Original Description Test planispiral, in the early stages similar to Globigerinella, in the adult becoming somewhat loosely coiled, the earlier coils all visible in side view; chambers globular in the earlier stages, in the adult with lateral prolongations reaching to and slightly over the preceding coil; wall calcareous, perforate; aperture at the base of the last-formed chamber in the median line.- Upper Cretaceous. Extra details from original publication This genus is apparently derived from Globigerinella and differs mainly in the greater amount of uncoiling, and the development of the lateral, radial prolongations of the chambers in the adult coil.
The type species is from the Upper Cretaceous of Western Algeria and there are somewhat similar forms developed in the American Upper Cretaceous.
