district,where between them and the Fullers-Earth Bock occurs a veryfossiiiferous band crowded with Ostrea and Rliynchonella, whichMr. Richardson designates * the MliynchoneTla-concinna Bed. Asimilar bed occurs above the Neseran Beds round Chipping Norton,and at Ardley; in the Calvert Boring it rests almost directly onChipping-Norton Limestone, and at Stonesfield on the StonesfieldSlates. The Fullers-Earth Bock, both of Somerset and of the Cottes-wolds, is characterized by Teloceras subcontractum, as are theWeatherstones and Shell Beds of Minchinhampton, and appears to■come into line with Bed 31 at Ardiey (L. Richardson, in litt.). The whole group described as Upper Fullonian (Upper Beds offig. 5, p. 509) can be paralleled with the Great Oolite Clay and■Great Oolite Limestone resting on the Upper Estuarine Series north•of Peterborough, where, however, lihj/nchonellce are practicallyabsent, although they are abundant in the same beds at Oundle. qsEaquaoo ^2 rO •16 1^ I ■ch 5
