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.  Almost equal in extent to either of the two areas occupied by 27 and 29 is that claimed by the better known Kamilaroi system—­Dilbi-Kupathin, which spreads over a long, comparatively narrow region, but had possibly at one time a wider field from which at the present time only the corresponding class names can be recovered.  Of the remaining thirteen in the two-class region, only 28, one of the Wuthera systems already mentioned, has more than a restricted field of influence.  Of moderate size are the four areas in the eight-class system proper, that of the Mara being small in comparison.

Taking now the native names, we find that, in addition to the Wuthera (Ootaroo) sets already mentioned, the Dieri and Kurnandaburi have Matteri (Mattera) in common, while the latter have in the Baddieri tribe a neighbour which shares the Yungo phratry name with them.  The fact, if correct, that with the Badieri Yungo is associated with Wutheru, and takes the place of the more usual Yungaru, suggests that we may equate the latter with Yungo.  In the eight-class area Uluuru is common to two systems, while a third has Wiliuku, and the fourth Illitchi, all of which seem to be allied, if we may take it that uru, uku, and tchi are suffixes; that they are is borne out by the corresponding names Liaritchi and Liaraku.  Other possible equations are Mukula—­Mukumurra, and Cheepa—­Koocheebinga, but in the latter case, even if koo is a prefix, the distance of the two systems makes any such correspondence improbable.  In Victoria the Malian-Multa equation is indisputable; it is interesting to note that the former is found in N.S.  Wales as the name of the bird, while Multa belongs to Yorke Peninsula.
