Shell oval, longer than high; bluntly pointed anterior side; subequal auricles; smooth outer surface. Prodissoconch: shell type ST-2D; length about 120 µm; roundish D-shaped outline; low convex profile; P- 1 surface pitted; rim-like P-2 barely separated from P-1; transition to the nepioconch well marked.   Occurrence. Box-corer samples BC66 (1 specimen), BC71 (1), BC72 (6); core BC72 (1). Maximum height: 4 mm.   Distribution and habitat. The species is reported to have a cosmopolitan distribution, usually on sand (often coralline sand) and fine gravel with a variable amount of mud, from infralittoral to bathyal depths ( Nordsieck 1969; Poppe & Goto1993; Oliver et al.2016).  Fossil record.Miocene of Poland, France and Italy; Pliocene of the Mediterranean, Belgium and Great Britain; Pleistocene of Denmark, Italy and Great Britain ( Monterosato 1872; Sacco 1897; Brambilla 1976; Barrier et al.1987; Monegatti & Raffi 2001; Petersen 2004). 1324948122 Goto 28 29 1 Goto
