. A catalogue of the collection of Cambrian and Silurian fossils contained in the Geological Museum of the University of Cambridge. Paleontology; Paleontology. Ischadites Koenigii, Murch. (Siluria, 2nd ed. pi. 12, fig. 4). There is no doubt this is one of the regular sponges like Sphcerospongia (p. 40). It has a root, and foramen at top, after the manner of Grantia (Bow.). Sponge, new. Palmate lobed. Sponge, cylindrical, vermiform, acrogenous in growth. This is quite new in Silurian rocks, and should be figured. Some of these are doubtful, and are not cata- logued by Prof. McCoy. Chi

Some of these are doubtful, and are not cata- logued by Prof. McCoy. Chiefly from Count Miinster's collection, as Cellepora, &c. BRYOZOA or P0LYZ0A. Low polypoid Mollusca (lace corals, Flustrce, &c.) abound on every quiet sea bottom. New form like Archimedea of the M. Lime- stone of America. Bryozoa, sp. 1. Cells oblong, granular between. Bryozoa, sp. 2. Thick branches, cells perma- nent. Bryozoa, sp. 3. Encrusting on Favosites, gra- nules very prominent. Trematopora (Hall), sp. Branched cells in linear row. See Pal. N. York, Vol. II. p. 149. Discopora? Rising over Syringopora. (Siluria, 2nd ed. pi. 41). Ceriopora ? Branched species (like Hornera in aspect). This may possibly be a coral allied to Ccenites.
