MITHRIDA´TIS RE´GIO(ἡ Μιθριδάτου χωρα, Ptol. 5.9.19), a district of Asiatic Sarmatia, E. of the Hippici Montes. It derived its name from Mithridates, king of the Bosporus, whom Vaillant ( Achaemenidarum Imper. vol. 2. p. 246) calls eighth of that name, and who fled to this country for refuge in the reign of the emperor Claudius. (Plin. Nat. 6.5; Tac. Ann. 12.15; Dio Cass.60.8.)
