* Pirenella disjuncta (Sow.) var. quadricincta nov. var. — Sieber 1937: 483, pl. 24, fig. D5.

Type material. Lectotype designated by Švagrovský (1971: 337), NHMW 1847/0037/0094, SL. 24.8 mm, MD: 9.7 mm, Natural History Museum Vienna ( Austria), illustrated in Sieber (1937: pl. 24, fig. D5).

Type locality. Ĥflein ( Austria) .

Stratigraphy. Middle Miocene, Sarmatian (Volhynian).

Discussion. This species was established for specimens of P. disjunctus with a fourth beaded spiral cord close to the abapical suture. This morph always co-occurs with typical specimens and a separation is unjustified.
