We discuss possible deviations from QED produced by a virtual excitedspin-3/2 lepton in the reaction $e^+e^- \longrightarrow 2\gamma$. Data recordedby the OPAL Collaboration at a c.m. energy $\sqrt{s} = 183 GeV$ are used toestablish bounds on the nonstandard-lepton mass and coupling strengths.Comment: Latex, 5 pages, 7 ps figures. To be published in Phys. Rev.
