MATERIAL AND DIMENSIONS. — Maximum height 2.7 mm (incomplete), width 2.1 mm.— RGM.1364982 (1), leg. ACJ ; RGM.1365184 (2), leg. ACJ .

SPECIES CHARACTERISATION. — Small, ovate-conical shell with subobsolete spiral threads. Four teleoconch flat whorls. Last whorl is 59% of the total height. Prosocline growth-lines. Ovate aperture, with open umbilicus.

DISTRIBUTION. — Selsoif, NW France (this paper).Today L. vincta is found in boreal regions of western and eastern Atlantic Ocean with its southern distribution recorded in Brittany ( Smith 1973) where it is common on algae such as Fucus .

REMARKS

We have only badly damaged material, whose attribution is uncertain. Nevertheless, the flat-sided whorl profile and subobsolete spiral threads suggest it concerns this species.
