I. Introduction. In a former communication 1 an account was given of the structure of the southern portion of the Malvern Rauge; it is now proposed to supplement this account by a description of the rest of the Malverh Range and of certain portions of the Abberley Range, which were selected with the view of throwing light upon the geological history of the Western Midlands. The structure will be traced from south to north, beginning with Swinyard Hill, which is situated immediately to the north of the area described in the writer's former paper. II. Swinyard Hill. The mlrrow ridge of Swinyard Hill is separated from Midsummer Hill on the south by the Gullet Pass, and from the Herefordshire Beacon by the depression termed by Phillips the ‘Silurian Pass.’ It has been pointed out on a former occasion 2 that the Gullet Pass is traversed by a line of fault. North of this line the width of the Archæean massif suddenly narrows, so that the deposits which flank the hill abut on the south directly against the Archæan mass of Midsummer Hill. The Archzean rocks of Swinyard Hill are well foliated towards the south, and show a marked plaoiocliual disposition. The ridge is flanked on each side by May Hill Sandstone, forming ground with a slope decidedly less steep than that of the ridge itself, especially on the eastern side. The change of slope is usually somewhat sudden, and probably marks lines of faulting on each side; but the May
