A List of New Mineral Names. By L. J. SPENCEI~, M.A., F.G.S.

HE following is a list of recently published names, which are not to T he found in the 6th edition (1892) of Dana's ~'ystem of Mi,er,do!ty. Although it can scarcely be hoped to make such a list complete, it may still be useful for reference. Probably not more than a third of these are now minerals, which could, when completely determined, stand as distinct species. Alexandrolito. S.M. Losanitsch, Chem.

Green pebbles from Bagot, Ontario, have been in the British Museum since 1882; these are labelled bagotite, and are identified with the lintonite variety of thomsonite. Molybdenite comes from the same locality. 824 L.J. S~ENCEB
