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.

In the four-class area are two extensive systems, ranking next after those of South Australia and N.S. Wales; these are Mallera-Wuthera (27) and Pakoota-Wootaro (29); they have a single phratry name in common, which is also found in two other systems; if we add these together, as we may perhaps do on this evidence of a common basis, we have by far the largest phratric system in Australia as the result.
