BERIS or BIRES(Βῆρις, Βίρης), a river of Pontus, which Arrian places 60 stadia from the Thoaris. Hamilton ( Researches, &c. vol. 1. p. 280) identifies it with the Melitsch Chai, a deep and sluggish river,between Uniehand the Thermodon. He found it to be six miles, or 60 stadia, from the Thuréh Irmak, which he seems to identify correctly with the Thoaris.
