-Th is paper presents the taxonomic classifi cation of gastropod specimens mainly from yet unpublished parts of collections of the Early Jurassic Hierlatz Limestone fauna. Th e discussed species most probably belong to such higher rank taxa that have been formerly thought to become extinct during the Late Triassic crisis and represent groups typical of Palaeozoic to Triassic times. Th e new taxa are: Wortheniopsis rakusi n. sp., Wortheniopsis bakonyensis n. sp., Foveolaria n. gen., Foveolaria bicarinata n. sp., Foveolaria conoidea n. sp., Foveolaria globosa n. sp., Foveolaria suemegensis n. sp., Foveolaria kocsisi n. sp. and Foveolaria sp. (?Pithodeidae), and Cyclostomaria praemonarii n. sp. (Gosseletinidae). With 40 fi gures.

The genus Laevitomaria is reviewed and its palaeobiogeographical history is reconstructed based on the re-examination of its type species

The gastropods from Jurassic neptunian sills of Rocca Busambra (Sicily, Italy) represent an extraordinary assemblage for richness and extremely high degree of novelty, consisting of about 250 species, two thirds new, of twenty superfamilies. Thirty-eight species and 18 genera of Lottioidea, Pleurotomarioidea, Scissurelloidea, Fissurelloidea and Eucycloidea are described. Thirty species and nine genera are new, namely Ramusatomaria nuda gen. et sp. nov., Trapanimaria gattoi gen. et sp. nov.,

Th is paper adds sixteen pleurotomarioidean species to the fauna from the type locality area of the Lower Jurassic Hierlatz Limestone Formation (Hallstatt, Austria). Majority of these species are unknown from former publications; only one species has already been recognised from the Bakony Mts (Hungary). Most of the species belong or are related to the genus Pleurotomaria or Laevitomaria but two new genera are also established besides eleven new species: Neorotomaria n.
