Description

Adults in the ''Olivella'' species are usually quite small, hence the genus has the common name "dwarf olive". Species of ''Oliva'' are usually larger, but there are exceptions.

The shell of ''Olivella'' usually has a keel-like twist at the anterior end of the columella. The wall above it may be concave or have deep furrows. The inner lip can sometimes show a deep callus, and in many cases this extends over the parietal wall to the end of the aperture. This callus formation may extend to the spire but leave the suture open. Most species of ''Olivella'' have a thin, chitinous operculum, but this operculum is lacking in '' Olivella nivea'', as is also the case in species of ''Oliva''.

(Described as ''Lamprodoma'') The spire is acuminate, elevated with the suture canaliculated. The inner lip is simple posteriorly, regularly and closely plicate at the fore part of the columella. The callus is moderate and restricted.

(Described as ''Dactylidia'') The spire is obtuse, covered with a thick deposit of enamel. The aperture is narrow and plicate. The inner lip has a large, thickened callus, produced at the hind part, and covering and concealing the spire.
