Sowerby (III), 1903 Calliostoma perfragile G.B. Sowerby (III), 1903 : 222 , pl. 5 , fig. 3 . E.A. Smith, 1906 : 54 . Barnard, 1963 a : 258 , figs 14g ( radula ), 15 e. 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 13 ½ miles; depth, 166 fathoms [ 304 m ]; ‘figured type’ in SAMC (A 5275 ) ( 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.
