The properties of pentaquarks containing a heavy antiquark and strange quarks are studied in the bound state picture. In the flavor SU(3) limit, there are many pentaquark states with the same binding energy. When the SU(3) symmetry-breaking effects are included, however, three states become particularly stable due to a ``Gell-Mann--Okubo mechanism.'' They are the Q\ifmmode\else\textasciimacron\fisuud and Q\ifmmode\else\textasciimacron\fisudd states discussed by Lipkin, and a previously unstudied Q\ifmmode\else\textasciimacron\fissud state. These states will have JP=1/2+ and their masses are estimated. These states, if they exist, may be seen in experiments in the near future. \textcopyright 1996 The American Physical Society.
