Semicassis aff. reticulata (Bellardi & Michelotti, 1840) (Bon.) Fig. 6L Cassis reticulata Bon. Bellardi & Michelotti, 1840: 53 (145) [Bon. refers to an unpublished museum catalog]. Semicassis reticulata – Sacco 1904: pl. 20 figs 18–19. — Ferrero Mortara et al. 1984: pl. 1 figs 9–10. Material examined ITALY – Emilia-Romagna • 1 spec.; Castiglion dei Pepoli; MGGC 22310 (H = 48.6, W = 42.0 mm). Remarks This specimen is here assigned to Semicassis based on the similarities with the species outlined below. It should be noted, though, that certain deep-sea buccinids produce very similar globular shells with fine spiral sculpture. Examples include a Latisipho sp. that was recently reported from hydrothermal vent in the Bering Sea (Nekhaev et al. 2022), and Buccinum cascadiense Clarke, 2022, from the Northeast Pacific (Clark 2022). The Middle Miocene Semicassis reticulata (Bellardi & Michelotti, 1840) as illustrated in Sacco (1904: pl. 20 figs 18–19) and Ferrero Mortara et al. (1984: pl. 1 figs 9–10) has a less globular last whorl and lacks the distinct shoulder. All species of Semicassis from the Miocene of the Paratethys (Landau et al. 2009: pl. 4) have a lower spire with less convex whorls than the specimen from Castiglione dei Pepoli. A similar whorl profile as the specimen from Castiglione dei Pepoli has Semicassis miolaevigata Sacco, 1890, but that species typically has less distinct spirals on the whorls’ flank (Sacco 1904: 97, pl. 20 figs 5–10) and Ferrero Mortara et al. (1984: pl. 1 fig. 6). Another species with similar fine spiral sculpture on the entire whorl is the Early Miocene Sconsia ottnangensis (Sacco, 1890). However, the specimens illustrated by Landau et al. (2009: pl. 5 figs 1–2) are somewhat deformed and the similarity in shell shape to the specimen from Castiglione dei Pepoli may be an artifact. Specimens reported as Phalium ( Semicassis ) bituminatum (Martin, 1943) from a presumed mud volcano or seep deposit in the Late Miocene of Waisiu, Buton Island, Indonesia (Beets 1942: 277, pl. ...
