  I review the recent proposal that there are new isotriplet heavy baryons with
masses approximately 2380 MeV and 5760 MeV. This prediction follows from the
application of heavy spin-flavor and light $SU(3)$ symmetries to the observed
charmed and bottom baryon states. It also entails assumptions about the spin
and parity quantum numbers of the observed states which are different than is
commonly supposed. The discovery of such states would imply that the
nonrelativistic constituent quark model is a poor predictor of heavy baryon
spectroscopy. I update the analysis in light of new data which have become
available.
