Abstract
Accurate positions of the opacity class 6 clouds from the Lynds Catalog of Dark Nebulae have been measured on blue and red prints from the Palomar Observatory Sky Survey (POSS) plates. These revised positions and the dimensions of ellipses fitted to the clouds are listed. The IRAS point source catalog has been searched for sources lying within the boundaries of the 147 clouds in the sample. The distribution and properties of these IRAS sources are discussed briefly.
