Distribution of Lioihyris nrctica (Friele), Occurrence: Between Iceland and Greenland: 67°03' N. 27°08'W.; 1 spec. — "Ingolf" St. 78; 60°37' N. 27°52' W.; 1500 m; 1 spec. - Between Jan Mayen and Greenland: 7417' N. 15°25'W.; 250 m; 6 very large specimens. — 70°21'N. 18°25'W.; 315 m; 2 spec. — Jan Mayen: mud; 3 spec. The shells of this small species are sernitransparent, very brittle and therefore often broken when taken by the dredge. The beak is short, slightly incurved, the deltidial plates almost rudi- mentary, the ventral valve much deeper and more oblong than the slightly convex and nearly circular dorsal valve. The brachial loop is very small and fragile. All the specimens are typical; the only point worth mentioning is that three of the 6 specimens from one of the "Danish East- Greenland Expeditions" (74°17' N. 15°25'W.) are unusually large: dorsal valve about x 12 mm, ventral valve about 15 X 12 mm. The new localities offer little of interest, as they are on the whole within the area of distribution of the species previously known. The locality at GO 37' N. Lat. represents the southern- most locality hitherto known. The species was originally described by Friele from Jan Mayen; he states that it is abundant some few miles south-west ni' thi^ island. Later on it has been recorded from several loca- lities along the east coast of Greenland, where it is even found in the fjords. Grieg (1920, p. 18) reports it from Spitsbergen, but later on (1933, p. 67) he himself states this to be a mistake. The species is holarctic and restricted to the western part of the Norwegian Sea and the area between East-Greenland and Iceland. It is a pronouncedly abyssal form. The Terebratellid Group.
