Fossil: Pleistocene, Port Elizabeth (Johnson, 1904). Port Elizabeth, Algoa Bay (von Martens, Euthyme, Sowerby). Natal, 3 juv., dead (S. Afr. Mus. coll. E. L. Layard). False Bay (S. Afr. Mus.). Off Cove Rock (East London), 34 fathoms, 1 dead but with periostracum, coll. (Tomlin). Algoa Bay, 21-50 fathoms, 1 living, 5 dead; off Cape St. Blaize, 42 fathoms, 1 dead (S. Afr. Mus. coll.). Delagoa Bay, living (). Distribution. Arabian Sea, W. Australia, Japan. Also Pliocene of Java and Mekran (Vredenburg). Remarks. Fourteen specimens, 24-122 mm. long, examined. Growth sequence: 2J postnatal whorls length 24-27 mm., 2J whorls 35 mm., 3J whorls 76 mm., 3J whorls 76-78 mm., 3f~4 whorls 87-94 mm. The width varies from 80% to 85% of the length; in the 4 largest examples, 87, 90, 94 and 122 mm., the width is respectively 92%, 88%, 87% and 82%. In one specimen 26 mm. long the 5th lira is obscured by the suture of succeeding whorl; sometimes the suture runs on the 5th lira but usually this lira is clearly visible in the channelled Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
