Mariene mollusken uit het oostelijk deel van de Middellandse Zee 11. Een eerste vondst van Cerithium columna Sowerby, 1834

The find of a single, empty shell of Cerithium columna is reported from the beach of Caesarea, Israel. The shell shows a hole made by a naticid species in the penultimate whorl. Nine cerithiid species of Eritrean origin have now been recorded from the Mediterranean beaches of Israel. Only Cerithium scabridum and Rhinoclavis kochi may be considered as well established Lessepsian migrants, which have even replaced a number of native Mediterranean species. Cerithium egenum seems to have established itself also in the Eastern Mediterranean.
