The relationship between the absolute magnitude in the K band and the IRAS color index of (12)-(25) was derived for carbon stars in the solar neighborhood by kinematical analyses of the radial-velocity data and the newly published proper-motion data in the Astrographic Catalogue Reference Stars (ARCS) catalog. The mean absolute magnitude in the K band of carbon stars varies from -0.8 to -8.6 with increases of 0.1 to 0.6 in (21)-(25). This tendency indicates that the more luminous carbon stars have a thicker circumstellar dust shell.
