Extra details from original publication
This is another species belonging to the group of Globigerina conglomerata Schwager, 1866, Globigerina eggeri Rhumbler 1901, Globigerina eggeriformis McCulloch, 1977, and like G. eggeriformis all were originally labelled as G. conglomerata. On the basis of characters used to differentiate G. eggeri from G. conglomerata the present species is distinct from others in its apertural structure and organization of chambers. The records are almost entirely centered in Galápagos area.
