" Such field evidence as I saw would seem To me to indicate that the fossils of the cyl. are probably all of about the same age, and not much older than the matrix." Adams Pottine, St. Allans. Shales above cyl. Just above the cyl. occurs a zone of white quartzite, fine grained, that has remains of very small strolites (3/16 inch acorn, and round) and Linnarsonia like the ones just north of the Chichester one mile N.W. of Highgate Centre. It also has numerous fragments of trilobites. This quartzite has considerable jellastic white mica, and has none of the wind blown sand seen so much in the giant cyl. Higher occur the dark blue micaceous rim-stained marl like limy shales. Some beds are an impure li. It has the Agnostus cretoides type, Ptychoparia, very rare Linpulella and some common plates of cystids, but no Ostracods. Edom put out of this shale a Para- doxides.
