Item 18: Index - Pacific Science(University of Hawai'i Press, 1964-10)Item The Holothuroidea Collected by the Royal Society Expedition to Southern Chile, 1958-1959(University of Hawai'i Press, 1964-10) Pawson, D.L.The holothurians collected by the Royal Society Expedi tion to southern Chile, totalling 180 specimens, are described . Ten genera (of which one is new) and ten species are represented. Neopsolidium n.g., type species Psolidium convergens (Herouard), is erected to accommodate those species in the genus Psolidium (sensu lato) in which the dorsal plates are reduced to a diameter of about 0.4 mm. The holothurian fauna of southern Chile is generalised, containing few restricted species, and sharing many elements with distant subantarctic islands and with Antarctica.Item Studies in the Helminthocladiaceae, III Liagoropsis(University of Hawai'i Press, 1964-10) Doty, Maxwell S.; Abbott, Isabella A.In the first paper in this series of studies of the Helminthocladiaceae (Dory and Abbott, 1961 ), we have shown that, in two species of Helminthocladia from Hawaii, the female reproductive structures are generally similar to those described by other workers for other species in the genus, and that vegetative structures such as internal cortical rhizoids may be used to distinguish at least the Hawaiian species. In the second paper of this series (Abbott and Dory, 1960) a new genus, Trichogloeopsis, was described as containing three species, one new and two transfers from the genus Liagora. They share a major character in common, that of sterile rhizoidal extensions of the gonimoblast, but again the three species may be distinguished from each other by their vegetative structures.Item Ciguatera and Other Marine Poisoning in the Gilbert Islands(University of Hawai'i Press, 1964-10) Cooper, M.J.Among the animals that live in the sea are many that may be poisonous to eat; these animals include fish, sharks, crabs, molluscs, and turtles. Of all marine animals the most important are fish, which are for so many people an essential source of food. There are a number of different ways in which teleost fish may be poisonous. Some fish are naturally poisonous; puffers for instance are always toxic. Some species of fish can be poisonous at certain seasons; in Fiji there is a species of sardine which may be deadly poisonous in the later months of the year. A third type of poisoning is found where some fish are poisonous to eat when they are caught on certain reefs or parts of a reef, and yet when caught on other parts of the same reef, or on nearby reefs, are perfectly safe to eat. This type of poisoning, known as ciguatera, is common throughout the tropical Pacific, usually on oceanic islands and isolated reefs.Item Spiders from Some Pacific Islands, Part V(University of Hawai'i Press, 1964-10) Marples, B.J.A collection of spiders from various Pacific islands was entrusted to me for examination by the Director of the Bernice P. Bishop Museum in Honolulu, to whom I am indebted. There were 146 tubes, mostly containing a number of specimens, and they had been collected by different people at different times from islands between New Caledonia in the west and Tahiti in the east. Five new species are described and also four allotypes, and a number of additions to faunal lists have been made. The islands, or island groups, ' will be mentioned in alphabetical order, and the descriptions given at the end. Unless otherwise stated the specimens are in the Bernice P. Bishop Museum.Item Native Hawaiian Cotton (Gossypium tomentosum Nutt.)(University of Hawai'i Press, 1964-10) Stephens, S.G.Although the wild cotton, Gossypium tomentosum Nutt., is one of the more common of the few endemic species which still survive on the coastal plains of the Hawaiian Islands, it remains relatively unknown to the geneticist. Elsewhere it has been grown with indifferent success in experimental culture. Under such diverse conditions as those found in the West Indies, southern Mexico, the U. S. cotton belt, and in greenhouse culture, it flowers sparingly and even less frequently sets seeds. As a consequence, experimental studies have been very restricted, and cytogenetic analysis has been confined almost entirely to the few crosses which have been made with annual forms of the related New World species, G. barbadense L. and G. hirsutum L. To the technical difficulties may be added the lack of representative collections of the species in culture. The few accessions studied have usually been obtained from the more readily available Oahu populations, and less frequently from Molokai. These have been supplied to cotton geneticists through the courtesy of resident Hawaiian botanists, J. F. Rock, O. Degener, A. Mangelsdorf, and others, and patiently resupplied as fast as the stocks in culture expired.Item A Study of the Hatching Process in Aquatic Invertebrates: IX. Hatching within the Brood Sac of the Ovoviviparous Isopod, Cirolana sp. (Isopoda, Cirolanidae). X. Hatching in the Fresh-water Shrimp, Potimirim glabra (Kingsley) (Macrura, Atyidae)(University of Hawai'i Press, 1964-10) Davis, Charles C.Item A Hypomaxillary Bone in Harengula (Pisces: Clupeidae)(University of Hawai'i Press, 1964-10) Berry, Frederick H.The herring genus Harengula Valenciennes (as herein restricted) contains five bilateral pairs of bones in the upper jaw (Fig. 1A) . Most other clupeid fishes contain three or four such pairs of bones: premaxillary, maxillary, and one or two supramaxillaries. The extra pair of bones in Harengula is here termed the hypomaxillary. The hypomaxillary also occurs in the clupeid genera Pliosteostoma Norman and Pellona Valenciennes, and its presence has been used to distinguish these two genera from other genera. The presence of the hypomaxillary in Harengula and its usefulness as a taxonomic character in separating Harengula from other closely related genera previously has been overlooked.Item Thoracic Cirripedia from a Southeast Pacific Guyot(University of Hawai'i Press, 1964-10) Zullo, Victor A.; Newman, William A.Item 18:4 Table of Contents - Pacific Science(University of Hawai'i Press, 1964-10)
