CURRENT TAXONOMIC STATUS. — Amastrinae, Amastra (Metamastra) . Valid species.

TYPE LOCALITY. — “îles Sandwich”.

REMARKS

Férussac in Quoy & Gaimard (1825: 482) did not illustrate the species and provided only a short description, and it was not treated by Deshayes (1851). It is therefore difficult to ascertain the status of the MNHN specimens. Hyatt & Pilsbry (1911 [in 1910-1911]: 165) stated that the “type specimens” were in the “Jardin des Plantes” (i.e. MNHN). The labels associated with the MNHN specimens indicate that they are from the Deshayes collection, and therefore possibly Férussac’s collection. They are therefore treated here as probable syntypes only.
