    It is proved that if a symmetric Finsler space remains to be symmetric under a non-trivial \({\mathcal Z}\)-transform [as defined in \textit{M. Fukui} and \textit{T. Yamada}, Tensor, New Ser. 35, 216-222 (1981; Zbl 0465.53017)], then the space is of zero-curvature. Further, \({\mathcal W}\)-recurrent and \({\mathcal D}\)-recurrent Finsler spaces under projective changes are studied.
