A new family, Lingulogavelinellidae, comprising the genera Lingulogavelinella, Orithostella and Bilingulogavelinella, is described from the marine Cretaceous (Albian and Cenomanian) of the Great Artesian Basin in northern New South Wales, Australia, together with a few species of the genera Discorbis, Gavelinella and Pseudolamarckina. They are similar to or identical with species of the above genera recorded from marine Cretaceous sequences in North America (Great Plains), the Mangyshlak Peninsula on the east shore of the Caspian, the northwest Caucasus, the West Siberian Lowland, the Russian Platform, Poland, northwestern Germany, England, France and Sweden. Palaeogeographically, these areas represent the Boreal and Transitional Biogeoprovinces. The occurrence of similar or identical species of boreal aspect in the Great Artesian Basin accords well with the ideas of the present author regarding Mesozoic biogeoprovinces based on foraminifera, namely, that, during the Cretaceous, Australia, New Zealand, and the southern parts of South Africa and South America, and, up to the boundary between the Early and Late Cretaceous, also Madagascar and peninsular India, represented the Austral Biogeoprovince, opposite and equivalent to the Boreal Biogeoprovince of the Northern Hemisphere, and with the Great Artesian Basin as a type area. Fluctuations in general composition of the foraminiferal assemblages are world-wide, so they can not be explained by local events only. The author suggests that they reflect world-wide minor fluctuations in temperature minima and maxima and rapid facies change in the epicontinental seas north and south of the Tethyan and Pacific seaways.
