  The mass spectrum of the positive parity [56,2^+] baryons is studied in the
1/Nc expansion up to and including O(1/Nc) effects with SU(3) symmetry breaking
implemented to first order. A total of eighteen mass relations result, several
of which are tested with the available data. The breaking of spin-flavor
symmetry is dominated by the hyperfine interactions, while spin-orbit effects
are found to be small.
