The bibliography concerning the Mediterranean Sipuncula is reviewed, particularly that from the eastern Mediterranean. Additional data are provided from macrobenthic samples collected between 1974 and 1997 in the Hellenic waters. A total of 17 species are recorded, five of which ( Sipunculus norvegicus , Golfingia elongata , Nephasoma lilljeborgi , Thysanocardia catharinae and Aspidosiphon ( Akrikos ) mexicanus ) are reported for the first time in Hellenic waters. Three more species ( Onchnesoma squamatum squamatum , Aspidosiphon ( Aspidosiphon ) elegans , Apionsoma ( Apionsoma ) trichocephalus ) which are found exclusively in the extreme eastern basin (Israel, Egypt) raises the number of eastern Mediterranean Sipuncula species to twenty.
