Abstract  X Muscae is amongst the stars listed in the General Catalogue of Variable Stars as "not studied." Visual observations by the author during the 5-year interval 1999 through 2003 indicate this is a large amplitude variable star, probably of the Mira type. A visual magnitude range of 12.2 to fainter than 15.0 is found with a mean cycle of 266 ± 7 days. A preliminary ephemeris for determining maximum brightness is JD 2452085 + 266 ± 7 E days.
