The Curtis Schmidt telescope was used to survey both the Large and Small Magellanic Clouds in the lines of forbidden O III at 5007 A, H-alpha + forbidden N II, and forbidden S II at 6716 and 6731 A, with the purpose of studying the ionization and excitation conditions of the shell nebulae in the Clouds. In the LMC, a number of shell nebulae have images that appear disk-like in forbidden O III; often the disk is concentrated toward what presumably are central stars. This is uncharacteristic of SNRs, and these objects are most likely H II regions. A few of the nebulae have significant forbidden S II strengths, sharp edges, and no obvious possibilities for exciting stars; these are very good candidates for possible identification as SNRs. The SMC is generally lacking in the regions strong in forbidden O III and S II. However, S131 has exceptionally strong S II.
