Location: On the Montgomery Islands, n.n. ['Jawutjap] (this name applies probably only to the main island), including those in the southern part of Collier Bay. In 1931 they were being absorbed among the Worora as an Atpalari moiety clan, but were stated by J. R. B. Love to represent a different physical type of people. Tradition is that the islands were once a large country but a big flood came and drowned it so that now there are only islands.
