It is proved that relative to certain normal coordinates any local automorphism of a nonspherical real-analytic hypersurface in $\mathbf C^3$ is a fractional-linear transformation. For a hypersurface in $\mathbf C^n$ a system of normal coordinates is constructed relative to which the entire stability group consists only of fractional-linear transformations.
