The Family Pyramidellidae (Mollesca) from Northern Australia

Abstract

This paper reviews for the first time the family Pyramidellidae from northern Australia. The area includes the Solanderian zoogeographical province, and part of the Dampierian province. All species, whether previously described or now proposed as new, are figured and discussed. The division of the family into three new subfamilies is also proposed. In all 150 species or probable species belonging to 40 genera are reviewed. Of the genera 15 are proposed as new, and of the species 90 are proposed as new, and seven are left specifically unnamed pending the acquisition of more material. A key to the subfamilies and Australian genera is provided.
