Abstract:
    We present the coordinates, apparent magnitudes, and morphological
    types for 230 galaxies presumably identified with HIPASS (HI Parkes
    All-Sky Survey) sources. The new optical counterparts of the HIPASS
    sources follow the well-known statistical relationships between the
    hydrogen mass, luminosity, and type of galaxies.
    Low-surface-brightness galaxies constitute a significant fraction
    among these objects. The median value of the hydrogen
    mass-to-luminosity ratio for them is a factor of 2 or 3 higher than
    that for bright HIPASS galaxies, reaching 1.7M☉/L☉. A
    number of our objects are located near the boundary log
    (M(HI)/L(B))=0.2(M(B)+20) that defines the zone of gravitational
    stability of disk galaxies against large-scale star formation.
