Arenaceous Foraminifera dominate the foraminiferal assemblages in the Lower Cretaceous sediments of Australia. The majority of species described in this Bulletin come from surface and subsurface sections within the Queensland part of the Great Artesian Basin, and their occurrences, for the most part, are referred to stratigraphical formations in the Basin. In addition, species have been described from samples from northern New South Wales and parts of South Australia and Western Australia. Well-known Lower Cretaceous megafossils give a clue to the stratigraphical position of many of the samples from which the foraminifera have been obtained. Seventy-five species of arenaceous foraminifera are discussed; they belong to twenty-six genera. Twenty-three new species are described, eight of which belong to the genus Ammobaculites. Many of the arenaceous forms show a close relationship with species described from the Lower Cretaceous deposits of northern Alaska, western Canada, and parts of the United States of America.
