Bs, Bc and b-baryons
  We present the latest measurements on masses, lifetimes and branching fractions for the B_s and B_c mesons as well as for b-baryons. For the B_s meson we discuss as well the latest results on mixing. These results were produced by the CDF and D0 experiments at Fermilab or by earlier LEP and PEPII experiments.
