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 ) .
