Notice of recent additions to the marine fauna of the eastern coast of North America

OF Polyzoa about 140 species have beeu identified by the writer from the coast between Cape Cod and Labrador. Nearly all these are Arctic or European species, already known. They are mostly described in Smitt's papers on Arctic Bryozoa. They are also mostly enumerated by the writer: in a Oheck-list of the Marine Invertebrata of this coast, now in type. The following is one of the more interesting new forms. The recent determination of so large a number of American Polyzoa, confirms the decision already arrived at, several years ago, from the study of other classes, that the fauna of northern New England is remarkably arctic and chiefly of northern origin, and that the fauna of Greenland is more allied to that of Northeastern America than to that of Northern Europe. In a valuable paper* on the Podophthalmous Crustacea of our northern coast, just published, Professor S. I. Smith has arrived at the same results for that group.
