Extract

When looking through the number of the Quarterly Journal of the Geological Society for August, 1905, I saw the paper by Mr. Richardson on the Rhœtic deposits of Glamorganshire and his figure of Plicatula intusstriata, Emmr. At the first glance it struck me that this fossil was closely allied to a group of bivalves, well known to me as occurring in the Chalk, where it is represented by the genus Dimyodon, Munier-Chalmas.
