B[E] STARS .2. MWC-349-A

We analyse spectroscopic CCD material obtained at the Haute Provence O bservatory. We provide line identifications and equivalent width measu rements in the wavelength region 3700-8790 Angstrom. Over 300 emission features are identified and a comparison of our results with those of other authors is provided, as well as a table of all elements which h ave been identified in the spectrum of the object. The pattern of elem ents present is analogous to that of B-type stars, but some exceptions are noted, such as the absence of C, Al and Mn. We review the present knowledge of the spectrum variability of MWC 349 A. The observations indicate that the equivalent widths of the lines of many elements vary by factors of up to two. We also provide a list of diffuse interstell ar features observed. The latter lead to an average (B - V) excess of about two magnitudes, which is less than what is expected for an objec t having an interstellar extinction of 10-11 magnitudes.
