In this paper, we discuss the nature of three new carbon © stars discovered in the Digitized First Byurakan Survey (DFBS). The three stars show early-type spectra in the DFBS. To better characterize these objects, medium-resolution CCD spectra were obtained. These stars show spectral features typical to CH-giants
