Neutral hydrogen spectra are presented for 53 faint dwarf galaxies in Virgo, completing the Arecibo survey of all late-type dwarfs in the Virgo Cluster Catalog, and for 42 dwarf galaxies from the field sample of Binggeli et al. (1989). For detected galaxies, heliocentric velocities, profile widths, and single-beam fluxes are tabulated. The field sample has been used to investigate the field luminosity function and the clustering of dwarf galaxies vis-a-vis bright galaxies. 31 refs.
