Radio emission lines of H2O, SiO, HCN, and CO have been searched in the circumstellar envelopes of carbon stars which exhibit the 10 μm silicate feature in the IRAS low-resolution spectra. Water maser emission at 22 GHz has been detected in V778 Cyg. No other emission has been detected in the carbon stars BM Gem, V778 Cyg, and EU And. Two competing interpretations for this curious association of the silicate feature and the water maser with the carbon star, the transient stage hypothesis and the binary one, are examined based upon the present observations. Five other carbon stars and two S stars were also observed for comparison.
