I. Introduction This paper is a continuation of two former communications published by the Society, namely, ‘The Bajocian of the Mid-Cotteswolds,’ Quart. Journ. Geol. Soc. vol. li (1895) p. 388, and ‘Deposits of the Bajocian Age in the Northern Cotteswolds: The Cleeve Hill Plateau,’ vol. liii (1897) p. 607. So far as the sequence of the strata themselves was concerned, the results arrived at in these two papers may be best expressed in Table I (p. 127). What the Table indicates is this:—In a north-easterly traverse from Birdlip to Cleeve there are found, at Leckhampton Hill five distinct beds separating two strata which at Birdlip were in juxtaposition; and at Cleeve Hill, three more distinct beds separating two beds which at Leckhampton Hill were in juxtaposition, namely, the Upper Trigonia-grit and the Notgrove Freestone, and another distinct bed separating two other beds similarly placed at Leckhampton—the Snowshill Clay and the Upper Freestone. Consequently where nothing is intervening at Birdlip there are five beds inserted at Leckhampton Hill, and nine beds inserted at Cleeve Hill: that is, with regard to the five at Leckhampton, three additional at the top, and one more at the bottom. The interest which attaches to the exploration of the North Cotteswolds is to ascertain how and in what manner this intervention of strata continues in a farther north-easterly traverse. The results are these:—That the three upper intervening beds at Cleeve Hill—the Phillipsiana-Witchellia-beda—have been planed away, so that Upper Trigonia-grit rests upon Notgrove Freestone; but in the
