Habitat: it is an infralittoral species. It prefers muddy-detrital bottoms. Distribution: common all over the Mediterranean.
Notes: shell easy in determination, slim in form, bright, whorls not much convex, suture broad and undulating. Axial sculpture made by about 15 ribs not much inclined, sinuous, as wide as the interspaces. This species characteristic is that it has no spiral sculpture. External lip thickened. Protoconch, brown in colour, is paucispiral, with about two whorls smooth. Changeable colour pattern: the most common chromatic dress is a ground beige in colour either with numerous little lines or little bands brown, but there are also mono-chromatic specimens. In literature it is known a subspecies pusilla (Scacchi, 1836) characterized by a bigger number of axial ribs. Pre-mature forms have almost the same adults outline. Its similar ones, with paucispiral protoconch and without spiral sculpture, M. sandrii (Brusina, 1875) and M. taeniata (Deshayes, 1835), are easily recognizable since they are less slim in outline, they have a different chromatic dress and a smaller number of axial ribs, which are also in different form and consistence, and smaller an sizes. The adult specimens average measures are around 8 mm in height.
