On Populations in Antarctic Meltwater Pools
(University of Hawai'i Press, 1965-10) Thomas, Charles W.
In meltwater pools of the Clark Peninsula area of Antarctica fresh water biota spend most of the year frozen into the ice or in underlying sediments. In the absence of dynamic pressure (as is the case in pools), ice exerts no pressure on organisms. Survival of organisms appears to be a function of their ability to dehydrate: or encyst. Brachionus and cosmopolitan forms have been introduced into Antarctica. The most likely agency of transport is skua gulls.

Chromosome Numbers in Some Pacific Pteridophyta
(University of Hawai'i Press, 1965-10) Brownlie, G.
Haploid chromosome complements are recorded for two species of Psilotaceae, and for 36 species and one variety of ferns (27 species from New Caledonia, 7 species and 1 variety from New Zealand, and 1 species from New Guinea). It is suggested that Schizaea fistulosa Labill , and Schizaea fistulosa var. australis Gaud. are specifically distinct. A further suggestion is made that the cytologically varied species of Lindsaea together with such genera as Loxsoma and Leptolepia may constitute a distinct fern family.
Contribution to the Marine Chlorophyta of Hawaii, II: Additional Records
(University of Hawai'i Press, 1965-10) Gilbert, William J.
The annotated list which follows is comprised mostly of new or previously unreported marine green algae from the Hawaiian Islands. Sources of material studied are listed in an earlier paper (Gilbert, 1962) with the except ion of a few incidental collections forwarded to me during recent months by Dr. Maxwell S. Dory.
New Digenetic Trematodes from Hawaiian Fishes, I

Sexual Dimorphism in the Labrid Fish Pseudolabrus celidotus (Bloch and Schneider) 1801
(University of Hawai'i Press, 1965-10) Choat, J.H.
During a systematic study of New Zealand fishes belonging to the genus Pseudolabrus Bleeker 1861, it was observed that one of the commonest species, P. celidotus, occurred in two distinct colour phases. This was first noted by Richardson (1848) who described the two colour variants as separate species. The subsequent literature did not recognise these as species, but merely as varieties, although the true relationship was not clarified. A study of populations of this species, both in the field and in the laboratory, revealed that the colour differences were due to sexual rather than environmental or geographic factors, and represented a moderately developed degree of sexual dimorphism. An attempt has been made here to examine the relative proportions of each colour phase in selected populations, the sequence of transition from one colour phase to the other, and the sizes at which transition occurs.
New Pacific Records of Juvenile Albacore Thunnus alalunga (Bonnaterre) from Stomach Contents
(University of Hawai'i Press, 1965-10) Yoshida, Howard O.
Because the albacore, Thunnus alalunga (Bonnaterre), is commercially one of the more valuable species of tuna , a great deal of effort has been expended in investigating its biology. Although much has been learned in recent years about the albacore, its age and growth, movements and migrations (Otsu, 1960; Clemens, 1961; Otsu and Uchida, 1963), many facets of the biology of this species still need to be studied. As part of the Albacore Ecology Program, staff members of the Bureau of Commercial Fisheries Biological Laboratory, Honolulu, Hawaii, have been studying the early life history of albacore in order to fill the gaps in our knowledge.
New Records and Observations on the Flapjack Devilfish, Opisthoteuthis californiana Berry
(University of Hawai'i Press, 1965-10) Pereyra, Walter T.
In June 1961 the U. S. Bureau of Commercial Fisheries joined with the Atomic Energy Commission to undertake an investigation of the deep-water ocean fauna in the area contiguous to the Columbia River mouth at depths from 50 to 1050 fathoms (91-1920 m). The main objectives of this project are to describe the benthic fish and invertebrate communities inhabiting the study area, and to define their bathymetric distribution on a temporal basis. Associated with the faunal investigation is a monitoring of the various demersal forms to evaluate the biological transport of radionucleids which may have their origin in Columbia River waters.
Pogonophora from the Eastern Tropical Pacific, including Two New Species of Siboglinum
(University of Hawai'i Press, 1965-10) Cutler, Edward B.
Two species of Pogonophora are described from the tropical Pacific from a depth of 1354 m. They belong to the genus Siboglinum and both are new species, S. albatrossianum and S. ecuadoricum. Empty tubes of another pogonophore are also described. This material represents the earliest known collection of pogonophores.
The Bathypelagic Mysid Gnathophausia (Crustacea) and Its Distribution in the Eastern Pacific Ocean
(University of Hawai'i Press, 1965-10) Pequegnat, Linda H.
A need has long existed for an improved collecting device for capturing the larger and more actively swimming bathypelagic animals of die sea. The Isaacs-Kidd Midwarer Trawl was developed at the University of California's Scripps Institution of Oceanography in 1950 and has largely satisfied this need (SIO Reference 53-3, 1953).
