Mustered out of service.
--The Maryland Zouaves, Capt. Wm. H. Waters, formerly belonging to the 47th Virginia regiment, but lately attached to the 2d Arkansas battalion, who fought gallantly in the recent actions near the Chickahominy, having served out their terms of enlistment, were mustered out of service yesterday. They forfeit, we believe, part of the regiment which was to have been commanded by Col. Zarvona, of Maryland. A majority of the company will proceed directly to join the advance forces of General Stonewall Jackson
