The analysis of shell grit samples taken between 0 and 50 m from Faial, Pico and Sao Miguel revealed the presence of seven not yet reported marine species of molluscs from the Azores Archipelago, four gastropods species [Caecum swinneni Nofroni, Pizzini & Oliverio, 1997(Caecidae), Granulina cf. canariensis Boyer, 2001 (Marginellidae), Mitromorpha engli Mifsud, 2001 (Mitromorphidae), Discotectonica discus (Philippi, 1844) (Architectonicidae)] and three species of bivalves [Acar clathrata (Defrance, 1816) (Arcidae), Rhomboidella canariensis (Odhner, 1932) (Mytilidae) and Kelliopsis jozinae van Aartsen & Carrozza, 1997 (Lasaeidae)].These species are considered today as part of the Archipelago's fauna and illustrated here.
