Extra details from original publication
The present species has usually been recorded under the name of Pulvinulina crassa (d'Orb). D'Orbigny's Rotalina crassa (d"orbigny 1840 Mem. Soc. Geol. France, vol. IV, p. 32, pl. III, figs. 7, 8) is from the chalk of Meudon, France, and is very distinct from the recent form, and with very little doubt belongs to another genus, probably Rotalia. His figure represents a species with a rounded, not lobulated margin; the sutures are not depressed, and the last chamber is much larger than the earlier ones, and it has a broad septal face.
Brady has figured two distinct species under the one name of Pulvinulina crassa, on Plate CIII of the 'Challenger' Report. Our examples agree with his figure 12. This form is common off the coast of New South Wales. Both forms have been re-named G. crassula by Cushman and R. E. Stewart (1930, Trans. San Diego Soc. Nat. Hist., vol. VI, no. 2, p. 77, pl. VII, figs. 1a-c), but have taken fig 11 as their type, which we consider to be distinct from Brady's fig. 12."
