We report the first identification of the Eu III lambda 6666.317
line in optical spectra of CP stars. This line is clearly present in the
spectra of HR 4816, 73 Dra, HR 7575, and beta CrB, while it is marginally
present or absent in spectra of the roAp stars alpha Cir, gamma Equ, BI Mic,
33 Lib, and HD 24712.
