Original Description
Genus similar to Eouvigerina in size, biserial arrangement of most chambers and spout-like uvigerine aperture, but differing in first and last stages. The early chambers show not the slightest trace, even in the microspheric form, of spiroplectine coiling; the final chambers have no tendency to become irregularly triserial, the whole test being regularly bolivine throughout.

The general similarities to Eouvigerina (especially of the aspera and gracilis type, which have somewhat the same ornament) are so marked that close relationship must surely exist. If so, the elision of the theoretical coiled early chambers and the more settled and compact development throughout is probably due to the later appearance in time of this genus, Eouvigerina proper being an Upper Cretaceous form, while the New Zealand development is Upper Middle Eocene.
