It is demonstrated that axisymmetric models with f=f(E,L_z) cannot simultaneously fit the observed surface photometry and kinematical data on NGC 720. Axisymmetric models in which the velocity ellipsoid aligns with cylindrical coordinate axes and which have [v_phi^2] = [v_R^2] do provide an acceptable fit.
