Ten new carbon stars with oxygen-rich circumstellar shells have been discovered using IRAS LRS spectral class. The origin of these objects have been briefly discussed. It is likely that they may be a consequence of release of oxygen due to carbon condensation, though other scenarios cannot be ruled out.
