Presented here are spectra and data on five probable diffuse bands with central wavelengths near 4180, 4070, 4040, 4000, and 3980 A which have full-width-half-maxima lying in the range 10-30 A. No narrow unidentified diffuse bands were found, but atomic and diatomic molecular absorptions, including CH and CH+, were readily detected along some lines of sight. Although broad diffuse bands have now been found at longer wavelengths that appeared at one time to be the case (Herbig and Leka, 1991), it is clear that there are no prominent narrow bands at the shorter wavelength end of the diffuse band spectrum. This high-resolution spectra was reported for a number of reddened O- and B-typed and comparison stars, recorded with the 88 inch University of Hawaii telesecope in June of 1993. The sample included the heavily reddened star HD 183143.
