CAIRNS I SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 486 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover. Robert McC.

Cairns SMITHSONIAN INSTITUTION PRESS Washington, D.C. 1989 ABSTRACT Cairns, Stephen D. A Revision of the Ahermatypic Scleractinia of the Philippine Islands and Adjacent Waters, Part 1: Fungiacyathidae, Micrabaciidae, Turbinoliinae, Guyniidae, and Flabellidae. Smithsonian Contributions to Zoology, number 486,136 pages, 3 figures, 42 plates, 1989.—Fifty-three species of ahermatypic Scleractinia—about half of the Philippine aher- matypic fauna—belonging to four families and one subfamily are described and illustrated. Five additional species found in adjacent waters just north of the Philippines are also included in the faunistic revision. In order to better evaluate the genus Leptopenus, L. antarcticus, from Antarctica, is also included in this revision as a new species, making a total of 59 species revised. Concurrent with the species revision, higher-level taxa were reanalyzed and revised, resulting in the description of four new genera: Endocyathopora, Thrypticotrochus, Truncatoguynia, and Truncatoflabellum and 17 new species; the formation of 13 new species combinations; and the establishment of two new subgeneric ranks: Fungiacyathus (Bathyactis) and Flabellum (Ulocyathus). To help stabilize the nomenclature of taxonomically confusing species, neotypes were designated for two species: Flabellum (= Truncatoflabellum) cumingii and Flabellum (= Truncatoflabellum) candeanum; and lectotypes were chosen for four other species: Bathyactis (= Fungiacyathus) sibogae, Flabellum pavoninum, Flabellum distinctum, and Flabellum patens. Approximately 4400 specimens were examined from 178 stations throughout the Philippines, as well as most of the previously reported specimens from this area. A historical resume is given of previous literature on ahermatypic Scleractinia in the Philippine Islands. Character tables or keys are provided for the genera of Micrabaciidae, Turbinoliinae, Guyniidae, and Flabellidae, and character tables are provided for the Philippine species of Fungiacyathus, Stephanophyllia, Flabellum (Flabellum), and Truncatoflabellum. The Philippine Islands and Indonesia, especially the Sulu Sea, are considered to be at or near the center of ahermatypic species diversity and thus represent the most diverse ahermatypic fauna in the world. East and west of the Philippines the number of species held in common falls rapidly, but relatively high percentages of shared species are found to the north: 30%-32% for the South China Sea off Hong Kong, and 36%-38% for off Japan. The highest number of shared species, however, is with Indonesia (25-27 species, 47%-51%), with which the Philippines probably forms a zoogeographic unit Of the 53 species reported from the Philippines, 27 are new records for this island group. OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year.
