160 R. H. MATHEWS. 
In course of time a further segregation of the Kamilaroi 
ancestors took place. The Dilbi group was divided into two 
sections, called Murri and Kubbi, and the Kupathin group into 
two, called Ippai and Kumbo. There appears, however, to be no 
evidence as to whether this subdivision took place simultaneously 
with the separation of the community into two groups, or ata 
later period. The divisions into groups and sections are matters 
which have happened so far back in the past, that the natives of 
the present day have no traditions respecting them. The names 
assigned to the women belonging to these sections are different to 
those borne by the men: the sisters of Murri and Kubbi are 
Matha and Kubbitha respectively, and the sisters of Ippai and 
Kumbo are named Ippatha and Butha. These names will be 
understood more clearly by referring to Table A. This bisection 
of the original groups did not apply to the totems, who continued 
to be designated as Dilbi and Kupathin as before, which seems to 
favour the suggestion stated farther on, that the sectional divisions 
may have been inaugurated for the purpose of a distinctive’ nomen- 
clature. 
Under this second bisection of the community a Dilbi man still 
marries a Kupathin woman, but it becomes necessary that she 
shall belong to one of the sections, Ippai or Kumbo ; and the name 
of this section is determined by the section of the Dilbi group to 
which he himself belongs. If he belong to the Kubbi section he 
must marry an Ippatha, but if he is a Murri his wife must be @ 
Butha. Similarly, if a Kupathin man wishes to marry, and he is 
an Ippai, he selects a Dilbi woman of the Kubbi section, but if 
he is a Kumbo, he must marry a Matha. 
The descent of the children under this new method of division 
is somewhat modified. If a Kupathin man of the section Kumbo 
marry a Matha eaglehawk, the children will be Dilbi eaglehawk 
the same as before, but they will not be Murris and Mathas like 
their mother. They will take the name of the other section in 
the Dilbi division, and be called Kubbis and Kubbithas. In 
examining the rules of marriage and descent as stated in this and —
