Discussion / Comments:

Boudagher-Fadel et al. (1997):
Remarks: B. aptiana orientalis has the same shape of test as B. aptiana (Bartenstein) s.s. with a flat to slightly concave dorsal side, six subglobular chambers in the final whorl (with the last chambers being as high as long, h/L = 1 approx.), but it has perforation cones on the early chambers of the last whorl and there is no porticus bordering the aperture.
