Abstract

This Bulletin is a monograph of the trilobites of the subfamily Xystridurinae, and an appraisal of their organization, morphology, ecology, and systematic relations. The taxa here described constitute a substantial addition to the Ordian fauna dominated by the species of Redlichia (Opik, 1970), and t6 the Templetonian fauna; and have provided a supplementary stratigraphic scale within the Cambrian. Since the time of its introduction by F. W. Whitehouse in 1936 the name Xystridura (sp., sp. indet., sp.nov.) has.become a very common palaeontological designation in papers dealing with the Cambrian of the Northern Territory and Queensland, published and unpublished. The material exploited here has been selected from collections belonging to the Bureau of Mineral Resources accumulated between 1948 and 1962; the initial manuscript was destroyed in a fire in 1953 and the collections were greatly depleted. The lost material, however, was subsequently restored, and even substantially increased by the Ordian forms, by the discovery of Galahetes, and by collections from New South Wales. Nevertheless the rehabilitation of the morphogenic history of Xystridura is somewhat incomplete and therefore dogmatic in parts. I collected the larger part of these fossils either in company with the field geologists of this Bureau, or on my own; other contributions were made by geologists of the Bureau. Names of some are mentioned in the text, and of others in my earlier papers; once more I thank them all for the assistance received.
