Bela Okmyx, or Oxmyx, was an Iotian male who was the boss of the Northside Territory, one of the largest territories on Sigma Iotia II. The spelling "Okmyx" appears in the script for TOS episode: "A Piece of the Action" and on-screen in posters. However, it is pronounced "Oxmyx" throughout and often spelled that in associated sources. "Oxmyx" is given as the local name for Iotia in the ST reference: The Worlds of the Federation. It is unknown why this is so.
