Extra details from original publication
[Google Translated from French]: This species is obviously similar, by its large depression, to Rosalina parisiensis (Model no. 38), fossil from Paris, and to our R. depressa, fossil from the Maastrichtian chalk; but it differs from the first by its lack of lower striations, from the second by its outer border, from both by its umbilical disc. It rolls up indifferently on both sides.
