PHILYRE´IS(Φιλυρηΐς), an island off the coast of Pontus, in the Euxine. It must have been situated near Cape Zephyrium, opposite the district inhabited by the Philyres, from which, in all probability, it derived its name. (Apollon. 2.1231; comp. Ammian. 22.8; Dionys. Per. 766; Steph. B. s. v. Φίλυρες.) Hamilton ( Researches, 1. p. 261) identifies it with the small rocky island 2 miles west of Cape Zefreh, and between it and the island of Kerasonde Ada.
