The molluscan fauna of the Borgloon Formation (Early Rupelian, Early Oligocene) from Belgium (provinces of Limburg and Vlaams Brabant) is described and its systematiscs and nomenclature are revised. This fauna consists of 90 taxa (the presence of two species is doubtful), viz. 1 Amphineuran, 25 Bivalves and 64 Gastropods. 32 taxa have not been mentioned before from the Borgloon Formation; of these, 14 had already been described from other Formations, 6 are new, 12 are too incompletely preserved or lack well described comparative material (this last category contains mainly terrestrial species) to assess their taxonomy. The faunal composition of the different Members of the Formation is compared. The fauna of the Henis Clay shows the lowest diversity, the one of the Alden Biesen Member the highest. All faunae are of brackish water origin. The Alden Biesen Member furthermore contains a number of terrestrial as well as marine species, which notably enrich the species number, the sands of the Boutersem Member have less mixture of terrestrial and marine material; the Vertebrates and Chara Marls of this Member have mainly a freshwater fauna, with rarer brackish and marine elements. Different freshwater species occur in the Boutersem and Alden Biesen Members, which shows a different apport of material, supposed to be of inhabitants of streaming water in the Alden Biesen Member and of rather stagnant water in the Boutersem Member. Species occurring in the Borgloon Formation have been found all around Europe, but the largest number of species is in common with the Oligocene from the Paris and Mainz basins. Only a very limited number of the taxa occurring in the Borgloon Formation is in common with the older Grimmertingen Member and few evolutionary lines continue during the later parts oft he Middle Oligocene. 100 pp., 14 figs, 5 tabs, 22 pls, br. 4.…

In this paper, the systematics of the Gastropoda of the Grimmertingen Sand Member, the earliest part of the Oligocene in Belgium, is revised. The fauna is calculated at 182 species, compared with 147 named in the work of Glibert & de Heinzelin (1954). Three species have to be removed from their list for various reasons. Nine species are new to science, but only three could be named: Parvisipho oligocaenica sp. nov., Raphitoma grimmertingenensis sp. nov. and Raphitoma neerrepenensis sp. nov. The available material of the six others was not well enough preserved for unequivocal identification: Obtusella sp. nov., Acamptogenotia sp. nov., Mangelia sp. nov., Bonellitia sp. nov., ? Tuba sp. nov. and Turbonilla sp. nov. or Acirsa sp. nov. A new name is given to one taxon: Terebellum koeneni nom. nov. The fauna of the localities in the province of Limburg is compared with those of the younger Belgian Oligocene fauna and of the European Eocene and Oligocene fauna in general. It shows little similarity with any of these faunae, except with the contemporaneous Dutch and German ones. A strong impoverishment of the fauna after these "earliest" Oligocene faunae is apparent everywhere in the North Sea Basin. The number of species in common with the Late Eocene is about the same as that with the later Oligocene. Moreover, the number of genera surviving from the Eocene into the Oligocene outnumbers the appearance of typical Oligocene genera in the Grimmertingen Sand Member, e.g. Haustator crenulatus, the most common gastropod, already occurred in the Eocene Wemmel Sand Member. The number of species within the surviving genera is more numerous than the number of species within the newly appearing Oligocene genera. This is a clear indication of the more Eocene than Oligocene character of the Grimmertingen Sand Member. Only one pteropod was found, due to the decalcification of the Grimmertingen Sand member, which did not favour the preservation of these fragile shells. 157 pp., 1 fig., 4 tabs, 24 plates, br. 4.…
