. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. CONTRIBUTIONS TO THE KNOWLEDGE OF MARINE MOLLUSGA 245 Radula with c. 40 rows, central plate with cusp serrate on both margins, lateral plates with cusp serrated on outer margin, laterals passing gradually into the slender hamate marginals, which are also serrated on outer margin. Port Elizabeth (Sowerby); Durban and Tongaat (S. Afr. Mus.). Natal, presumably living (Krauss). Living: Umgazana (Port St. Johns) (); DelagoaBay (). Remarks. The Tongaat specimens were identified many years ago by J. H. Ponsonby. As no material of other species is available, this identification is here accepted. The figures in the Thesaurus of sulcifera, articulata, orbiculata, etc. are useless for specific determination. The Durban and DeJagoa Bay shells agree with those from Fig. 12. a, Stomatella sp. (Sedgefield), two views, with apex further enlarged. + and o indicate corresponding lirae on the two figures, b, S. articulata A. Adams, radula plates. It is unlikely that any species of Stomatella lives on the shores of Algoa Bay, and the reported occurrences of shells from that area (Sowerby, 1892, and Tomlin, 1923, p. 50) were probably due to human agency. Turton did not obtain any at Port Alfred. Schwarz (1910, p. 115) recorded both articulata and sulcifera from Pleisto- cene deposits at Port Elizabeth. f Stomatella sp. Fig. 12 a Specimens 6x8 mm., protoconch nucleus plus 3! whorls; 7x10 mm. with 4^ whorls; 18 X 23 mm. with 5! whorls. Profile of 2nd and 3rd whorls tabulately angular, of 4th and 5th whorls convex, sloping. Sutures not indented;.
