We report on a new search for two-body baryonic decays of the B meson. Improved sensitivity compared to previous Belle results is obtained from 414 fb-1 of data that corresponds to 449 million B B-bar pairs, which were taken on the Upsilon(4S) resonance and collected with the Belle detector at the KEKB e+e- collider. No significant signals are observed and we set the 90% confidence level upper limits: Br(B0-> p pbar) <1.1X10-7, Br(B0-> Lambda Lambda-bar) < 3.2X10-7 and Br(B+-> p Lambda-bar) < 3.2X10-7.
