Revision of the gastropod family Pseudolividae from the Paleocene of West Greenland and Denmark

The Paleocene deposits on the Nuussuaq peninsula (West Greenland) contain three new species belonging to the family Pseudolividae de Gregorio, 1880. Popenoeum lacunosum sp. nov., Pseudoliva praetermissa sp. nov. and Fusulculus nanapullus sp. nov. are described. The species Fusulculus koeneni (Ravn, 1939) from the Paleocene (Selandian) of Denmark is revised, a lectotype is designated and new figures are published.Pseudoliva (Fusopsis) canalifera Ravn, 1939 is excluded from the Pseudolividae and Fusopsis is considered to be a subjective junior synonym of Suessionia Cossmann, 1889, and therefore reassigned to the family Buccinidae Rafinesque, 1815.
