Abstract: There are two jaw specimens, NHG22701 and NHG22703, of rough-toothed dolphin (Steno bredanensis)
in the depot of the Zeeuws Museum (collection Koninklijk Zeeuws Genootschap der Wetenschappen). This
paper describes and depicts them both. We also trace how they came to be in the collection. Specimen NHG22701,

... De Smet (1974) tried to reconstruct how a broken mandible of a roughtoothed dolphin that ended up in a ditch near Bruinisse (Zeeland, the Netherlands) could have been part of the dolphin Van Breda described. However, Heerebout et al. (2014) provide a more plausible explanation for the origin of that mandible, suggesting it was the discarded evidence for the bounty set up by the Dutch government to help support the local fisheries. As such, the whereabouts of the skull of the rough-toothed dolphin Van Breda depicted still remained unknown. ...
Abstract: Van Breda (1829) published the first extensive description of the rough-toothed dolphin Steno bredanensis (Lesson, 1828). The whereabouts of the skull of the dolphin that Van Breda depicted, remained unknown. In the collection of the Ghent University Museum, skulls of three rough-toothed dolphins are present, without information on the locality or date of collection. The positions of the foramina in dorsal view of one of these skulls (MDV50426) perfectly match those in the depicted skull in Van Breda’s publication. Beyond reasonable doubt, this is the specimen described in Van Breda (1829) as Delphinus bredanensis
Lesson, 1828. There are two syntypes referred to in the taxon Steno bredanensis Lesson (1828). The first is the animal later depicted in Van Breda (1829). The second is a specimen from Brest (Brittany, France), however no parts of this specimen seem to be available anymore. Therefore, the rediscovery of the skull MDV50426 is important.
