Original Description

[d'Orbigny 1826, original text]: Spire surbaissée. Test fixé par la partie non spirale, trochoïde et régulier; ouverture en fente, située à la région ombilicale, et continue d’un loge à l’autre, point de disque ombilical.

[Google Translated from French]: Test fixed by the non-spiral, trochoid and regular part; slit opening, located in the umbilical region, and continuous from one lodge to the other, umbilical disc point.

[d'Orbigny 1826 emend. Brotzen 1948]: Test convex or plano-convex. All whorls visible on the spiral side; umbilical side flat or concave; chambers on the spiral side generally sickle-shaped, extended in length, on the umbilical side they cover each other more or less, the last with a lobate inner margin, periphery mostly radiate; aperture under the lobate margin of the last chamber.

[d'Orbigny 1826]: Synonymy:

Cidarolle? Montfort.

[d'Orbigny 1826 emend. Brotzen 1948]: Remarks: The genotype of the genus Discorbis Lamarck has not been determined for certain. It was very badly figured by Lamarck and the topotypes given by Cushman in his “Foraminifera, their classification and economic use,” 1927, 1933, 1940, are not definitely identical with Lamarck’s figure. Therefore, I consider that the name of the genus Rosalina d’Orbigny must also replace the name Discorbina Parker and Jones. The genus Rosalina is best characterized by the shape of the aperture. The inner suture of the last chamber on the umbilical side is lobate in an anterior and posterior lobe (fig. 19, “lob. ant.” – “lob. post.”). A more or less distinct tenon pushes forward between the lobes (fig. 19, “ten.”). The aperture lies below the posterior lobe and can extend under the tenon. Rosalina is distinguished from Conorbina Brotzen by the umbilical region and aperture, and the plano-convex or convex spiral side.

Synonymy:

Discorbis Lamarck (part) of authors (Cushman, Galloway).
Discorbina Parker and Jones, 1862.
