Location: Shores of Blue Mud Bay north to the Koolatong River and inland to an important source of implement stone at Ngilipidji. Their name is based on the local form of the demonstration pronoun 'this.' This tribe appears to be the northernmost coastal tribe in eastern Arnhem Land to possess the normal Australian form of tribal structure. There are two clanlike groups that intermarry, the Dalwangu (Jiritja moiety) and the Djawark (Dua moiety). There is also marriage with the people to the north who have a different type of group arrangement. There is a similarity in their nomenclature in that they use forms of the demonstrative pronoun in identifying themselves in the same manner as the northerners. My placing of this tribe on the 1940 map was in error.
