  The results of a recent quenched lattice QCD simulation for charmed baryons
are presented. In contrast to a previous calculation, it is found that
hyperfine splittings are in agreement with quark model expectations and
comparable to experimental values. Preliminary calculations using lattice NRQCD
yield results which are compatible with those obtained using a Dirac-Wilson
action of the D234 type for the charm quark.
