Subspecies Blefuscuiana speetonensis tunisiensis Boudagher-Fadel 1995


Discussion / Comments:
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.
