Abstract

Species belonging to the superfamily Orthotetacea Williams form an important part of the Permian marine faunas of Western Australia. Four genera-Streptorhynchus King, Kiangsiella Chao, Derbyia Waagen,and PermoTthotetes gen. nov.-are represented. Twenty-one species are described and at least two others are indicated by incomplete collections. Many species appear to be restricted in range and are useful in stratigraphical correlation. The group of strophomenoid brachiopods now known as the superfamily Orthotetacea Williams 1953 has been for many years of interest to brachiopod students. Representative species are widely distributed throughout the world. The group attains its acme in the Upper Palaeozoic, particularly in Upper Carboniferous and Permian time. Six species only have hitherto been recorded in the Permian of Australia. One species has been described from the Permian of Eastern Australia-Streptorhynchus pelicanensis Fletcher, originally described by Etheridge in 1892 as Orthotetes senilis, from Queensland. Streptorhynchus perfidiabadensis (Etheridge) occurs at Treachery Bay, Northern Territory. Two species of Streptorhynchus and a Derbyia-like form were described from the Permian of Western Australia by Hosking (1932). In recent years extensive field work by geologists of the Bureau of Mineral Resources and of the University of Western Australia has added greatly to knowledge of the Western Australian Palaeozoic rocks and has augmented collections considerably. The Orthotetacea are now seen to be abundantly represented in Western Australia and are of considerable stratigraphical value. Four genera with at least 23 species can be distinguished in the Permian. The genus Schuchertella is known in the Devonian of the Fitzroy Basin and in the Lower Carboniferous Laurel Beds of the Fitzroy Basin. Schellwienella has lately been recognized in the Lower Carboniferous Septimus Limestone of the Bonaparte Gulf Basin and in the Lower Carboniferous Moogooree Limestone of the Carnarvon Basin. Schellwienella and an unidentified genus are present in the Carboniferous Weaber Group of the Bonaparte Gulf Basin of the Northern Territory.
