Boudagher-Fadel et al. (1997):
Remarks: B. speetonensis tunisiensis also has
six chambers ventrally, in the last whorl. The last
chambers on the dorsal side are almost as high as
long (h/L = 1 approx.). The aperture has a porticus
throughout its length, broadest posteriorly.
B. speetonensis tunisiensis differs from B. speetonensis
speetonensis in having a more involute dorsal side with more curved intercameral sutures
on the dorsal side and an aperture extending over
the periphery of the penultimate whorl with the
portici of the last three chambers encroaching onto
the dorsal side. |
