Habitat: it is an infralittoral species. It prefers muddy-detrital bottoms. Distribution: common all over the Mediterranean.
Notes: this species is included in the group with polygyral protoconch and spiral sculpture missing. Shell bright, slim in outline, whorls not much convex, suture broad and undulating. Axial sculpture made by 10-11 ribs a little bit sinuous, as wide as the interspaces. Aperture inflated, external lip thickened. Last whorl about two thirds of total height. Ground white-grey in colour, with typical spiral little lines, brown in colour and one band below-suture brown in colour. Apex, protoconch and first whorls of teleconch dark brown. Even the two little stains inside peristome, brown in colour, are characteristic ones. M. vauquelini (Payraudeau. 1826) and M brusinae van Aartsen & Fehr-de Wal, 1978, with the same kind of protoconch and spiral sculpture missing, are its similar ones, from which it is recognizable these last ones having one strong shoulder of the axial ribs near suture. Moreover brusinae has a really different chromatic dress and a different distribution. Juvenile specimens are more angular in outline but they are easily recognizable. The adult specimens average measures are around 6 mm in height.
