BAPHYRAS or BA´PHYRUS(Βαφύρας), a small river of Macedonia, flowing by Dium through marshes into the sea. It was celebrated for the excellence of its τευθίδες, or cuttle-fish. (Liv. 44.6; Athen. 7. 326d.; Lycophr. 274.) Pausanias (Paus. 9.30.8) relates that this was the same river as the Helicon, which, after flowing 75 stadia above ground, has then a subterraneous course of 22 stadia, and on its reappearance is navigable under the name of Baphyras. (Leake, Northern Greece, vol. 3. p. 411.)
