Tappan 1987: 481, pl. 525, figs 10–15. Small to medium trochospiral test with 4 globular chambers in the final whorl; chambers spherical to slightly flattened radially. Primary aperture umbilical, a low arch with a thin lip. Bulla of variable configuration may cover sutures on umbilical side. Distribution: Cosmopolitan, equatorial to subpolar latitudes. This species is most abundant in subtropical and temperate sediments ( Bylinskaya et al. 2002), but is quite rare in our material.

2002: 126, pl. I, figs 9–11. Test size variable, trochospiral, well lobulated, with 4 chambers in the final whorl slowly increasing in size. Chambers spherical or slightly ovoid. Aperture umbilical, interiomarginal, a high arch. Wall smoothly perforated. Remarks: The species differs from G. falconensis in having a high aperture without a lip. G. bulloides has a more hispid and thicker wall than does Globigerinella calida . Distribution: A cosmopolitan species, equatorial to subpolar waters. Most abundant in the temperate Atlantic. It is also known for its association with upwelling zones ( Bylinskaya et al. 2002). This species is very rare in our material.
