Two new O stars have been found in NGC 346, the largest H II region of the Small Magellanic Cloud. One of these has a spectrum of type O3 III(f asterisk), identical to that of HDE 269810 in the Large Magellanic Cloud; it is a major source of ionization in NGC 346. This discovery illustrates the fact that some of the most massive stars in the Magellanic Clouds are not contained in the objective prism and photometric surveys, because they are preferentially located in crowded, nebular regions.
