We have secured new optical spectra of 11 WR stars in M33 and M31 using the WHT+Faint Object Spectrograph, covering λλ4800–9800å at 14å and λλ3500–5000å at 7å resolution. In our M33 sample five stars are classified as WC4–5 from their C IV λ5800/C III λ5696 line strengths (viz MC 6, MC 53, MC 79, MC 24 and MC 71), one as WC6 (MC 65), one is a WNE-CE star (MC 48) and one is possibly an intermediate WC4-WO star (MC 78). Of the two stars observed in M31, one is classified as WC4–5 (MS 11) and the other as WC7-8 (MS 4).
