Fig. 4

Scalpellum insigne Hoek, 1883: 68 , pl. II, figs 3–4.

Gymnoscalpellum insigne: Zevina, 1981a: 153–154 , fig. 109.

Material examined. Holotype NHM UK 2013.1067, Stn 6: Atlantic , Northeast (off Cape Sao Vincente, Portugal); 2791 m.

Diagnosis. Hoek (1883) only, no appendage descriptions available.

Distribution. Atlantic, Northeast: off the Azores. Known depth range 2791 m.

Remarks. Newman & Ross (1971) considered this species to be an ontogenetic stage similar to those of other Gymnoscalpellum species , particularly Gymnoscalpellum larvale (Pilsbry, 1907с). Study of the shell plate details confirms that these two species may be closely related, but the appendages have not yet been compared in detail.
