Lectotype NHM 1878.3.26.11a.

Material examined: NHM 1878.3.26.11a, b, d.

Diagnosis: polyp—solitary with 1 whorl of 4 cusps.

Description: Based on original description, and Morandini & Jarms (2012). Only known from the polyp stage. Polyp 4.56 mm in total length; a single series with 4 internal quadratic cusps.

Type locality: S of Greenland (56°11’N 37°41’W), ~ 2650m depth GoogleMaps .

Distribution: Only known from type locality.

Remarks: The precise identification of this species demands visualization of the internal cusps (shape and number). We analyzed one specimen previously identified as N. simplex ( NMNH 53831— North Carolina / USA 1966), but observation of the internal cusps to confirm the identification was not possible without damaging the specimen.
