* Cerithium eichwaldi R. Hoernes und Auinger nova forma — Hilber 1882: 7, pl. 1, figs 12, 13.

Type material. Lectotype designated herein: Geological Survey, Vienna ( Austria), illustrated in Hilber (1882: 7, pl. 1, figs 12a–b). The specimen was stored at the Geological Survey Vienna ( Austria) but seems to have been destroyed during World War II (pers. comm. Irene Zorn, February 2022).

Type locality. Golubytsya ( Ukraine) .

Stratigraphy. Middle Miocene, Badenian.

Discussion. Differs from typical Pustulosia submitralis by the presence of a prominent central spiral cord. This feature is rather variably as documented by the various specimens described as Potamides eichwaldi by Friedberg (1914) and does not justify a separation at species level. Hilber (1882) referred to a name given on labels in the collections of the Natural History Museum, Vienna. Therefore, authorship has to be passed to Hilber (1882).
