Jung 1974 , p. 31 . Type material. Neotype — MNHN A28935, was selected by Caze et al. (2010) to bring taxonomic clarity, given the lectotype designated by Jung (1974) from the Bernay Collection cannot be found. The missing Jung type measured 13.4 mm in length and a width of 7 mm ( Jung 1974 ). Type locality. Chaussy , France [Lutetian] . Diagnosis. The shell has a large apical angle and an inflated body whorl. The greatest diameter of the shell is just above the middle. The labial callus is thin, and the labrum is sinuous and thickened adapically. The labrum is abapically prosocyrt and adapically opisthocyrt. The columella is bent backward at the base and reaches down nearly to the base of the labrum. The siphonal notch is moderately developed. The shell is smooth with only a few faint spiral lines near the base. Distribution. EOCENE—Lutetian/Bartonian— France Ferme de l’Orme, Paris Basin ( Jung 1974 ); Grignon, Paris Basin ( Jung 1974 ). Italy Palermo ( Jung 1974 ); San Giovanni Ilarione ( de Gregorio 1880 ).

Ypresian— Hungary ( Szöts 1953 ). Remarks. The two recognised members of Miniseraphs can be readily differentiated by size and shape, with M. isabella ( Deshayes, 1865 ) larger and slenderer than M. eratoides Cossmann, 1889 .
