* Cerithium (Clava) bidentatum Defr. var. fusiformis Schff. — Schaffer 1912: 155, pl. 52, figs 4–6.

Type material. Lectotype designated herein: NHMW 1999z0004/0005, SL: 60.2 mm, MD: 17.7 mm, stored in the Natural History Museum Vienna ( Austria), illustrated in Schaffer (1912: pl. 52, fig. 5).

Type locality. Gauderndorf ( Austria)

Stratigraphy. Early Miocene, Eggenburgian.

Discussion. This species is based on two rather slender specimens of Terebralia lignitarum ( Eichwald, 1830) , but agree with conspecific specimens in sculpture type, strength of varices, height of last whorl and presence of two denticles inside the aperture.

Central Paratethys. Eggenburgian (Early Miocene): North Alpine Foreland Basin: Gauderndorf ( Austria) ( Schaffer 1912).
