Peristernia violacea

Peristernia violacea is a species of sea snail, a marine gastropod mollusk in the family Fasciolariidae, the spindle snails, the tulip snails and their allies. It is characterized by a silver or gold periostracum that is iridescent when wet, and a deep violet aperture. It is possibly endemic to the Line Islands, and is recorded from Palmyra, Kiritimati, and other nearby islands, although collections from the Andaman Islands have been tentatively identified as this species.[1]

Description

Fairly small, 20 to 35 mm in length. Characterized by a silver or gold periostracum that is iridescent when wet, and violet aperture. Pease referred to the iridescence as greenish silver.

Distribution

Line Islands, Palmyra and eastern Kiribati. Additional specimens tentatively identified as this species recorded from Andaman Islands, a distribution gap of approximately 7,500 miles (over 12,000 km) if correct. Alain Robin's "Compendium of Marine Gastropods" correctly illustrates the species, but the illustrated specimen is from Christmas Island, Kiribati, not from the Andaman Islands as stated in the text.
