  Hadron masses are calculated in quenched lattice QCD with a fermion action of
the D234 type on an anisotropic lattice. Hyperfine splittings for singly
charmed baryons are found to be in agreement with expectations from the quark
model and with a magnitude slightly larger than experimental values. Masses of
doubly charmed baryons are also calculated and compared to a variety of model
calculations. Hyperfine splittings in doubly charmed baryons are found to be
slightly smaller than in singly charmed states.
