A revised spectral classification system and a new catalogue for galactic Wolf-Rayet stars

A revised classification system for WoIf-Rayet (WR) stars is presented. Spectrograms of 41 southern stars are reproduced. A search of 436 square degrees along the southern part of the galactic plane yields 13 WR stars not included in Roberts's catalogue. 15 stars in Roberts's catalogue have been found not to be WR stars. The total number known now stands at 127. A new catalogue is given including reliable spectral classification on the new system for 107 stars and photoelectric v-magnitudes, on a system similar to that defined by Westerlund, for I o6 stars.
