 Notes\\
1: Identified as a star with very strong H$\alpha$ emission by
Merrill \& Burwell~(\cite{merrill50}).\\
2: Wolf-Rayet star, infrared spectral type WC8; see Pasquali et~al.~(\cite{pasquali02}). It had been previously recognized as an emission-line star by Melikian \& Shevchenko~(\cite{melikian90}).\\
3: Already recognized as an emission line star by Dolidze~(\cite{dolidze75}) (star 20--091).\\
4: In the W75N star forming region, strong excess at 8~$\mu$m (Davis
et~al.~\cite{davis07}).\\
5: Suspected Herbig Ae/Be star basedon its infrared excess.\\
6: Double star, separation 1"1: type estimated as G3IV-V by Straizys et~al.~(\cite{straizys89}) based on Vilnius photometry.\\
7: Identified as a star with weak H$\alpha$ emission by Merrill \& Burwell~(\cite{merrill50}).\\
8: In DR~6.\\
9: Identified as a star with strong H$\alpha$ emission by Merrill \& Burwell~(\cite{merrill50}).\\
10: In the HII region \object{DR~21}.\\
11: Possibly associated to \object{IRAS~20288+3934}.\\
12: Already recognized as an emission line star by Dolidze~(\cite{dolidze75}) (star~20--089). In the HII region \object{DR~5}.\\
13: In DR~21.\\
