UVBY H-beta photometry of UV-bright stars uvby H-beta photometry is presented for 90 stars taken from an earlyversion of the Carnochan and Wilson (1983) catalogue of stars that havevery negative UV colors. Two have definite UV excesses (HD 36629, and HD81307). Four early-B stars have UV colors too positive for their visibleclassification, and beta-indices that indicate higher luminosities thanappear possible on galactic distribution grounds. Six late-B starsappear to have discordant flux distributions for which there are noobvious explanations. It is suggested that the high population ofsubluminous stars derived by Carnochan and Wilson is the product of thestatistical treatment used and the extreme patchiness in theinterstellar absorption, which gives rise to large numbers oflittle-reddened stars.
