Seven of the nine are found to be variable and definite periodicity (of 1.2, 2.6 and 6.2 days) is found for three of them, including the classical T Tauri star LkH-alpha 264. Two other members are possibly periodic but each requires confirmation. In addition, a \"field\" star that is associated with the X-ray source RX J0255.9+2005 was discovered to be a variable with a period of 4.2 days.
