Yes, it is implied in the First Eucharistic prayer. The actual words calling down the Holy Spirit just do not occur there.The epiclesis occurs at the offeratory, before the consecration, in the roman mass. It is not always worded exact, but the invocation of the holy sprit is in every DWS of the church.
This is the issue that many Orthodox have with the Extraordinary Form of the Mass.
