Potassium-argon ages on 38whole rock samples of lavas and intrusives demonstrate that the main period ofsubaerial volcanism occurred over a relatively short interval of about 0.6 Ma inthe Early Pleistocene. The major shield volcano, Pago, was built between about1.54 and 1.28 Ma ago; its large caldera formed approximately 1.27 ± 0.02 Maago. Partial filling of the caldera by volcanics occurred from shortly after itsformation until about 1.14 Ma ago, and activity on Pago Volcano ended withemplacement of trachyte bodies which have ages of 1.03 ± 0.01 Ma. Constructionof the smaller satellitic Olomoana and Taputapu volcanoes, on the easternand western extensions of the main rift zone through Pago Volcano, took placeover much the same time interval as the volcanism on Pago. The youthful basalticvolcanism on the Manu'a Islands, east of Tutuila, allows a rate of migration ofthe center of volcanism of about 10cmjyr to be estimated. These results arebroadly consistent with a hot spot origin for the volcanoes.

Previously, the eggs of pelagic, oceanicsquids were virtually unknown. Over 90% of these near-surface plankton towstaken with a l-m net contained squid eggs. About 90% of the eggs were collectedin the upper 100m with most of these coming from the mixed layer. The eggs wereseparate rather than in masses. Two egg types have been identified. One belongsto the Enoploteuthinae, which are thought to spawn individual eggs. The otherbelongs to the Brachioteuthidae, whose spawning mode is unknown. Mostsquids are thought to deposit eggs in masses. Estimates, based on the abundanceof the captured eggs, indicate that the chances of sampling an intact egg masswith a plankton net are small.

The smallest reproductively activefemale measured 380mm standard length (SL); the smallest spermiogenic malemeasured 353mm SL. Only one gonad develops in each sex.Peru has a highly diverse (Chirichigno 1980) but little studied fish fauna. In aneffort to add to our knowledge of the reproductive biology of Peruvian fishes,samples of the little-known belonid fish Belone stolzmanni were obtained. Therange of this fish extends from the Gulf of California (Mexico) to the IslasChincha (Peru) and the Galapagos Islands (Chirichigno 1980). Nothing is knownof its reproductive biology . The purpose of this note is to provide a histologicalanalysis of gonad samples collected during summer.

Observations were made during peak firetree fruiting(October-November 1983) in areas where 'ohi'a (Metrosideros polymorpha) andfiretree are codominant. Both native and introduced birds foraged in firetree and'ohi' a, but introduced birds were more common in firetree. Ofthe six bird speciesobserved, 'oma'o (Phaeornis obscurus) and house finches (Carpodacus mexicanus)were the principal dispersal agents in the areas studied, while the common'amakihi (Hemignathus virens) was secondarily important. Japanese white-eyes(Zosterops japonicus), though feeding on the fruit, rarely ingested the seed.'Apapane (Himatione sanguinea) and Northern American cardinals (Cardinaliscardinalis) were not observed eating firetree fruit. Germination rates and successesof several native and alien species are generally unaffected by passagethrough the digestive tracts of captive Japanese white-eyes and common mynas(Acridotheres tristis).

Eleven of the species represent new records for theatoll, and five are new for the Marshall Islands. A systematic resume of eachspecies is presented, including observations on diel activity patterns, degreeof exposure when active, and current requirements deduced from local distributions.More than half of the species were strictly nocturnal. Densities ofnocturnal populations were much higher than those typically observed duringthe day . Occurrence and distribution of crinoids about the atoll appeared to beinfluenced by prevailing currents. Some species, of predominantly cryptic andsemicryptic habit by day, occurred at sites both with and without strong currents.While these species were able to survive in habitats where currents prevailed, theyappeared not to require strong current flow. In contrast, the remaining species,predominantly large, fully exposed comasterids, were true rheophiles; these werefound on seaward reefs and only on lagoon reefs in close proximity to tidalpasses . Comparison of crinoid records between atolls in the Marshall Islandsshows Kwajalein to have the highest diversity , although current disparitiesbetween atolls in the number of species recorded undoubtedly reflect to someextent differences in sampling effort and methods. Based on pooled records, atotal of 14 shallow-water crinoid species is known for the Marshall Islands,compared with 21 for the Palau Archipelago and 55 for the Philippines. TheMarshall Islands comatulid fauna is predominantly an attenuated western Pacificfauna, dominated by widely distributed members of the family Comasteridae.A field identification key for crinoids of the Marshall Islands is provided.
