We discuss heavy-lepton pair production via the reaction ..gamma.. + Z ..-->.. L/sup +/ + L/sup -/ + Z followed by the decays L/sup plus-or-minus/ ..-->.. ..mu../sup plus-or-minus/ + ..nu.. + nu-bar or L/sup plus-or-minus/ ..-->.. e/sup plus-or-minus/ + ..nu.. + nu-bar. Particular attention is given to the energy and angular distributions of the final detected leptons. The only reasonable signal for heavy-lepton production seems to be the detection of ..mu..e pairs in relatively quiet events. In the case of ..mu mu.. pairs the signal from the decay of the heavy-lepton pairs is much smaller than the background due to regular Bethe-Heitler production for both the cross section and for all the differential spectra.
