The Upper Miocene gastropods of northwestern France. Part 8: fine, addenda and corrigenda

In this paper we conclude the taxonomic revision of the gastropods of Assemblage I (sensu Van Dingenen et al., 2015) of the Upper Miocene Tortonian of northwestern France. Additions and revisions to previous parts of the work are included resulting in the description of nine new species: Palazzia omalogyroides nov. sp., Skeneoides karrineae nov. sp., Alvania praetermissa nov. sp., Setia minutissima nov. sp., Cerithiella bisulcata nov. sp., Ophieulima ligeriana nov. sp., Costoanachis haurzhauseri nov. sp., Suluspira gallica nov. sp., and Andonia fosseensis nov. sp.. Bolma redoniana nov. nom. is proposed for Turbo trochleatus Millet, 1865, non zu Münster, 1841.
