Naudedrillia Kilburn, 1988

Type species (o.d.) Naudedrillia nealyoungi Kilburn, 1988 .

Remarks: The foregut anatomy of Naudedrillia praetermissa (E.A. Smith, 1904) was described by Kantor et al. (1997: 70).

The operculum of the new species here described differs from that known in other species of Naudedrillia in that the nucleus forms a raised, triangular ‘beak’ externally. The significance of this character is unknown.
