  Using data recorded by the CLEO-II detector at CESR, we report new
measurements of the branching fractions for the decays of the charmed baryon
$\Lambda_c^+$ into $pK^-\pi^+\pi^0$, $p\bar{K}^0$, $p\bar{K}^0\pi^+\pi^-$, and
$p\bar{K}^0\pi^0$, all measured relative to $pK^-\pi^+$. The relative branching
fractions are $0.67\pm0.04\pm0.11, 0.46\pm0.02\pm0.04,0.52\pm0.04\pm0.05$, and
$0.66\pm0.05\pm0.07$ respectively.
