Ventrilia trochlearis ( Faujas, 1817) — Cahuzac et al. 2004: 224, figs 3P–S [cum syn.].

Type material. the type from the Early Miocene of France is lost ( Cahuzac et al., 2004)

Discussion. Hölzl (1958) introduced disparstriata and gravecostata as variety names of Ventrilia trochlearis ( Faujas, 1817) for shells from the Early Miocene of Bavaria. The preservation of that material is poor but the general shape and sculpture agree with French specimens of Ventrilia trochlearis ( Faujas, 1817) as described by Peyrot (1928) and Cahuzac et al. (2004). For an illustration of the Paratethyan representatives see Hölzl (1958).

Distribution. This species is widespread during the Early Miocene from the North East Atlantic to the Paratethys.

North East Atlantic — Early Miocene: Aquitaine Basin ( France: Aquitaine Basin) .

Proto –Mediterranean Sea —Burdigalian: Colli Torinesi: ( Italy).

Paratethys — Eggenburgian and Ottnangian: North Alpine Foreland Basin (Bavaria: Gernergraben, Kaltenbachgraben) .
