OSORIO, Cecilia y REID, David G.. Intertidal and subtidal marine molluscs between Boca del Guafo and Elefantes Fjord, southern Chile. Investig. mar. [online]. 2004, vol.32, n.2, pp. 71-89. ISSN 0717-7178. doi: 10.4067/S0717-71782004000200006.
A study was made of marine molluscs collected in the fjord region of southern Chile, including the Jacaf and Puyuhuapi channels, Aysen Sound and the Quitralco and Cupquelan fjords. Samples were obtained during the Cimar 7- Fjords research cruise, of 8-20 July 2001. Collections of benthic samples were made between Boca del Guafo and the Elefantes fjord. Samples were taken by hand with an Agassiz trawl from 20 stations at various depths between 0 and 330 m. A total of 22 species were recorded (1 polyplacophoran, 7 gastropod, 12 bivalve and 2 scaphopod). Of these, 19 are described and illustrated, together with new information on habitat and geographical distribution. We report new geographical records for the following seven species: Calliostoma nudiusculum, Calliostoma consimilis, Capulus compressus, Falsilunatia patagonica, Aeneator fontainei, Fissidentalium majorinum and Rhabdus perceptum, six of these are northward extensions of the magellanic molluscan fauna while the record of Aenaeator fontainei is a new southern limit
