Original Description

Rosalina. Testa orbiculato-depressa, rugosa, alba, margine bicarinata, umbilicata, umbilico magno; spira subplana, anfractibus tribus distinctis; loculis sex lateraliter compressis, supra subtusque limbatis.
Coquille suborbiculaire, très déprimée, bicarénée sur son pourtour, un peu concave en dessous, fortement ombiliquée, mais sans disque ombilical; la surface en est très rugueuse. Spire à peine saillante, bien marquée par les bordures des loges; composée de trois tours, dont le premier est en partie masqué par des rugosités. Loges comprimées au nombre de six partour, oblongues, aplaties en dessous; obliques, bordées tout autour d'un bourrelet; endessous elles sont plus particulièrement bordées du côté extérieur et ombilical, mais les bourrelets sont moins marqués qu'en dessus. Ouverture sur le bord des loges dans l'ombilic. Couleur blanchâtre uniforme.

Translated from French: "Rosaline. Test as a flat circle, rugose, white, double-keeled profile, with umbilicus, wide; trochospire nearly flat, distinct septa; six laterally compressed chambers, rimmed on spiral and umbilical sides. Size: diameter is 1/4 mm large. Shell is sub-circular, much depressed; periphery is double-keeled, umbilical side is slightly concave, umbilicus is well marked, but without umbilical plate; surface is rugose. Spiral side is slightly raised, well delimited by chamber edges; the test has three whorls, the first one being hidden by rugosities. On the last whorl there are six compressed chambers, oblong, flattened on umbilical side; they are oblique and surrounded by a ridge; on umbilical side, chambers have a rim well marked on external part, but less marked than on spiral side. An aperture opens in umbilical area from internal part of each chamber. Colour is uniformly white. 

This species is distinct from all others by its double-keel profile, by the flattened surface of chambers both spirally and umbilically, by its strong ridges and wide umbilicus; these features are so clear that this species cannot be mistaken with any.

Dimensions: Diamètre 1/4 de millim


Extra details from original publication

Translated using Google Translate original bellow

By its bicarinated back, by the flatness of its chambers above and below, by its strong beadings as well as by its broad umbilicus, this species is distinguished from all the others in a manner thatit cannot be confused with no other.

Par son dos bicaréné, par l'a platissement de ses loges en dessus et en dessous, par ses forts bourrelets ainsi que par son large ombilic, cette espèce se distingue de toutes les autres d'une manière si tranchée qu'elle ne peut être confondue avec aucune

Editors' Notes
Petrizzo et al. (2011) disputed the identification of the neotype identified by Bronnimann & Brown and reassigned it to G. neotricarinata (image is shown on the main database page for G. neotricarinata). Banner & Blow (1960) reached a similar opinion.
