Notes. WR designations by van der Hucht (2001); nebular classifications by Ma97 (Marston 1997), MC93 (Miller & Chu 1993), Ch91 (Chu 1991), and SB10 (Stock & Barlow 2010). Classifications according to Chu (1981): radiatively excited H ii regions (R), wind-blown bubbles (W), stellar ejecta (E), no ring nebula (− ). Detections by Miller & Chu (1993): ring nebula (RN), probable ring nebula (RN?), possible ring nebula (RN??), no ring nebula (− ). Some stellar designations have been updated with respect to the original works: WR 31a  →  WR 31c; WR 43 is a cluster of WR stars without ring nebula (NGC 3603)  →  WR 42a, WR 42b, WR 42c; WR153  →  WR 153ab.
