Spectrophotometry is presented for eleven WR stars. In most cases, previous spectral classifications have been confirmed. From this and previous investigations, it is concluded that the WC 8.5 class should be avoided. All stars in question can readily be classified as WC 9 or, exceptionally, as WC 8. The photometric results, although exposed to large observational uncertainties, permit inclusion of these faint stars into statistical investigations. In two cases, the photometry indicates that the Pop I status of the stars could be questioned. One star, WR 109, is proposed to be a low-mass binary similar to V Sge. For the other star, WR 64, no satisfying interpretation has been found.
