The genus ''Monodonta'' was first separated from the Linnaean genus ''Trochus'' by Lamarck in 1801 with ''Trochus labio'' Linnaeus, 1758 given as the type species. ''Labio'' is a junior homonym of ''Labio'' Oken, 1815, itself a synonym of ''Monodonta'' Lamarck, 1799 Description The very heavy, thick, solid shell has a turbinate-conic shape. The shell is smooth or spirally ridged. The outer lip is plicate within. The short, porcellanous columella is strong, cylindrical, bulging or more or less toothed near or at the base. Between this tooth and the basal margin there is a square notch or channel. The aperture is as high as wide.
