Type locality Southeast Atlantic Ocean, South Africa, False Bay, St. James (geocoordinates not provided, estimated with gazetteer to be approximately lat. -34.121º, long. 18.457º), intertidal. [details]
Type material Day (1953; 1967) clearly stated that the type specimen was from St. James (Day, 1953: 422), and the type locality "St. James, South Africa" (Day, 1967: 287). However, according to Nygren (2004: 152) and the online catalogue of the NHM, London (Myrianida pulchella), the holotype would be the second specimen studied by Day (1953: 422) (NHM 1961.16.12), from Cape Province, while the specimen from St. James, False Bay (NHM 1953.11.16.9) would be the paratype.  [details]

Etymology The specific epithet pulchella is the feminine of the Latin adjective pulchellus, meaning 'pretty', and refers probably to the colour of the species when alive, described as being uniform salmon pink (Day, 1953) or coral red (Day, 1967).  [details]
