Not illustrated. 1903 edition. Excerpt: ... POLYCHJETA FROM THE COASTAL SLOPE OF JAPAN AND FROM KAMCHATKA AND BERING SEA. BY J. PERCY MOORE. Hitherto our knowledge of Japanese Polychaeta has been limited to collections made in the littoral zone at several points along the southeastern coast between Yokohama and Nagasaki and ably described in three papers by v. Marenzeller, a few species from the Japan Sea described by Grube and McIntosh, and to the results of about half a dozen dredge and trawl hauls made by the "Challenger" at points off Japan, which have been recorded by McIntosh. At the close of an extended cruise in the South Pacific Ocean, the United States Fish Commission steamer "Albatross" spent the month of May and part of June, 1900, in dredging and trawling along the continental slope of Japan. During this cruise the vessel was in command of Captain J. F. Moser, U. S. N., with Dr. H. F. Moore as naturalist, to whom, and to Dr. H. M. Smith, of the Fish Commission, I owe the pleasure of studying the rich and interesting collection of Polychaeta taken.1 During May a line of about seventy dredging stations was run along the coast of Nippon or Hanshu from Yokohama westward about 200 miles, through Sagami and Suruga Bays and the Totomi Sea. These stations were mostly along the steep slope on the inner border of the Black Current, and about or within the 100-fathom line, though the trawl was sometimes sent down to much greater depths. In early June, ten additional stations were established along the coast of northern Nippon, beginning at the lower end of Sendai Bay and extending for about 120 miles northward, entirely within the 100-fathom line. Later in June several dredgings were made in the shallow waters and muddy bottoms off Kamchatka, and others north of the Aleutian...

Contains 67 original papers by nearly 100 of the world’s leading specialists. Together with abstracts and literature references for 37 presentations not represented by papers, this volume provides complete coverage of the Conference and a comprehensive overview of modern research on the polychaete annelids, one of the most important groups of marine invertebrates and constituents of marine benthos. Taxonomic and subject indices of all papers and abstracts provide ready access to the contained information. Richly illustrated, this book is provided with numerous line drawings, and photomicrographs, electron micrographs. Over 60 taxa are newly described or reassigned, and detailed reviews, revisions or redescriptions are provided for five families, one subfamily and numerous genera and species, with many illustrations of new and redescribed taxa and a pictorial key to the maglonids of Thailand.

The polychaetes of the Atlantic coast of New England are still imperfectly known. The present study attempts to give as complete a representation of the New England polychaete fauna as is now possible, to systematize knowledge of the polychaete species known from this New England region of the American coast, and to furnish keys designed to facilitate their identification.

This book is the third volume in a series of 4 volumes in the Handbook of Zoology series treating morphology, anatomy, reproduction, development, ecology, phylogeny, systematics and taxonomy of polychaetous Annelida. It is devoted to the remaining Sedentaria and the first branches of Errantia. These sedentary polychaetes are Terebellida and Arenicolida, all of which are tube-dwelling and deposit feeders. The tubes may be simple burrows stabilized by mucus or the tubes are highly sophisticated often really aesthetic structures build-up of sediment grains glued together by their secretion. Although the former possess anterior appendages used for collecting food particles, these are likely not modified palps rather than a new acquisition. Many of these species are adapted to occur within environments characterized by low oxygen supply and so many members of these taxa possess elaborated branchiae, usually positioned on a number of anterior body segments except for Maldanidae which look like bamboo sticks and thus earned their common name bamboo worms. Members of Arenicolida and Maldanida may occur in high abundance and as such they create biogenically graded sediment beds. The Errantia part starts with Myzostomida, a group of symbiotic animals associated with echinoderms which have been variously placed within the tree of life. As such they show numerous adaptations to this specific mode of life. The next group discussed within Errantia is Protodrilida, a taxon comprising four families of the former archiannelids which belong to the interstitial fauna. Most likely they evolved by miniaturization from larger ancestors. In contrast to typical errants they do not possess well-developed parapodia and antennae. This taxon is followed by Eunicida characterized by possession of a specific jaw apparatus situated ventrally in the foregut and associated with specific musculature. Also being a species rich group showing various feeding modes some of the smallest and the largest members belong to this taxon.
