REMARKS

This is one of the rare species for which the protoconch is preserved and described by Bandel (2006). This author placed it in Terebralia based on similarities of the protoconch with that of the type species Terebralia palustris , but he also mentioned similarities with the protoconch of Pyrazus Montfort, 1810 . This Eocene species was described by Zittel (1863) from the middle Eocene of Hungary as Cerithium corvinum (Brongniart, 1823) . Although the early spire whorls bear a Terebralia -like sculpture, most of the teleoconch of this large and slender species is smooth and the whorls are flat-sided (Szőts 1953). Moreover, the characters of the aperture are missing, therefore the structure of the canals remains unknown ( Vermeij 2007).
