Rabbi Hamnuna, the son of Rabbi Yosef, was standing before Rava and said to me, "Bring the tefillin blessings" (Berakhot 24a), and so is the version in the Rif; however, in the Ashkenazi text, the reading is Rabbi Nehemiah, the son of Rabbi Yosef (see there), and in the Shas, they did not correct it.
