Diagnosis
ReferenceDiagnosis
J. H. Campbell 1893Shell ovate-oblong, attenuated at the extremities. Spire prominent, showing four whorls; outer lip thickened and having on the inner edge thirteen or fourteen teeth. Anterior half of the aperture wide, but contracted at the extremity, posterior end contracted and projecting slightly beyond the spire. Under the magnifying glass the shell shows strong revolving raised lines and striae.
L. T. Groves 1990Palaeocypraea squyeri (Campbell, 1893) has deeper terminal canals and is more elongate than Palaeocypraea corsicanana, and should be considered a separate species.
