Original Description

The Globigerinae are all of the minute, subglobular, thick-shelled, arctic type, which may be fitly named Gl. Dutertrei, var. borealis.

Extra details from original publication

This form was originally recognised by Brady in material collected by the Austro- Hungarian North-Polar Expedition during the years 1875-1876. He regarded it as a "thick-walled, cold-water, variety"" of Globigerina bulloides d'Orbigny, and in 1882, named it ""variety borealis nov."" However, this proposal was, unfortunately, predated by his subsequently written but earlier published work which appeared in 1881 and the taxon ""borealis"" must date from this year. Subsequently, Brady (1884) considered that G. bulloides vat. borealis was a synonym of Globigerina pachyderma (Ehrenberg), a species which was also recorded from northern latitudes, and which may be seen from Ehrenberg's original illustration (1873, pl. 1, fig. 4) to be tumid and thick walled. We would prefer to retain Brady's name "borealis" for this form since Ehrenberg's illustration does not wholly agree with Brady's species; a re-investigation of Ehrenberg's material is necessary before this problem can be satisfactorily solved.

The lectotype of Globigerina bulloides d'Orbigny var. borealis Brady 1881 (here designated) came from a series of specimens mounted by Brady in a single-slide, labelled ""North-Polar Expedition, 1875-1876; most northern sounding, latitude 83 19' N, depth 72 fathoms,"" and registered in the British Museum (Natural History) as specimens numbers ""1955:10:28: 1008-20."" The lectotype is now registered in the British Museum (Natural History) as number 1959.7.1.1.
