  The spectrum of the $c qq$ baryons contains a few states whose nature is not
clearly a three-quark composite and which might have a sizable baryon-meson
component. Examples include the $\Sigma_c(2800)$ or the $\Lambda_c(2940)$. Here
we explore the spectrum of two-body systems composed of a light, octet baryon
and a charmed meson (or antimeson) within a simple contact-range theory in
which the couplings are saturated by light-meson exchanges. This results in the
prediction of a series of composite anticharmed pentaquarks ($\bar{c} q qqq $)
and singly-charmed baryons ($c \bar{q} qqq $). Among the later we find
$J=\tfrac{1}{2}$ $\Xi D$ and $J=\tfrac{3}{2}$ $\Xi D^*$ bound states with
masses matching those of the recently observed $\Omega_c(3185)$ and
$\Omega_c(3327)$ baryons.
