At least eight forms of the brachiopod genus Camarotoechia occur in the Carnarvon, Fitzroy, and Bonaparte Gulf Basins of Western Australia, four in Upper Devonian rocks and four in Carboniferous rocks. One of the Carboniferous species ranges into the Northern Territory. One species, C. lucida, is already described, three species are indeterminate, and four, C. amnica, C. puteana, C. septima, and C.eganensis, are described as new. Each species has been found only in one basin, and the genus cannot therefore be used in correlation between basins; but within each basin, species of Camarotoechia are abundant, and prove to be valuable stratigraphical indices, particularly in distinguishing Upper Devonian from Lower Carboniferous rocks. Five brachiopod species from the Gneudna Formation of the Carnarvon Basin are described: Productella oecidua sp. nov., Camarotoeehia puteana sp. nov., Spinatrypa aspera prideri (Coleman) 1951, cf. Ladjia saltica Veevers 1959, and an indeterminate smooth spiriferid. Corals (HilI, 1954) and brachiopods (Glenister, 1956) already described from the Gneudna Formation are listed, and some corrections noted. The brachiopods described below are used in determining the age of the Gneudna Formation as Frasnian, the lower half probably middle Frasnian, the upper probably upper Frasnian.
