Abstract
A complete list is given of all lines observed between 5000 and 6650 Å in the spectrum of a^2 CVn. Approximately three-quarters of the features have been identified. Lines of Pb ii and P ii are not present. Lines of Gd m and Pr m vary in equivalent width and radial velocity in a manner similar to the singly ionized rare earths. Lines of Cl ii are present and also behave like those of a rare earth.
