We report the results of a search for the rare baryonic decay modes B0ΛΛ̅ , B+Λ̅ p, B0Λ̅ pπ-, and B0pp̅ (and their charge conjugate states) using 5.8×106BB̅ pairs collected with the CLEO detector. We see no statistically significant signals in any of these modes and set 90% confidence level upper limits on their branching fractions, B(B0ΛΛ̅ )<3.9×10-6, B(B+Λ̅ p)<2.6×10-6, B(B0Λ̅ pπ-)<1.3×10-5, and B(B0pp̅ )<7.0×10-6.
