The Goothanto and Wollungurma have Ranya, Rara, Loora, and Awunga (8); allied to these perhaps are the Jury, Ararey, Barry, and Mungilly of the Koogobathy; the Ahjeerena, Arrenynung, Perrynung, and Mahngal of the Koonjan are clearly variants of the latter set. East of the Koogobathy lie the Warkeman with Koopungie, Kellungie, Chukungie, and Karpungie (6), with an allied tribe on the Tully River with classes, Kurongon, Kurkulla, Chikun, Karavangie, the two latter obviously corresponding to Warkeman classes, the second to Koorgilla.
The Miappe, Mycoolon, Kalkadoon, and Workoboongo have Youingo, Maringo, Badingo, and Jimmilingo (9), with alternatives Kapoodingo, Kungilingo, and Toonbeungo.
The Yoolanlanya and others have Deringara, Gubilla, Koomara, and Belthara, possibly a defective list, for Mr Mathews adds to these for the Ullayilinya Lookwara and Ungella (probably a defective set) in another communication. Two of these are obviously identical with the Arunta Koomara and Bulthara, with which are associated Purula and Panungka (13), while Ungilla and Gubilla are taken from the eight-class system to which we may probably assign the tribe. North-west of the Arunta, outside the eight-class area, the class names are almost identical with, though they differ widely in form from the Arunta names. They are Burong, Ballieri, Baniker, and Caiemurra (13). The form Boorgarloo is given as a variant. Mrs Bates has found a system (14) in S. W. Australia.
On the western shores of the Gulf of Carpentaria we find the Mara with Purdal, Murungun, Mumbali, and Kuial (10); and the Anula with Awukaria, Roumburia, Urtalia, and Wialia (11).
The only two remaining four-class systems of which the names are known are on the Annan River with Wandi, Walar, Jorro, and Kutchal (7)—the Ngarranga of Yorke Peninsula, with Kari, Wani, Wilthi, and Wilthuthu.
Attention has been called in the course of the above exposition to various cases in which the class names found among one group of tribes are in part if not entirely identical with those found among their neighbours. A close examination discloses other possible though hardly probable points of contact besides those already enumerated. The variant form Banjoora in 3 seems to be the same as the Banjoor of the Kangulu, which again has Koorpal in common with 4, and also Kearra, if we may equate the latter with Kuialla. This again is perhaps the Kuial of the Mara tribe (9).
The Marroong of 2 seems to be the Maringo of 9, and we may perhaps also equate the Kurbo of this group with the Kurpal of 4. Irroong resembles the roanga of the Karandee which is probably the Arawongo of the Goothanto.
In 5 Wongo suggests the Youingo of 9; it reappears in the Halifax Bay list, as also does Koorgilla in one of the variants. Again Kubi (1) corresponds to Koobaroo (5), and Kumbo (Wombee) to Bunburi (Unburi), but we can hardly regard them as the same words. Koodalla and Koorpal (4) may be the same as Kellungie and Koopungie (6); the other pair shows no resemblance.
Possibly the Wiradjeri Wombee is the Kombinegherry Wombo; it is at any rate significant that the name is found in the portion of the tribe nearest the Kombinegherry.
We have seen that the Arunta and their north-western neighbours have a four-class system, the component names of which are found with little variation over a range of nearly 25° of longitude. In the forms Kiemarra, Palyeri, Burong, and Baniker, the class names in vogue among the southern Arunta meet us again near the North-West Cape, thus covering a larger area than even the widespread Koorgila-Bunburi class names of Queensland, and forming a striking contrast to the narrow limits of the majority of the four-class system. This peculiarity is reproduced in the compact area of the central eight-class tribes, north and north-east of the Koomara four-class area, though with much greater variations in the names. Bulthara however in the form Palyeri is found in more or less disguised shapes in the whole of the eighteen tribes, whose class names are shown in Table Ia; Koomara is found in shapes which are on the whole harder to recognise, and Panunga and Purula in two or three cases, either replaced by another word or so changed as to be unrecognisable. Of the supplementary names belonging to the eight-class Arunta, Uknaria, Ungalla, Appungerta, Umbitchana, Ungalla is found in the whole of the tribes under consideration, and Appungerta undergoes on the whole but little change; Uknaria is practically not found outside the Arunta area, and Umbitchana is in six cases replaced by Yacomary, which seems to be a form of Koomara (to this point we recur later).
