Location: Coastal plain north of the Fortescue River; north to visited islands of the Dampier Archipelago on log rafts; inland only to foot of ranges. These are perhaps the people described by King, (1827:i:38) as tide riding on logs near Lewis Island. Brown (1913) gave them a tribal area of 3,500 square miles (9,100 sq. km.) which seems to be an overestimation. The name has been checked in the field as above.
