Interpretation of SEASAT geoid anomaly data and improved seafloor mapping of the
south-central Pacific suggest a complex tectonic history for the islands of the Pitcairn
group. While Oeno atoll formed at ~ 16m.y.BP at a 'hotspot' now south of the Easter micro-
plate, subsequent progressive island development at Henderson (13m.y.), Ducie (8m.y.)
and Crough seamount (4m.y.) resulted from the lateral leakage of magma from the Oeno
lineation along an old fracture zone, itself originating during the Tertiary reorientation
In a typical High Island coral reef complex of French Polynesia (transect of Tiahura, Hoorea Island, Society Archipelago!, 73 species of decapod Reptantia and stomatopod crustaceans were collected. Over 9 stations localised along the transect, 3 different units of hard coral substrate of simi1ar volume (about 17 litres each), were sampled at each station. The results are discussed from two aspects : the first shows that at least 50 carcinologic species occur within the cavitary biotopes ; 16 species (mainly Xanthid crabs), represent more than 90% of all collected individuals.
This report includes an introductory section on the geography and vegetation, and a main portion listing the species of vascular plants known to occur, or to have occurred, on the island, with detailed descriptions of those of which time permitted a careful study, and brief descriptions of the remaining native species. Those suspected to have been brought by Polynesians in pre-European time are also described and discussed in some detail.
The islands of the southern Cook and Austral groups in
the South Pacific exhibit astonishing differences in geology
and topography, even between closely adjacent islands of
similar ages. Some are sea-level atolls, others have low
fringes of Pleistocene raised reefs, and others substantial
rims of elevated mid-Tertiary limestones, locally known as
makatea. On some islands the relief of the makatea is
subdued, but on others it is dominated by eroded volcanics,
sea-level swamps, and vertical limestone walls. Sixty years
Located at 148°15' West and 15°50' South, in the northwesternmost part of the Tuamotu archipelago (Central Pacific), Makatea island is isolated from its nearest
neighbouring atolls, Rangiroa and Tikehau by about 80 km, and it is 245 km from its closest volcanic neighbour, Tahiti. This island rises at least 3,500 m above the sea floor.
Island ecosystems have proven to be particularly sensitive to
human disturbances (Bourne 1975; Byrne 1980; Jarvis 1979). This was first noted by Charles Darwin in the explanation of his theory of natural selection (Byrne 1980). Since then, qualities of insular species have been examined by various authors in an attempt to understand the basis for island vulnerability.

The Northern Line Islands consists of four atolls aligned on
an an axis which runs from south east to north west. The three southern islands Christmas (Kiritiraati), Fanning (Tabuaeran) and Washington (Teraina) have permanent populations and are part of the Republic of Kiribati. The fourth island, Palmyra, on the north end of the chain, is an unoccupied U.S. possession.

Landing on Swains Island is made on the west side at Taulaga, the only village on the island. Besides a small number of thatched, Samoan- style huts ("fale"), Taulaga has a small white church and a large, barn- like copra shed. Leading from the copra shed to the nearby beach are old railway tracks which were once used to transport copra from the shed to the beach for transfer to cargo vessels. Nearby is a large cleared area that may one day be made into an airport runway to link Swains Island by air to Tutuila, the main island of American Samoa.

Interface habitats, areas where aquatic and terrestrial habitats intersect, play important functional roles. Interface habitats mediate the exchange of resources (e.g.. energy,
nutrients, water), alter abiotic gradients (e.g.. temperature, salinity, pH. sedimentation, nutrients), insulate abutting habitats from disturbances, and serve as critical habitat in
During participation in part of the Fairbridge Expedition
to New Guinea, February to May, 1969, I had opportunity to visit 17 islands and cays east of the New Guinea mainland for sufficient time to assemble reasonably complete collections oi their terrestrial reptilian fauna. The purpose of this paper is to present the results of that survey. Fairbridge (1971 ) has previously published a brief report on the expedition and. a more detailed one is in preparation.

From 0900 on 17 June to 0615 on 19 June 1965 Caroline Atoll was visited by a field party from the Pacific Ocean Biological Survey Program (POBSP) of the Smithsonian Institution. The field party, led by Sibley, collected and made observations on vascular plants, fish, reptiles, mammals, and birds. All islands with the exception of the northern two-thirds of Nake were visited. Prior knowledge of the biota of Caroline Atoll is very scant, deriving almost entirely from the visits of F. D. Bennett in 1835, Devoy in 1875, and the U.S.S. Hartford in 1883.
Fais (Tromelin) is an elevated coral island, surrounded by interrupted cliffs 15-20 meters high, lying some 140 miles east of Yap Island, at latitude 9'46' N, longitude 140'31' E in the western Caroline Islands. It has an area of 2.8 square km, and has a population of about 300 people, Micronesians, speaking a dialect of the Ulithi-Woleai tongue. As with many such raised coral islands, valuable calcium phosphate deposits occur on Fais, the greater portion of which was removed and exported during the period of Japanese rule (1914-1945).

Rangiroa is the largest atoll in the Tuamotu Archipelago, and since the institution of a regular air service, the most accessible; yet in common with other Tuamotuan atolls it has rarely been visited by scientists and is barely mentioned in the literature. Dana (1849) published brief notes following the Wilkes Expedition; but the only full account is that by Agassiz (1903). Agassiz's descriptions are, however, verbose and imprecise, and marred by misinterpretations of major atoll features.
Although ornithological observations have not been the main object of any pliase of our work on the Northern Marshall Islands, numerous notes on birds have accumulated which are here placed on record, The birds were identified by use of Ernst Mayr's "Birds of the Southwest Pacific!' and the names used here are mostly those accepted by Mayr in that work. UnIortunately it was impractical to document these records with specin?ens. The sight observations presented should therefore be acceprcd with some reservations.

The Gilbert Islands are a part of the Gilbert and Ellice Islands Crown Colony of Great Britain. They lie in the Pacific Ocean directly southeast of the Ilarshall Islands and are located between the parallels of g045' S. and 3'30' N. latitude, and the meridians of 1720301 E. and 177 15' E. longitude. All of the islands in this groui3 are low islands related to atolls. They are inhabited by Micronesian and Melanesian people who are greatly dependent on materials from the sea for food.
