We consider the possibility that muon-number conservation is not a fundamental symmetry of nature. In simple SU(2) xU(1) gauge theories with several scalar boson doublets, muon number will still automatically be conserved by the intermediate-vector-boson interactions, but not by effects of virtual scalar bosons. The branching ratio for ..mu..+e+..gamma.. is estimated to be of order (..cap alpha../..pi..)/sup 3/. Other ..mu..-epsilon transition processes are also discussed.
