        A search for anomalous Z-Z-gamma and Z-gamma-gamma couplings in        
        the process e+e- -> Z gamma has been performed using data              
        collected with the OPAL detector at LEP2 energies. The study is        
        based on the analysis of the total rate and the properties of the      
        (qbar q gamma) and (nubar nu gamma) final states. Consistency with     
        the Standard Model expectations has been observed, indicating no       
        evidence for anomalous couplings, and 95% CL upper limits have been    
        derived.
