Original Description Test large, about 0.46-0.55 mm at its maximum diameter, planospiral, early whorls compressed; 8 chambers in the last whorl, slightly inflated, narrow, higher than broad, increasing gradually in size; sutures slightly curved depressed; wall macroperforate with sharp muricae on the early whorls, the macroperforations become deep and the rims of these depressions fuse to give a cancellate texture; aperture interiomarginal, equatorial, symmetrical, extending laterally into a small umbilicus, relict umbilical apertures are seen along the last three chambers of the final whorl; fmal aperture and relict apertures are furnished with thin portici. Size: Etymology: In honour of Prof. F. Banner, University College London, in recognition of his advice and help throughout the researchs, without which the work would not have been accomplished.

Remarks: This species differs from 'B?' bentonensis in having narrower and a higher number of chambers, a muricate test with very concentrated macroperforations. It differs from Alanlordella praebuxtorfi in lacking muricocarina on the periphery of the early whorls, and the much deeper and larger macroperforations. Similar specimens were figured by Ben Haj Ali (1987) consecutively as "Globigerinelloides caseyi" and "Globigerinelloides sp" from the Late Albian of Sfa Bou Bker in Tunisia. In this study, it is found in the Early Albian of Tunisia (Beauvoir III, SS 170). Range: Early to Late Albian. Editors' Notes
