The current historical paper dated back in 1892, is available online through the Biodiversity Heritage Library at https://www.biodiversitylibrary.org/page/10122164#page/379/mode/1up (pages 363-373). Its original title is "Campagne de la Melita, 1892. MOLLUSQUES RECUEILLIS SUR LES COTES DE LA TUNISIE ET DE L'ALGÉRIE, par Ph. DAUTZENBERG, ancient President de la Société". This dataset presents dredging sampling events carried out by researchers off the north coast of Tunisia and Algeria, at several depths. The digitization and standardization process are related to the list of stations sampled and the species - belonging to Phyllum: Mollusca (classes: Pelecypoda, Scaphopoda, Gastropoda,) and Brachiopoda - found. This historical paper is digitized through a Citizen Science Workshop organized by the Hellenic Centre in Marine Research in Lecce, on 15 November 2023, using the Zooniverse platform.
