1 Introduction

Several B and A stars in the Bright Star Catalogue (Hoffleit & Jaschek 1982) have been designated as Bn and An stars. The "n'' tag was given by Adams & Joy (1923) meaning the spectroscopic lines are "nebulous'' in contrast to "sharp'' lines seen in other stars. The "nebulous'' nature of the lines presumably results from the fast rotation of the stars, that leads to the large broadening of the lines. Several surveys have been made to search for newly Be stars using different criteria (Irvine 1975; Irvine & Irvine 1979; Irvine 1990; Cote & van Kerwijk 1993 and references therein). It may be seen from both the Bright Star (Hoffleit & Jaschek 1982) and the Be star (Jaschek & Egret 1982) Catalogues that there are many Bn and An stars that have been identified as Be stars. We suspect that the Bn An stars that are listed in the Bright StarCatalogue (Hoffleit & Jaschek 1982), may contain many latent Be and Be-shell stars. During January - February 1997, we have obtained high resolution ($\sim$0.17 Å pixel^-1) and moderate-resolution ($\sim$ 1 Å pixel^-1) spectra of 33 Bn and 49 An stars. The selection of these Bn and An stars was dictated by the accessibility to our telescope and the limit of the spectrograph to obtain good signal-to-noise ratio spectra. Also to compare the spectra of Bn and An stars we obtained the spectra of 17 B and A stars of high rotational velocities ($v\sin i \gt 200$ km s^-1) and another 7 B stars with very low rotational velocities ($v\sin i < 35$ km s^-1), using the same instrumentation that were used for Bn and An stars. Close inspection of the spectra of 82 Bn and An stars (Table 1 presents the list of observed Bn and An stars with HR and HD numbers, spectral types, $V_{\rm mag}$, B-V and $v\sin i$ values) reveals seven new Be stars (Be star designation also includes Oe and Ae stars). Results of spectral analysis of these seven new Be stars are presented here. Section 2 describes the observations and data analysis. Results and discussion are given in Sect. 3. Section 4 presents the conclusion.
