The production of strange baryons ..sigma../sup +- / (1385) and ..gamma../sup -/ has been observed in e/sup +/e/sup -/ annihilations at 29 GeV center-of-mass energy, by use of data obtained with the High Resolution Spectrometer at the SLAC storage ring PEP. The total mean multiplicities are measured to be = 0.033 +- 0.006 +- 0.005 and = 0.016 +- 0.004 +- 0.004 per hadronic event. The results are in good agreement with the Lund string model.
