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.[2] Labio is a junior homonym of Labio Oken, 1815, itself a synonym of Monodonta Lamarck, 1799[3][4]
The very heavy, thick, solid shell has a turbinate-conic shape. The shell is smooth or spirally ridged. The outer lip is plicate within.
