  The couplings and interactions of baryons containing a heavy quark are
related by light quark spin-flavor symmetry in the large $N$ limit. The single
pion coupling constant which determines all heavy quark baryon-pion couplings
is equal to the pion coupling constant for light quark baryons. Light quark
symmetry relations amongst the baryon couplings are violated at order $1/N^2$.
Heavy quark spin-flavor symmetry is used in conjunction with large $N$ light
quark spin-flavor symmetry to determine the couplings of the degenerate
doublets of heavy quark baryons.
