Extra details from original publication
Bullae are uncommon features in Gioborotalia, although Morrow (1934, fide Ellis and Messina, 1940 et seq.) illustrated a specimen of Globorotalia cushmani Morrow with a bulla. Loeblich and Tappan (1957) illustrated a specimen of Globorotalia aequa with a bulla, which they regarded as a dwarfed chamber, of no taxonomic significance.
