  We present results for some of the light baryon masses and their excited
states in 2+1 flavour domain wall QCD. We considered several lattice spacings,
with the DBW2 and Iwasaki gauge actions and different sea quark masses on a
volume of $16^3\times32$ and a fifth dimension of size 8. All data were
generated on the QCDOC machines. Despite large residual massses and a limited
number of sea quark mass values with which to perform chiral extrapolations,
our results are in reasonable agreement with experiment and scale within
errors. Finite size effects on most ensembles appear to be small.
