We report the results of the search for the pentaquark candidates {theta}(1540) and {xi}(1862) using data from Fermilab experiment E690 in the reaction pp {yields} pX at 800 GeV/c. We find no evidence for narrow baryon resonances near 1862 MeV decaying to {xi}{pi}. Also, we find no evidence of a narrow resonance near 1540 MeV decaying to pK{sub s}{sup 0}.
