The charm-conserving strangeness-changing two body hadronic decays of charmed baryons are examined in the SU(4) symmetry scheme. In addition to the 20″ Hamiltonian, we consider a 15 piece of the weak Hamiltonian which may arise due to SU(4) breaking or due to some nonconventional dynamics. The numerical estimates for decay widths of some of the modes are presented.
