Book Description
This report provides a systematic and nomenclatural review of the thecate hydroids of Bermuda, collected at depths from the intertidal zone to 100 m. The report does not include the superfamily Plumularioidea L. Agassiz, 1862. Synonymies of each of the 9 families, 27 genera, and 46 species represented are given, and descriptions and illustrations are provided for each species. Several new taxa are described: Halecium lightbourni, sp. nov.; Hebellopsis communis, sp. nov.; and Sertularella gayi unituba, subsp. nov. Salacia fraseri is proposed as a replacement name for the junior primary homonym Thuiaria distans Fraser, 1914 (not Thuiaria distans Allman, 1877). The genus Lafoeina M. Sars, 1874, is restricted to stolonal species corresponding with Lafoeina tenuis, type species of the genus. Keratosum Hargitt, 1909, is recognized for those species resembling Lafoeina but having an erect, polysiphonic rhizocaulus. Endothecium Fraser, 1935b; Hebellopsis Hadzi, 1913; and Tridentata STechow, 1920, are re-established as the valid names of genera. Evidence is presented that the families Campanulinidae Hincks, 1868, and Eirenidae Haeckel, 1879, are identical. Of the 46 species discussed, 25 are reported from Bermuda for the first time, 37 have been recorded elsewhere in the western North Atlantic, and 18 are believed to be circumglobal in warm waters.

Book Description
This landmark scientific reference for scientists, researchers, and students of marine biology tackles the monumental task of taking a complete biodiversity inventory of the Gulf of Mexico with full biotic and biogeographic information. Presenting a comprehensive summary of knowledge of Gulf biota through 2004, the book includes seventy-seven chapters, which list more than fifteen thousand species in thirty-eight phyla or divisions and were written by 138 authors from seventy-one institutions in fourteen countries.This first volume of Gulf of Mexico Origin, Waters, and Biota, a multivolumed set edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle, provides information on each species' habitat, biology, and geographic range, along with full references and a narrative introduction to the group, which opens each chapter.

Book Description
The Fourth Edition of The Light and Smith Manual continues a sixty-five-year tradition of providing to both students and professionals an indispensable, comprehensive, and authoritative guide to Pacific coast marine invertebrates of coastal waters, rocky shores, sandy beaches, tidal mud flats, salt marshes, and floats and docks. This classic and unparalleled reference has been newly expanded to include all common and many rare species from Point Conception, California, to the Columbia River, one of the most studied areas in the world for marine invertebrates. In addition, although focused on the central and northern California and Oregon coasts, this encyclopedic source is useful for anyone working in North American coastal ecosystems, from Alaska to Mexico. More than one hundred scholars have provided new keys, illustrations, and annotated species lists for over 3,500 species of intertidal and many shallow water marine organisms ranging from protozoans to sea squirts. This expanded volume covers sponges, sea anemones, hydroids, jellyfish, flatworms, polychaetes, amphipods, crabs, insects, snails, clams, chitons, and scores of other important groups. The Fourth Edition also features introductory chapters on marine habitats and biogeography, interstitial marine life, and intertidal parasites, as well as expanded treatments of common planktonic organisms likely to be encountered in near-to-shore shallow waters.

Book Description
Rocas Alijos lies 180 nautical miles west of Baja California. It comprises several exposed rocks that surmount a large oceanic volcano rising from the ocean floor well off the continental shelf. It is located at the transition zone between two major biologic provinces, at a latitude where the Pacific Current turns westward to form the north Pacific trans-oceanic current. In spite of its obvious importance for biogeographical studies, the remoteness of Rocas Alijos and its small size thwarted any major scientific work until very recently, and the topography, biota, and oceanographic conditions of the site remained largely unknown. During 1990, and again in 1993, Cordell Expeditions, a nonprofit research organization based in Walnut Creek, California, undertook expeditions to describe the site. A scientific team of 30 was onsite 31 October-7 November 1990, and a scientific team of 12 was onsite 10-15 February 1993. Since most of the Rocas Alijos site is subtidal, much of the examination and specimen collection was done by scuba, although several remote sampling techniques were also used. The exposed rocks were sampled by climbers, and megafauna were observed from shipboard.
