Revised description (based on Paratethyan material). Shell large, slender fusiform with distinctly incised suture. Protoconch poorly preserved in all available specimens; high conical of about three moderately convex whorls. Teleoconch of ten whorls. First teleoconch whorl with five close-set spiral cords, crossed by weak axial ribs, forming weakly cancellate sculpture. Six to eight broad, flattish spiral cords on subsequent spire whorls; number increasing by bifurcation of some primary spiral cords in variable manner; bifurcated adsutural primary spiral cord in many specimens; Spiral grooves variable in width; very narrow, punctate or slightly wider with delicate, densely spaced axial riblets in most specimens. Last whorl high, weakly convex at periphery, situated slightly above adapical termination of aperture. Slowly contracting, with shallow concavity at base. Spiral sculpture of last whorl variable; typically with 15 to 20 broad spiral cords; on base and fasciole narrower cords with intercalations of secondary spirals. Spiral cords may be weak or subobsolete along periphery. Adapical spiral cords frequently bifurcated. Aperture narrow, elongate. Columellar callus thin, glossy. Columella with four oblique columellar folds, fourth abapical fold strongly reduced in adult specimens. Siphonal canal long, moderately narrow, weakly twisted to the left, with moderately incised siphonal notch. Colour pattern in UV light not intense, consisting of dark-violet spiral stripes coinciding with spiral grooves (not illustrated).

Shell measurements and ratios. SL = 34.7–91.2 mm, MD: 8.9–22.2 mm, AA = 23–28°, SL/ MD: 3.9–4.4, AL/AW: 6.8–7.1, AH/S: 1.8–2.0.

Discussion. Mitra orientalis was introduced by Oppenheim (1918) referring explicitly to the specimens illustrated in Hörnes (1852b, pl. 10, figs 14, 15, 17). Therefore, Mitra orientalis cannot be treated as nomen nudum as proposed by Janssen (1972: 43). The new name is problematic in two aspects. Firstly, it was already preoccupied for an extant Mitridae by Griffith & Pidgeon (1834: 598, pl. 40, fig. 5). Secondly, the three syntypes are not conspecific. Figure 15 View FIGURE 15 of Hörnes (1852b, pl. 109) is treated herein as Cancilla praescrobiculata ( Toldo, 1889) and figure 17 is described herein as Domiporta turpis nov. sp. The status of the giant specimen illustrated as figure 14 by Hörnes (1852b, pl. 10) remains unclear because the specimen is lost. The enormous size of 120 mm is reminiscent of large Pliocene specimens of Cancilla scrobiculata ( Brocchi, 1814) . Hörnes (1852b: 101) states Baden as locality, but this locality may have been erroneous and the specimen originating from the Pliocene of Italy. To clarify the confused situation, we choose the specimen illustrated by Hörnes (1852b, pl. 10, fig. 15) as lectotype of Mitra orientalis Oppenheim, 1918 [non Griffith & Pidgeon, 1834], but refrain from introducing a replacement name for it, because we consider it a subjective junior synonym of Mitra praescrobiculata Toldo, 1889 .

Cancilla praescrobiculata is a common species in deeper water deposits of the Central Paratethys. It is considered the Miocene ancestor of the Pliocene Cancilla scrobiculata ( Brocchi, 1814) by Toldo (1889), Davoli (2000) and Landau et al. (2013). For discussion on differences between the species see Landau et al. (2013: 212).

Palaeoenvironment. The specimens were collected from basinal clays of the Baden Formation, indicating middle to outer neritic environments with up to 250 m water depth ( Hohenegger et al. 2008).
