Extra details from original publication

The above recent Species has hitherto been referred to the Cretaceous type of G. cretacea. There is, however, no reason for retaining that name for the recent specimens, for they differ essentially from the typical Chalk Globigerinae. The recent specimens have a thick structured shell-wall; the chambered whorls of the test are few, and the spire is depressed or even excavate.

Brady remarks (Rep. Chall. 1884, vol. ix. p. 597.), concerning these recent forms: "I have never met with recent specimens, either amongst surface-organisms, or in bottom-ooze .. which presented exactly the same characters as the typical Cretaceous variety; though shells similar in general conformation, and more nearly related to Globigerina cretacea than to any other recognized modification of the genus, are not uncommon in certain localities.''

This species, in common with others of the same genus, increases in frequency in the deeper dredgings taken round Funafuti.

Editors' Notes
Junior homonym of G. subcretacea Lomnicki 1901. Rögl & Bolli 1973 regarded this as a discrete form and proposed a new name for it: Neogloboquadrina dutertrei blowi Rögl & Bolli 1973
