Description

Excerpt from Paleontology, Vol. 5: Part I; Lamellibranchiata, II; Text and Plates, Containing Descriptions and Figures of the Dimyaria, of the Upper Helderberg, Hamilton, Portage and Chemung Groups This volume includes the letter press and plates containing the descriptions and illustrations of the Lamellibranchiata, II, and constitutes a part of Volume V, part I, of the paleontology OF new york. I have already stated, in the preface to the preceding volume, that the original intention was to publish the work as a volume of text and a volume of plates; but the exigencies of publication made it necessary to issue the work in two parts. The inconvenience attending this plan has arisen from the necessity of adding other plates to the first part, in the Monomyaria, following plate lxxx; the plates from i to lxxx having previously been lithographed. In the present volume, the few plates added to the Dimyaria have been num bered xciii to xcvi, following the last number in the preceding volume. These two volumes contain the descriptions and illustrations of all the well known and determined species of Lamellibranchiate shells from the Upper Helderberg, Hamilton, Portage and Chemung groups, which formations are recognized as belonging to the Devonian System; together with a small number of species from the Waverly sandstone, and rocks of corresponding age, which are generally regarded as Lower Carboniferous. A few others have been introduced for the sake of comparison, or to show the distinguishing features of certain genera. The comparatively few species illustrated from the Waverly group are not to be considered as affording full means of comparison with the fauna of the groups below.
