MATERIAL AND DIMENSIONS. — Maximum height 2.1 mm, width 0.9 mm. — RGM.1365019 (4), leg. ACJ ; RGM.1365213 (1), leg. ACJ .

SPECIES CHARACTERISATION. — Small, solid shell. Protoconch not preserved. Five teleoconch whorls, spire telescopic, whorls weakly convex, surface appears smooth (abraded). Outer lip prosocline in profile and arched. Small columellar fold. Narrow umbilical chink.

DISTRIBUTION. — Upper Miocene: Atlantic, NW France ( Landau et al. 2020a). — Upper Pliocene: western Mediterranean, Estepona Basin, Spain ( Landau & Micali 2021). — Lower Pleistocene: Atlantic, Selsoif, NW France (this paper).

REMARKS

This seems to be the same species as that recorded by Landau et al. (2020a) from the Upper Miocene of NW France and Landau & Micali (2021) from the Upper Pliocene Estepona Basin of Spain as Ondina cf. micropeas ( Boettger, 1902) .Unfortunately, the Pliocene specimens from Estepona and the Selsoif material do not have their protoconchs preserved enabling comparison with the Assemblage I material from NW France. Nevertheless, they share the relatively solid shell, telescopic spire, small columellar fold and narrow umbilical chink.
