This paper is concerned with the space distribution in our own Galaxy of the most luminous stars of spectral types A5 and later which have been classified on the basis of low-dispersion slit spectrograms. Seventy stars of luminosity classes Ia and Iab on the Morgan–Keenan system are considered, of which the majority have been previously noted as of high luminosity at the Yerkes, Harvard, Mount Wilson, and Warner and Swasey Observatories. The Cepheid variables have not been considered.
