A high-statistics study of psi decays into baryon final states has been done with the Mark II detector at SPEAR. A detailed test of baryon-antibaryon decay modes is presented. Substantial resonance formation is observed in multibody decays of the psi involving baryons. Branching ratios for a large number of decay modes are given, including the radiative decay psi..-->..pp-bar..gamma... The flavor-SU(3)-forbidden decays psi..--> sigma../sup + -/(1385)Sigma-bar /sup - +/+charge conjugate are observed with substantial branching ratios.
