Syntype or holotype illustrated by Michelotti (1847, pl. 17, fig. 17) , Turin Hills, Italy ; the specimen might have been stored in the collections of the Dipartimento di Scienze della Terra , Sapienza Università di Roma , but parts of the Michelotti collection were destroyed during World War II ( Manni 2005 ); early Miocene, Burdigalian. Studied material. 6 spec. NHMW 1976 /1785/0044, Kleinebersdorf ( Austria ) ; 8 spec. NHMW 1976 /1785/ 0 0 47, Kleinebersdorf ( Austria ) ; holotype of Conus raulini , Saint-Jean-de-Marsacq ( France ), SL: 32 mm , MD: 18.5 mm Neuville collection, Université Bordeaux n° 30.2.7. Illustrated material. Figs 5A 1 –A3: Kleinebersdorf ( Austria ): MD: 16.1 mm , NHMW 1976 /1785/0044. Revised description. Small shells with moderately low conical spire; early spire with beaded carina. Late spire whorls smooth, deeply concave near upper suture and with prominent rim at lower suture; suture narrowly incised. Subsutural flexure of medium depth, strongly curved, moderately asymmetrical. Last whorl elongate conical, slightly constricted at base. A few deep and broad spiral grooves are restricted to the base. Siphonal fasciole very weak. Aperture largely destroyed; no information on colour patterns. Shell measurements and ratios. n = 7: largest specimen (fragmented): MD: 16.1 mm , mean SL: 23.9 mm (σ = 1.9), mean MD: 12.7 (σ = 1.0), spire angle: µ = 100.1° (σ = 5.7°), last whorl angle: µ = 33.7° (σ = 1.1°), LW: µ = 1.89 (σ = 0.06), RD: µ = 0.66 (σ = 0.02), PMD: µ = 0.9 (σ = 0.04), RSH: µ = 0.21 (σ = 0.02). Discussion. We do not follow Hall (1966) , who synonymised Conus allioni with Conus brocchii Bronn, 1828 . Conilithes brocchii is a Pliocene species, which differs in its larger size, higher and sometimes slightly coeloconoid spire, prominent sutural ridge and the broader last whorl, lacking the slight constriction of C. allioni , which has a low and sometimes cyrtoconoid spire. Conus raulini Peyrot, 1931 , based on a specimen from the Burdigalian of the Aquitaine Basin, is most probably a subjective junior synonym of Conus allioni . This species was introduced by Michelotti (1847) as Conus Allioni . Therefore , the prevailing use as Conus allionii is an incorrect subsequent spelling. Paleoenvironment. The Kleinebersdorf section represents coastal mudflat environments with Avicennia - mangroves ( Zuschin et al . 2004 ). Distribution in Paratethys. ? Ottnangian (early Miocene): North Alpine Foreland Basin : Bad Tölz ( Germany ) ( Steininger 1973 ); Karpatian (early Miocene): Korneuburg Basin : Kleinebersdorf ( Austria ). Proto-Mediterranean Sea and North eastern Atlantic. Burdigalian (early Miocene): Aquitaine Basin : Saint- Jean-de-Marsacq, Saubrigues ( France ) ( Peyrot 1931 ); Turin Hills: Baldissero, Valle Ceppi ( Italy ) ( Sacco 1893a ; Zunino & Pavia 2009 ). Occurrences from the early and middle Miocene of the North Sea Basin , mentioned by Beyrich (1853) and Kautsky (1925) seem to represent another species (see Janssen 1984 ).
