HD 213985 is a 9th-magnitude blue star situated at a galactic latitude b = -57°. The authors' measurements of this star in the Geneva photometric system show that it is a large-amplitude, long-term, photometric variable. Visual and UV spectra indicate a supergiant character, and the IRAS data reveal strong dust components around the star. A 220 nm absorption feature of circumstellar origin is observed. It is concluded that HD 213985 is a low-mass object evolving from the AGB to the left of the HR diagram. The remarkable similarity of this star with the enigmatic object HR 4049 makes it likely that the latter is also a low-mass star.
