It differs from G. pseudobulloides in the thinner-walled test, which is smooth to finely hispid, pitted, but never reticulate. It is closely related to Globorotalia compressa. It shows a great variation, and a series of forms has been used in local correlation. The oldest form has been described hy HOFKER (1960, p. 77, fig. I7-20) and BERGGREN (1962, text-fig. I-2). It has not been observed in the Storebrelt-material. This can be due to too sparse sampling.
The form shown in plate I, fig. 3 is common in zone I. It has a relatively high spire, slowly increasing size of chambers, 4-5 per, whorl. The 5-chambered forms seem to be synonymous with G. edita SUBBOTINA. Plate I, fig. 2 shows a form occurring in the upper part of zone I and lower part of zone IV (Zone II-III do not contain G. danica), in zone IV together with the form fig. r. They have very inflated, thin-walled chambers, and are finely hispid.
In the Selandian deposits a form with nearly biconvex test is found.
