Diagnosis / Definition: |
Banner & Desai (1988):
This subspecies differs from B. globigerinelloides (Globigerina glohigerinelloides Subbotina, 1949) in possessing chambers which, in the final whorl, become as high as long, with more deeply indented intercameral sutures and a more lobulate periphery. On the spiral side, the chambers of early whorls are globular to reniform, but as the later chambers become higher, they occupy 38-40% of the total test diameter (as compared to 30% in the typical form of the species). |
