Spectrophotometric observations have been obtained for all 68 planetary nebulae candidates in the Large and Small Magellanic Clouds from the complete sample of Jacoby. While most show line spectra characteristic of planetary nebulae, some 23 of the candidates could not be confirmed or have other explanations. A revised luminosity function is discussed. Many of the emission-line spectra are characterized by very strong forbidden N II and He II lines. One object (SMC 23) showing a peculiar forbidden line spectrum appears to be an extremely dense nebula, yet one may infer that the associated central star is hot and rather massive. Another nebula (LMC 26) shows forbidden lines but not detectable Balmer emission. Radial velocity measurements are discussed for most of the LMC objects, and may be useful diagnostics of the kinematics of the central bar. 30 refs.
