Material examined

Paralectotype MCZ 7707 of Paradentalium gouldii   ; IBUFRJ 10796, sta C 76, 4 dd; IBUFRJ 14297, sta A 3, 1 dd; IBUFRJ 14298, sta C 13, 2 dd.

Distribution

USA: South Carolina ( Dall 1889); Puerto Rico ( Henderson 1920); Surinam ( Altena 1971); Colombia ( Gracia et al. 2005); Brazil: off Amapá ( Scarabino 1994), Bahia and Espírito Santo (this study). No specimen recorded alive; shells recorded 47– 260m.

Remarks

Paradentalium gouldii   shares the outline with P. americanum (Chenu, 1843)   , with hexagonal section at apex and aperture, differing in having intercostal spaces longitudinally sculptured by very fine striae. One of the paralectotypes, MCZ 7707, is much eroded making it impossible to verify the longitudinal sculpture ( Fig. 6 View FIGURES 1 – 19 ). Pilsbry and Sharp (1987) suggest the synonymy between P. gouldii   and P. americanum   , but at this moment we prefer to treat them as valid species and our specimens are identified as Paradentalium gouldii   mainly because of the presence of longitudinal sculpture between ribs.
