbi’s 
wives could marry the daughters of the other, because Kumbo can 
marry Matha, and Murri can marry Butha. In order to prevent 
such a close marriage, however, every tribe has strict social 
customs, founded upon public opinion, which will not tolerate the 
union of a man with a woman whose blood relationship is considered 
too near. 
A few remarks on the degrees of kinship existing between the 
members of the different divisions will be interesting. A careful 
study of the foregoing pages will show that the pair of sections, 
Murri and Kubbi, are more nearly related to each other than to 
the members of the other pair, [ppai and Kumbo ; and that the 
latter are more closely connected between themselves than with 
the Murri and Kubbi people. The Murri and Kubbi sections are 
related to each other as “mother’s brother” and “sister's son,” 
according to the generation to which they respectively belong. 
If Murri be the elder, he is ‘mother’s brother” to Kubbi, and the 
latter is his “sister's son” ; but if Kubbi be the elder of the two 
this relationship is reversed. The Ippai and Kumbo sections are 
connected with each other in a precisely analogous manner. The 
importance of this family tie is shown by the fact that if a man be 
- killed by an enemy in any way, it is his “sister's son” who is 
charged with the avenging of his death. _
