This paper is a continuation of Warén’s articles in Sarsia volumes 74, 76, and 78. Mikro globules gen. et sp.n. (Archaeogastropoda, provisionally in Skeneidae) is described from the Icelandic shelf and Anekes giustii Nofroni & Bogi, 1989 from the Mediterranean is transferred to this genus. Protolira thorvaldsoni sp.n. (Archaeogastropoda, Skeneidae) is described from decaying whale bone found off southwestern Iceland. Coccopigya lata sp.n. (Archaeogastropoda, Cocculinidae), Alvania angularis sp.n. and A. incognita (Mesogastropoda, Rissoidae) are described from sunken drift wood from deep water off Iceland. Onoba improcera sp.n. and O. torelli sp.n. (Mesogastropoda, Rissoidae) are described from northern Iceland. ‘Cingula’ globuloides Warén, 1972 (formerly in Rissoidae) is transferred to Elachisina (Mesogastropoda, Elachisinidae). Alvania alaskana (Dall, 1887) and Alvania dinora (Bartsch, 1917), both from Alaska, are synonymised with Onoba mighelsi (Stimpson, 1851) (Mesogastropoda, Rissoidae). Brookesena turrita sp.n. (Heterobranchia, Mathildidae) is described from several localities around the Icelandic upper continental slope and Turritellopsis stimpsoni Dall, 1919 (formerly known as T. acicula (Stimpson, 1851), Mesogastropoda, Turritellidae) is transferred to the Mathildidae. All northeast Atlantic species of Rissoidae (Mesogastropoda) except the genera Rissoa and Pusillina are reviewed, and their distribution and habitat is given. Substantial extension of the distributional range is given for the following Gastropoda: Granigyra inflate (Warén, 1992), off southwestern Iceland ca 1000 m. Lissotesta turrita (Gaglini, 1987), off southwestern Iceland ca 1200 m. Xyloskenea naticiformis (Jeffreys, 1883), on sunken driftwood, off southwestern Iceland ca 1200-1800 m. Basilissopsis watsoni Dautzenberg & Fischer, 1897, off southwestern Iceland ca 1000 m. Cingula trifasciata (J. Adams, 1800), Swedish west coast, Gullmarsfjorden (empty shells). Pseudosetia turgida (Jeffreys, 1870), off southeastern Iceland. Boreocingula castanea (Møller, 1842), Varangerfjord, northern Norway. Boreocingula globules (Møller, 1842), restricted to southwestern Greenland. Benthonella tenella (Jeffreys, 1867), off southern Iceland. Alvania moerchi (Collin, 1886), northern and eastern Iceland. Alvania subsoluta (Aradas, 1847), northern and southwestern Iceland. Alvania pseudosyngenes Warén, 1973, northern Iceland, 400-200 m. Manzonia crassa (Kanmacher, 1798), Swedish west coast (empty shells) and Norway to 60.5° N Crisilla semistriata(Montagu, 1808), Swedish west coast (empty shells) and western Norway to 63.5° N. Onoba exarata (Stimpson, 1851) is recorded from northern Iceland. |
