The properties of seven carbon stars which are very likely members of the Large Magellanic Cloud are discussed. Three exhibit enhanced molecular bands of C-13, while one bears a spectroscopic resemblance to the peculiar Galactic carbon star, WZ Cas. The range in bolometric absolute magnitude for the seven stars is found to be from -5.7 to -6.6. By placing the stars in a theoretical H-R diagram, it is concluded that (1) all seven are double-shell burning stars, (2) four of the seven have just recently begun helium shell flashes and, (3) the mass range for the objects observed is from 3 to 9 solar masses.
