― Type material not located.

— Valid as Onchidella carpenteri ( Semper 1885; Watson 1925; Hoffmann 1928; Labbé 1934a). Authors thought that the type locality of Onchidium carpenteri was from the Gulf of California: e.g., Hoffmann (1928: 94) cites the type locality as “Straits of De Fuca [Golf von Californien];” even Watson (1925: plate XXXII) made a mistake by placing carpenteri off southern California on his map of all known Onchidella species. In the same one-page paper, Binney (1861) described a new species of Pedipes that was collected from “St Lucas Peninsulae Californiae” which is indeed in Baja California. Fischer and Crosse (1878: 697) confused the type locality of the new Pedipes with that of Onchidella carpenteri . Subsequent authors probably repeated Fischer and Crosse’s mistake without going back to the original description. Nonetheless, the latter is clear about where the five syntypes of carpenteri were collected: “Among the mollusca from the Straits of De Fuca, Mr. Carpenter has detected five specimens of a shelless mollusk, which evidently belong to the genus Onchidium .” The type locality of carpenteri unmistakably is the Straits of Juan de Fuca , between Vancouver Island ( Canada) and the State of Washington (USA).
