If my memory doesn't fail me or there is literature of which I am not
aware, this should be Geophorus acutissimus (Sowerby, 1841).  Tom, if
someone has placed Geophorus into the synonomy of Sulfurina, please let me
know.  And if someone actually did this, a strong letter will
follow.....The operculum, shell shape, and embryonic whorl sculpture are
completely different in the two taxa...
