Subgenus Manzonia Brusina, 1870

Type species: Turbo crassus Kanmacher in J. Adams, 1798 from the West Mediterranean and NE Atlantic .

Remarks.—The subgenus Manzonia differs from the subgenus Alvinia by teleoconch whorls narrowing towards the aperture, thus separated by deep sutures and by a teleoconch sculpture of prominent, rounded, strongly opisthocline axial ribs crossed by much weaker spirals.
