Abstract:
V(RI)C photometry has been obtained for 262 reddened and very reddened
stars selected from the Stephenson & Sanduleak (1971, Cat. III/43)
catalogue of Luminous Stars in the Southern Milky Way (LSS). This
photometry, together with data from earlier papers in this series, is
used to identify a number of probable variable stars.

Note (1): Stars for which no evidence for variability is found in our photometry
(uvby, BRI, Hbeta) but which have large difference Drilling-SAAO.
Three of the objects are in fields which are crowded and/or
contaminated with strong nebulosity so that misidentification or
"background" effects are more probable than variability.
Note (2): EB : Eclipsing binary
EB? : Probable eclipsing binary
