ResumoAn outer shell of nebulosity surrounding Eta Carinae is described. AG Carinae, HD 138403 and Co. D – 46° 11816 are found to be surrounded by nebulous disks or shells with [O III] weak or absent. These three stars all have Harvard classification of P Cygni type and resemble planetaries of low excitation. The spectrum of HD 138403 has some affinity to that of the nebulosity round T Tauri. Diffuse nebulosities near HD 92207 and CPD – 59° 2661 in the neighbourhood of Eta Carinae are also described. A complex field of bright and dark nebulosity at |${11}^\text{h}\,{36}^\text{m}\,-\,{63}^{\circ}\,{07}^{\prime}$| indicates close interaction between stars and nebulosity. The small dark areas are highly irregular in outline and also appear to lie close to stars.
