Using an InSb photometer/spectrophotometer attached to the 1-m ESO telescope (La Silla, Chile), we searched for the near-infrared emission from the Sharpless regions S269, S271, S307, and S311. These regions appear on the Palomar Sky Survey red plates, as bright visible nebulae, and have extended radio continuum emission.
