Revision of the genus Goodallia (Bivalvia : Astartidae) with the description of two new species

A revision of the Recent species of the genus Goodallia (Astartidae) is pre sented. Adult shell and prodissoconch morphology of all the species are des cribed and figured. In total, five species are recognized: G. triangularis (Montagu, 1803), G. pusilla (Forbes, 1844), G. macandrewi (Smith, 1881), G. ,micalii new species. and G.gofasi new species. C. tiangularis and G. pusil la are widespread distributed in the Atlantic coasts of Europe and North Af rica, and in the Mediterranean. G. macandrewi is restricted to the type loc ality in the Canary Islands, while what has been called G. macandrewi from the Mediterranean corresponds to an undescribed species here named G. mical ii, distributed in the Central and Eastern Mediterranean. A second undescri bed species from off the Atlantic Moroccan coast is named G. gofasi, and is known only from the type material of station B33 of the expedition CINECA CHARCOT 111. The named forms, variability and distribution of G. triangular is are discussed.
