DYRAS(Δύρας: Gurgo), a river in Malis, which in the time of Herodotus flowed between the Spercheius and the Melas into the Maliac gulf. At present, the Gurgo(the Dyras) and the Mavranéria(the Melas) unite their streams and fall into the Spercheius. (Hdt. 7.198; Strab. 9. p. 428; Leake, Northern Greece, vol. ii. pp. 11, 26.)
