Cerithium bavaricum v. Ģmbel—Ģmbel in Wolff 1897: 269, pl. 26, fig. 6 [nov. nom. pro Cerithium sandbergeri Gümbel 1861 ].

Type material. Syntypes, Bayerische Staatssammlung f̧r Paläontologie und Geologie, Munich ( Germany) .

Type locality. Rimselrain at T̂lz (Bavaria, Germany) .

Stratigraphy. Late Oligocene/Early Miocene, Egerian.

Discussion. A small species characterized by predominant spiral sculpture on late teleoconch whorls. Kadolsky (1995) treated this taxon at species rank and placed it in Granulolabium . Janssen (1984) considered it to be a subspecies of G. plicatum . Wolff (1897: 269) emphasized that only few specimens were available of which only one was well preserved. Therefore, we tentatively consider it a rare morph of G. plicatum with reduced beads.

This species was described by Ģmbel (1861) without illustration but with a clear description. Ģmbel in Wolff (1897), however, introduced Cerithium bavaricum as new name because he considered that the name given by Deshayes (1864) would have priority because this description was accompanied by an illustration.As the description in Ģmbel (1861) is sufficient to make the name available, Cerithium bavaricum is an unnecessary replacement name (see also Kadolsky 1995: 14) [note that Wolff 1897: 260 clearly states that the name Cerithium bavaricum was given by Ģmbel. Therefore, the authorship of C. bavaricum is Ģmbel in Wolff, 1897)].
