Original Description "Espèce à cinq loges." Extra details from original publication Synonym - Globigerina fragilis d'Orbigny, 1826, Ann. Sci. Nat., p. 111 [277] [nom. nud.].
[Fornasini, 1903 p. 141]: La Gl. fragilis, citata di nuovo ventisei anni più tardi dall'autore stesso come 'espèce à cinq loges' (Prodrome, vol.III, 1852, pag.157, num.2924), ha realmente cinque camere nell'ultimo giro, e per questo e per altri caratteri differisce ben poco da la varietà concinna de la Gl. bulloides (Mem. r. Acc. Sc. Bologna, s.5a, vol. VII, 1899, pag. 578, tav. I, fig. 6-9; tav. II, fig. 2). D'altra parte, un certo grado di generale depressione e una maggiore regolarità de la spira l'avvicinano notevolmente a la Gl. cretacea; ma è altresì evidente l'affinità di quest'ultima con la var. concinna.
