   We report redshifts, magnitudes, and morphological classifications for 
5369 galaxies with m_B_ <= 15.5 and for 57 galaxies fainter than this 
limit, in two regions covering a total of 1.70 sr in the southern celestial 
hemisphere. The galaxy catalog is drawn primarily from the list of 
nonstellar objects identified in the Hubble Space Telescope Guide Star 
Catalog (GSC). The galaxies have positions accurate to ~1" and magnitudes 
with an rms scatter of ~0.3 mag. We compute magnitudes (m_SSRS2_) from the 
relation between instrumental GSC magnitudes and the photometry by Lauberts 
& Valentijn. From a comparison with CCD photometry, we find that our system 
is homogeneous across the sky and corresponds to magnitudes measured at the 
isophotal level ~26 mag arcsec^-2^. The precision of the radial velocities 
is ~40 km s^-1^, and the redshift survey is more than 99% complete to the 
m_SSRS2_ = 15.5 mag limit. This sample is in the direction opposite that of 
the CfA2; in combination the two surveys provide an important database for 
studies of the properties of galaxies and their large-scale distribution in 
the nearby universe.

Key words: galaxies: distances and redshifts-galaxies: photometry
