  The nonleptonic decays of $\Xi_c^0$ and $\Lambda_c^+$ that are dominated by
$W$-exchange are studied. In particular, we anlayse the decay modes $\Xi_c^0
\rightarrow \Xi^{*-} \pi^+, \Sigma^{*+}K^-, \Omega^-K^+$ and
$\Lambda_c^+\rightarrow \Sigma^0\pi^+, \Xi^0 K^+$, $\Xi^0_c\rightarrow
\Sigma^+K^-$.
