Abstract:
    The eighth part of the OGLE-III Catalog of Variable Stars (OIII-CVS)
    contains type II Cepheids in the Small Magellanic Cloud (SMC). The
    sample consists of 43 objects, including 17 BL Her, 17 W Vir and 9 RV
    Tau stars (first examples ever found in the SMC). Seven stars have
    been classified as peculiar W Vir stars - a recently identified
    subclass of type II Cepheids. These stars have distinctive light
    curves, are brighter and bluer than the ordinary W Vir variables. We
    confirm that a large fraction of the peculiar W Vir stars are members
    of binary systems.
