    \textit{R. Selten}'s concept of ``perfect equilibrium'' [Int. J. Game Theory 4, 25-55 (1975; Zbl 0312.90072)] is compared with the author's new concept of ``lexicographic undominated'' mixed strategy for non- cooperative games in normal form. It is shown that, in general, perfect equilibria are lexicographically undominated, but the converse is not always true. A local characterization of lexicographically undominated Nash equilibria is also given.
