Wavelength measurements and line identifications in the 3200-3600 A regions are presented for the symbiotic stars AG Dra, HM Sge, V1016 Cyg, V1329 Cyg, Z And, and R Aqr. The O III lines excited via Bowen's mechanism are analyzed in detail, and a shell model yielding reasonable shell thicknesses and electron densities is described. The Ne/Fe ratio is derived for five of the systems, and spectra in the blue region are briefly described. 42 refs.
