Because of a computational error, the power-law slope of the cluster luminosity function in the nuclear ring was incorrectly presented as having a value a=2.10+/-0.04. The correct value is a=3.7+/-0.1, which is not similar to other young cluster systems. This steep slope is interesting and could be interpreted in a number of ways; in particular, it suggests that many of the sources in the nuclear ring could be extreme supergiants, rather than clusters. However, as noted by D. Maoz, A. J. Barth, L. C. Ho, A. Sternberg, & A. V. Filippenko (Astron. J. 120, 1289 (2000)), individual blue supergiants that have absolute visual magnitudes up to -10 are very short-lived and may only explain a handful of the point sources seen in other nuclear rings. We cannot rule out the possibility that more of the sources in the nuclear ring of NGC 1326 than we originally thought are actually single stars, because at the distance of 19 Mpc, very compact clusters are hard to distinguish from stars. On the other hand, the analysis of two-color plots and reddening-free parameters favors the interpretations given in the paper, implying that the luminosity function is more deficient than usual in high-luminosity clusters, at least in this case. This issue will be discussed in a separate paper on the sources detected in the inner ring of NGC 3081, which presents a similar situation (R. Buta, G. G. Byrd, & T. Freeman 2001, in preparation). R. B. would like to thank B. G. Elmegreen for helpful discussions.
