Using data collected by the CLEO detector in the Υ(4S) region, we report new measurements of the exclusive decays of B mesons into final states of the type Λc+p̅ n(π), where n=0,1,2,3. We find signals in modes with one, two and three pions and an upper limit for the two-body decay Λc+p̅ . We also make the first measurements of exclusive decays of B mesons to Σcp̅ n(π), where n=0,1,2. We find signals in modes with one and two pions and an upper limit for the two-body decay Σcp̅ . Measurements of these modes shed light on the mechanisms involved in B decays to baryons.
