Records of Opalia-like mollusks (Gastropoda: Epitoniidae) from the Indo-Pacific

This dataset is from a paper by Emilio Garcia (2004) on some new records of Opalia-like mollusks from around the Indo-Pacific region. Many Indo-Pacific species of the epitoniid supraspecific taxa Gregorioiscala and Opalia are recorded, with range extensions for Gregorioiscala burchorum (DuShane, 1988), G. nierstraszi (Schepman, 1909), Opalia alba (de Boury, 1911), O. bicarinata (Sowerby, 1844), O. pupipunctata (de Boury, 1911), and O. sumatrensis (Thiele, 1925). This study is a continuation of an earlier publication on new records of Indo-Pacific Epitoniidae (Garcia, 2003), in which extensions of known geographical ranges of a number of epitoniid species and the description of nineteen new species were reported. The material used in both of these reports was obtained as a result of expeditions by the Institut de Recherche pour le Développement (IRD, Nouméa) and the Muséum National d'Histoire Naturelle (MNHN, Paris).
