A 7 Å resolution, 3300-9100 Å spectrophotometric atlas is presented for 20 objects from the Downes & Shara (1993) catalogue of Cataclysmic Variables (CVs). The stars were selected among those listed as lacking published spectra. As for previous papers in this series, the aim is to check the CV status of the objects spectroscopically and to provide absolute spectrophotometry over a wide optical wavelength range. For all programme stars UBVRI magnitudes, continuum fluxes at selected wavelengths and integrated fluxes of emission lines are derived.

Among the 20 programme stars, 10 have a CV-like spectrum, 7 show F-G-K spectra similar to those of field stars, one is a white dwarf of the DA type, one is a sdB and one has just a sharp Htex2html_wrap_inline1515 in emission over a cool continuum.
