Identifications of planetary nebulae in NGC 185 (4), NGC 205 (12), and NGC 221 (10 are presented. The nebulae were identified by isolating their STAO III! lambda 5007 and H alpha emission lines. These nebulae will allow a direct determination of chemical abundances in elliptical galaxies in the Local Group. (auth)
