Stomatella is a genus of small to medium-sized sea snails, marine gastropod mollusks in the family Trochidae, the top snails and their allies.
Lamarck in the Philos. Zool., 1809, mentioned the genus as "Stomatelle" but did not describe the genus, nor did he cite any species. He cited the genus in Anim. s. Vert. vol. vi, p. 209, 1819. with as first species Stomatella imbricata (now a synonym of Granata imbricata (Lamarck, 1816) )
According to the Nomenclator Zoologicus of ubio.org, the authorship should be attributed to Rafinesque., who Latinized the name to Stomatella.
Description
The spiral, orbicularly depressed shell is imperforate. The conical spire is elevated but short. The whorls are rounded but not plicate below the sutures. The last whorl forms the greater part of the shell. The variegated surface is spirally ribbed. The large aperture is wider than the long, nacreous interior. The horny operculum is circular and multispiral.
The foot is truncated posteriorly. There are no epipodial tentacles.
