A´MNIAS(Ἄμνιας, Ἄμνειος), a river in Pontus. In the broad plain on the banks of this stream the generals of Mithridates defeated Nicomedes, king of Bithynia, and the ally of the Romans, B.C. 88. (Appian. Mithridat. 100.18; Strab. p. 562.) The plain through which the river flowed is called by Strabo Domanitis. Hamilton ( Researches, &c. vol. 1. p. 362) identifies the Amnias with an affluent of the Halys, now called Costambol Chai, and sometimes Giaour Irmak. It appears that the river is also called Kara Sú.
