Cepaea cf. sylvestrina : Salvador, 2013b: 163 (figs. 14–17).

Material examined. BSPG 1952 XVIII 49 (10 spcm.).

Description. Shell large, 4¼–4½ whorls, helicoid; whorls regularly growing. Protoconch flattened, smooth; transition to teleoconch unclear. Teleoconch smooth, except for growth lines. Whorl profile flat on first whorls. Suture well-marked. Body whorl slightly bent downwards. Aperture prosocline, crescent-shaped; callus faint. Peristome markedly thickened and reflexed. Umbilicus imperforate.

Previous identification of the material. Gall (1980: Nr. 16): Cepaea silvana silvana (Klein) .

Discussion. The specimens from Gündlkofen compare reasonably well with C. sylvestrina , but are slightly larger, with one quarter to one half additional whorl when compared to typical C. sylvestrina ; nevertheless, this species seem to be quite variable morphologically. Cepaea silvana Klein , another common species in the German Middle Miocene, is even smaller, with fewer whorls and a more rounded overall profile, and might be simply a morphological extreme of C. sylvestrina .

Paleoecological remarks. As C. cf. eversa above.
