Title: Where are the missing members of the baryon antidecuplet?
Abstract: We analyze the consequences of the observation of exotic pentaquark baryons on the location of the nonexotic baryons belonging to the antidecuplet. We suggest that there must be a new nucleon state at 1650--1690 MeV and a new $\ensuremath{\Sigma}$ baryon at 1760--1810 MeV.
