Zusammenfassung:Very deep, blue-and red-sensitive objective-prism plates, taken with the Curtis Schmidt telescope at the Cerro Tololo Inter-American Observatory for various other programs, have been used to survey both Magellanic Clouds for unresolved emission-line objects that can be classified as confirmed or highly probable planetary nebulae. Listed are 102 (22 new) planetaries in the LMC and 28 (3 new) in the SMC. Emission-line stars and compact H ii regions which have been or might be confused with planetary nebulae are also identified. The surface distributions and spectroscopic properties of the planetaries in the two systems are discussed.
