Revised description. Medium-sized moderately slender shells; spire coeloconoid to conical and of variable height. Spire whorls channelled, moderately convex to nearly flat; early spire whorls scalariform, strongly tuberculate and striate (but rarely preserved); later whorls with more or less prominent striae, which may fade out completely on last whorls. Subsutural flexure deep, moderately curved, moderately asymmetrical. Last whorl elongate, slightly ventricose, very weakly constricted with weak spiral grooves on abapical third; shoulder high, more or less prominent, rounded to subangular; position of maximum diameter slightly below shoulder. Siphonal canal short, weakly recurved; siphonal fasciole indistinct. Aperture straight, moderately narrow. Colour pattern under UV light only poorly preserved, consisting of a dense pattern of thin, roughly spirally arranged short dashes and slightly spirally extended dots.
Shell measurements and ratios. n = 20 adult specimens (only large morphs): largest specimen: SL: 58.4 mm, MD: 29.2 mm, mean SL: 51.9 mm (σ = 3.3), mean MD: 27.2 mm (σ = 1.5), spire angle: µ = 98.3° (σ = 10.4°), last whorl angle: µ = 35.1° (σ = 1.9°), LW: µ = 1.91 (σ = 0.1), RD: µ = 0.63 (σ = 0.03), PMD: µ = 0.89 (σ = 0.03), RSH: µ = 0.17 (σ = 0.03).
Discussion. Hall (1966: 137) discussed a close relation of Conus vindobonensis with Conus ventricosus Gmelin, 1791, which would result in a placement in Lautoconus. The tuberculate, depressed scalariform early spire, however, contradicts a relation with Lautoconus. In any case, Hall (1966) was correct to interpret this species as a very polymorphic species comparable to the extant Lautoconus ventricosus. Especially the height of the spire and the convexity of the spire whorls are very variable. Similarly, the outline of the last whorl ranges from slightly ventricose to nearly straight-sided. Like the recent L. ventricosus, the spire of the Miocene C. vindobonensis tends to be more or less gradate in some specimens. Consequently, the high spired, gradate specimens illustrated by Hoernes & Auinger (1879, pl. 6, figs 10–11) as Conus mediterraneus are most probably aberrant specimens of Conilithes vindobonensis. Therefore, Conus mediterraneus var. pupoidemiocenica and permiocenica, which were introduced by Sacco (1893b) as new names for these specimens, are subjective junior synonyms of Conus vindobonensis. The same holds true for the aberrant specimen illustrated by Hörnes (1851, pl. 2, fig. 4) as Conus clavatus, for which Sacco (1893b) introduced the superfluous varietal name mioexclavata, although already Hoernes & Auinger (1879) identified this specimen as their Conus vindobonensis.
Hall (1966: 137) considered this species to be a subjective junior synonym of Conus argillicola Eichwald, 1830, from the Badenian of Ukraine. The specimen illustrated by Eichwald (1852, pl. 9, fig. 2) as C. argillicola differs from C. vindobonensis in its constricted base and the long and reflected siphonal canal. Moreover, the spiral striae on the spire whorls of C. argillicola are much stronger. Therefore, we doubt that both taxa represent the same species. Unfortunately, we were not able to find the type specimen(s) of C. argillicola to solve this question definitely.
Paleoenvironment. Typically found in shallow marine nearshore environments; at Gainfarn, where it is among the most frequent cones, it was associated with seagrass.
