Remarks

The names Cerithium pulchellum C.B. Adams, 1850 or Triphora pulchella were used by many authors (e.g., Abbott 1974; Rios 2009). It is a junior homonym of Cerithium pulchellum Sowerby, 1832 , a senior synonym of the cerithiopsid Horologica pupa (Dall & Simpson, 1901) (De Jong & Coomans 1988; Rolán & Espinosa 1992) and its type material is lost (Clench & Turner 1950). Thus, C. pulchellum C.B. Adams, 1850 is not a synonym of S. intermedia , as suggested by Rolán & Fernández-Garcés (2007, 2008), but T. pulchella auct. non C.B. Adams, 1850 is indeed a synonym.

Another problematic name is Triphoris pulchellus A. Adams, 1854 , which Albano et al. (2019: 171) wrongly indicated was regarded as a synonym of Similiphora intermedia by Rolán & Fernández-Garcés (2008); actually, Rolán & Fernández-Garcés (2008) referred to the species of C.B. Adams (1850), not A. Adams (1854). Because the single type of Triphoris pulchellus A. Adams, 1854 has a broken apex (without protoconch, preventing a precise identification) and the type locality is unknown, it must be regarded as a nomen dubium (but not regarded as homonym of the cerithiopsid Cerithium pulchellum C.B. Adams, 1850 ). If this is indeed a Caribbean shell, the most similar species is Triphora atlantica Smith, 1890 , although apparently without the spiral microsculpture observed in T. pulchellus A. Adams, 1854 (Albano et al. 2019: fig. 7h).
