ART INS 1993. Notes on some rare and little known marine invertebrates from the Azores, with a discussion of the zoogeography of the region.-Arquipdago. Life and Marine Sciences 11A:55-63. Angra do Heroismo. ISSN 0870-6581. We briefly comment on the occumence of the following marine invertebrate species in Azorean waters: the molluscs Pleurobranchus testudinarius, Aplysia fasciata, Diaphorodoris luteocincta, Discodoris arromaculara, Platydoris argo, Polycera elegans, Tambja ceutae, the crustaceans Lysmata nilita, Eualus occultus, Aristaeomorpha foliacea, Aristeus aMennatus, Cycloes cristata, P i l m u s hirtellus, Polybius henslowii, the phoronid Phoronis cf. hippocrepia, the echinoderm Brissus unicolor are all new records. Some notes are also made on the bivalve &ria hirundo, the crustaceans Plesiopenaeus edwardsianus, Liocarcinus mannoreus, Plagusia depressa, Inachus phalangiurn, Albunea carabus, the echinoderm Centrostephanus longispinis, and the tunicate Clavelina lepadifomis. The 16 new records confirm the well established concept of the "Mediterranean character" of the littoral fauna and flora of the Azores. WIRTZ, PETER & HELEN R. MARTINS 1993.
