    Gibsmithia hawaiiensis gen. n. et sp. n.
    (University of Hawai'i Press, 1963-10) Doty, Maxwell S.
    A new genus , Gibsmithia, is described and tentatively placed in the Dumontiaceae of the red algal order Cryptonemiales. Its diagnostic features are: possession of auxiliary cells in specialized filaments separate from those bearing the carpogonia; the known sexual structures occurring in sori at the tips of soft, gelatinous branches which arise from perennial round stems so as to form a hemispherical head; cruciate tetraspores borne on filaments protruding from the surface of the branches and these same branch filaments often bearing terminal seirospores. The type species of the genus is G. hawaiiensis, known only from the island of Oahu in the Hawaiian Islands.

    Characteristic Features of the Volcanism of the Siberian Platform
    (University of Hawai'i Press, 1963-10) Sobolev, V.S.
    Widespead volcanism is characteristic of the Siberian platform, and was especially intense during uppermost Paleozoic and lower Mesozoic time. The Siberian traps, which occupy an area of more than 1,500,000 km^2, are best developed there. These are effusive and hypabyssal rocks of basalt-dolerite type, closely resembling trap rocks in other parts of the globe, especially the Karroo dolerires of South Africa.

    Investigations of Rhinoceros Beetles In West Africa
    (University of Hawai'i Press, 1963-10) Hoyt, Charles P.
    In April, 1959, the author was sent by the South Pacific Commission to the countries of Sierra Leone and Nigeria, West Africa, to conduct an investigation of the natural enemies of the various species of Oryctes (Coleoptera, Scarabaeidae, Dynastinae) occurring there . The object of this study was to find and introduce to the islands of the South Pacific suitable parasites and predators of these beetles in order to establish a biological control over the introduced Oryctes rhinoceros Linn. which has become a serious pest of coconut palms in the area.
