Nine gastropod genera are described from the Ordovician (upper Ibexian portion) of the Narwhale Sound Formation of Hudson Land in Northeast Greenland. The gastropods have Laurentian affinities, and eight of the Greenland genera described here also occur in the Catoche, Aguathuna or Table Point formations of western Newfoundland. Taxa include Maclurites acuminatus (Billings, 1865), Helicotoma sp. indet., operculum and shell of Ceratopea cf. unguis Yochelson & Bridge, 1957, Lophospira aff. perelegans Stauffer, 1937, Turritoma aff. acrea (Billings, 1865), Hormotoma augustina? Billings, 1865, Straparollina sp., Lophonema taneyensis (Cullison, 1944), and Boucotspira antelopensis (Rohr, 1996).
