We present a kinematical study of ring nebulae surrounding Wolf-Rayet stars in the Local Group galaxy M 33, based on Fabry-Perot data obtained at the CFHT. Most of these rings show evidence for multiple phases of mass ejection from the central star. Variations are noted in the [OIII]/Hα emission-line ratios across several ring nebulae generally associated a variation in kinematics. Significant [O III] emission appears to arise from the collision between the fast WR wind and surrounding ejecta from a prior phase, such as a RSG or LBV.
