About Brown Purse Shell
Bishop Museum TR29 records Isognomon perna at Kauai coastal stations.
MolluscaBase/WoRMS AphiaID 208470 accepts Isognomon perna.
TR29 is a coastal marine survey within scope; two 2025 Kauai observations are annotated dead and therefore do not establish current living presence.
Authoritative historical occurrence is verified, while modern records explicitly represent dead material.
