Olivella thompsoni is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives. [2]
Original description: "Shell small, solid with an elevated spire of about 6 whorls, the first 2 forming a relatively large, blunt nucleus. The body-whorl is fairly large, convex. Sutures are narrowly grooved with a slightly appressed margin in front. Parietal callus narrow and extends to the end of aperture. The pillar structure forms a small, double fold at the end of the pillar, often much heavier within; opposite to it at the lower end of the outer lip, there is sometimes a small liration. Inner wall of the pillar shows no sign of corrosion, its form being normally concave. Surface smooth and polished, white or yellow, sometimes with longitudinal streaks or flammules of brown. Lip simple and unthickened. Length 11 mm., diameter 5 mm." [3]
Locus typicus: "Edge of Pourtalès Platform southward of Sombrero Light
off Marathon, Florida Keys, Florida, USA." [4]
Olivella, common name the dwarf olives, is a genus of small predatory sea snails, marine gastropod molluscs in the subfamily Olivellinae of the family Olividae, the olives. Olivella is the type genus of the family.
Jaspidella mirris is a species of sea snail, a marine gastropod mollusk in the family Olividae, the olives.
Olivella acteocina is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella bitleri is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella broggi is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella cocosensis is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella columellaris is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives. With the very similar Olivella semistriata it forms the subgenus Pachyoliva. Both species are suspension feeders. They use unique appendages of the propodium to deploy mucus nets which capture suspended particles from the backwash on sandy beaches of the tropical eastern Pacific.

Olivella macgintyi is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella moorei is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella morrisoni is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella perplexa is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.

Olivella rehderi is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella riverae is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella semistriata is a species of small sea snail, a marine gastropod mollusk in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives With the very similar Olivella columellaris it forms the subgenus Pachyoliva. Both species are suspension feeders. They use unique appendages of the propodium to deploy mucus nets which capture suspended particles from the backwash on sandy beaches of the tropical eastern Pacific. Olivella semistriata is a swash-surfer; the snails use their expanded foot as an underwater sail to follow the tidal movement of the backwash zone in which they feed.
Olivella stegeri is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella watermani is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Pachyoliva is a subgenus of small sea snails, marine gastropod mollusks in the genus Olivella, the dwarf olives, within the family Olividae, the olives. Species in this subgenus inhabit soft sediments in the intertidal and subtidal zones of sandy beaches of the Panamic faunal province, that is, the west coast of the Americas from Baja California to north Peru.
