    Description: In March, 1979, core drillings were made on Vernagtferner (Oetztal Alps, Austria). The entire core I (81 m) was divided into 2.5 cm sections, from which 2H and 180 measurements were made. The measurements on core II (45 m) were made only along selected sections. A summary is given of the changes which occur in the deuterium excess d due to evaporation or melting in a snow cover. The resulting oscillations in excess d values are then used for dating the ice in core I. These oscillations in excess d resolve the yearly firn and ice layers better than the corresponding oscillations in the 2H or 180 content. An age of between 75 and 83 years, and a corresponding average yearly accumulation rate of between 0.85 and 0.77 m water equivalent was calculated for the core. Although a comparison of the isotope contents in core J with temperature data from Vent (Oetztal) yields a discrepancy of four years, the rise in temperature in the second half of the 1940's is clearly reflected by a corresponding rise in isotope content along the core. The results of these isotope analyses are also compared to results from an earlier core drilling on the Vernagtferner, as well as from a core drilling on the cold Grenzgletscher, Switzerland.

    Description: In March 1979, on Vernagtferner (Oetztal Alps, Austria) two cores, I (81 m) and II (45 m), had been drilled the 3H content of which was measured. The cores show clearly the increase of the 3H content in the deposited precipitation due to the nuclear weapon tests which were performed mainly in the time between 1953 and 1962. However, it is difficult to correlate the 3H profiles of core I and II for the layers below 15 m. From the results of core lone can calculate a mean net accumulation rate of 0.7 m water equivalent per year during the time period 1952-1977, the corresponding value of core II being about 0.9 m w. e. per year. The 3H content of former precipitation and of core I is in agreement. Comparing the 3H content of core I with that of a core drilled in 1976 on Vernagtferner one finds general agreement but the concentration peaks do not very well coincide. Traces of up to 10 TV were measured in samples of ice of core I which were taken randomly from depths below. These are supposed to originate from young meltwater penetrating into the glacier.

    Description: The long historical record and extensive modern observations for the Vernagtferner make the glacier a prime object for modelling of its present state and past fluctuations. Historically, the glacier appears to have passed through two radically different phases, characterized by cyclic surging and by shrinkage back into higher accumulation-favorable regions, respectively. A unified computer simulation of this bimodal behavior on a highly complex bedrock topography remains beyond the power of existing glacier models. However, the essentials of the two phases have been reproduced. It appears that the surging mode of flow could operate only as long as the glacier remained large enough to create substantial basal melting through the combination of high base stresses and rapid flow rates. The velocity and thickness profiles observed during the retreat phase are shown to be well simulated by a deformational flow model including parameterizations of the most essential three-dimensional features. The great retreat of the glacier since 1848 appears to have resulted from a climatic mass balance decrease over its entire surface of order 0.2 rna - I superimposed on an enlarged post-surge ablation region. This interpretation holds the potential for future readvance, and perhaps an eventual return to the surging mode, foreshadowed by the recent general thickening of the Vernagtferner.

    Description: The occurrence of permafrost in the region of the Hochebenkar rock glaciers has been mapped in detail. For this purpose basal temperatures of the winter snow cover were measured at over 250 sites (BTS-method), 11 refraction-seismic profiles were taken in frozen and unfrozen unconsolidated sediments and 12 springs were investigated in terms of their summer temperature variations. The combination of seismic refraction and the BTS-method allows rapid and reliable mapping of alpine permafrost, and at the same time enables differences in active-layer thickness to be established. The results of the observations confirm the ideas developed in the Swiss Alps in recent years about the relationships between permafrost and rock glaciers: rock glaciers are creep phenomena of discontinuous alpine permafrost.

    Description: Subglacially precipitated calcites, formed since 1860, are exposed by the retreating of the Tsanfleuron glacier in the Swiss Alps. They have been sampled together with different types of ice and water, for their isotopic composition. The isotopic study suggests that the initial water, from which calcium carbonate is precipitated by partial freezing, is produced by melting of the basal ice layer, not of glacier ice. Because of the wide range of isotopic composition of basal ice, some doubts are expressed on the possibility given by such subglacially precipitated calcites to determine the isotopic composition of Pleistocene ice sheets and to correct the paleotemperature scale.

    Description: Three females belonging to this species were obtained from the branchial cavity of Microcosmus exasperatus at Spanish Water, Cura\xc3\xa7ao, April 3, 1920. They were not fully grown but measured about 4.50 mm in length, and the large incubatory pouch was filled with minute eggs.\nThis is the species described by THORELL and referred by him to the genus Doropygus, but it differs so much from the other species of that genus that both GIESBRECHT and SARS recognized it as generically distinct. GIESBRECHT referred it to COSTA\xe2\x80\x99S genus Notopterophorus, and SARS created for it the new genus named above, which seems to be correct.

    Description: As I have already pointed out in the Narrative of the Voyage (this journal Nr. 23) there is a marked difference between Caracasbay and Spanish Water, the former having clear blue ocean water, the latter being rather muddy. Spanish bay is quite the same as Caracasbay except that it is less sheltered against the tradewinds. Spanish Port is a narrow channel connecting Spanish Water with the bay and shows the transition in the different nature of the water. This difference has a great influence on the fauna as is shown especially by the coral population.\nFor the rest the coralfauna of the West Indies is extensively described by POURTAL\xc3\x88S (III. Cat. Mus. Comp. Zool. No. IV. 1871), VERRILL (Trans. Conn. Ac. Vol. 11. 1901), and VAUGHAN (The stony corals of the Porto Rican waters. U. S. Fish. Comm. Bull. Vol. 2. 1901; Some fossil corals from the elevated reefs of Cura\xc3\xa7ao, Arube and Bonaire. Samml. des geol. Reichsmus. in Leiden, 1901; Fossil corals from Central America, Cuba, and Porto Rico, with an account of the American tertiary, pleistocene, and recent coral reefs. Smiths. Inst. Bull. 103. 1919; etc.).

    Description: The sipunculan Aspidosiphon exiguus Edmonds, 1974, is recorded from Bonaire and Cura\xc3\xa7ao (Netherlands Antilles). It was first described from three localities in Cuba. Unlike most aspidosiphonids, the species seems to belong to the interstitial fauna of marine beaches and appears to be tolerant of considerable changes in salinity of its environment. A redescription of A. exiguus, based on the specimens from the Netherlands Antilles, is given.

    Description: Area-species graphs for stygobiont Crustacea Malacostraca of seven islands in the southern Caribbean have been compared. It appears that the \xe2\x80\x9cconstants\xe2\x80\x9d C and z of these graphs are influenced by the geological time elapsed since the island\xe2\x80\x99s emergence. In older islands the values for C and z are higher than in younger islands. The values for z of younger and older islands are much higher (0.79-0.97) than usually obtained in literature for terrestrial animals (0.20-0.40). This may be explained by the very limited dispersal faculties of K-strategists, such as stygobiont Malacostraca.

    Description: For the reason that no records for this group of animals have been made anywhere near that region, the Bryozoa collected by Dr. C. J. VAN DER HORST are of great interest. The collection is quite limited in the number of species, as might have been expected on account of the inconspicuous nature of most of them. Only the specialist in the group, accustomed to collect these minute animals and familiar with their habits of growth, occurrence and appearance, need ever expect to take a very complete series of them. Most of the species in the collection appear to be there incidentally, attached to shells, corals, etc., and were later found on close inspection. A considerable number of the species are represented by only one or two specimens and the examination of debris under the binocular microscope yielded several species in the form of minute portions of colonies. No doubt the bryozoan fauna of the waters about Cura\xc3\xa7ao includes several times as many species as appear in this report.\nIt is a typical collection of the tropical seas as far as it goes. Most of the species represented here are found in the Florida waters, where they have been recorded by SMITT (1872\xe2\x80\x9473) and OSBURN (1914). LEVINSEN (1909) has listed incidentally a few of the species for the region about the Virgin Islands (at that time the Danish West Indies). Otherwise, practically nothing is known of the Bryozoa in all that vast region which includes the West Indies, the Caribbean Sea and the Gulf of Mexico.

    Description: Die Poriferen-Ausbeute der Cura\xc3\xa7ao-Expedition Herrn Dr. C. J. VAN DER HORSTS verdient nach zweifacher Richtung besonderes Interesse. Einmal gew\xc3\xa4hrt sie in die Schwammfauna des s\xc3\xbcdlichen Teiles des Karaibischen Meeres Einblick, von der bisher erst sehr wenig bekannt ist. Seit der \xe2\x80\x9eArgo\xe2\x80\x9d- Expedition des Jahres 1876 ist die Spongien-Fauna dieses Gebietes nicht mehr untersucht worden. Ueber die Spongien von Cura\xc3\xa7ao lagen bisher in der Literatur \xc3\xbcberhaupt noch keine Angaben vor. Sodann liefern die Sammelergebnisse und Standorts-Aufzeichnungen Dr. VAN DER HORSTS Angaben \xc3\xbcber die \xc3\xb6kologischen Anspr\xc3\xbcche einer Reihe westindischer Schwammarten. Es ist kaum n\xc3\xb6tig zu bemerken, dass hier noch fast v\xc3\xb6llig Neuland vorliegt.\nDie Schwamm-Ausbeute, von der im folgenden das Ergebnis der Bearbeitung der Kalk- und Kieselschw\xc3\xa4mme (ausschliesslich der Hornschw\xc3\xa4mme) mitgeteilt werden soll, wurde von Herrn Dr. VAN DER HORST im April und Mai 1920 an der S\xc3\xbcdk\xc3\xbcste von Cura\xc3\xa7ao gesammelt. Es handelt sich um Litoralf\xc3\xa4nge, die im Wesentlichen in zwei \xc3\xb6kologisch sehr verschiedenartigen K\xc3\xbcstengebieten gemacht wurden: Der Caracas-Bai, einem Gebiet der offenen K\xc3\xbcste mit v\xc3\xb6llig klarem Wasser, teilweise der Brandung ausgesetzt, und \xe2\x80\x9eSpaansch Water\xe2\x80\x9d, einer Lagune, die mit dem offenen Meer nur durch einen schmalen Kanal (\xe2\x80\x9eSpaansche Haven\xe2\x80\x9d) in Verbindung steht, und deren Wasser regelm\xc3\xa4ssig starke Tr\xc3\xbcbungen zeigt. Einige wenige Spongien wurden auch aus dem eben erw\xc3\xa4hnten Meeresarm \xe2\x80\x9eSpaansche Haven\xe2\x80\x9d selbst mitgebracht.

    Description: North Atlantic coastal waters harbour two closely related sympatric sponges belonging to the genus Halichondria, viz. H. panicea and H. bowerbanki. From the study of their littoral and sublittoral microdistribution and ecology in the Oosterschelde area (= Eastern Scheldt, S.W. part of The Netherlands) it is concluded that both occupy largely similar niches, although it was found that H. panicea is better equipped to endure exposure to air since it occurs up to a higher intertidal level than H. bowerbanki, while the latter is better equipped to withstand siltation. Other environmental factors as depth, light, current velocity and salinity affect the distribution and behaviour of both species similarly. From these observations it can be inferred, that speciation from a parent species cannot have been sympatrically through ecological segregation of individuals. The possibilities of geographical isolation of populations of a parent species on both sides of the Atlantic Ocean during past glacial periods resulting in an originally American species ( H. bowerbanki) and an originally European species ( H. panicea) are discussed.

    Description: The morphology of the only two known hypogean Paranthuridae ( Cruregens fontanus Chilton, 1881; Curassanthura halma Kensley, 1981) is described. Curassanthura has no closely related marine relatives and must be placed at the base of the more specialized Paranthuridae; Cruregens is closely related to the specialized genus Colanthura, which lives in the upper littoral. Comparing the hypogean paranthurids with Colanthura, several analogies can be found in the hypogean species (body slender, only P 1 with stout subchela, P 4-6 slender, P 7 missing, uropods slender or short and bearing long setae), which can be explained from the way of living of the Paranthuridae.

    Description: The need for better and more systematic descriptions of the chaetotaxy (especially data concerning the shape, structure and pattern of distribution of the setae) is emphasized. The historical developments of studies in chaetotaxy are reviewed.\nTwo basic types of cuticular processes can be recognized: setae and pseudochaetae. The former have sensorial and mechanical functions, the latter only a mechanical function. A special type of seta is the aesthetasc or the chemosensorial receptor. Using the shape and structure of the setae, most of them can be classified in the following categories: simple, plumed, serrate and chelate.\nThe importance of developmental studies for the establishment of homologies in chaetotaxy is stressed.\nExamples of functional morphology of setae are discussed. It is emphasized that the functional morphology of most of the setae can be better understood when the whole organ is studied of which the setae are only a component. Not all the setae have an adaptive significance.\nA descriptive model of the chaetotaxy of cypridacean ostracods is presented. The different characteristics of the setae as well as their position on the limbs are coded by letters and numerals using simple formulae.

    Description: After a review of the morphology of the stygobiont species of Cyathura, five new species are described (one from Cuba, two from Haiti, one from Jamaica, and one from Aruba), and additional details are provided for some other species. Considerations are made on the peculiarities of the geographic distribution of the 11 stygobiont species known at present (forming a circum-Caribbean group and an Indo-Pacific one). A study of the relationships between the various species, and comparison with the non-stygobiont (marine or brackishwater) species of the genus, allows the definition of a subgenus Cyathura s. str. (for all non-stygobiont forms and two marine-interstitial ones) and of a new subgenus, Stygocyathura (containing most of the stygobiont species). In the part devoted to ecological aspects, a 11 stygobiont representatives of the Isopoda Anthuridea are taken into account; amongst them the genus Cyathura has been the most successful in colonizing the underground water Realm, the various habitats of which were electively occupied by different species.

    Description: A large number of previously unrecorded specimens of mailed catfishes of the genus Metaloricaria Isbr\xc3\xbccker, 1975 (Loricariinae, tribe Harttiini, subtribe Metaloricariina) is compared with the known specimens from French Guiana and Surinam. This results in the recognition of two subspecies, viz., M. paucidens paucidens Isbr\xc3\xbccker, 1975, from the rivers Oyapock and Maroni (French Guiana, Surinam), and M. p. nijsseni (Boeseman, 1976) from the rivers Suriname, Saramacca, Nickerie and Corantijn (Surinam). These subspecies were originally described as two different species, even within two different genera: Metaloricaria paucidens Isbr\xc3\xbccker, 1975, and Harttia nijsseni Boeseman, 1976. Morphometric and meristic data, together with illustrations are given of the two subspecies. Diagnostic characters of Metaloricaria are provided, and its position within the Harttiini is indicated.

    Description: Popper\xe2\x80\x99s falsifiability criterion, cast in the form of modus tollens, or ((P 〉 Q). ~Q) 〉 ~P, has often been applied to phylogenetic and cladistic theories. A severe criticism of such application is here examined. Questions concerning the universality, strict or numerical, of the propositions involved are irrelevant, but it is clear nevertheless that some workers have used modus tollens in an inappropriate way. Reliance on it is incorrect if the implicational statement, P 〉 Q, is either a definitional or stochastic conditional. But if it is framed as a causal conditional then a Popperian approach to phylogenetics remains viable, although it is doubtful that this is true also of cladistics, which eschews a causal approach.

    Description: Redescription of Australiosoma clavigerum (Verhoeff, 1928) based on topotypical material. Descriptions of two new species of the genus Cladethosoma Chamberlin, 1920: C. gladiator nov. spec., characterized particularly by a daggerlike femoral process of the gonopods, and C. inflatum nov. spec, in which the femoral process of the gonopods is quite strongly developed and transversely inflated. A new genus, Dicladosomella, is proposed for D. segmentata nov. spec.; it belongs to the group of Australiosomatini in which the telopodite of the gonopods is deeply split into two main branches, tibiotarsus and solenomerite, and is distinguished in particular by the solenomerite having a secondary branch in which the spermal channel makes a loop.

    Description: Four described Australian and one described New Guinean species of the tribe Prasiini in fact represent only two species: Lembeja paradoxa (Karsch, 1890) and Lembeja vitticollis (Ashton, 1912), the only representatives of the tribe in Australia. Relationships of the species are discussed. The species are redescribed and structures of taxonomic importance as well as the whole insects are depicted. Study of type-material proved the new synonymies of Lembeja acutipennis (Karsch, 1890) and Lembeja brunneosa Distant, 1910, with Lembeja paradoxa. Lembeja vitticollis is taken out of the synonymy of Lembeja brunneosa.

    Description: The distribution of the genus Cercyon Leach in the Netherlands has been examined. A survey of characters and character-states is provided. Keys to species and supraspecific taxa are given. The distribution of each species is mapped and the male genitalia are figured.\nIt is noted that the presence or absence of an emargination at the apex of the prosternum is an important character in the supraspecific classification of the genus Cercyon. The presence of male adherence discs at the maxillae is not unique for the tribe Cercyonini, but occurs also in the tribes Sphaeridiini and Megasternini.\nC. laminatus Sharp is placed in the subgenus Paracycreon d\'Orchymont. C. alni Vogt is placed in synonymy with C. convexiusculus Stephens. A lectotype is designated for Sphaeridium ferrugineum Fabricius. This species belongs to the genus Leiodes Latreille.\nAlthough the same Cercyon-species occur in dung-samples from the Netherlands, England and Finland, considerable differences in the quantitative species-composition exist. In the last decades C. atricapillus (Marsham) has become very scarce in the Netherlands. Most specimens of Cercyon were collected during spring, except C. laminatus and C. atricapillus, which were more abundant during summer.

    Description: The Lejeuneaceae are the largest family of the Hepaticae with over 1500 species in about 90 currently accepted genera (Gradstein, 1980). Much has already been written on the nomenclatural and taxonomic problems associated with the generic names in this family. A brief review of the problems is given, introductory to the proposals presented here.\nCurrent generic concepts in Lejeuneaceae are essentially based on Richard Spruce\xe2\x80\x99s treatment of the group in his \xe2\x80\x9cHepaticae of the Amazon and of the Andes of Peru and Ecuador\xe2\x80\x9d (Spruce, 1884). Spruce recognized, besides the monotypic Myriocolea Spruce, one single genus, Lejeunea, for several hundreds of species of Lejeuneaceae known at that time. This muchembracing genus was subdivided by Spruce into 37 subgenera. Each of the subgenera received a name in which the generic name \xe2\x80\x9cLejeunea\xe2\x80\x9d was hyphenated with an appropriate, descriptive prefix: e.g. Acro-Lejeunea, Cerato-Lejeunea, Hygro-Lejeunea, Sticto-Lejeunea.

Taxa end\xc3\xa9micos occurren con preferencia en las regiones abiertas y secas en las Islas Gal\xc3\xa1pagos, probablemente debido a que este medio ambiente para selecci\xc3\xb3n natural y evoluci\xc3\xb3n exist\xc3\xada ya hace m\xc3\xa1s tiempo, como es corroborado por evidencia palaeobot\xc3\xa1nica.\nSe trata de caracterizar y comparar la brioflora de Gal\xc3\xa1pagos, aunque las listas de recopilaci\xc3\xb3n para briofloras regionales del tr\xc3\xb3pico hacen falta en una forma tremenda. En comparaci\xc3\xb3n con la brioflora del continente sudam\xc3\xa9ricano la de las Islas Gal\xc3\xa1pagos es un poco pobre en especies; faltan marcadamente taxa de la selva h\xc3\xbameda tropical y de selva nublada.\nLa proporci\xc3\xb3n bastante elevada de hep\xc3\xa1ticas talosas del orden Marchantiales caracteriza la brioflora de las Islas Gal\xc3\xa1pagos como mas o menos mesof\xc3\xadtica y subtropical, a pesar de la presencia elevada de Lejeuneaceae.

    Description: Commercially available tree altimeters are expensive and heavy, and my personal experience with these instruments is thus minimal. During my last expedition I only used it now and then in the base camp to correct my \xe2\x80\x99feeling for estimation\xe2\x80\x99. I have little doubt that colleagues will recognize these feelings. After my return I regretted this attitude to some extent and tried to design a cheap and light alternative device. It is drawn on the next page, and easy to construct: Make a copy of the drawing. Photocopies are generally not exact enough, causing differences to 5 m in this scheme, due to barrel- and cushionshaped distortion by the lens. I advise to copy the drawing by hand on transparent paper. Glue this copy (preferably with epoxy-resin to make it waterproof) on hardboard (plexiglass, thin aluminium). Fix a water-level parallel to the horizontal line (which indicates c. 1.70 m eye-level!).\nAttach a transparent ruler with a thin but distinct straight line. This ruler is attached with a (nylon) bolt and nut (the latter fixed with cyano-acrylate, e.g. Loctite) in order to move the ruler to reach the necessary angle and to keep it in a fixed position easily. It needs some training to keep the righthand eye on the water-level (a small mirror may help here), the accuracy is sufficient when one sees the air-bubble moving or trembling. A much more severe factor causing inaccuracy is the impossibility to estimate in larger trees where the actual summit is hidden behind the crown. When impossible to locate, one can use the rule of thumb, that the actual summit is behind a point about halfway the base and the edge of the crown. An attached string of e.g. 20 metres facilitates to fix the horizontal distance. From the scale it is evident that one should not try to measure a 50 m tall tree from 20 m distance, 40 m is more accurate. The exactness of the device is mainly dependent on the length of the ruler, 25-30 cm is needed. Before fixing the water-level definitively, one should gauge its position by means of a tree or other vertical object (flagpole) of known height.

    Description: Rattans as an example. \xe2\x80\x94 \xe2\x80\x99Minor\xe2\x80\x99 are called all forest products other than timber. Rattan is one of the best-known. In Malaya, according to Dransfield in his book of 1979, there are 104 species; 54 of them are utilized for cane. In addition, 4 are sought for their edible fruits, 5 for their leaves (as thatch and for cigarette paper), 4 for their \xe2\x80\x99dragon blood\xe2\x80\x99 (jernang, used for varnish, red dye, and medicine), 4 have still other uses. This means that over 2/3 of the Malayan rattans are useful to some extent. At present, we can say that \xe2\x80\x99great\xe2\x80\x99 use is made of 12 species, that is more than 1 in 8. Of all species, the stock is in the primary rain forest. For Indonesia, M.H. Simatupang presented a paper The processing of rotan, a minor forest product from the tropical rain forest, to the 8th World Forestry Congress (1978) summarized on page 3222. The total yield was 59,600 tons a year, of which 7000 tons from plantations.\nThe value of rattan in the world trade is enormous: Dransfield (in The biological aspects of rare plant conservation, edited by H. Synge, 1981) adopts an estimate of US$ 1.2 billion, end value, and adds: \xe2\x80\x9dRattan is in fact the most important forest product after timber in southeast Asia. From a social point of view it is the most attractive forest product, tending to benefit local villagers much more directly than timber operations. Traditionally the exhausting and unpleasant task of rattan pulling is carried out during slack agricultural periods (such as after harvest and before sowing the rice crop) and is also greatly influenced by the current price of rubber; when rubber prices have slumped, rattan pulling has become a more attractive source of income\xe2\x80\x9d (p. 180). Dransfield (ibidem, p. 181) credits Borneo with c. 151 species, Malaya with 104, Sumatra with 77, Thailand plus Indo-China with 62, the Philippines with 60, New Guinea with 52, Celebes with 28, Java with 26; his Short Guide to Rattans of 1974 gives 9 for the Moluccas and 2 for the Lesser Sunda Islands. If similar percentages as in Malaya are useful, one can form an impression.

    Description: This book is designed as a practical guide for the identification of fossil and extant woods with the aid of a marginally perforated card key, based on the ones devised by Clarke and perfected in the well-known Hardwood and Softwood keys published by the Princes Risborough Laboratory in 1961 and 1948 (1966) respectively. Using the cards originally prepared for Metcalfe and Chalk\xe2\x80\x99s Anatomy of the Dicotyledons, the Princes Risborough cards, and numerous additions to these sets, the authors have gained considerable experience with this time-honoured identification method. A microfiche of these cards can be purchased separately from the Botanical Museum of Harvard University.\nBesides general chapters and appendices on for instance wood structure and variability, and how to prepare wood for microscopic examination and how to use the key cards, the main body of the book consists of a richly illustrated catalogue of diagnostic characters to be used in wood identification. It is in this section that the book shows most of its weaknesses. This is because of numerous mistakes in the choice of illustrations or misleading legends to the latter. For instance: fig. 3c (p. 24) is said to show abrupt latewood in Larix laricina, but the earlywood-latewood transition zone is not included in the photomicrograph; on p. 68 the vessels of Nyssa are said to be predominantly in multiples of four or more but the photograph illustrates vessel pairs alternating with fibres (i.e., vessel multiples in a distinct radial pattern; the latter feature is illustrated on p. 69 with examples showing no sign of such a pattern at all!); the tangential vessel arrangement of fig. 4b, p. 70 is in fact oblique; Myrica is incorrectly credited with ephedroid perforations on p. 73; Sphenostemon pictured with the most beautiful example of scalariform intervessel pits is said to show spiral thickenings instead (p. 74); long and slender pit canals are mistaken for plasmodesmata on p. 83; essentially similar fibre-tracheids in Eucryphia are classified as belonging to two fibre types (p. 87); fibres of Sleumerodendron are mistaken for vascular tracheids and crystals in the Dicotyledons are illustrated with an example from Gnetum (p. 124). The quality of many of the photomicrographs leaves much to be desired.

    Description: INTRODUCTION\nSince April 1972 an ecological trawl-survey programme has been undertaken by the Netherlands Institute for Sea Research (NIOZ), Texel, in the southern North Sea with the R. V. "Aurelia". The main object is to obtain information on distribution, density, biomass and fluctuations of crawling or swimming demersal (epibenthic) fauna such as small fishes, shrimps, prawns, crabs, asteroids, ophiuroids and some gastropods, for the evaluation of the role of these carnivores in the benthic ecosystem of the southern North Sea. Sedimentological aspects of the area are described by Creutzberg & Postma (1979). Within the context of the present paper the most important feature is the mesh of 5 x 5 mm2 of the cod end of the 51/2 m beam-trawl used and the extensive area of 5000-10,000 m2 covered during each haul. These exceptional circumstances resulted into faunistically interesting catches which gave rise to a cooperation with taxonomic specialists of the Rijksmuseum van Natuurlijke Historie (RMNH), Leiden.\nThe present paper deals with decapod crustaceans, collected during "Aurelia"-cruises, which are considered to be scarce or rare in the southern North Sea, completed with data from bottom-samples and other sources. The species in question are: Pandalina brevirostris, Spirontocaris lilljeborgii, Alpheus macrocheles, Pontophilus spinosus, Pontophilus bispinosus, Galathea dispersa, Ebalia tuberosa, Ebalia tumefacta, Ebalia cranchii, Atelecyclus rotundatus, Monodaeus couchii, Callianassa subterranea, Callianassa tyrrhena, Upogeb ia stellata and Upogebia deltaura.\nOf the genus Macropodia a number of specimens have been collected, which partly were identified as M. linaresi. Other specimens, however, represent one or two new species. On Macropodia in the southern North Sea a seperate paper will
