Query: Where are the Nearby Gas-Rich LSB Galaxies?   The Fisher-Tully `10 Mpc Catalog of Late-Type Galaxies' (FT, 1981) is
remarkably complete. Despite the considerable effort that has been spent
searching for and cataloging low surface brightness (LSB) galaxies, almost no
new HI-rich galaxies have been added to the volume to which the FT observations
were both sensitive (d < 10 (M_{HI}/10^{8.2} Msolar)^{5/12} Mpc) and intended
to be complete (d < 10 Mpc). It has not yet been demonstrated by the new
surveys that HI-rich LSB galaxies are not properly represented in this catalog
of nearby galaxies. Although new optical surveys are discovering heretofore
uncatalogued galaxies at greater distances than the depth of the FT Catalog,
they do not alter the completeness of the FT Catalog for HI-rich LSB objects.
Thus, unless the galaxy population of the local volume is atypical, there is at
present no evidence for a significant, new population of gas-rich galaxies that
has escaped recognition until now.
