Abstract:
    The fifth part of the OGLE-III Catalog of Variable Stars presents 23 R
    CrB (RCB) stars in the Large Magellanic Cloud (LMC). 17 of these
    objects have been spectroscopically confirmed by previous studies,
    while 6 stars are new candidates for RCB variables. We publish the VI
    multi-epoch OGLE photometry for all objects.

Description:
    We use the sample of carbon-rich long-period variables released in the
    previous part of this catalog to select objects with severe drops in
    luminosity, i.e., with the DY-Per-like light curves. DY Per stars are
    often related to R CrB variables. We detect at least 600 candidates
    for DY Per stars, mostly among dust enshrouded giants. We notice that
    our candidate DY Per stars form a continuity with other carbon-rich
    long-period variables, so it seems that DY Per stars do not constitute
    a separate group of variable stars.
