Type material. Holotype: M277 , Mining and Geological Survey of Hungary, Budapest, SL: 18.5 mm, MD: 17.5 mm, Herend ( Hungary), illustrated in Kókay (1966: pl. 7, fig. 10), Figs 3A View FIGURE 3 1 –A View FIGURE 1 4 View FIGURE 4 .

Illustrated material. NHMW 2024/0229/0001, SL: 28.8 mm, MD: 25.6 mm, Weitendorf ( Austria), Figs 3B View FIGURE 3 1 – B View FIGURE 1 4 View FIGURE 4 .

Revised description. Medium sized, globose, robust shell of ~4.5 teleoconch whorls; as high as wide ( SL /MD = 1.0). Protoconch unknown. Spire moderately elevated, gradate; apical angle 115–130°. Suture linear, adpressed. Teleoconch whorls with broad, flat subsutural shelf delimited by very prominent shoulder. Last whorl moderately expanding, attaining ~95% of total height, weakly convex below shoulder and at periphery. Periphery placed just below mid-whorl (~47%). Base weakly convex, nearly conical. Growth lines delicate, weakly prosocyrt in apical view, prosocline and subobsolete at periphery. Aperture wide D-shaped, prosocline. Adapical tip of aperture moderately high (~85%), slightly above mid-whorl, distinctly below shoulder. Aperture attaining 78% of total height. Columellar lip and basal lip reinforced, outer lip moderately thin. Columellar angle 24°. Opercular ridge in outer lip weak. Umbilicus wide (~20%), deep, funnel-shaped with moderately prominent growth lines. Parietal callus long(~58%), slightly thickened, not expanding over base, with weakly concave margin. Anterior lobe of parietal callus subcircular, weakly expanding, relatively narrow. Funicle very weak, moderately narrow, delimited by narrow, concave abapical sulcus, terminating in indistinct, narrow callus fused with anterior lobe. Basal fasciole very prominent, thickened, sharply angled, forming distinct ridge. Color pattern not preserved. Operculum smooth with two marginal ridges, separated by narrower grooves; inner ridge slightly broader (illustrated in Kókay 1966: pl. 7, fig. 12).

Discussion. This is a very characteristic species due to its prominent subsutural shelf, marked shoulder, conical base, funnel-shaped umbilicus and sharply angled basal fasciole. Cochlis baconica ( Kókay, 1966) is superficially reminiscent of the Pliocene Mediterranean Euspira magnesi Pedriali & Robba, 2001 , which differs in its low spire, lower last whorl, ovate aperture, and lacks a funicle ( Pedriali & Robba 2001: pl. 1, figs 1–3; Pedriali & Robba 2009: pl. 1, fig. 20). Cochlis paragigantica nov. sp. might be a closely related species but differs in its much larger size at same growth stage, lacks the broad subsutural shelf, has a narrower umbilicus and weaker basal fasciole.

Paleoenvironment. Shallow marine, inner neritic.

Distribution in Central Paratethys. Badenian (Middle Miocene): Pannonian Basin: Herend ( Hungary)

( Kókay 1966). Styrian Basin: Weitendorf ( Austria) ( hoc opus).
