REMARKS

The present samples contain only full grown specimens of Neoscalpellum debile . This species has been commonly dredged on both sides of the North Atlantic between 2321 and 5318 m (Gruvel 1920; Pilsbry 1907a as Scalpellum dicheloplax; Newman & Ross 1971; Young 1998a, b). It was also recorded in the South Atlantic: off Tristan da Cunha, Angola, and Brazil (Foster & Buckeridge 1995 as Meroscalpellum bifurcatum [Zevina, 1973] [Young 1999]).
