Collected by J. Fryda

• The new taxa described here come from weathered beds of the Early Devonian Koněprusy Limestone (Praha Formation) of Pragian age found by one of us (LF) at the Císařský lom quarry (Fig. 1; Frýda & Ferrová 2011). These weathered beds contain a rather highly diversified gastropod fauna, which is under study. SEM-images of the first several whorls were used for measurement of protoconch size as well as for documentation of shell morphology (Figs 2, 3). Shells of all the newly described species (both figured and unfigured) are deposited in the Czech Geological Survey (Prague) under numbers (UUG JF 907–959). Abbreviations: NMP National Museum, Prague, UUG JF—Czech Geological Survey (Prague).
