A search with the Crystal Box detector shows no evidence for the lepton-family-number-nonconserving decays ..mu -->..e..gamma.., ..mu -->..e..gamma gamma.., or ..mu -->..eee. The search provides upper limits for the branching ratios of GAMMA(..mu -->..e..gamma..)/GAMMA(..mu -->..evv-italic-bar)<4.9 x 10/sup -11/ (90% C.L.), GAMMA(..mu -->..e..gamma gamma..)/GAMMA(..mu -->..evv-italic-bar)<7.2 x 10/sup -11/ (90% C.L.), and GAMMA(..mu -->..eee)/GAMMA(..mu -->..evv-italic-bar)<3.510/sup -11/ (90% C.L.). In addition, a limit for the emission of a light scalar or pseudoscalar boson in radiative muon decay is given.
