Abstract
LONDON. Geological Society, November 4.—Dr. A. Smith Woodward, president, in the chair.—L. Richardson: The inferior oolite and contiguous deposits of the Doulting-Milborne-Port District (Somerset). This. paper embraces the country around Bruton, Castle Cary, and Blackford. In the northern half of the Doulting Milborne Port district the bulk of the yellow Upper Lias Sands is of disansi hemera; but in the neighbourhood of Cole and Castle Cary the topmost portion is of dumortieriae hemera. In the south-eastern portion, under Stowell, while the main mass is probably of moorei dumortieriae hemeræ, the upper 50 ft. is of aalensis moorei date. Rock of garantianae hemera spreads over the whole district. From Doult ing to Bruton the Garantiana beds rest directly on the Sands. In the neighbourhood of Cole there is a synclinal area, and beds of blagdeni, sauzei, witchel liae, shirbuirniae, discitae, and murchisonae hemeræ are seen between the Garantiana beds and the Sands. At Corton Downs are rocks of sauzei, witchelliae, shirbuirniae, discitae, bradfordensis, and murchisonac hemerie. In this southern portion of the district it is difficult to determine the upper and lower limits of the deposits of discitae, shirbuirniae, and witchelliae hemeræ. The rock of garantianae hemera varies much from place to place in thickness and lithic structure. Above the Garantiana beds come the Douling Stone, Anabacia Limestones, and Rubbly beds. The Anabacia Limestones soon lose their lithic char acters; but the Doulting Stone spreads over the Oolitic tract, and is exposed in numerous quarries. In the southern portion of the district, the lower portion of the equivalent of the Had spen Stone passes into the Sherborne Building Stone, and the top portion, plus higher beds, into the Rubbly Limestone beds, such as those displayed in quarries in the eastern portion of the Sherborne district.—E. T. Paris and L. Richardson: Some Inferior Oolite pectens. Descriptions and illustrations are given of one new species of Camptonectes, of two new varieties of Chlamys articulata (auctt.), and of two new species of Velopecten.
