Spectral types are given for 31 members and 11 probable nonmembers of the association. The members include four evolved stars (luminosity classes IV and III), one double-lined binary, and three shell stars, all of which are right of the main-sequence band. The remaining three Be stars and one peculiar star fall within the main-sequence band. Key words: associations - peculiar stars - spectral classification
