Rediscovery of the holotype of the Pliocene Cuvierina ludbrooki (Caprotti, 1962), originally described as a scaphopod, has enabled the conclusion that it is specifically distinct from the Late Miocene C. jagti Janssen, 1995, in altogether lacking longitudinal micro-ornament. The relationships of C. astesana (Rang, 1829), C. ludbrooki and C. tubulata Collins, 1934 are studied by means of height/width-ratios. It is concluded that C. astesana and C. ludbrooki are valid species, while C. tubulata is considered to fall within the range of variation of C. astesana.
