"The Ivory-white Galfridus." White, dull; growth lines irregular, lamellar, making a frill immediately below the suture, corresponding with a small round sinus there; spirals fine, crowded; spire less than half the height of the mouth; protoconch two-whorled, with twelve spirals; adults whorls about three, rounded; the false umbilicus, which is absent from young shells, is only a separation of the lower part of the inner lip from the sinistral twist of the extremity of the columella. Height 14, diam. 7 mm. Beach, Port Willunga, Fowler Bay, Venus Bay, St. Francis Island, and dredged Backstairs Passage, 17 fathoms. Rather rare. (Type locality—Tamar Heads, Tasmania). Occurs also in Tasmania and Victoria. G. eburneus is smoother and thinner than speciosus, and the thick varices of the latter are reduced in eburneus to mere lines of growth. G. eburneus is the Flindersian shell.
