  The mass spectrum of charmed and bottom baryons has been computed on
anisotropic lattices using quenched lattice nonrelativistic QCD. Masses are
extracted by using mass splittings which are more accurate than masses obtained
directly by using the nonrelativistic mass-energy relation. Of particular
interest are the mass splittings between spin-1/2 and spin-3/2 heavy baryons,
and we find that these color hyperfine effects are not suppressed in the baryon
sector although they are known to be suppressed in the meson sector. Results
are compared with those obtained in a previous NRQCD calculation and with those
obtained from a Dirac-Wilson action of the D234 type.
