Contains: Pleurotomaria, Perotrochus.
The Pleurotomarioidea, slit shells, are a group of marine gastropods represented in the modern fauna only by the family Pleurotomariidae. Members of this group have a shell with a labral slit, followed by a corresponding selenizone (Bouchet et al. 2005). The Pleurotomariidae have a trochiform shell and are restricted in the modern fauna to deeper waters where they feed primarily on sponges.
