  We calculate mass spectra of charmed baryons within a relativistically
covariant quark model based on the Bethe-Salpeter-equation in instantaneous
approximation. Interactions are given by a linearly rising three-body
confinement potential and a flavor dependent two-body force derived from QCD
instanton effects. This model has already been successfully applied to the
calculation of light flavor baryon spectra and is now extended to heavy
baryons. Within the same framework we compare the results to those obtained
with the more conventional one-gluon-exchange potential.
