Notes

Included in the list of late-type emission-line stars of Allen (1973). These stars may be either symbiotic stars or heavily reddened objects. Classified as Bep in Henize (1976). It might be a pre-main-sequence star or a shell star according to Shore et al. (1990). Lastly, classified as Ge in de Winter et al. (2001).
