    Let D be a bounded domain in \({\mathbb{C}}^ n\). The point \(z^ 0\in \partial D\) is called good (in the sence of Greene and Krantz) if there exist a point \(k^ 0\in D\) and a sequence \(\{\phi_{\nu}\}\in Aut(D)\) such that \(\lim_{\nu \to \infty}\phi_{\nu}(k^ 0)=z^ 0\). Let, further, \(E(p_ 1,...,p_ n)\) denote the domain \(\{(z_ 1,...,z_ n):\) \(| z_ 1|^{2p_ 1}+...+| z_ n|^{2p_ n}<1\}\), where \(p_ 1,...,p_ n\) are positive integers. The author proves a result which gives the characterization of certain domains having only good boundary points. In particular, let D be any bounded domain and let \(p_ 1,...,p_ n\) be arbitrary integers, \(p_ i\geq 2\). If \(\partial D\) coincides with \(\partial E(p_ 1,...,p_ n)\) near a point \(z_ 0\in \partial D\) then \(z_ 0\) is not a good point.
