The authors have measured the branching fractions of the Cabibbo-suppressed decays [Lambda][sub c][sup +] --> [Lambda][sup 0]K[sup +] and [Lambda][sub c][sup +] --> [Sigma][sup 0]K[sup +] relative to the Cabibbo-allowed decay modes [Lambda][sub c][sup +] --> [Lambda][sup 0][pi][sup +] and [Lambda][sub c][sup +] --> [Sigma][sup 0][pi][sup +] to be 0.044 [+-] 0.004 (stat.) [+-] 0.002 (syst.) and 0.040 [+-] 0.005 (stat.) [+-] 0.004 (syst.), respectively. They also present the first observation of [Lambda][sub c][sup +] --> [Lambda][sup 0]K[sup +][pi][sup +][pi][sup -] and have measured the branching fraction relative to [Lambda][sub c][sup +] --> [Lambda][sup 0][pi][sup +] to be 0.266 [+-] 0.027 (stat.) [+-] 0.032 (syst.). The upper limit of the branching fraction into the decay [Lambda][sub c][sup +] --> [Sigma][sup 0]K[sup +][pi][sup +][pi][sup -] relative to [Lambda][sub c][sup +] --> [Sigma][sup 0][pi][sup +] has been measured to be
