| Tropical biologists are often frustrated in their attempts to study plants, animals, and climate in the forest canopy because of the difficulty of access to this region 20-50 meters high. This problem can be overcome by the use of free-standing towers (Pasoh, Malaya; Barro Colorado Island, Panama) or by tree platforms (Ulu Gombak, Malaya). In April, 1978, we constructed a canopy platform and ladder at our study site in the Kutai Nature Reserve, East Kalimantan, Indonesia, to collect data on forest phenology and the travel paths of arboreal birds and mammals. Since our 39 meter-high platform and ladder are economical to construct and safe to use (desirable features) we describe its construction here in more detail. We selected a large (180 cm dbh) Shorea... |

| Several filamentous oomycete species of the genus Halophytophthora have recently been described from marine environments, mostly from subtropical and tropical ecosystems. During a survey of oomycetes from leaf litter of Spartina alterniflora in salt marshes of southeastern Georgia, isolates of four taxa were recovered that bore similarity to some members of Halophytophthora but were highly divergent from isolates of Halophytophthora s.str. based on a combined sequence analysis of two nuclear loci. In phylogenetic analyses, these isolates were placed basal to a monophyletic group comprised of Pythium of the Pythiaceae and the Peronosporaceae. Sequence and morphology of these taxa diverged from the type species Halophytophthora vesicula, which was placed... |

| All 168 known species within the 6 genera of the caddisfly family Helicopsychidae are cataloged. Included are all synonyms, type localities, type depositories and species ranges. A historical summary of the taxonomy used within the family is given as well as the biology of the different life stages on generic level. Due to uncertain taxonomic position Helicopsyche helicoidella (Vallot, 1855), Helicopsyche pupoidea (Gould, 1864), Helicopsyche scalaris Hagen, 1864, Helicopsyche thelidomus Hagen, 1864, Helicopsyche arenifera (Lea, 1834), Helicopsyche braziliensis (Swainson, 1840) and Helicopsyche colombiensis von Siebold, 1856 are not included in the catalog. Helicopsyche fannii Rougemont, 1879 was never described and is listed as nomen nudum. Helicopsyche... |

| This catalogue provides an annotated listing of the liverworts and hornworts from the Guianas (Guyana, Surinam, French Guiana), based on the literature and on new data that have become available in the framework of the “Flora of the Guianas” project. In total 375 species in 93 genera are recorded, including more than 100 species and 28 genera new to the Guianas. A list of synonyms (including 30 new ones), a systematic arrangement of the genera and families, and an index to the collectors are also given. |

| This final part of the Coelenterate type catalogue lists 274 nominal types (183 Gorgonacea, 9 Actiniaria and 82 Scleractinia). Six not previously depicted types are represented by photographic illustrations of their habit. Furthermore lists are provided of schizotypes, i.e. fragments of types housed in other musea donated at some time to the Zoological Museum of Amsterdam, and of missing types, i.e. types, which should be in the ZMA but were found missing in a recent survey of the collections. |

| A comprehensive generic catalogue of the Vespidae is presented. New nomenclatural changes include synonymy of Alastoroides Saussure, 1856, with Paralastor Saussure 1856; Araucodynerus Willink, 1968, with Hypodynerus Saussure 1855; and Paranortonia Bequaert, 1940, with Parazumia Saussure, 1855. Paravespa Bell, 1936, non Radoszkowski, 1886, is a synonym of Eustenogaster van der Vecht, 1966. |

| After Mr. F. T. Valck Lucassen's decease in september 1939 his collections have been transported to the Leiden Museum for better preservation. In 1941 the Rijksmuseum van Natuurlijke Historie, Leiden, could acquire these considerable collections which also included those of Janson (London) and Girard (Geneva). These collections contain a great number of species, often represented by the types or series of types, many of which described by Valck Lucassen himself. In an obituary Uyttenboogaart (1940: 1-2) gave an enumeration of all papers by Valck Lucassen, most of which are on Cetonids. The monograph on the genus Lomaptera, announced by Uyttenboogaart, had to be translated, illustrated and to be made ready for printing; it was published in 1961 by the... |

| This catalogue resulted from our attempts (since 1963) to accommodate and modernize the labelling of type-material of Recent fishes in the collections of the Zoölogisch Museum Amsterdam (ZMA), now named Institute of Taxonomie Zoology, University of Amsterdam. We traced 6625 type-specimens of 714 nominal species or subspecies, 228 of which are primary type-specimens (holotype, lectotype, or neotype); moreover, the collection contains one or more syntypes of 222 nominal (sub-) species. A few syntypes are presently indicated as future lectotype in the collection, awaiting publication by various specialists. Such specimens are not distinguished in this catalogue. It is possible that lectotype designations for some species have been validly published, which... |

| After having examined Gray’s type of Acanthomys leucopus) and compared that animal with my description of Mus leucopus ²), Alston comes to the conclusion 3), “that I have been misled by Gray’s very insufficient description”. I am the first to agree with Alston in this statement. I am much indebted to Mr. Alston for his minute description of the Mus in question, s. n. Mus terrae-reginae. If I had known that Gray’s leucopus has the tail shorter than head and body and the fur above dark reddishand not greyish-brown, I should certainly not have made a mistake in confounding these two distinct species. But I believe it quite impossible to recognize species if they are described so incompletely and inexactly as is the case with the greater part of Gray’s... |

| The current centuries old classification of the family Nephtheidae is still mostly based on colony morphology. In this family the Indo-Pacifc genera Litophyton, Nephthea, Dendronephthya and Stereonephthya, and the Atlantic genus Neospongodes form a complex mix of closely related, poorly described species which cannot be recognized using only colony morphology. Attempts with the more modern approach of comparing skeleton composition (sclerites) have been only partly successful because of the extreme variation of sclerite forms present in these genera. The genus Chromonephthea Van Ofwegen, 2005, introduced for several species previously assigned to Dendronephthya, Nephthea and Stereonephthya, was established with sclerite morphology, but the true generic... |

| In 1904 Eugène Dubois published the first report on fossil mammals from the vicinity of Tegelen. After a century of research the clay-pits from the area are known as a classical locality for Villafranchian mammals. Antje Schreuder's work was particularly important for making the fossils from Tegelen known. Her papers, however, also indicate some problems. The large mammal fossils were gathered by clay-workers in the local ceramic industry, and the fragmentary nature of the fossils is partly caused by injudicious handling while extracting the bones from the clay. Because the Tegelen fossils are chance finds rather than the results of careful excavations, their exact provenance is not established. The only exception is the collection of micromammals, which... |

| A survey is given of the characters used for the differentiation of the species of Synergus Hartig, classified with section II of Mayr. Special attention is given to the phenology of the species, for each of which the life-cycle is schematized, with differentiation in spring- and summer-generation. Two forms, provisionally indicated A and B, could not satisfactorily be identified with any of the known species. Sp. В is a common inquiline of oak-apples; biological observations were made on the larvae. Synergus mutabilis Deitmer, 1924, is synonymized with Synergus albipes Hartig, 1841. |
