Epiklesis
Epiklesis (Lat. invocatio) is the name of a prayer that occurs in all Eastern liturgies (and originally in Western liturgies also) after the words of Institution, in which the celebrant prays that God may send down His Holy Spirit to change this bread and wine into the Body and Blood of His Son. This form has given rise to one of the chief controversies between the Eastern and Western Churches, inasmuch as all Eastern schismatics now believe that the Epiklesis, and not the words of Institution, is the essential form (or at least the essential complement) of the sacrament

With respect to the great Fr. Fortescue, I think that some liturgical scholarship has genuinely moved on since his day.
The notion that the Roman rite actually dropped an explicit epiclesis is more likely to arise from schismatic Eastern polemic against the Catholic Church, than it has any basis in fact.
Far from being "integrists" some of the main scholars in this arena are liturgical ecumenists who would not be seen dead in the traditional camp.
Particularly the Jesuit Robert Taft has done a lot of work on the comparative origins of Eastern and Western rites - I think some of his scholarship could be usefully employed to update Fortescue's history!
