Spectroscopic identification for 20 cataclysmic variables and related objects

We have observed the spectra of 20 little researched cataclysmic variables (CVs) or objects that have been classified as such. We have identified 13 (65%) as CVs and consider the other 7 as unlikely to be CVs. (Table 1, Col. 8). Using more material than previous authors had, we have identified 1 DA type white dwarf and 4 binary systems, together with the spectral types of the components. Our new data does not support the previous classification of Herbig Ae/Be star for FY Per; rather, it should be a CV. For PG 1712+493 we have isolated the spectra of the central O-type star and the surrounding nebula.
