Extra details from original publication
Remarks: Globigerinelloides prairiehillensis Pessagno. n. sp. differs, from Globigerinelloides asperus (Ehrenberg) by being larger, showing a more rapid increase in chamber size, and by having a low aperture at the base of its last chamber.
It differs, from Globigerinelloides volutus (White) (= G. messinae Bronnimann) by being much more deeply umbilicate, by having a lowly arched rather than highly arched aperture, and by showing a much more rapid increase in chamber size particularly when seen from peripheral view.
Globigerinelloides prairiehillensis differs from Globigerinelloides multispina (Lalicker) by lacking bipartite apertural apperture by having larger umbilic and in being more evolute.
