On the basis of spectroscopic CCD material obtained at the Haute Prove
nce Observatory, we pros ide line identifications and equivalent width
measurements in the wavelength region 4100 - 8900 Angstrom of the spe
ctrum of MWC 297. About two hundred features are identified, almost ex
clusively emission lines. Only one interstellar feature could be ident
ified (lambda 6613) a fact which contrasts with the eigth magnitudes o
f extinction found by photometrists. The spectrum of the underlying st
ar corresponds probably to a late O or early B-type object. The cooler
emission lines correspond to a spectrum of a middle A-type star. Anal
ogies with other stars observed in this series of papers are examined.
