Spectra of 37 Galactic WR stars were observed and reduced in the spectral range 790--895 nm. The main spectral features are identified and the equivalent widths and FWHMs of the strongest emission lines are measured. The equivalent width of the diffuse interstellar band at 862 nm is also measured and the new estimates of color excesses E(B-V) are derived by using an empirical relationship between the equivalent width and the color excess. The equivalent width ratios for the lines C III 850 nm, C IV 886 nm and C II 880 nm were found to correlate well with the WC subtype.
