Scientific paper

The Catalogue of Principal Galaxies is described, which lists equatorial coordinates (for the equinoxes 1950 and 2000) and cross-identifications for 73,197 galaxies. The 40,932 coordinates have standard deviations smaller than 10 arcsec. A total of 131,601 names from the 38 most common sources are listed. In addition, mean data for each object are given when available: 49,102 morphological descriptions, 52,954 apparent major and minor axes, 67,116 apparent magnitudes, 20,046 radial velocities and 24,361 position angles. This information was used for facilitating proper identification. Finally, distribution options are explained.
