Material.— Sample Rö37: stubs Rö37_2 (one specimen), Rö37_3 (12 specimens), Mount Rettenstein , Northern Calcareous Alps, Austria, Lower Pliensbachian .

Remarks.—In this species we include specimens with a nearly spherical shell, a relatively large number of pores and two stout spines. The length of spines is variable, ranging from one to 1.5 times the diameter of the cortical shell. The specimens can be without nodes on the pore-frame vertices

Fig. 8A) or with strong nodes ( Fig. 8F).

Stratigraphic and geographic range.—Hettangian to Sinemurian ( Carter et al. 1998), Lower Pliensbachian (this study). Haida Gwaii (British Columbia), Italy, Northern Calcareous Alps ( Germany and Austria), Turkey.
