1880 Terebellum fusiforme propedistortum de Gregorio , p. 20, pl. V, fig. 17. de Gregorio 1896, p. 38, pl. 3, fig. 6. = Terebellum propedistortum de Gregorio — Jung 1974, p. 38. Pacaud 2008, p. 727. = Paraseraphs propedistortus de Gregorio — Jung 1974, p. 38, pl. 11, figs. 7–17, tf. 28.

Type material. Lectotype — de Gregorio 1880, p. 20, pl. V, fig. 17 ( Jung 1974). The type specimens are presumed destroyed during World War Two ( Jung 1974) Jung (1974) provides dimensions of 41 mm in height and 9 mm in width for material from the type locality.

Type locality. San Giovanni Ilarione , Italy [Lutetian] .

Diagnosis. The shell is slender, with a high, acute apex thinly covered by shell matrix. The labrum is not thickened. The posterior canal is mostly straight, running antispirally towards the apex.

Distribution. EOCENE— Italy Ronca ( de Gregorio 1896). Lutetian— Italy San Giovanni Ilarione ( de Gregorio 1880; Jung 1974); Ronca ( de Gregorio 1896).

Remarks. There is some uncertainty surrounding the type material of Paraseraphs propedistortus , with the collection supposedly destroyed during the Second World War ( Malaroda 1954). Specimens purported from the de Gregorio collection remain unlabelled and are in disarray ( Savazzi 1988a). However, while there appears to be some material that has survived, this does not include the types of Paraseraphs propedistortus ( Jung 1974) .
