Protoschmidtia foraminosa f. mamillata subf. latissima Czerniavsky, 1880 Protoschmidtia foraminosa f. mamillata subf. latissima Czerniavsky, 1880: 100 Described by Czerniavsky from Yalta Bay, Crimea, approximate coordinates 44.48°N 34.17°E (no material has been identified in ZIN-RAS). The combination is invalid on account of having four names (ICZN art. 45.5). As indicated above I propose to assign the specimen to the species Haliclona foraminosa (Czerniavsky, 1880).
