> I'm in the frustrating position of being unable to identify an attractive

the

available.
> It is a lightweight, inflated, tan-colored shell resembling Galeodea
rugosa
> from the Mediterranean, but with finer scupture.  But this one is from
deep
> water in the Philippines.  Maybe some kind of Oocorys?  Sculpture
consists of
> fine spiral cords, uniform in size and closely spaced.  Operculum
resembles a
> typical Phalium operculum.  Any suggestions?
