The Fermilab Tevatron, operating at s**(1/2) = 1.96 TeV, provides a
rich environment for the study of the bottom and charmed hadrons and for
searches of other bound states. Presented here are recent measurements of
the masses of the following states using fully reconstructed events: B+,
B0, B_s, Lambda_b, and the neutral B**. Lifetimes from both CDF and D0 in
exclusive decays for all of these modes are also presented (sans the B**).
A search was conducted at CDF for the Xi-- and Xi0 pentaquark states in
the decay Xi(1860) --> Xi- pi+/- setting a limit on their production in p -
pbar collisions relative to the number of Xi(1530) baryons seen.
