A catalog of 2096 galaxies within an area of ≡140 deg2 roughly centered on the Virgo cluster at α ≡ 12h25m and δ ≡ 13° is presented. It should be an essentially complete listing of all certain and possible cluster members, independent of morphological type, down to BT ≡ 18, and it contains in addition many fainter dE and Im members down to BT ≡ 20, as well as all galaxies listed in the Zwicky catalog whether member or background. The catalog is based on 67 blue plates of size 50×50 cm taken between 1979 and 1982 with the du Pont 2.5-m reflector of the Las Campanas Observatory. 1277 of the catalog entries are considered to be members of the Virgo cluster, 574 to be possible members, and 245 to be background (Zwicky) galaxies. For all 2096 galaxies, the catalog gives the coordinates accurate to ⪉10arcsec; the morphological type in the extended Hubble system; the total B magnitude with a mean error of ≡0.1 mag for bright galaxies, and ≡0.5 mag for the faintest ones; and the major-axis diameter measured at an isophotal level of ≡25.5 B/arcsec2. Major-to-minor axis ratios are given for all galaxies brighter than BT = 18, as well as for many fainter ones. Heliocentric velocities are listed for 572 entries.
