| In NW. Borneo thick series of Tertiary sediments occur which are rich in fossil pollen and spores. The majority of these plant microfossils were derived from the various types of tropical lowland vegetation such as mangrove (Muller, 1964), mixed peat swamp forest and mixed Dipterocarp forest. Some pollen types, however, can be traced to microtherm elements in the montane vegetation. As these cannot have migrated through tropical lowlands, their past distribution is of special interest. It is the purpose of this note to review the stratigraphic occurrence of these montane pollen types and discuss briefly the phyto-geographical significance of the data. The sediments which contain the microfossils can be roughly divided in a near coastal and deltaic facies,... |

| Geology and soils in general Surinam is situated at the northern edge of the very old and stable Guiana shield. Six-sevenths of the country’s surface are occupied by formations belonging to the shield and designated together as the basal complex. However, the Roraima formation does not belong to the complex. It was deposited during the Mesozoic (probably the Cretaceous) as a thick layer mainly consisting of sandstone that covered the greater part of the shield. Later on the original sandstone plateau was dissected, a process accelerated by the uplifting of the shield, and finally it disappeared almost completely by erosion. The former surface is now only represented by the flat tops of some table-mountains one of which is found in the interior of Surinam:... |

| Butterflies of the genus Maniola are known for their large morphological variation, at the inter- as well as intraspecific level. Given the overlap in wing-patterns, habitat selection, and geographic distribution of various Maniola species, genitalia morphology is sometimes the only possibility to tell specimen apart. In this paper we describe diagnostic characters to distinguish different Maniola species by means of their genitalia. Included is also the first detailed description and illustration of the genitalia apparatus of the Sardinian endemic Maniola nurag. Further, we describe two Sardinian individuals with intermediate characteristics between Maniola nurag and Maniola jurtina, and propose that they are hybrids. Further, we shortly discuss the... |

| Mount Akiki (16° 37’ N, 120° 53’ E, c. 2760 m alt.) is one of the highest mountain peaks in the Cordillera mountain range, Luzon Island, Philippines. It is situated in the municipality of Benguet, north-east of Baguio City (a world famous tourist city in the region) and is north-west of Mt Pulog, Luzon Island’s highest mountain peak and the second in the entire Philippines next to Mt Apo in Mindanao (Schoenig et al., 1975; Buot & Okitsu, 1997a; Buot, 1999). Locally the mountain is known as ‘Pulag’, internationally as ‘Pulog’. Knowledge about the vegetation types on Mt Akiki (similar to that of many of the Philippine mountains), is quite wanting despite its importance in biodiversity studies, zonation and sustainable... |

| The hominid bearing strata from the Liang Bua cave on Flores have yielded a large amount of microvertebrate remains. Among these are three mandibles of shrews, the first record of fossil insectivores from the island. The fossils, representing two different species, are not referable to any of the known Recent shrews from Flores, and are probably part of the extinct insular fauna. Since mandibles alone do not offer sufficient characters to allow even a generic classification, they are published in open nomenclature as Crocidura or Suncus sp. A, and sp. B. Από τα στρώματα με Hominidae από το σπήλαιο Liang Bua της νήσου Φλόρες έχει ανασκαφτεί ένας σημαντικός αριθμός ευρημάτων μικροθηλαστικών.

| A taxonomic revision of Scolopia, based on the collections most important for the genus. Of the names of the about 80 taxa previously described in the genus, 28 remained valid; for 2 species and 1 variety a new combination had to be made, 7 new species and 1 new variety were added, and 5 species had to be transferred to other genera. This resulted in a total of 37 species (and 2 varieties); of these, 21 species are found in Africa (15 of them in Madagascar, the Comores, and the Mascarenes), 15 in Southeast Asia and Malesia (incl. New Ireland), and 1 in Australia. |

| As most of the sea bottom in the Dutch part of the North Sea consists of sand, marine fauna that live in association with hard substrates are rarely monitored. We report here on the results of a species inventory in June 2011 done by scuba-diving while focusing on a wreck on the Dogger Bank and on rocky bottoms on the Cleaver Bank. This resulted in various new records of species for the Dutch part of the North Sea. This result appeared for a large part linked to the added value of monitoring with scuba-divers. It is therefore concluded that scuba-divers should be used in addition to the more traditional monitoring methods in which dredges and grabs are used, if one aims at getting an accurate view of the biodiversity present in marine regions like the... |

| A biometrical analysis of preserved specimens of Bufo bufo, supplemented by a detailed examination of the shape of the skin warts, was performed in order to ascertain the taxonomic status of the form described as B.b.spinosus. Indications of a N.-S. clinal variation in the formation of wart thorns and in allometric relations of body elements were found. The validity of the form as a distinct subspecies seems accordingly very doubtful. |

| When revising the indigenous species of the genus Lecidea, I came across a case in which Körber’s Lecidella carpathica appeared to have been misunderstood. As the original description is insufficient for a good understanding of what its author had in hands, a redescription of the type specimen would not seem out of place. For the supply of some material for comparison my thanks are due to Dr R. Santesson, Uppsala. |

| Ahermatypic Seleractinia are very common throughout the tropical western Atlantic, both in number of species and individuals. Of the Scleractinia known from the western Atlantic, there are over twice as many species of ahermatypes (species that do not have symbiotic zooxanthellae) as hermatypes (the shallow-water “reef corals,” all of which have zooxanthellae). This paper is a review of all known species of deep-water Scleractinia that occur in the Caribbean Sea and adjacent waters, all of which are ahermatypic. The term “deep-water” is used here to designate depths equal to or greater than 200 meters; the 88 species treated all have bathymetric ranges that exceed 200 meters at their deepest points. Another 27 ahermatypic species are confined to the... |

| The calyptoblast hydroids Aglaophenia struthionides (Murray, 1860), Eucopella (= Campanularia) everta (Clark, 1896), and Abietinaria spp. in the low intertidal zone at Mussel Point, Pacific Grove, Monterey Bay, California, often bear the adult pycnogonids Tanystylum duospinum Hilton, 1939 and Ammothea hilgendorfi (Böhm, 1879). Larval stages of these pycnogonids were found living and feeding on Eucopella everta. The larvae of Tanystylum duospinum are ectoparasitic. Those of Ammothea hilgendorfi are endoparasitic in the gastrovascular cavities of hydranths. Larvae of both species feed on the gut contents of Eucopella everta, often on the same hydroid colony. |

| 1. The life-cycles of Gammarus duebeni duebeni Liljeborg and G. pulex pulex (Linnaeus) have been studied in three stations (2 in fresh waters on the cliff coast, 1 in rockpools) on the French Channel coast, through monthly sampling during a good year. In every sample, the number of precopulae have been counted, and physico-chemical environmental factors, such as Ca++-contents, chlorinity, pH, and temperature, have been measured. The samples have been tested on homogeneity, after which the cephalic length was measured. Likewise, the sex and the stage of development (females either or not in reproductive stage, males, juveniles) have been determined. 2. In G. d. duebeni as well as in G. p. pulex there appears to exist a linear correlation between the total... |

| The genus Amphiprion Bloch & Schneider, 1801, is represented in the Seychelles by two species, A. akallopisos Bleeker, 1853, and the endemic A. fuscocaudatus Allen, 1972. Throughout its distributional range Amphiprion akallopisos has exclusively been recorded to associate with the clownfish anemones Heteractis magnifica (Quoy & Gaimard, 1833) and Stichodactyla mertensii Brandt, 1835. During the Netherlands Indian Ocean Programme (NIOP) Seychelles Expedition 19921993 this was confirmed for the Seychelles, although the species was predominantly found with H. magnifica, the most common host anemone in the islands. So far, Amphiprion fuscocaudatus had exclusively been reported as a symbiont of Stichodactyla mertensii. During the NIOP Seychelles... |
