Description

Excerpt from Pal?ontology: Part I. Containing Descriptions and Figures of the Fossil Brachiopoda of the Upper Helderberg, Hamilton, Portage and Chemung Groups, 1862-1866

Notio, - In the earlier pages of this volume, printed in 1862, a few species of the genera lingula and D180 ina were described from the Waverly sandstones of Ohio, there having been at that time no sufficiently well marked limit established between the western extension of the Chemung Group and these beds. Farther comparison of species of other genera led to a doubt of the propriety of uniting these formations on zoological considera tions alone, and some species from the Ohio formation, previously described by me, as well as others at that time under investigation, were omitted from the volume for this reason. It is true, however, that certain species found in the Waverly sandstones and associated rocks of Eastern Ohio, are apparently identical with forms occurring in the Hamilton and Chemung Groups of New York; but these are comparatively so few, that their recurrence can only be regarded as due to a repetition of the same or similar physical conditions in the two or more epochs.
