The morphology and stratigraphic importance of species, subspecies and varieties of the genus Gavelinella from the Senonian (Upper Cretaceous) chalk of north-west Europe are discussed. It is suggested that several stratigraphically significant lineages arose from a Gavelinella schloenbachi (Reuss) ancestor during the Senonian. Within the Gavelinella clementiana (d'Orbigny) plexus of evolving forms, one subspecies G. dementiana convexa is described as new. The Gavelinella lorneiana (d'Orbigny)-G. pertusa (Marsson) lineage is regarded separately, and it is suggested to have arisen from a Gavelinella ammonoides (Reuss) ancestor during the Turonian.
