A resonance is observed in pK/sup -/..pi../sup +/, anti pK/sup +/..pi../sup -/, pK/sub S//sup 0/ and anti pK/sub S//sup 0/ invariant-mass spectra at 2.285 +- 0.006 GeV/c/sup 2/ which is associated with the lowest-lying charmed baryon (..lambda../sub c/). The Dalitz plot and limits on other modes and on the production of other states are presented. Measurements of inclusive p and ..lambda.. cross sections are also presented and allow an estimate of the branching ratios B(..lambda../sub c//sup +/ ..-->.. pK/sup -/..pi../sup +/) = (2.2 +- 1.0)% and B(..lambda../sub c//sup +/..-->.. p anti K/sup 0/) = (1.1 +- 0.7)%.
