Perrierina is a genus of marine bivalve molluscs of the family Cyamiidae.[1] Members of the genus are found in the waters of New Zealand, Australia and Antarctica.
Description
[edit]Members of Perrierina have small, thin shells that are transversely-ovate and inequilateral (the anterior side being significantly shorter). The genus has a cap-shaped prodissoconch and shallow hinge plates, that have pairs of small cardinals in each valve.[2]
Taxonomy
[edit]The genus was first described in 1897 by Félix Bernard.[3] The genus was originally monotypic, only including P. taxodonta, until 1928 when P. ovata was described.[4]
Distribution
[edit]Perrierina is primarily found in the waters of New Zealand,[5][6] with additional species known to occur in south-eastern Australia and Antarctica.[7][8] The earliest currently known fossils of the genus, Perrierina sola, date to the Opoitian stage of the Pliocene in New Zealand (approximately 5.33 million years ago),[9] with similarly aged fossils found on King George Island of the South Shetland Islands.[8]
