The brachiopod super-family Productacea is represented in the Permian faunas of Western Australia by at least 34 species, many of which occur in at least two of the three major areas of marine Permian sediments. These areas, from north to south, are the Canning Basin, the Carnarvon Basin, and the Irwin Basin, together an area of approximately 150,000 square miles. The Permian succession in each of these basins begins with glacial sediments and is followed by a variety of sediments, marine and non-marine, with a total thickness of over 12,000 feet in the Carnarvon Basin. The marine formations are often richly fossiliferous, containing abundant remains of the Productacea. Study of the Western Australian material has enabled discussion of certain features, the function and taxonomic value of which are imperfectly understood. Important amongst these are the shell structure, attachment scar, musculature, trail, and the living position of the shell. The collection studied consisted of well over three thousand specimens, most of them well preserved. There are seven species of Aulosteges; the genus Dictyoclostus is represented by three species; the genus Krotovia (emended) by four species; the genus Linoproductus by three species; the genus Marginifera by one species; the genus Waagenoconcha by one species. Taeniothaerus, an Indo-Pacific genus, is represented by seven species, one of doubtful affinities. In the subfamily Strophalosiinae, Etheridgina, is represented by one species; Strophalosia by three species, one of them very doubtfully represented, and its subgenus Heteralosia by five species, one of these being doubtfully represented.
