The concept of the Ordovician gastropod genusMacluritesLe Sueur, 1818, at present includes much variation.MaclurinaUlrichinUlrich and Scofield, 1897, is removed as a subjective synonym ofMacluritesand reestablished as a separate genus. Species ofMacluriteswith spiral grooves on the outer whorl surface and a relatively small umbilicus are transferred toMaclurina. Maclurina manitobensis(Whiteaves, 1890) forms a distinctive part of the Late Ordovician-age “Arctic Ordovician fauna.” An unusually large specimen (25 cm in diameter) from the Bighorn Dolomite (Upper Ordovician), Wyoming, is illustrated; this Wyoming specimen is the volumetrically largest Paleozoic gastropod ever reported.
