MATERIAL AND DIMENSIONS. — Maximum height 2.1 mm, width 1.1 mm. — RGM.1364993 (10), leg. ACJ ; RGM.1365198 (1), leg. ACJ ; RGM.1365202 (200+), leg. AWJ .

SPECIES CHARACTERISATION. — Smooth, solid, fusiform shell with regularly conical spire. Five flat teleoconch whorls separated by shallow suture. High base; pyriform aperture.

DISTRIBUTION. — Lower Pliocene: NSB, Coralline Crag, England ( Wood 1848), Iceland ( Símonarson et al. 2021). — Upper Pliocene: NSB, Red Crag, England (Harmer 1925; Norton 1967). — Lower Pleistocene: Atlantic, England (Harmer 1925), Selsoif,NW France (this paper). — Upper Pleistocene to Holocene: NSB, England (Harmer 1925), Netherlands (Van Regteren Altena et al. 1954; Hoeksema & Raad 2015). Today, this species occurs in the eastern Atlantic from northern Norway ( Bank & Neubert 2020), along the coast of Europe to Senegal ( Fretter & Graham 1978), it enters the Mediterranean and extends into the Aegean Sea ( Öztürk et al. 2014) and Baltic Sea ( Kedra 2010).
