This genus formerly belonged to the family Tricoliidae.
Description
This genus consists of small species with a head without frontal lobes. The shell is ovate, elongated, and imperforate. The
radula has a broad, simple median tooth, overlying the bases of the inner laterals. These are subrhomboidal, produced at their outer angles into wings which overlie the bases of the adjacent tooth outward, and have denticulate cusps. The outer lateral is narrow, not produced on the outer angle. The marginal teeth have long simple cusps, The
columella is smooth, arcuate, and not dentate.[2]
Distribution
The species occurs in all tropical and subtropical seas.
