[dubious species]
Overview
This is a large shelled, pelagic snail. It lives in the pleuston and has no swimming fins. The dextral shell is highly coiled. The aperture is round, the columella is straight. It is a carnivorous species predating on relatively large floating animals.
Taxonomic Description
In this species the whorls are more convex than in R. turrita v.d. Busch, which it closely resembles. The straight, elongated inner lip has the free margin somewhat reflexed; the aperture is produced anteriorly, and the whorls are transversely striated. The nucleus is small and pointed and the nuclear whorls are quite pellucid.
Juveniles
The juveniles have a dextrally coiled shell. A special description is not available.
