It appears that there are two resonances with ${J}^{P}=1/{2}^{\ensuremath{-}}$ quantum numbers in the energy region near the $\mathrm{\ensuremath{\Lambda}}(1405)$ hyperon. The nature of these states is a topic of current debate. To provide further insight we use Regge phenomenology to access how these two resonances fit the established hyperon spectrum. We find that only one of these resonances is compatible with a three-quark state.
