Within the genera of fossil Echinodermata three junior homonyms are found and the following replacement names are proposed: Edrioblastocystis nom. nov. pro Blastocystis Jaekel, 1918 nec Aléxéieff, 1911 and consequently Edrioblastocystidae nom. nov. to replace Blastocystidae Jaekel, 1918; Euzonohymenosoma nom. nov. = Hymenosoma Lehmann, 1957 nec Desmarest, 1823; Pennsylvanicycloscapus nom. nov. = Cycloscapus Moore and Jeffords, 1968 nec Erdös and Novicky in Erdös, 1951. Accordingly, also three new combinations (comb. nov.) are established.
