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

Remarks.—This species is characterized by an elongated cortical shell and long polar spines with wide grooves. Ellipsoxiphus suessi ( Dunikowski, 1882) is considered nomen dubium due its poor illustration ( Dunikowski 1882: pl. 5: 50); E. suessi illustrated by Kozur and Mostler (1990) is assigned to Pantanellium skedansense .

Stratigraphic and geographic range.—Hettangian ( Kozur and Mostler 1990), upper Sinemurian ( Pessagno and Blome 1980; Carter et al. 1998), Pliensbachian ( Whalen and Carter 2002; this study). Haida Gwaii (British Columbia, Canada), Baja California Sur, Nadanhada Terrane ( China), Northern Calcareous Alps ( Germany and Austria).
