It is shown that the Regge amplitude a(l,s) has singularities at certain fixed, real, physical values of s for all nonphysical values of l. These singularities are not normal thresholds and are not singularities of the complete amplitude A(s,t,u). They arise indirectly through unitarity. Their presence is deduced from the existence of a perturbation graph that satisfies the Mandelstam representation with spectral boundary curves having asymptotes other than the normal threshold lines.
