Original Description
Test free, subglobular; early portion trochospiral with subglobular chambers, final chamber embracing and covering the umbilical region of the early coil; sutures depressed, radial to curved; wall calcareous, perforate, radial in structure, surface smooth to hispid or spinose, the spines broken from the later chambers dtiring preservation, but remaining visible on the earher chambers when unfilled specimens are dissected; primary aperture interiomarginal, umbilical in the young stage, covered in the adult by an enveloping final chamber, with two or more arched secondary apertures at the lower margin of the final chamber, at the contact with the sutures of the earher whorl.

Etymology: Globus, L., a globe or ball + gero, L., to bear or carry + apsis, L., arch; gender, feminine.

Extra details from original publication
Remarks: Globigerapsis, new genus, differs from Globigerinatheka Bronnimann in lacking the small angular bullae covering the secondary apertures. It differs from Globigerinoides Cushman in the absence of an umbUical primary aperture in the adult. Globigerapsis does not show the multiple apertures on earlier chambers as does Globigerinoides and Porticulasphaera, new genus.

Bronnimann (1952a, p. 27, text-fig. 3d-f) included a single specimen of Globigerapsis kugleri with his Globigerinatheka barri, considering it to represent a stage prior to the development of the sutural bullae. Although the two genera may be closely related, they have different geologic ranges, the present genus beginning earlier.

Globigerinoides semiinvoluta Keijzer also belongs to the present genus and a hypotype (USNM P3937) from the Eocene Navet formation. Hospital Hill marl, Globigerapsis semiinvoluta zone type locality, San Fernando, Trinidad, B. W. I., is here figured for comparison.

Bermudez (1949), p. 279, pl. 21, fig. 44) described as Globigerina mexicana Cushman a specimen which actually belongs to the present genus, and seems closer to the species Globigerapsis semiinvoluta (Keijzer), although it is perhaps a distinct species.
