Original Description
Shape of test high trochospiral; equatorial periphery distinctly lobate. Wall calcareous, perforate, surface finely pitted, in well-preserved specimens with very minute spines. Chambers spherical, later ones often somewhat ovate, 12 - 15, arranged in about 2.5 whorls; the last whorl of about 4 chambers increasing moderately in size, the ultimate chamber may be smaller than the penultimate one (see fig. 12). Sutures on spiral side radial, deeply incised; on the umbilical side radial, deeply incised. Umbilicus narrow, deep. Primary aperture a high arch, interiomarginal-umbilical; in well-preserved specimens a supplementary sutural aperture is seen between earlier chamber of the last whorl. Coiling random in the Globorotalia palmerae zone; a preference for dextral coiling of over 90% in the Hantkenina aragonensis and Globigerinapsis kugleri zones, Navet formation."

Size: Largest diameter of holotype (fig. 11 a-b) 0.5 mm.

Etymology: The species is named for Mr. G. E. Higgins, senior exploration geologist of The Trinidad Oil Company

Extra details from original publication
Stratigraphic range: Globorotalia palmerae zone to Globigerapsis kugleri zone, Navet formation.

Remarks
: According to the generic definition of Globigerinoides, "Globigerinoides" higginsi, new species, should be included here. This is only done provisionally because no genetic relation is apparent between this lower-middle Eocene form and the main group of Globigerinoides species which appears only at the close of the Oligocene or in the early Miocene. More detailed studies on well preserved material might reveal differences that justify a generic separation of "Globigerinoides" higginsi from Globigerinoides. It has been thought that "Globigerinoides" higginsi might possibly be the ancestor of the Globigerapsis group. However, it differs from Globigerapsis index (Finlay), which is the oldest representative of that genus, in the possession of a large umbilical aperture, higher spire, and more globular chambers.

Through the courtesy of Dr. A. R. Loeblich, U. S. National Museum, an excellently preserved specimen from an Eocene core from the Atlantic Ocean was made available to the author (pi. 36, figs, lla-b). It possesses two sutural supplementary apertures, and the surface is covered with very minute spines. It has been chosen as the holotype.
