Fine-grained and light-coloured shale, with great abundance of Cordaites Robbii, and Calamitea transitionis; above that a layer of coarse shale, with Cordaites, and stems of plants badly preserved, then a layer of soft, very friable shale, with few fossils; and, lastly, a layer of coarse shale of a greenish-gray colour, with— Pecopteris discrepans, Daws. Abundant.—Cordaites Robbii, Daws. Abundant.—Calamites canncB/ormis, Brongn. iVieu- roptcrispolymorpha, Daws.—Cardiocarpum cormdum, Daws.— Cardiocarpiim obliquum, Daws.—Pecopteris, sp. nov. Occurs abundantly in some of the overlying beds. Sandstones and coarse shales, with abundaice of plant-remains, principally Cordaites and Calamites 5 feet. Plant-bed No. 7 2 „ This is one of the richest plant-beds of the section. The shales composing it vary much in character in different exposures. They arc for the most part of a gray colour, and compact, like a fine-grained sandstone, though they pass into a light-brownish, very fissilcj soft shale, and there are some layers of a very black colour. Cordaites Robbii, Daws. Very abtmdant, and in a beautiful state of preservation.—Calamites transitionis, Goeppt. Not abun- dant as good specimens.—C. cannaiformis, Brongn. Rare.— (?) Asterophyllites acicularis, Daws. In very beautiful specimens, very common in certain thin layers. There arc two or three other species, occurring also in the overlying beds, which appear to be new.—Annularia acuminata, Daws. Extremely plentiful.—Pinnularia dispalans, Daws. Extremely plentiful.— (?) Psilophyton elegans, Daws. I have obtained several specimens of a Psilophyton, growing in tufts, and closely resembling this species.
