Monodonta
''Monodonta'' is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails. 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. Distribution The species of this marine genus occurs over a wide area: Central and East Indian Ocean, Indo-China, Indo-Malaysian Oceania, the Philippines, Japan and Australia (Northern Territory, Queensland, Western Australia).

Monodonta Lugubris
''Monodonta lugubris'' is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails. ''Monodonta lugubris'' is considered by CLEMAM a synonym of ''Phorcus lineatus'' ( da Costa, 1778). Henry Pilsbry Henry Augustus Pilsbry (7 December 1862 – 26 October 1957) was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a cent ..., on the other hand, considered already in 1889 that the name ''lineatus'' of Da Costa, used until that time by many authors, should be considered inadmissible on account of the failure of that author to use generic in combination with his specific names. To add to the confusion, the website gastropods.com considers Monodonta lugubris a synonym of ''Osilinus lineatus lineatus'' Costa, E.M. da, 1778, while WoRMS considers ''Osilinus lineatus'' a synonym of ''Phorcus lineatus''.
