Original Description

A single delicate specimen, 0.22 mm. in diameter, exhibiting seven chambers on the inferior side, and two complete whorls of chambers on the upper or rotaline surface. It is clearly allied to the G. cretacea group, but does not agree with either the tvpe or the species sub-cretacea instituted by Chapman for the recent forms of G. cretacea figured by Brady (C. 1901 FFA, p410, pl xxxvi, fig. 16). On the other hand the N.Z. specimen does very closely resemble a little form which has been figured by several authors under the name G. aequilateralis, Brady, disregarding the fact that G. aequilateralis should, as its name suggests, be aequilateral, presenting a similar appearance on both faces.

0.22 mm. in diameter

We have associated our variety with the name of Egger, who is responsible for the original misapplication of the name G. aequilateralis.

Extra details from original publication
These small, compressed rotaline Globigerinae are very rare, but we have observed them before in several tropica! and sub-tropical gatherings.
