Taxonomic study on the molluscs collected in Marion-Dufresne expedition (MD 55) to SE Brazil: Xenophoridae, Cypraeoidea, mitriforms and Terebridae (Caenogastropoda) Simone, Luiz Ricardo L.

However, nothing more precise than the generic attribution is possible, as the identification of lamellariid species, only based on the vestigial shells, is complicated. Anyway, the shells of the three lots appear to belong to different species. Those of the MNHN lot (stn DC73) are more rounded and with a thicker-walled shell ( Fig.3G, H). The shell of the MNHN lot(stn DC77) is more elongated and thinner-walled. And the shells of the MNHN lot (stn DC70) are oval, with a wider aperture, and possess delicate transverse undulations on the last whorl. The first indication is that the three lots may represent different species, which only can be defined with additional samples. Family PEDICULARIIDAE Gray, 1853
