The vertebrate fauna of Rotuma consists of over 425
fish species, no amphibians, 11 terrestrial reptiles, 15
land birds and two native mammals. The zoogeographic
affinity of the Rotuman fish fauna is with the Pacific
plate fauna; in contrast, the affinity of the reptile fauna
is with the Fijian fauna. A species list of Rotuman
occurrence is provided for each of the four vertebrate
groups as well as brief descriptions of the marine and
terrestrial habitats.

The Clipperton atoll (10°18'N, 109°13'W) is closed and holds a
lagoon with marked stratification; surface waters are brackish
(S=4/6%), but deep waters show a salinity close to that of seawater and high concentrations of H2S; temperature and pH are high. In this paper, environmental data concerning the atoll, the lagoon and the surrounding ocean are recalled and are followed by the study of the zooplankton of the lagoon and ocean.

During October and November of 1961, the Marine Physical Laboratory of the Scripps Institution of Oceanography, in cooperation with the British Atomic Weapons Research Establishment, sponsored a series of geophysical measurements on Christmas Island. Continuous recordings of the earth's magnetic field were made simultaneously at various points on the island under the direction of Ronald G. Mason and John Northrop of the Marine Physical Laboratory of the University of California, San Diego.
Satawal is a small flat coral island in the west central Caroline Islands about 1050 km east-south-east of Yap Island, at latitude 7'21' N, longitude 147'02' E. Although its surface is locally somewhat irregular, its greatest height is not more than about 4 meters above mean low water. Its long axis is about east-west and its area is 1.3 square km. It is surrounded by a fringing reef upward of 100 meters wide. It has no lagoon, so would be classified according to Tayama's scheme as a table reef. From the viewpoint of land ecology it is an atoll.
Most of the 96 national monuments designated under U.S. law
are on land. The majority are managed by the National Park
Service, though some are administered by the Bureau of Land
Management and other agencies. At this point neither the
name of the proposed Mariana Trench Marine National Monu-
ment (MTMNM) nor the management structure has been de-
termined. For guidance one could review the process of the
recently designated Papahanaumokuakea Marine National
Monument (PMNM), which is placed within the purview of the
The recorded flora of the raised phosphatic limestone island of Nauru in the equatorial Pacific Ocean consists of approximately 493 species. Only 59 are possibly indigenous, none of which are endemic. The balance is composed of ornamentals, weedy exotics, food plants, and a limited number of other useful cultigens. Twelve of the recorded species are either extinct or were never successfully established on Nauru.
This review was prepared on very short notice, to
provide a summary of what is known to the reviewer at the
time, June 1988, about the natural phenomena of the Marshall
Islands. This was for the use of the members of the survay
team sent to the Marshalls by the Environment and Policy
Institute of the East-West Center, Honolulu. Their mission
was to investigate the remaining relatively natural areas
and the extent of biodiversity in the new Republic of the
Marshall Islands.

Nukutipipi atoll (5 km2), of volcanic origin 16-17 million years old on the Pitcairn (hot spot) Hereheretue line, presents a land flora and fauna of low diversity but with a Pisonia forest and hundreds of resident red-tailed tropic birds. Nukutipipi suffered from the 1983 hurricanes : destruction of vegetation and motu as well as sand lagoon mollusc populations. The north and south rims present original geomorphological structures.
