Material.— Sample Rö37:stub Rö37_6 (five specimens); sample Rö417: stub Rö417 (one specimen), Mount Rettenstein , Northern Calcareous Alps, Austria, Lower Pliensbachian .

Remarks.—Our specimens have a much longer horn than typical Atalantria emmela ( Cordey and Carter, 1996) . Transverse ridges are less raised. These characters are considered as intraspecific variability; Atalanta sp. A of Tekin (2002) is therefore included in the synonymy.

Stratigraphic and geographic range. —Sinemurian to Lower Pliensbachian ( Carter et al. 1998, 2010). Haida Gwaii and coastal Canadian Cordillera (British Columbia, Canada), Baja California Sur, Northern Calcareous Alps ( Austria), Turkey.
