Santa Maria material examined. Maximum height 36.0 mm, width 18.1 mm. One specimen from LNEG collection (unnumbered), exact locality unknown, Santa Maria Island, Azores, Lower Pliocene.

Discussion. An incomplete internal mould comprising the last whorl and siphonal canal, identified as Angustifusus longiroster ( Brocchi, 1814) in the LNEG collection, most likely represents the species which is characterised by its very long and straight siphonal canal. The character of this very long and slender narrowly open siphonal canal and reduced axial and spiral sculpture in adult specimens are characters of the genus Angustifusus Vermeij & Snyder, 2018 . Vermeij & Snyder (2018: 72) suggested that the unusual species Fusinus clavilithoides Landau, Harzhauser, B ̧y̧kmeriç & Breitenberger, 2016 from the middle Miocene eastern Mediterranean Karaman Basin of Turkey, might be placed in this genus. However, the character of the siphonal fasciole is quite different from other members in this group. For further discussion on this species, see below under Fusinus sp.

Distribution. Upper Miocene: central Proto-Mediterranean, Italy ( Montanaro 1935). Lower Pliocene: Atlantic, Santa Maria Island, Azores (this paper), central Mediterranean, Italy ( Pelosio 1966; Cavallo & Repetto 1992; Chirli 2000; Tabanelli 2014; Brunetti & Cresti 2018). Upper Pliocene: North Sea Basin, Belgium (Marquet 1997, 1998); western Mediterranean, Estepona Basin, Spain (NHWN collection), South France ( Chirli & Richard 2008); central Mediterranean, Italy ( Sacco 1904; Ruggieri et al. 1959; Malatesta 1974; Caprotti 1976). Lower Pleistocene: central Mediterranean, Italy ( Cerulli-Irelli 1911; Malatesta 1960); eastern Mediterranean, Rhodes Island ( Chirli & Linse 2011). Upper Pleistocene: central Mediterranean, Italy ( Tabanelli 2014).
