Basic atmospheric parameters for six RV Tauri variables are considered. The Fe/H abundance ratios for the stars are found to be between -1 and - 1.7, inclusively. Stars of the Preston (1962) type B and C subclasses do not appear segregated by metallicity. In comparison to the cooler Preston type A stars, types B and C are shown to be more metal poor by a factor of 10, on average. The results are consistent with the theory that RV Tau type B and C variables are a direct evolutionary analog to the cluster type II Cepheids. 42 refs.
