                                 ABSTRACT
 
        The Extreme Ultraviolet Explorer (EUVE) has conducted an all-sky
     survey to locate and identify point sources of emission in four
     extreme ultraviolet wavelength bands centered at approximately 100,
     200, 400, and 600 A.  A companion deep survey of a strip along half
     the ecliptic plane was simultaneously conducted.  In this catalog we
     report the sources found in these surveys using rigorously defined
     criteria uniformly applied to the data set.  These are the first
     surveys to be made in the three longer wavelength bands, and a
     substantial number of sources were detected in these bands.  We
     present a number of statistical diagnostics of the surveys, including
     their source counts, their sensitivities, and their positional error
     distributions.  We provide a separate list of those sources reported
     in the EUVE Bright Source List which did not meet our criteria for
     inclusion in our primary list.  We also provide improved count rate
     and position estimates for a majority of these sources based on the
     improved methodology used in this paper.  In total, this catalog lists
     a total of 410 point sources, for which 372 have plausible optical,
     ultraviolet, or X-ray identifications, which are also listed.
