摘要：
New spectroscopic data of a sample of 10 southern [WC] stars are presented and described. Equivalent widths of carbon line transitions (C II lambda4267, C III lambda5696, and C IV lambdalambda5801, 5812) are used to revise the classification of the seven late-type [WCL] stars of the sample. For them, our spectra allowed us to employ a quantitative system. We have confirmed the previous classification for three of the objects, but for three others, we have encountered different subtypes. Because of the weakness of the oxygen lines, it was not possible to suggest subtypes for the three [WCE] stars.
