The chiral Ward identities for the pseudoscalar nonet including the glueball candidate iota(1450), together with the requirement that the topological susceptibility be positive, imply that GAMMA(iota..--> gamma gamma..) is typically small (<1 keV), in agreement with recent experimental values. The topological susceptibility is, as expected, much smaller than pure-gauge-field estimates.
