Monodonta is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails.{{WRMS species|153532|Monodonta Lamarck, 1799||15 March 2011}}

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[http://clade.ansp.org/obis/search.php/6433 OBIS: Labio Oken, 1815]Moore, R.C. (1964). Treatise on Invertebrate Paleontology. Part 1. Kansas : University of Kansas Press and Geological Society of America. Vol.1

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.[https://archive.org/details/manualofconcholo111tryo Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia]
