  The spectrum of the C=1 hyperons is well described by the constituent quark
model, if the fine structure interaction between the light and strange quarks
is mediated by the $SU(3)_F$ octet of light pseudoscalar mesons, which are the
Goldstone bosons of the hidden approximate chiral symmetry of QCD. With the
addition of a phenomenological flavor exchange interaction of the same form
between the light and the charm quarks to describe the $\Sigma_c-\Sigma_c^*$
and $\Xi_c^s-\Xi_c^*$ splittings, the splittings between the C=1 states fall
within 10-30 MeV of the empirical values. Predictions are presented for the
lowest negative parity excited states and the magnetic moments as well.
  Corresponding predictions for the B=-1 hyperon states are also given.
