We report measurements of the branching fractions of the decays Λ+c → Σ+π−π+, Λ+c → Σ0π+π0 and Λ+c → Σ+π0π0 relative to the reference channel Λ+c → pK−π+ . The charmed-strange baryon Ξc(2930)0, decaying to K−Λ+c , is observed for the first time in B− → K−Λ+c Λ−c decays. We also measure B(B− → K−Λ+c Λ−c ) with improved precision, and search for the charmonium-like state Y(4660) and its spin partner, Yη, in the Λ+c Λ−c invariant mass spectrum . Decays of the |0c charmed baryon into hadronic final states were studied. We present the results of a study of excited |c charmed baryons in the decay mode Ξ+c K− .
