( Fig. 59 )

1872 Triton Grasi Bellardi – D’ANCONA, p. 70.

2009 Personopsis grasi (d’Ancona) – LANDAU et al., p. 79, pl. 9, figs 5–7.

Material – One fragmentary specimen (SL 20); in private collection.

Description – Fusiform shell, elevated spire, six weakly convex teleoconch whorls, regularly convex last whorl. Subtrigonal aperture, denticulate outer lip thickened by labral varix, strongly excavated columella, thick parietal callus. Spiral sculpture of three narrow cords on the spiral whorls and 11 on the last whorl, fine threads, axial sculpture of about 16 rounded ribs, one weak varix per whorl.

Remarks – The Paratethys specimens differ in morphology from their Pliocene descendants in Italy by smaller and narrower shell with finer ornamentation. The species is very rare in the Paratethys. P.grasi is a new record in Hungary.

Distribution – Badenian: CP ( Austria, Hungary, Romania), Tortonian: PMS ( Italy). For Pliocene-Recent range see LANDAU et al. (2004).
