Holotype — Cossmann 1897 , p. 340, pl. 8, figs. 10, 15. The type measures 73 mm in length and 13 mm in width ( Cossmann 1897 ). Type locality. Bois-Gouët , France [Bartonian] . Diagnosis. The shell is slender with fine spiral lines, with 2.5 protoconch whorls. The labial callus is moderately well-developed. The labrum is not thickened. The posterior canal is moderately antispiral continuing to the apex. The columella is bent backward basally. Distribution. EOCENE— England London Clays ( Tennant 1847 ). Bartonian— France Bois-Gouët, Loire-Atlantique ( Jung 1974 ; Caze et al. 2010 ); Arthon, Loire-Atlantique ( Caze et al. 2010 ); Blaye, Gironde ( Caze et al. 2010 ). Ypresian— Italy northern regions ( Jung 1974 ); San Giovanni Ilarione ( de Gregorio 1880 ). Remarks. This species is recognisable for its long slender shape, which is in contrast to other members of the European Paraseraphs . While similar to P. cantamessae , it differs in geological setting.
