Original Description

[Original text]: Coquille. – Ovale, operculaire, très-déprimée, fortement carénée et tranchante sur ses bords, qui sont entiers tres-légèrement ponctuée ou perforée, peu convexe en dessus, concave en dessous. Spire à peine convexe, à sommet des plus obtus, composée de deux tours peu distincts, recouverts, sur la moitié de leur largeur, par le retour de la spire. Loges au nombre de six au dernier tour, toutes étroites, très-arquées, lisses, un peu convexes, et très-peu séparées par les sutures; elles sont à leur bord extérieur marquées d’une bordure, et au centre se reunissent autour d’un très-léger disque ombilical. Ouverture sous la saillie ombilicale des dernières loges, et peu visible. Couleur blanc uniforme. Elle s’enroule indifféremment des deux côtes. Elle est très-fragile.

[Google Translated from French]: Shell. – Oval, opercular, very depressed, strongly keeled and sharp on its edges, which are entire, very slightly punctuated or perforated, slightly convex above, concave below. Barely convex spire, with a very obtuse apex, composed of two indistinct towers, covered, over half their width, by the return of the spire. Lodges six in number on the last turn, all narrow, very arched, smooth, slightly convex, and very little separated by the sutures; They are on their outer edge marked with a border, and in the center come together around a very light umbilical disc. Opening under the umbilical projection of the last compartments, and barely visible. Uniform white color. It wraps around both sides indifferently. It is very fragile.

Size:
Diameter, ½ mm.

Extra details from original publication
[Original text]: Cette espèce se rapproche évidemment, par sa grande dépression, de la Rosalina parisiensis (Modèle no. 38), fossile de Paris, et de notre R. depressa, fossile de la craie de Maëstricht; mais elle diffère de la première par son manque de stries inférieures, de la seconde par sa bordure extérieure, de l’une et de l’autre par son disque ombilical. Elle s’enroule indifféremment des deux côtés.

[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.
