Abstract
We present spectral types for 175 stars in the ionising cluster of 30 Dorad us derived from multislit observations of 231 stars. Comparison with publis hed classifications for 70 stars in common with other authors reveals excel lent agreement with the exception of a few cases which are discussed in det ail. Our new observations raise to 261 the total number of stars in 30 Dor with known spectral types, outside R136. We analyse the spatial distributio n of these stars according to their spectral types, and find evidence for m ass segregation.
