No. 1, 13 a large individual, much flattened by pressure : the natural joints of the slate pass through the specimen. The tail and a portion of the body are wanting. I have named this EUiptocephala asaphoides. The ellipse upon the buckler appears to be a characteristic marking, while the ribs and middle lobe resemble very strongly the same parts of the Jlsaphus tyrannus. In its perfect form, the ellipse seem3 to belong to the old and perfect individual. No. 2, is the head of a small individual of the same species. The ellipse in this individual has an anterior segment not to be seen in No. 1, which I suppose may be obliterated by age. No. 3, is a fragment of a trilobite probably, but the ribs bear a different character from those we generally meet with. § 3. Taconic slate, with its subordinate beds. Characters of the Taconic slate. Reasons for the opinion that the coarser beds are not metamorphic. A'atural joints. Enumeration of the principal beds ; their strike. Reasons for making the Hoosic roofing slates sui- ordinate to the Taconic slate. Discovery of fossils : Fucoides and A'ereites. Supposed tube of a JVertites in the coarse slates of Brunswick in Rensselaer county, JVew- York. It may be described as an even-bedded aluminous slate, varying from the finest possible grit to one that is coarse and rather uneven-bedded, and passing into a rock having many of the characters of a sandstone. The fineness appears not to depend upon its distance from the western edge of the formation, or on its nearness to the present primary schists on the east; since the mass 7 (Fig. 7, page 19) is a coarse sandstone in the midst of fine argilla- [Agricultural Repo
