The true name of the place--that which it bears in the cuneiform inscriptions--was Hupiya; and its site is probably marked by the ruins at Khafaji, near Baghdad, which place is thought to retain, in a corrupted form, the original appellation.

Psittace or Sitace, the town which gave name to the province of Sittacene, was in the near neighborhood of Opis, lying on the same side of the Tigris, but lower down, at least as low as the modern fort of the Zobeid chief.

Its exact site has not been as yet discovered.

Teredon, or Diriaotis, appears to have been first founded by Nebuchadnezzar.

It lay on the coast of the Persian Gulf, a little west of the mouth of the Euphrates, and protected by a quay, or a breakwater, from the high tides that rolled in from the Indian Ocean.
