Extract

The specimen to be described was disinterred by the writer in a small and practically disused Chalk pit on the east side of the road leading from Sulham village (Berkshire) in a S.S.E. direction towards Theale, and 530 yards distant from the former. The place of burial was in the undisturbed face of the pit at about 5 feet above the road level of 190 feet above sea-level. The exposure is recorded on the 6 inch map sheet XXXVI surveyed by J. H. Blake in 1895. The Chalk in which the pit occurs is coloured as “Upper”, but the precise zone is not indicated either on the map or in the memoir (1).
