A very large area is occupied by tribes with the classes (5) Koorgila, Bunburi, Wunggo, and Obur (and variants).  They include the Yuipera and allied tribes, the Kogai, the Wakelbura and allied tribes, the Yambeena, the Yerunthully, the Woonamurra, the Mittakoodi, the Pitta-Pitta, etc., together with the Purgoma of the Palm Islands and the neighbouring Jouon, whose headquarters are at Cooktown.  In the southern portion of this group a correspondent of Curr’s has reported the classes Nullum, Yoolgo, Bungumbura, and Teilling.  We have class names analogous in form to the third of these names, it is true, but it resembles tribal names so closely as to suggest that the observer in question was really referring to a tribe and not to a class.  If this is so we may perhaps identify Teilling with the Toolginbura.  There seems to be no reason for admitting these four names to a place among the other groups of class names.  In like manner we may dismiss the class names assigned to the Yukkaburra by an inaccurate correspondent of Curr’s, who gives Utheroo, Multheroo, Yungaroo, and Goorgilla.  It seems clear that the first and third of these are really phratry names; possibly the second is a dialectical form for Utheroo.

From Halifax Bay and Hinchinbrook Island are reported the names Korkoro, Korkeen, Wongo, and Wotero (with variants).  Among the Joongoongie of North Queensland we find Langenam, Namegoor, Packewicky, and Pamarung (15); and among the Karandee Curr gives an anomalous and probably defective set, Moorob, Heyanbo, Lenai, Roanga, and Yelet.

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.
