Description :


Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 17. Of the volumes currently available in the Antarctic Research Series, this volume is the fourth dealing with the biology of the antarctic seas. These collected papers comprise the results of original investigations, 11 of which are concerned mainly with the identification and distribution of marine plants and animals. In the first of these papers Stewart Springer gives a systematic appraisal of the five species of elasmobranch Rajidae from Antarctica, of which one represents a new and unique species. Heretofore one of the peculiarities of the antarctic ichthyological fauna has been the absence of sharks. In this very significant contribution, the author establishes the most southerly record for any member of the elasmobranchs. The second paper, by Patricia Kott, amplifies our systematic knowledge of the tunicates of the South Atlantic, South Pacific, and Indian oceans. It extends her monograph published as volume 13 of the Research Series under the title of Antarctic Ascidiacea and is based on collections made in the Antarctic through 1967; two new species are included. Additions and corrections to volume 13 are appended to this paper. John C. Markham reports on several lower chordates of the genus Cephalodiscus and discusses the systematics and distribution of the five species known from the Antarctic. The Deep Freeze materials examined in the course of this study were obtained through the U.S. Navy Hydrographic Office oceanographers from icebreakers assigned to task force 43 prior to and after the 1955–1959 International Geophysical Year and precede the National Science Foundation sponsored research now being conducted by the USNS Eltanin and the R/V Hero under the U.S. Antarctic Research Program.

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 58. A systematic study was made of the calanoid copepod genus Euaugaptilus found in Isaacs-Kidd midwater trawl and Bongo plankton net samples taken in Antarctic and Subantarctic waters. A total of 303 adult copepods representing 14 species of Euaugaptilus were found, including five new species (E. hadrocephalus, E. perasetosus, E. aliquantus, E. brevirostratus, and E. austrinus) and seven new records (E. maxillaris, E. nodifrons, E. bullifer, E. gibbus, E. angustus, E. laticeps, and E. oblongus). Euaugaptilus antarcticus (Wolfenden) is restored from synonymy. All species are characterized with pertinent descriptions and illustrations. Keys are presented for identification of the species.

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 47. A systematic study was made of the calanoid copepod genus Haloptilus found in Isaacs-Kidd midwater trawl and Bongo plankton Subantarctic seas and adjacent waters. A total of 799 adult copepods representing eight species of Haloptilus were found, of which only one species (H. ocellatus) was truly endemic to the Antarctic, occurring exclusively in waters south of the Antarctic Convergence. Three other species that were also found in the Antarctic were H. fons, H. oxycephalus, and H. longicirrus, of which the last is a new record and the first two are known as more or less cosmopolitan species. Four warmwater species found at stations just north to the Subantarctic were H. spiniceps, H. ornatus, H. longicornis, and H. paralongicirrus, of which the last is a new record. All species are redefined with pertinent descriptions and illustrations. A key is presented for identification of the species.
