Travis,
  I believe that Tom Waller at the Smithsonian synonomized G. pallium and
speciosa.  Tom is a specialist in the Pectinidae so before one dismisses
his conclusion one would do well to read the paper in which he made this
reassignment. I do not have the reference with me but could provide it for
anyone who would like the citation.
