Optical spectroscopy in the range 3300-7800 A is presented for a total of 37 planetary nebulae in the LMC and seven in the SMC. Reddening estimates from Balmer line ratios have been determined, and the line intensities have been dereddened accordingly. Nebular forbidden O III electron temperatures, and where measurable forbidden S II densities, are derived. Forbidden O II electron densities are recalculated using appropriate electron temperatures. Zanstra temperatures are derived for 22 objects possessing detectable stellar continua. These temperatures are in agreement with photoionization modeling of this sample. 35 refs.
