Original Description regularis, suborbiculata, depressa, subtus convexa, superne late et profunde umbilicata, grosse punctata; anfractus 3, ultimus maximus, conflatus e loculis 5 globosis; aperturae 2-3 in umbilico. Size: Diam. = 0,5 - 0,6 mm. Extra details from original publication Zeichnet sich vor den ubrigen Aden des Österreichischen Tertiärbeckens durch die Regelmässigkeit ihrer spiralen Aufrollung aus und steht in dieser Hinsicht der Gl. cretacea d'O. aus der französischen und böhmischen Kreideformation nahe. Das Gehäuse ist kreisförmig, niedergedruckt, breiter als hoch, im Umfange gerundet, unten mässig convex, oben weit und tief grnabelt, grob punctirt. Drei Umgänge, von denen die ersten sehr kleinen auf dem Centrum des letzten sehr grossen aufsitzen. Dieser bestellt aus 5 in einer Ebene liegenden, kugelig gewölbten, durch tiefe Näthe eingeschnürten Kammern, von denen die letzte besonders gross ist. Die beiden letzten Kammern, mitunter auch die drittlelzte, tragen auf der Ollerfläche im Nahel eine hallwunde Mundung. Ziemlich selten im Tegel von Grinzing bei Wien. Editors' Notes This species was discussed at some length by Bolli 1954 who noted that the holotpye was lost but probably was Tortonian in age. Following this he described a new species, G. ciperoensis for Oligocene forms previously included in the species.
