Abstract

Marine Quaternary mollusks are reported from Santa Catalina, Confital Isleta, Alcarabanares and Agaete, all on the Island of Grand Canary. The three former localities which are near Las Palmas, can probably be correlated with the Ouljian deposits of Morocco (=Tyrrhenian II of the Mediterranean). The Agaete locality may be older and may possibly be correlated with the Maarifian of Morocco (=Tyrrhenian I). Shells from Confital have been dated by the ionium method as 100,000 ± 30,000 B. P. Some 86 species of gastropoda and 27 species of pelecypoda are listed from these deposits. This list includes specimens collected by previous workers as well as those collected by the present writers. Species of special significance include Strombus bubonius Lamarck (=S. latus Gmelin), Purpura haemastoma L. and Purpura (Acanthina) crassilabrum Lamarck. Several localities are discussed from the Island of Lanzarote and a fauna of 64 species of gastropods and 37 species of pelecypods are listed. Beaches are reported up to an elevation of 55 m and there is morphological evidence of beaches up to 160 meters. The best developed shoreline on the Island of Fuerteventura is at 16 m, although there is morphological evidence of higher beaches.
