Calliostoma perfragile G.B. Sowerby (III), 1903
Calliostoma perfragile G.B. Sowerby (III), 1903: 222, pl. 5, fig. 3. E.A. Smith, 1906: 54. Barnard, 1963a: 258, figs 14g (radula), 15e. Kensley, 1973: 36, fig. 63. Springsteen, 1981: 4, fig. 8. Lussi, 2014: 17, un-numbered figure. Type loc.: Vasco de Gama Pk. bearing S 75° E; distant 13½ miles; depth, 166 fathoms [304 m]; ‘figured type’ in SAMC (A5275) (holotype according to Giles & Gosliner (1983), another syntype in NHM (NHMUK 1903.7.27.64), Salvador pers. comm. (iii/2015).
Calliostoma capense Thiele, 1925: 20 [54], pl. 13, fig. 33. Type loc.: Valdivia St’n 113, SW of Cape Point (34°33.3ʹS: 18°21.2ʹE), 318 m; holotype in ZMB.
Distribution. Agulhas Bank, southern Transkei to Cape Point, perhaps also KwaZulu-Natal; 100–350 m (living 100–300 m).
Notes. The use of the term ‘holotype’ for the SAMC syntype by Giles & Gosliner (1983) does not fit the criteria for designation of lectotype either by selection or inadvertent designation (ICZN, Art. 74.5), nor by inference of holotype (ICZN, Art. 74.6) because the original description clearly stated that there were two specimens.
