Species Globigerina collactea Finlay 1939


Diagnosis / Definition:
Bolli (1957):
Coiling random. Largest diameter of figured hypotype 0.35 mm
Discussion / Comments:
Bolli (1957):
Some doubt exists as to the generic position of this species. Finlay (1939) originally described it as a Globorotalia. Because of the umbilical position of the apertures, Bronnimann (1952) removed it to Globigerina. The apertures of the specimens examined are usually umbilical, though a slight shifting of the aperture of the ultimate chamber towards an extraumbilical umbilical position is often noted.
