We have observed two new decay modes of the charmed baryon Ξ+c into Σ+K-π+ and Σ+K̄*0 using data collected with the CLEO II detector. We also present the first measurement of the branching fraction for the previously observed decay mode Ξ+c → ΛK-π+π+. The branching fractions for these three modes relative to Ξ+c → Ξ-π+π+ are measured to be 1.18 ± 0.26 ± 0.17, 0.92 ± 0.27 ± 0.14, and 0.58 ± 0.16 ± 0.07, respectively.
