We have observed five new decay modes of the charmed baryon c+ using data collected with the CLEO II detector. Four decay modes, c+pK»0, +, +, and *, are first observations of final states with an meson, while the fifth mode, c+K»0K+, requires the creation of an ss» quark pair. We measure the branching fractions of these modes relative to c+pK-+ to be 0.250.040.04, 0.350.050.06, 0.110.030.02, 0.170.040.03, and 0.120.020.02, respectively.
