Diagnostic characters. High ovate-subrectangular shell; slightly sunken spire; large piriform aperture; broadly arched columellar lip; finely denticulate outer lip margin; densely set spiral rows of shallow oval pits, linked one another in a chain-like pattern. Protoconch: heterostrophic, largely covered by the teleoconch; about 1 visible whorl; diameter about 520 µm (estimated); surface apparently smooth; transition to the teleoconch marked by a simple lip.

Remarks. The similar P. c a t e n a ( Montagu, 1803) differs in having a shorter shell, a non-denticulate outer lip margin and a more evident chain-like sculptural pattern.

Occurrence. Box-corer sample BC72 (3 specimens); core BC21 (1). Maximum height: 3.5 mm.

Distribution and habitat. The species ranges from Iceland and Norway to West Africa, Madeira and the Mediterranean, dwelling on sand from the lower shore to about 1500 m depth and often being prey of flatfishes ( Thompson & Brown 1976; Poppe & Goto 1991).

Fossil record. Pliocene of Sicily ( Monterosato 1872).
