Extra details from original publication
Remarks: The openings along the sutures are not always discernible due to the masking effect of adhering matrix. Additional larger openings pierce the wall of the globular chamber, and although scattered they appear to be limited within a certain area. The dimensions of the tests and the sizes-of the openings vary considerably and it may be possible that the perforations in general can be used as a morphologic criterion (Hofker, 1950, pp. 16-17). The Globigerina stage is somewhat concealed in thick shelled individuals because the additional thin layers also cover the initial portion of the test. The initial chamber is very rarely visible, and the number of Globigerina chambers cannot be exactly established.
