Abstract We report the results of a search for the rare baryonic decay modes B{sup 0}{r_arrow}{Lambda}{bar {Lambda}}, B{sup +}{r_arrow}{bar {Lambda}}p, B{sup 0}{r_arrow}{bar {Lambda}}p{pi}{sup {minus}}, and B{sup 0}{r_arrow}p{bar p} (and their charge conjugate states) using 5.8{times}10{sup 6} B{bar B} pairs collected with the CLEO detector. We see no statistically significant signals in any of these modes and set 90{percent} confidence level upper limits on their branching fractions, B(B{sup 0}{r_arrow}{Lambda}{bar {Lambda}}){lt}3.9{times}10{sup {minus}6}, B(B{sup +}{r_arrow}{bar {Lambda}}p){lt}2.6{times}10{sup {minus}6}, B(B{sup 0}{r_arrow}{bar {Lambda}}p{pi}{sup {minus}}){lt}1.3{times}10{sup {minus}5}, and B(B{sup 0}{r_arrow}p{bar p}){lt}7.0{times}10{sup {minus}6}. {copyright} {ital 1999} {ital The American Physical Society}
