The areas covered by the different class and phratry names are not co-extensive, that is to say a class is associated with more than one phratry and vice versâ. The Undekerebina[98] and Yelyuyendi[99] have phratries (No. 29) which are usually associated with classes but in their case none have been noted. On the other hand it is not uncommon to find classes without the corresponding phratry names; this is the case in the eight class area, among the tribes of N. S. Wales, S. Queensland, etc.; but no special significance attaches to it unless we are certain that it is not the negligence of the observer nor the disuse of the names which has produced this state of things. On the other hand the relation of phratry and class areas is of the highest importance, as is shown in Chapter V. The following table shows the anomalies:
| Tribe | Phratry | Class |
| Wiradjeri | 21 | I |
| Euahlayi | 22 | I |
| Ngeumba, Wonghi | 23, or 24 | I |
| Murawari | 25 | I |
| Kiabara, etc. | 20 | III |
| Dippil | 26 | III |
| Kuinmurbura, Kongulu | 27 | IV |
| Yuipera, Badieri, Yambeena, etc. | 27 | V |
| Kogai, Wakelbura, etc. | 28 | V |

CHAPTER V.
PHRATRY NAMES.
The Phratriac Areas. Borrowing of Names. Their Meanings. Antiquity of Phratry Names. Eaglehawk Myths. Racial Conflicts. Intercommunication. Tribal Migrations.
It has been shown in Chapter III that from the point of view of kinship organisations Australia falls into three main areas—occupied by the classless two-phratry, the four-class and the eight-class organisations. The total number of phratry names, thirty-three pairs in all, does not of course fall solely to the count of the two-phratry tribes, but is divided between the three kinds of organisation, the two-phratry having twelve pairs with one anomalous area, the four-class sixteen, and the eight-class five such sets. As regards the relative size of the areas thus organised, the largest seems to be that occupied by the Matteri-Kiraru system, though the Muquara-Kilpara (5) probably runs it close, especially if we take into account the names of like meaning (1-4) in the East Victorian area. The remainder of the two-phratry systems do not range over a wide extent of country, so far as is known; but 10, 11, and 33 are of unknown extent.
