Our knowledge of the history of this class of vertebrates has been vastly extended, and lines of descent have become revealed which afford new and precious insight concerning the inter-relations of different groups. If it was possible for Agassiz to reconstruct accurately the entire skeleton of a. fish from a single scale, it is possible for us now to treat whole faunas in much the same way, since we are able to trace their origin, migrations and genetic relations--in many cases at least---and on bringing all these facts together, to observe the progress of evolution taking place, as it were, before our eyes. Contributions to our Knowledge of American Triassic Fishes.--We must now turn from this imperfect survey of the scope and progress of the science to an equally rapid consideration of the work that has been 'done on American Triassic fishes. As early as the first decades of the preceding century the pioneers of American geology became interested in the fossil fishes and reptilian foot-prints of the Connecticut Valley sandstone, several communications in regard to them having been furnished by Hitchcock, ' Silliman,2 Mitchell3 and Dekay.4 They were also brought at an early date to the attention of scientists abroad. Brongniart, Agassiz, Lyell and Egerton having successively commented upon them during the first half of the century.
