The spectroscopy of two carbon-rich mass-loosing variables - R Leporis and DY Persei -is presented. High-resolution echelle spectra of carbon Mira R Lep were observed for two seasons.The heliocentric photospheric radial velocity was found to be +32.6 and +38.4 km/s respectively.Strong emission in atomic resonance lines and C_2 Swan system bandhead at 5165Awas detected,which was apparently the result of dust formation and ejection. The spectroscopical features of theextremely cool R Coronae Borealis star DY Per indicate the presence of surrounding clouds of gasand dust ejected by this star.
