Baydeni, Binn., and esi)Ocially to S. oralis, Gould, not Say. Comi»arod with the latter, the last whorl is less convex, the aperture is more angular above, the colnmelki less arcuate and more distinctly plicate. The measurements given are of one of the largest specimens. This is the only North American species in which I have noticed the parietal tooth mentioned in the description. Three of my specimens have this tooth; it is lamelliform, about 1""" in length at the base, the iiointed apex having an elevation of about ^"™. (Bland.) Siicciiica Tottciiiana, Lea.
