A new correlation of the Precambrian Torridonian sediments of Rhum and Skye is suggested which equates the Bagh na h-Uamha shale of Rhum with the upper part of the Kinloch formation in Skye and with the Diabaig formation on the mainland. The Rudha na Roinne grit, Loch nan Eala arkose, and Guirdil arkose of Rhum are correlated with the Applecross formation. The occurrence of sedimentary cycles at the base of the Applecross in Rhum and Skye is noted. The strata beneath the Kinloch formation in Skye are not represented either in Rhum or elsewhere on the foreland and do not belong to the Diabaig.
