Description:
    We present a catalogue of 233 BL Lacertae objects compiled through an
    extensive bibliographic search updated to mid-1995. A large fraction
    of the sources listed in the catalogue belongs to well-defined samples
    and can be used for statistical purposes. A smaller fraction consists
    of miscellaneous (but confirmed) BL Lacs and of objects classified as
    BL Lac candidates. We discuss the selection criteria of the different
    samples, report the discovery of two previously unnoticed BL Lacs in
    the Palomar-Green survey, and comment on the possible association of
    some of the still unidentified high galactic latitude gamma-ray
    (EGRET, see Thompson et al., =1995ApJS..101..259T) sources with BL
    Lacs. Some statistical properties of the catalogue are also briefly
    discussed.

Note (1):
    a - Derived from the B magnitude assuming B-V = 0.6, the mean value
        for BL Lacs
    b - radio flux at 8.4 GHz
    c - detected only during phase 2 of the EGRET observations and therefore
        not included in the phase 1 EGRET catalogue of Fichtel et al.
        (1994ApJS...94..551F)
    d - from Murphy, Browne & Perley (1993MNRAS.264..298M);
        Perlman et al. (1995b, ApJS, in press) give no redshift,
        so this value might be uncertain
    e - derived from the mean B magnitude using the observed value of B-V
