Type material. Holotype — NMB H15409. The type measures 28.7 mm in length with a maximum width of 7.1 mm ( Jung 1974).

Type locality. Cuise-Lamotte , Oise, France [Ypresian] .

Diagnosis. The shell is smooth and slender, with a protoconch of 11 / 2 to 13 / 4 whorls. The teleoconch has 21 / 2 to 3 whorls. The labial callus is well-developed and the labrum is not thickened. The posterior canal is antispirally bent and does not extend to the apex. The columella is basally bent backward. The labrum does not reach the base of the columella.

Distribution. EOCENE— Italy Ronca ( de Gregorio 1896). Ypresian— France Monampteuil, Aisne ( Caze et al. 2010); Aizy-Jouy, Aisne ( Caze et al. 2010); Saint-Gobain Aisne ( Caze et al. 2010); Sapicourt, Marne ( Caze et al. 2010); Cuise-Lamotte, Oise ( Jung 1974; Caze et al. 2010); Gan, Pyrenees-Atlantiques ( Caze et al. 2010). Italy Roncá ( Jung 1974).

Remarks. A replacement name T. fusiforme Deshayes and T. fusiforme Lamarck of some authors. Despite “ fusiforme ” being widely used, the type is an internal cast of S. sopitus ( Jung 1974) and is included in the synonymy S. sopitus herein.
