Chrysallida (Parthenina) eximia (Jeffreys) - Winckworth 1932; Høisaeter 1986

Type material: 25 syntypes, USNM 131880 .

Type locality: Off Lerwick, Shetland.

Material seen: Norway - Skagerrak, 1 sh; Hordaland, 27 spms; Norwegian Trench (83.11.17.5, 61°30’N, 311 m), 4 spms; Møre og Romsdal 6 spms, 10 shs; Nord-Trøndelag, 7 spms, at least 14 shs; Nordland, 5 spms, at least 20 shs; Troms 1 sh.

Diagnosis: Shell: Strongly convex whorls with orthocline axial ribs and three strong spiral cords. Protoconch high with a coarse surface. Soft parts: Pigmented mantle organ (Figure 23, based on a single observation) an orange oval with a white circle embedded. Operculum: Not studied.

Biology: Not known.

Distribution: In Norway found along the whole coast, including east Finnmark (G.O. Sars 1878, Norman 1902), although only occasionally north of Lofoten. Although reported from both Oslofjorden and Skagerrak by G.O. Sars (1878), I found no specimens in my material from Skagerrak. North of Hordaland, surprisingly few specimens found compared to the hundreds (at least 250) of empty shells. Outside Norway only reported from southeastern Greenland, Iceland, the Faroes, Swedish west coast, east of Shetland, western Scotland and a single shell from west of Ireland, 764 m (Jeffreys 1867, Fretter et al. 1986, Warén 1991, Schander 1995).
