We study two-body baryonic decays of pseudoscalar {ital B} mesons to charmed-baryon--antibaryon pairs, where baryons (or antibaryons) are orbital ground states in spin doublets or quartets. The four-fermion interaction theory forbids {ital F}-wave decays for spin-quartet--quartet final-state configurations. SU(6) symmetry requires that all decay amplitudes are expressed by no more than eight parameters: three for {ital S} wave, four for {ital P} wave, and one for {ital D} wave. Both {Lambda}{sub {ital c}} inclusive and some exclusive branching ratios are studied based on the assumption of two-body dominance in baryonic decays of {ital B} mesons. Results are listed in tables.
