rollei . Cerithium . Hilber, 1879a see Theodisca theodisca ( Rolle, 1856)

* Cerithium Rollei Hilb. — Hilber 1879a: 24, pl. 4, figs 4a–c.

Type material. The holotype was stored at the Universalmuseum Joanneum (Graz, Austria) but is lost .

Type locality. Gamlitz ( Austria) .

Stratigraphy. Middle Miocene, Badenian.

Discussion. The specimen illustrated by Hilber (1879a: pl. 4, figs 4a–c) does not differ from other specimens of Theodisca theodisca ( Rolle, 1856) which occurs at Gamlitz in large numbers. Therefore, we treat it as a subjective junior synonym of T. theodiscus .
