    Description: In deze publicatie zal het mineragraphisch onderzoek der loodzinkertsen met hunne eventueele begeleiders bariet en fluoriet uit het Ladinien der Bergamasker Alpen behandeld worden. Na een historisch overzicht van den mijnbouw, die in deze streken reeds aan het begin onzer jaartelling uitgeoefend werd, zal een korte samenvatting der topographie en stratigraphie volgen, waarna de resultaten van het microscopisch onderzoek volgens de methode Schneiderhöhn een plaats zullen vinden. Het onderzochte materiaal is bijeengebracht door de heeren Beyerinck en Visser en door schrijver dezes, gedurende den tijd dat zij voor geologische kaarteeringswerkzaamheden in de Bergamasker Alpen vertoefden. Het materiaal is afkomstig uit de mijncentra gelegen in het gebied tusschen den Brembo en den Serio. In zijn „La géologie de la vallée du Brembo et de ses affluents entre Lenna et San Pellegrino” (Lit. 2) heeft schrijver dezes reeds uitvoerig de stratigraphie en de topographie van de Valle Brembana beschreven, zoodat met een korte samenvatting der stratigraphie en der topographie volstaan kan worden. Hoewel Beyerinck binnen korten tijd een geologische studie van het centraal gelegen gebied het licht hoopt te laten zien, was hij toch zoo vriendelijk mij eenige stratigraphische gegevens te verstrekken, die in de samenvatting verwerkt werden.

    Description: Die Versteinerungen, welche den Gegenstand der folgenden Untersuchungen bilden, stammen aus Asphaltkalken der Insel Buton (holländisch Boeton) und befanden sich teils in der Sammlung vom „Dienst van den Mijnbouw” in Niederländisch Ost-Indien. Andere waren im Besitz von Herrn Prof. Dr. J. H. F. Umbgrove in Delft, der mir alles, mit Einsehluss der erstgenannten Objekte von ihm selber praepariert, übergab, wofür ich ihm hiermit meinen besten Dank ausspreche. Für die Praeparation sind die Objekte einige Wochen in Petroleum gelegt und dann mit Benzin gereinigt, wodurch sie völlig frei wurden, so dass alle Einzelheiten der Skulptur erkennbar sind. Nachträglieh empfing ich noch zwei Exemplare von bereits untersuchten Arten von Herrn Prof. Dr. H. Gerth in Amsterdam. Die Fossilien sind teils von Herrn Dr. Ir. W. H. Hetzel gesammelt, einige von Herrn J. Flemisch, welcher bei der Firma Schuurman Volker beschäftigt war, und andere von Herrn W. F. Germeraad, dem früheren Direktor der „Boeton Maatschappij”. Durch die Anfertigung der mit Hilfe von ultraviolettem Licht erhaltenen Abbildungen und durch Beschaffung von Literatur hat Herr Dr. I. M. van der Vlerk, Lektor in Leiden, mich ganz besonders verpflichtet, desgleichen durch technische Hilfe bei der Herstellung der Photographieen Herr A. C. Rosemeier hieselbst.

    Description: Several investigators have tackled the problem of the main causes that produce the slopes of volcanic cones, especially with a view to explaining the characteristic concave profiles of strato-volcanoes *). A satisfactory result has not been arrived at, however. This became evident to the present author while studying the submarine slopes of volcanoes in the East Indies. A number of submarine sections of isolated volcanic piles were constructed from the echo-soundings of the Snellius Expedition and from the data contained in the fair sheets of the Hydrographical Survey. These sections combined with the corresponding subaerial profiles will be reproduced in the Scientific Results of “the Snellius Expedition, Volume V: Geology, Part 1: Geological Interpretation of the Bathymetrical Results”, together with a discussion of their shapes and the mode of their formation. An explanation of the wet part of the slope is not possible, however, until we understand the agents influencing the dry part. But as we said, this subject has not been adequately treated. An attempt had therefore first to be made to analyse the factors that play a part in the production of subaerial slopes of volcanoes. In order to test the validity of the deductions an experimental investigation was undertaken that will be described below. These experiments were carried out in the laboratory for experimental geology in the Leyden geological institute.

    Description: Als ich im Jahre 1930 zum ersten Male die Bergamasker Alpen besuchte, um in Gesellschaft mit Herrn Bouman ein Gebiet für meine Dissertation zu wählen, waren die orobischen Alpen eine Offenbarung für mich. Diese in alpinistischer und touristischer Hinsicht vergessene Berggruppe besass soviel Reiz, dass meine Erwartungen bei jedem neuen Besuch wieder übertroffen wurden. Für meine Feldarbeit wählte ich ein Gebiet, das an die schon früher von Leidener Geologen kartierte Region östlich anschliesst (vgl. Fig. 1). Es umfasst einen Teil des Hauptkammes, südlich davon den Oberlauf und das Quellgebiet des östlichen Bremboflusses sowie einen Teil des Beckens der Laghi Gemelli und des Lago Colombo, und nördlich vom Hauptkamm das Venina- und Ambriatal bis zu ihrer Vereinigung. Diese Nebentäler des Veltlins gehören zum Stromgebiet der Adda.

Der erste Teil, der in holländischer Sprache erschien (Mededeelingen Nederl. Myc. Vereeniging Bd. 18—20, 1931), war in Anlage und Behandlung kürzer gehalten. Auch diesmal beruht die Bearbeitung auf denselben Sammlungen, wie die Revision usw. von Oudemans und die darauf folgenden Veröffentlichungen hauptsächlich von der Hand von Frl. C. Cool in den Mededeelingen van de Nederlandsche Mycologische Vereeniging. Es stellte sich nämlich heraus, dass ein grosser Teil des Materials, auf dem diese Arbeiten basieren, in mehr oder weniger gutem Zustande erhalten geblieben war. Ausserdem habe ich selber im Laufe der Jahre, in denen ich mich mit den oben genannten Gruppen beschäftigte, ein Herbarium zusammengestellt, in dem die in diesem Teile behandelten Arten mit etwa 2000 europäischen Nummern vertreten sind. Man kann mir vorwerfen, dass ich Zitate aus der holländischen Literatur über das vorliegende Gebiet weitgehend vernachlässigt habe; doch hat dies seine guten Gründe, denn eine Verbesserung aller Bestimmungen meiner Vorgänger und ein Eingehen auf alle ihre Veröffentlichungen hätte viel mehr, meines Erachtens überflüssigen, Platz erfordert. Durch genauere Fundortangabe des untersuchten Materials und im Falle der Herbaria, auf denen Oudeman’s Revision beruhte, auch der abweichenden, ursprünglichen Determination, habe ich diesem Uebelstande weitgehend abhelfen wollen. Wenn es erforderlich schien, wurde auch bei rezenteren Funden die ursprüngliche Bestimmung angegeben.

    Description: Wat ons hier samenbrengt, mag als een blijde gebeurtenis in de geschiedenis onzer Universiteit worden aangemerkt. Het komt toch niet zoo dikwijls voor, dat een nieuw lid aan het complex der universitaire gebouwen wordt toegevoegd. Deze keer geschiedde het nog juist op tijd, want het huidige inzicht in de economische gesteldheid van de wereld is niet zoodanig, dat bewindslieden nog langer belangrijke sommen meenen te mogen toestaan voor inrichtingen van hooger onderwijs en wetenschappen. Sommige van mijn hoorders zullen vermoedelijk denken: terecht. Ik meen ten onrechte, omdat de geestelijke ontwikkeling van een volk slechts mogelijk is, wanneer van bovenaf, dat wil zeggen te beginnen met het hooger onderwijs en dan afdalend via middelbaar onderwijs naar het lager onderwijs, de wedloop met de andere Westersche volken bijgehouden kan worden. Stilstand beteekent onherroepelijk relatieve achteruitgang en naast ruimere zorg voor de beoefening en ontwikkeling der wetenschappen behoort zeker ook ruimere zorg voor de kunsten. Zonder door den staat ruimer gesubsidieerde instituten van kunst zal ons volk geestelijk niet op peil blijven. Tot de voorwerpen van staatszorg, die te stiefmoederlijk bedeeld worden, behooren ook de musea. Het bezitten van schatten, zooals die bijv. hier in Leiden zijn vergaard in zeer brandbare pakhuizen, of wel goed bewaard, maar niet tentoongesteld, is niet te verdedigen. Dat bezit legt verplichtingen aan den eigenaar als houder onzer cultuurwaarden op, verplichtingen, die intusschen tientallen van jaren onvervuld bleven. Ik kan mij dat slechts verklaren, door gebrek aan belangstelling in dergelijke zaken bij de politieke partijen. Er zit politiek geen of weinig muziek in, hetgeen maakt, dat de bewindslieden meer aandacht aan andere dingen moeten besteden. Intusschen pleit dit niet voor het peil onzer tegenwoordige samenleving. Deze korte opmerkingen moesten mij van het hart, alvorens op het bijondere onderwerp, dat ons heden samenbracht, terug te keeren. Wanneer men zelf alle reden tot dankbaarheid heeft, past het links en rechts te kijken om te zien, of ook anderen zich in dezelfde gelukkige positie bevinden.

    Description: Als ich im Jahre 1930 in der Lage war, auf Java etc. zu sammeln, richtete ich im Anfang meine besondere Aufmerksamkeit auf die epiphyllen Lejeuneen. Obwohl „de Frullaniaceis VII” damals eben veröffentlicht war, sammelte ich auch viele Frullanien, in der Hoffnung noch „etwas Neues” zu finden. Studien an meinen frischen Aufsammlungen in Tjibodas, Buitenzorg und Bandoeng und besonders in den Gärten etc. in Tjibodas und Buitenzorg zeigten mir den zweifelhaften Wert mancher kleinerer Sippen aus „de Frullaniaceis VII”. Es ist ohne weiteres klar, dass die meisten Frullanien in recht verschiedenen Modifikationen auftreten können. Andererseits konnte ich auch zweifelsfrei feststellen, dass es sich bei manchen Arten um Komplexe von erblich verschiedenen Sippen handelt, die in manchen Fällen durch ziemlich einfache Experimente wohl zu trennen sind. Die kurze Zeit, welche ich damals in Tjibodas verbringen konnte, ermöglichte nur einige vorläufige Versuche, welche mir aber die feste Überzeugung gegeben haben, dass Experimente uns Näheres über manche polymorphe Sippen lehren können. Es wäre nicht so schwierig, die wichtigsten Modifikationen und erbliche Abweichungen bei manchen Arten zu studieren. Ich glaube aber nicht, dass wir hier, wo es sich durchweg um Epiphyten handelt, solche klare Ergebnisse erwarten können, wie Buch sie bei seinen klassischen Scapania-Experimenten erzielte. Mit schizostipen Lejeuneen sind diese Versuche viel schwieriger. Die Holostipae schliessen sich aber in vielen Hinsichten an die Frullanien an, und so entschloss ich mich, in Zukunft besonders die Revision und Bearbeitung von Frullanien und holostipen Lejeuneen in die Hand zu nehmen, in der Hoffnung, dabei selber einen Teil der notwendigsten Experimente anstellen zu können! Glücklicherweise haben auch meine und die Schiff ner’sehen Schizostipae einen Bearbeiter gefunden. Seit dem Erscheinen von „de Frullaniaceis VIII” habe ich mir stets Rechenschaft abgelegt, welche Probleme im Herbar und welche experimentell zu lösen sind. Ich halte es für den grössten Fehler der modernen bryologischen Systematik, dass man imallgemeinen Zu sehr danach strebt, Lösungen, welche erst in späteren Dezennien experimentell zu erzielen sind, nun schon arbitrarisch nach dem Studium von Herbarmaterial zu diktieren. Es muss uns völlig gleichgültig sein, ob bestimmte Lösungen vielleicht erst in einem folgenden Jahrhundert experimentell zu erreichen sind. Der im Herbar arbeitende Taxonom ist fertig, wenn er das Problem, das später experimentell zu lösen ist, klar umschrieben hat. Hat er die Fragestellung vollständig angegeben, so muss er entweder mit Experimenten oder mit Revisionen anderer Gruppen anfangen.

    Description: Op menig eiland van den Indischen Archipel zijn tertiaire bekkens van sterke daling en sedimentatie geconstateerd. In de literatuur is hun veelal de naam geosynclinaal gegeven. Hun geschiedenis kan als een afzonderlijk verschijnsel en als een afgerond onderwerp beschouwd worden, zelfs indien men de geschiedenis dezer tertiaire z.g. geosynclinalen zou willen opvatten als een onderdeel van de zoo veel langer durende en zeer ingewikkelde historie van dit resteerende deel der Tethys. Ofschoon ik hier niet in stratigraphische bijzonderheden zal treden, zal het toch niet te vermijden zjjn, zoo nu en dan bepaalde niveau’s van het tertiair aan te duiden. Ik gebruik hiertoe de bekende letterindeeling van het Indische Tertiair 1).

    Description: The two paintings which we here reproduce in colour are the work of Raden Saleh, the first Javanese to receive a Western education as painter, and are dated 1865. They represent the Merapi, by day and by night, obviously during the eruption of 1865. Raden Saleh Sarief Bastaman was born about 1814 at Semarang. At an early age he gave signs of an unusual artistic talent, which draw the attention of Payen 1).

    Description: In order to throw more light on the formation of submarine bars and offshore bars or barrier beaches and the minor shore forms beach cusps and ripple marks a series of experiments was made in the new laboratory for experimental geology of the Geological Institution of the University at Leiden. The experiments were carried out in a tank, measuring six by four meters and half a meter in depth in which waves could be produced artificially varying in height from two to about twelf centimeters. The effects of waves on sandy beaches running parallel to or approaching the beach at an angle of fifteen degrees were traced, the beach itself having a slope of two, four or six degrees. Finally especially to detect possible rules for the formation of beach cusps in relation to the slope of the beach and the height and period of the waves some experiments were carried out with valves and valvegrit, for the principal part derived from Macta subtruncata Dac., and with fine pumice-stone-gravel the so-called „bims” Lapilli (original from the vulcanic Laacher-See country in Germany) ranging in diameter from 0.2 to 2 centimeters in which the beach also had a varying slope. Neither of those last two series of experiments gave the results hoped for with regard to the problem mentioned. Many of the results of the effect of waves during the experiments may be found in the numerous photographs and figures in chapter III. The development and the pushing backwards of the offshore bar by the waves are clearly visible in the figures 39, 40, and 41. In all cases the offshore bar was formed by a gradual lateral growing of a number of subaquatic accumulations of sand which were at the same time slowly pushed higher up the slope of the beach. The subaquatic bar and the channel at the back of it, the latter formed by the excavation through the breaking waves, both had a practically stationary position. An almost horizontal terrace was formed between the channel and the foot of the front slope of the offshore bar, the latter being then pushed backwards to its final position and this taking the slope of a beach ridge. When the waves were running parallel to the beach this terrace was covered with somewhat irregular symmetric oscillation-marks and in case of experiments with waves obligue to the beach with slightly asymmetric combined current- and oscillation-ripples. A number of profils through the beach were taken at the end of most experiments. A careful examination of these profiles gave the following results. 1°. The height of the submarine bar increases until the depth above it measured from the mean water-level is equal to half the height of the waves measured from trough to crest (diagram 1, fig. 85). 2°. Only in the experiments with the beach sloping four and six degrees the submarine bar grows beyond the original profile. 3°. The maximal depth of the channel at the back of the submarine bar is approximately equal to the height of the waves (diagram 3, fig. 87). 4°. The height of the offshore bar, driven back to its ultimate position, above the mean water-level is proportional to one third of the height of the waves (diagram 4, fig. 88). 5°. The actual height of the offshore bar, i.e. the height above the original slope of the beach, proved to be almost independent of the height of the waves (diagram 5, fig. 89). It thus turned out that the offshore bar is pushed back more or less according to the height of the waves without any real increase in height and volume. The number of profiles was not great enough to determine the influence of the slope of the beach though it may be established that indications tend to show a relatively small effect. The transportation of sand from the offshore zone to the beach and in the reverse direction and the transport along the beach by oblique wave attack were discussed at much length. In order to separate the zones in which the waves eroded the sea bottom from those in which sedimentation took place two neutral lines were introduced. The first, seaward one already introduced by Cornaglia where the land- and seaward components of the ground waves are supposed to be exactly balanced, inside of which the motion of debris is landward and out-side of which it is seaward. The second, nearer to the beach, where the eroding force of the waves is changed into a constructive agency. The position of this last line giving at the same time the depth at which the waves will break. The diagram 7 in fig. 91 proves this depth below mean water-level to be equal to three quarters of the height of the waves. The neutral line of Cornaglia was located at a maximal depth of two and a half times the height of the waves, a figure very well in accordance with those given by Cornaglia, Heiser and von Boschitsch for the Mediterranean, the Baltic and the Black Sea. It is generally supposed that the material in the offshore zone, deposited on the abrasion platform, cannot be considered as definitely lost for the formation of shore forms though the transport of sand up the sea-bottom slope is still a quite uncontrolable factor in the development of shores. This supposition however is not directly based on the experimental research but for the greater part on a study of the literature and reports of facts, observed in nature. It needs further experiments with coloured sand to prove the exactness of this opinion which are impossible to be carried out in nature on account of the big amounts of sand required. As to the transportation of sand along the beach it was stated that while in nature the litoral drift is divided into beach drifting- and offshore drifting sand, the former due to the oblique advance of the waves, the latter due to wind-generated and tidal currents, in the experiments the beach drifting only is of prime importance. The principal part of the longshore transportation consequently took place in the zone landward from the surfline. The deflection of the outlets, intersecting the full, by the gradual growing of the windward ridge could be seen in the experiments (exp. XIV). The experiments proved that all waves in the very first place tend to form a profile of equilibrium on the one hand by throwing much material on the beach and pushing this back on the other hand by pulling it down to greater depth. Whilst this is happening the transversal transportation of sand predominates strongly the alongshore transportation, the latter getting more importance when the profile of equilibrium approaches its completion. Much attention was paid to the formation of the low and ball of a sandy shore. The conditions during the experiments resemble closely those of a shore line of emergency along which the formation of submarine- and offshore bars is typical. The coast, the sea-bottom offshore over a varying distance from the coastline and the neighbouring coasts must be considered the sources of the material required for their upbuilding. The results of the experiments and a study of the facts brought forth by other investigators lead the author to the conclusion that the submarine bars, parallel to the shore, are formed by the loss of transporting power of the waves at the surfline. The undertow being only a factor in the regulation of the position of this line and not a determinative factor in the formation of the bars. The socalled „Zuwachsriff” of Braun (lit. 3), a transitional form between the submarine bars and the offshore bar, must be formed by the uprush of the waves after the final breaking. The channel at the back of the submarine bar is in the experiments merely due to the excavating action of the surf but in reality tidal- and wind-generated currents will also have some influence on its formation. The changes in form and position of the three or four, sometimes even more parallel bars are believed to be greatest in the zones nearest to and farthest from the beach. The latter, exposed to the effect of all changes in the height of waves, protects the inner zones to a large extent against a stronger attack by an increasing height of the waves. The former being exposed to the relatively greatest changes in depth and receiving much material eroded from the higher beach and the coast. Any submarine bar, build up to its maximum height by one series of waves will suffer erosion from a higher series and probably be driven landwards more or less. The complex of bars in general is a stabile phenomenon with regard to the external form as to the material it is a dynamic and by no means a static equilibrium. The submarine bars being considered fore runners of the offshore bars only a few remarks need be made about the formation of the latter. I wholly accept de Beaumont’s theory according to which the longshore transportation of debris is a factor completely superfluous for the formation of the offshore bars. Even without the slightest litoral drift bars will be build up consisting of material eroded from sea-bottom farther offshore, the slope of the offshore itself and during periods of rough weather from the coast also. The formation of offshore bars as the „Flugelriffe” after von Cholnoky’s theory is strongly rejected. „Flügelriffe” could be called „delta wing-bars”, a name expressing the connection with delta’s to which the bars are attaced and of which they derive their material after the theory mentioned above. The fifth chapter deals with the formation of beach cusps. Observations in the laboratory and along the Dutch shore show that conditions for their formation only are favourable when regular waves advance and retreat strikingly parallel to the beach. It is thought that the backwash plays an important part in the formation of this minor shore form. Starting its course without any momentum it is more apt to be captured and divided into a number of small streams, running down the slope, by small irregularities and depressions in the surface of the beach. The uprush or swash, which swirls over the slope, will try to erase those irregularities as often could be observed in the experiments. Beach cusps are only formed when the eroding power of the backwash slightly exceeds the constructive power of the uprush. In this case an equilibrium will be attained after a small partial erosion of the slope of the beach concentrated in the bays intervening the beach cusps. Whenever the difference between the two agencies becomes greater the whole slope will be eroded. Along the Dutch shore the beach cusps are buid up out of sand, valves and valve grit of Mactra subtruncata Dac. and the little tubes of Pectinaria belgica Pall. and Terebella conchilega Pall. Those consisting of sand are only found in connection with beach ridges, the seaward slope of which is a subject to erosion in the manner described above. The formation of ripple marks during the experiments did not have the authors special interest. It may only be stated that oscillationripples as well as current-ripples were formed. During the experiments with waves parallel to the beach, all oscillation-ripples formed were parallel to the beach. In the experiments with waves running oblique to the beach, the oscillation-ripples in the deeper zones trended parallel to the waves, in the higher zones parallel to the beach while on the terrace at the back of the channel combined current- and oscillation-ripples were formed at a considerable angle with the beach. True current-ripples appeared in the outlets where they were parallel to the beach and with a general trend at right angles to the beach at the back of the offshore bar. The latter are quietly buried by the transgression of the offshore bar in a manner strictly comparable to the fosilization of ripple marks in delta deposits and by the wandering of banks. The author hopes to have found a new ripple-mark, the „backwash sand-wave” which being always parallel to the beach in a fossil state will give fairly good evidence of the position of the ancient beach. And if these sand-waves are found over some distance in a direction at right angles to their trend they clearly show changes in the water-level, which may be due to the pushing of water against a coast, but in sediments with a marine facies is the result of the tides. These ripples, formed by the back wash, show a slightly arched form measuring some fourty to fifty centimeters in length and not more then one or two centimeters in height. They may cover the whole width of the beach after a period of stormy weather and high tide but under normal circumstances, they are formed on the seaward slope of the ridges lying at the front of the beach near to the low-tide line.

    Description: In 1914 the moldavites, australites and billitonites had already been known for many years and the queenstownites had just been discovered and recognised as tektites. In this year A. Eppler communicated that he had received a sphere of obsidian, ± 17 mm in diameter from South America, the place of origin not being known. Both according to his opinion and to that of Professor Weinschenk, it should be ascribed to the tektites. He arrived at this conclusion mainly by the external appearance of the pebble, that showed the same sculpture and lustre as that of most tektites. Otherwise, however, it had a marked resemblance to the terrestrial obsidian. Eppler compared his tektite to South American obsidians and found them to possess the same brownish grey colour in transmitted light, the same refractive index and practically the same specific gravity (the tektite 2.352, the obsidian 2.346). In 1921 Lleras described similar spheres of glass from Columbia; he also considered them to be tektites. Later, however, (1925) in a detailed publication he defended the view of a terrestrial, volcanic origin of these rocks. After the appearance of Stutzer’s paper Lleras (1929) was again converted to the opinion, that they were tektites.

A clear differentiation of the types of eruptions is not easy, because the character of an eruption depends upon a series of factors.

Neither of those last two series of experiments gave the results hoped for with regard to the problem mentioned.\nMany of the results of the effect of waves during the experiments may be found in the numerous photographs and figures in chapter III.\nThe development and the pushing backwards of the offshore bar by the waves are clearly visible in the figures 39, 40, and 41.\nIn all cases the offshore bar was formed by a gradual lateral growing of a number of subaquatic accumulations of sand which were at the same time slowly pushed higher up the slope of the beach.\nThe subaquatic bar and the channel at the back of it, the latter formed by the excavation through the breaking waves, both had a practically stationary position.\nAn almost horizontal terrace was formed between the channel and the foot of the front slope of the offshore bar, the latter being then pushed backwards to its final position and this taking the slope of a beach ridge. When the waves were running parallel to the beach this terrace was covered with somewhat irregular symmetric oscillation-marks and in case of experiments with waves obligue to the beach with slightly asymmetric combined current- and oscillation-ripples.\nA number of profils through the beach were taken at the end of most experiments. A careful examination of these profiles gave the following results. 1\xc2\xb0. The height of the submarine bar increases until the depth above it measured from the mean water-level is equal to half the height of the waves measured from trough to crest (diagram 1, fig. 85). 2\xc2\xb0. Only in the experiments with the beach sloping four and six degrees the submarine bar grows beyond the original profile. 3\xc2\xb0. The maximal depth of the channel at the back of the submarine bar is approximately equal to the height of the waves (diagram 3, fig. 87). 4\xc2\xb0. The height of the offshore bar, driven back to its ultimate position, above the mean water-level is proportional to one third of the height of the waves (diagram 4, fig. 88). 5\xc2\xb0. The actual height of the offshore bar, i.e. the height above the original slope of the beach, proved to be almost independent of the height of the waves (diagram 5, fig. 89).\nIt thus turned out that the offshore bar is pushed back more or less according to the height of the waves without any real increase in height and volume.\nThe number of profiles was not great enough to determine the influence of the slope of the beach though it may be established that indications tend to show a relatively small effect.\nThe transportation of sand from the offshore zone to the beach and in the reverse direction and the transport along the beach by oblique wave attack were discussed at much length.\nIn order to separate the zones in which the waves eroded the sea bottom from those in which sedimentation took place two neutral lines were introduced. The first, seaward one already introduced by Cornaglia where the land- and seaward components of the ground waves are supposed to be exactly balanced, inside of which the motion of debris is landward and out-side of which it is seaward.\nThe second, nearer to the beach, where the eroding force of the waves is changed into a constructive agency. The position of this last line giving at the same time the depth at which the waves will break. The diagram 7 in fig. 91 proves this depth below mean water-level to be equal to three quarters of the height of the waves.\nThe neutral line of Cornaglia was located at a maximal depth of two and a half times the height of the waves, a figure very well in accordance with those given by Cornaglia, Heiser and von Boschitsch for the Mediterranean, the Baltic and the Black Sea.\nIt is generally supposed that the material in the offshore zone, deposited on the abrasion platform, cannot be considered as definitely lost for the formation of shore forms though the transport of sand up the sea-bottom slope is still a quite uncontrolable factor in the development of shores. This supposition however is not directly based on the experimental research but for the greater part on a study of the literature and reports of facts, observed in nature.\nIt needs further experiments with coloured sand to prove the exactness of this opinion which are impossible to be carried out in nature on account of the big amounts of sand required.\nAs to the transportation of sand along the beach it was stated that while in nature the litoral drift is divided into beach drifting- and offshore drifting sand, the former due to the oblique advance of the waves, the latter due to wind-generated and tidal currents, in the experiments the beach drifting only is of prime importance. The principal part of the longshore transportation consequently took place in the zone landward from the surfline. The deflection of the outlets, intersecting the full, by the gradual growing of the windward ridge could be seen in the experiments (exp. XIV).\nThe experiments proved that all waves in the very first place tend to form a profile of equilibrium on the one hand by throwing much material on the beach and pushing this back on the other hand by pulling it down to greater depth.\nWhilst this is happening the transversal transportation of sand predominates strongly the alongshore transportation, the latter getting more importance when the profile of equilibrium approaches its completion.\nMuch attention was paid to the formation of the low and ball of a sandy shore. The conditions during the experiments resemble closely those of a shore line of emergency along which the formation of submarine- and offshore bars is typical.\nThe coast, the sea-bottom offshore over a varying distance from the coastline and the neighbouring coasts must be considered the sources of the material required for their upbuilding.\nThe results of the experiments and a study of the facts brought forth by other investigators lead the author to the conclusion that the submarine bars, parallel to the shore, are formed by the loss of transporting power of the waves at the surfline. The undertow being only a factor in the regulation of the position of this line and not a determinative factor in the formation of the bars.\nThe socalled \xe2\x80\x9eZuwachsriff\xe2\x80\x9d of Braun (lit. 3), a transitional form between the submarine bars and the offshore bar, must be formed by the uprush of the waves after the final breaking. The channel at the back of the submarine bar is in the experiments merely due to the excavating action of the surf but in reality tidal- and wind-generated currents will also have some influence on its formation. The changes in form and position of the three or four, sometimes even more parallel bars are believed to be greatest in the zones nearest to and farthest from the beach. The latter, exposed to the effect of all changes in the height of waves, protects the inner zones to a large extent against a stronger attack by an increasing height of the waves.\nThe former being exposed to the relatively greatest changes in depth and receiving much material eroded from the higher beach and the coast.\nAny submarine bar, build up to its maximum height by one series of waves will suffer erosion from a higher series and probably be driven landwards more or less.\nThe complex of bars in general is a stabile phenomenon with regard to the external form as to the material it is a dynamic and by no means a static equilibrium.\nThe submarine bars being considered fore runners of the offshore bars only a few remarks need be made about the formation of the latter.\nI wholly accept de Beaumont\xe2\x80\x99s theory according to which the longshore transportation of debris is a factor completely superfluous for the formation of the offshore bars.\nEven without the slightest litoral drift bars will be build up consisting of material eroded from sea-bottom farther offshore, the slope of the offshore itself and during periods of rough weather from the coast also. The formation of offshore bars as the \xe2\x80\x9eFlugelriffe\xe2\x80\x9d after von Cholnoky\xe2\x80\x99s theory is strongly rejected. \xe2\x80\x9eFl\xc3\xbcgelriffe\xe2\x80\x9d could be called \xe2\x80\x9edelta wing-bars\xe2\x80\x9d, a name expressing the connection with delta\xe2\x80\x99s to which the bars are attaced and of which they derive their material after the theory mentioned above.\nThe fifth chapter deals with the formation of beach cusps. Observations in the laboratory and along the Dutch shore show that conditions for their formation only are favourable when regular waves advance and retreat strikingly parallel to the beach.\nIt is thought that the backwash plays an important part in the formation of this minor shore form. Starting its course without any momentum it is more apt to be captured and divided into a number of small streams, running down the slope, by small irregularities and depressions in the surface of the beach. The uprush or swash, which swirls over the slope, will try to erase those irregularities as often could be observed in the experiments.\nBeach cusps are only formed when the eroding power of the backwash slightly exceeds the constructive power of the uprush. In this case an equilibrium will be attained after a small partial erosion of the slope of the beach concentrated in the bays intervening the beach cusps. Whenever the difference between the two agencies becomes greater the whole slope will be eroded. Along the Dutch shore the beach cusps are buid up out of sand, valves and valve grit of Mactra subtruncata Dac. and the little tubes of Pectinaria belgica Pall. and Terebella conchilega Pall. Those consisting of sand are only found in connection with beach ridges, the seaward slope of which is a subject to erosion in the manner described above.\nThe formation of ripple marks during the experiments did not have the authors special interest. It may only be stated that oscillationripples as well as current-ripples were formed.\nDuring the experiments with waves parallel to the beach, all oscillation-ripples formed were parallel to the beach. In the experiments with waves running oblique to the beach, the oscillation-ripples in the deeper zones trended parallel to the waves, in the higher zones parallel to the beach while on the terrace at the back of the channel combined current- and oscillation-ripples were formed at a considerable angle with the beach.\nTrue current-ripples appeared in the outlets where they were parallel to the beach and with a general trend at right angles to the beach at the back of the offshore bar.\nThe latter are quietly buried by the transgression of the offshore bar in a manner strictly comparable to the fosilization of ripple marks in delta deposits and by the wandering of banks.\nThe author hopes to have found a new ripple-mark, the \xe2\x80\x9ebackwash sand-wave\xe2\x80\x9d which being always parallel to the beach in a fossil state will give fairly good evidence of the position of the ancient beach. And if these sand-waves are found over some distance in a direction at right angles to their trend they clearly show changes in the water-level, which may be due to the pushing of water against a coast, but in sediments with a marine facies is the result of the tides.\nThese ripples, formed by the back wash, show a slightly arched form measuring some fourty to fifty centimeters in length and not more then one or two centimeters in height. They may cover the whole width of the beach after a period of stormy weather and high tide but under normal circumstances, they are formed on the seaward slope of the ridges lying at the front of the beach near to the low-tide line.

    Description: I. Lygosoma nieuwenhuisii VAN LIDTH DE JEUDE.\nMertens (1929, p. 215, note) mentioned already that the young Lygosoma from Sandakan Bay, North Borneo, which had been referred to L. smaragdinum Less. by Van Lidth de Jeude (1893, p. 252) did not belong to that species but that it was related to L. nieuwenhuisii Lidth (1905, p. 195). Comparison of this young specimen with the type of L. nieuwenhuisii proved that it belonged to this species. The description of the type must however be corrected in some minor points.\nThis single type-specimen was collected during the Dutch Scientific Expedition in Central-Borneo 1894 (\'sRijks Museum van Natuurlijke Historie, Herpet. n\xc2\xb0 4455). The frontal is slightly shorter than the frontoparietals and interparietal together; it is in contact with three supraoculars, the suture with the left third supraocular being very small.\nFour supraoculars followed by a small scale which is the fifth supraocular of the descriptions by Van Lidth de Jeude and De Rooij (1915, p. 202).\nI do not believe that this scale can be called a supraocular; moreover other species described by De Rooij as possessing four supraoculars have this same small scale. Fourth toe with 18 (left) to 19 (right) lamellae below.\nThe length of head and body (snout to vent) is 64 mm., that of the tail 60 mm. (7,5 mm. reproduced) and not 57 mm. and 55 mm. as stated by both Van Lidth de Jeude and De Rooij.\nThe young specimen collected by Mr. J. Chr. Prakke near Sandakan Bay, North Borneo, may be described as follows: The earopening is very small; two very indistinct auricular lobules are present on one side while they are absent on the other. The supranasal is very small, it is wedged

    Description: In continuation of the "Catalogue of the Bursidae" (cf. \xe2\x80\x9eZoologische Mededeelingen", vol. 14, p. 224, 1932), I now publish a list of the Cymatiidae in the collection of our Museum, after having revised that family.\nWe are indebted to the work of KESTEVEN, DALL, PILSBRY & VANATTA, IREDALE, and others, for a more rational classification of the Cymatiidae.\nThis family was formerly composed of two genera, viz. "Ranella" and "Triton" of older authors. In this century, however, as a result of researches on the dentition and the characters of the shell, these two genera have been placed into two separated families: the Cymatiidae and the Bursidae; moreover, according to the above-mentioned characteristics, the tritonoid "Ranellae", belonging to the sections Apollon and Biplex are added to the former.\nThe family of the Cymatiidae contains now, if we follow THIELE\'S interpretation, the following genera: Argobuccinum Brugui\xc3\xa8re; Cymatium Roding; Distortrix Link; Charonia Gistel.\nMoreover, many species, included formerly in the section Epidromus of "Triton", have been transferred to other families Buccinidae and Muricidae, on account of their anatomical characteristics and peculiarities of the shell.\nThe bulk of the collection of the Leyden Museum, of course consists of specimens from our colonies and principally from different localities

    Description: In his paper on a collection of Reptiles and Amphibians from Surinam VAN LIDTH DE JEUDE (1904, p. 84) mentions a specimen of Glauconia (= Leptotyphlops) macrolepis PTRS. Examination of this specimen showed that it differs in several characters from that species and I believe it to be a species new to science which I propose to name in honor of Professor Dr. J. E. W. IHLE of the Zoological Laboratory, University of Amsterdam, who always takes such a kind interest in my work and whom I always find willing to help me with advice.\nLeptotyphlops ihlei nov. spec.\nSyn.: Glauconia macrolepis. VAN LIDTH DE JEUDE, Notes Leyden Museum XXV, 1904, p. 84. (non PETERS).\nType: A single specimen from Toegoemoetoe, Surinam, 19\xe2\x80\x94II\xe2\x80\x941903, collected by the Saramacca Expedition; \'sRijks Museum van Natuurlijke Historie, Leiden, Herpet. n\xc2\xb0. 4466.\nDiagnosis: A Leptotyphlops of the group possessing supraoculars and differing from the other South-American members of this group by the fusing of the basal parts of second upper labial and ocular. From L. macrolepis it differs, besides in the character mentioned, in the second upper labial which extends to the level of the eye and in the rostral which does not reach the level of the eyes.\nDescription: Snout rounded, projecting. Supraoculars present, not very large, separated by one scale, not in contact with the supralabials.\nRostral not quite reaching the level of the eyes. Nasal completely divided.\nThree upper labials, two in front of the ocular and one behind that shield; the basal part of the second supralabial has fused with that of the ocular

    Description: Der von SPIX im Jahre 1825 in \xe2\x80\x9eSpecies novae Lacertarum" auf Seite 17 beschriebene und auf Tafel 18 Fig. 2 abgebildete Thecadactylus pollicaris wurde von CUVIER \xe2\x80\x9eR\xc3\xa8gne animal II" Seite 54 in die Synonymie von G(ecko) mabuia (= Hemidactylus mabouia MOR.) versetzt und die meisten sp\xc3\xa4teren Autoren schlossen sich dieser Ansicht an. DUM\xc3\x89RIL und BIBRON f\xc3\xbchren in Band III ihrer \xe2\x80\x9eErp\xc3\xa9tologie g\xc3\xa9n\xc3\xa9rale" S. 362 die Spixsche Art allerdings nur mit einem Fragezeichen in der Synonymie von Hemidactylus mabouia auf und auch GRAY \xe2\x80\x9e Catalogue of Lizards" S. 154 folgt ihrem Beispiel. Aber seitdem PETERS, der die Spixschen EidechsenArten einer Revision unterzog (Monatsber. Akad. Berlin 1877), Thecadactylus pollicaris SPIX in die Synonymie von Hemidactylus tuberculosus RADDI (= Hemidactylus mabouia Mor.) versetzt hatte, bestand offenbar kein Zweifel mehr an der Identit\xc3\xa4t der beiden Arten.\nNur Schlegel hatte im Jahre 1858 (Handl. Dierk. II, S. 15) Th. pollicaris unter dem Namen Platydactylus pollicaris als eigene Art aufgef\xc3\xbchrt ohne indes seine Ansicht zu begr\xc3\xbcnden. Da\xc3\x9f sie aber berechtigt war, soil in folgendem ausgef\xc3\xbchrt werden.\nBei einer Durcharbeitung der herpetologischen Sammlung des Rijksmuseum van Natuurlijke Historie in Leiden fand der j\xc3\xbcngere von uns beiden ein Glas mit einem Gecko, das folgenderma\xc3\x9fen etikettiert war: Hemidactylus mabouia Mor. sn.

    Description: In der vorliegenden Arbeit ist die Untersuchung eines sehr umfangreichen Polychaeten-Materials niedergelegt, das mir von Herrn Prof. Dr. E. D. van Oort in Leiden und Herrn Prof. Dr. L. F. de Beaufort in Amsterdam zur Bearbeitung \xc3\xbcbergeben wurde. Von diesem Material ist der dem Museum in Leiden geh\xc3\xb6rende Anteil viel gr\xc3\xb6sser als der Anteil aus dem Museum in Amsterdam. Ich habe die Untersuchung \xc3\xbcber die grosse Menge unbestimmten Materials aus dem Leidener Museum mit dem bisher durchaus unbearbeiteten Material aus dem Amsterdamer Museum vereinigt in einem ersten, grossen Abschnitt unter dem Zeichen R\xc3\xb6misch I. In einem zweiten, kleinen Abschnitt unter dem Zeichen R\xc3\xb6misch II. ist die Nachuntersuchung \xc3\xbcber zahlreiche dem Leidener Museum geh\xc3\xb6rende Polychaeten-Typen enthalten, die von Arm. Hansen im Jahre 1881 nach der Sammlung von Ed. van Beneden vom \xc3\xb6stliehen S\xc3\xbcd-Amerika beschrieben worden sind.\nIch verweise bez\xc3\xbcglich dieser Typen auf Abschnitt II. meiner Arbeit.\nDie bisher unbearbeiteten Polychaeten setzen sich zusammen aus Material aus den verschiedensten Weltgegenden. Vertreten sind verschiedene europ\xc3\xa4ische L\xc3\xa4nder, wie Holland, Deutschland, Norwegen, Italien, Frankreich.\nVertreten ist ferner das Kap der Guten Hoffnung, das Rote Meer, der Nordatlantische Ozean, Niederl\xc3\xa4ndisch-Ostindien, die S\xc3\xbcdsee, das WestindienMeer, das N\xc3\xb6rdliche Eismeer, wozu noch einzelne Funde aus einigen anderen Weltgegenden hinzukommen. Ein grosser Teil des Materials stammt von Niederlandisch-Ostindien, ferner aus dem N\xc3\xb6rdlichen Eismeer.\nAus dem letzteren stammt ein ziemlich grosses Material von den Expeditionen des Willem Barents und der Varna; das Westindien-Meer ist u. a. vertreten durch die Sammlung der Yacht Chazalie.

    Description: Durch freundliches Entgegenkommen des Herrn Prof. Dr. E. D. van Oort haben wir im Laufe der letzten Jahre das gesamte Material der Cypraeacea (Moll. Gastr.) des Rijksmuseum van Natuurlijke Historie in Leiden zur Bearbeitung erhalten. Den Grundstock dieser Sammlungen bilden die grossen Serien der Angeh\xc3\xb6rigen der Familie Cypraeidae l) aus Originalausbeuten \xc3\xa4lterer und j\xc3\xbcngerer Sammler in Niederl\xc3\xa4ndisch Ostindien; dieses Material scheint uns ein vollst\xc3\xa4ndiges Bild der Cypraeiden-Fauna der Niederl\xc3\xa4ndischen Besitzungen in Ostindien zu geben, denn seine Reichhaltigkeit besteht sowohl in der Zahl und Verteilung der vertretenen Fundorte, als auch in der Zahl der an den einzelnen Stellen gesammelten Arten und Individuen: es rechtfertigt also eine zusammenfassende Bearbeitung.\nFur die M\xc3\xbchewaltung bei der Zusendung der vielen Tausende von Cypraeiden-Schalen und f\xc3\xbcr manche Auskunft betreffend Fundorte und Sammler sei den Herren Dr. Ch. Bayer und H. C. Bl\xc3\xb6te hierdurch herzlich gedankt. Eine besonders wertvolle Erg\xc3\xa4nzung der Sammlungen des Museums hat uns Herr L. de Priester in Apeldoorn geliefert, dessen Bruder, Dr. W. F. de Priester, als Arzt der K. P. M. in Niederl\xc3\xa4ndisch Indien in verschiedenen Gegenden des Gebietes marine Molluskenschalen gesammelt hat und sich in letzter Zeit uns zuliebe auf das spezielle Sammeln der Cypraeidae verlegt hat. Herr Prof. Dr. B. G. Escher hat uns freundlicherweise die von M. M. Schepman im \xe2\x80\x9ePost-Terti\xc3\xa4r" von NordCelebes gefundenen Cypraeidae zur Bearbeitung \xc3\xbcberlassen: diese pleistoc\xc3\xa4ne Fauna stimmt mit der rezenten in solchem Grade \xc3\xbcberein, dass ihre Einbeziehung in die vorliegende Studie geboten erschien.

    Description: In deze publicatie zal het mineragraphisch onderzoek der loodzinkertsen met hunne eventueele begeleiders bariet en fluoriet uit het Ladinien der Bergamasker Alpen behandeld worden. Na een historisch overzicht van den mijnbouw, die in deze streken reeds aan het begin onzer jaartelling uitgeoefend werd, zal een korte samenvatting der topographie en stratigraphie volgen, waarna de resultaten van het microscopisch onderzoek volgens de methode Schneiderh\xc3\xb6hn een plaats zullen vinden.\nHet onderzochte materiaal is bijeengebracht door de heeren Beyerinck en Visser en door schrijver dezes, gedurende den tijd dat zij voor geologische kaarteeringswerkzaamheden in de Bergamasker Alpen vertoefden. Het materiaal is afkomstig uit de mijncentra gelegen in het gebied tusschen den Brembo en den Serio. In zijn \xe2\x80\x9eLa g\xc3\xa9ologie de la vall\xc3\xa9e du Brembo et de ses affluents entre Lenna et San Pellegrino\xe2\x80\x9d (Lit. 2) heeft schrijver dezes reeds uitvoerig de stratigraphie en de topographie van de Valle Brembana beschreven, zoodat met een korte samenvatting der stratigraphie en der topographie volstaan kan worden. Hoewel Beyerinck binnen korten tijd een geologische studie van het centraal gelegen gebied het licht hoopt te laten zien, was hij toch zoo vriendelijk mij eenige stratigraphische gegevens te verstrekken, die in de samenvatting verwerkt werden.

    Description: Several investigators have tackled the problem of the main causes that produce the slopes of volcanic cones, especially with a view to explaining the characteristic concave profiles of strato-volcanoes *). A satisfactory result has not been arrived at, however. This became evident to the present author while studying the submarine slopes of volcanoes in the East Indies. A number of submarine sections of isolated volcanic piles were constructed from the echo-soundings of the Snellius Expedition and from the data contained in the fair sheets of the Hydrographical Survey. These sections combined with the corresponding subaerial profiles will be reproduced in the Scientific Results of \xe2\x80\x9cthe Snellius Expedition, Volume V: Geology, Part 1: Geological Interpretation of the Bathymetrical Results\xe2\x80\x9d, together with a discussion of their shapes and the mode of their formation. An explanation of the wet part of the slope is not possible, however, until we understand the agents influencing the dry part. But as we said, this subject has not been adequately treated. An attempt had therefore first to be made to analyse the factors that play a part in the production of subaerial slopes of volcanoes. In order to test the validity of the deductions an experimental investigation was undertaken that will be described below. These experiments were carried out in the laboratory for experimental geology in the Leyden geological institute.

    Description: Wat ons hier samenbrengt, mag als een blijde gebeurtenis in de geschiedenis onzer Universiteit worden aangemerkt. Het komt toch niet zoo dikwijls voor, dat een nieuw lid aan het complex der universitaire gebouwen wordt toegevoegd. Deze keer geschiedde het nog juist op tijd, want het huidige inzicht in de economische gesteldheid van de wereld is niet zoodanig, dat bewindslieden nog langer belangrijke sommen meenen te mogen toestaan voor inrichtingen van hooger onderwijs en wetenschappen. Sommige van mijn hoorders zullen vermoedelijk denken: terecht. Ik meen ten onrechte, omdat de geestelijke ontwikkeling van een volk slechts mogelijk is, wanneer van bovenaf, dat wil zeggen te beginnen met het hooger onderwijs en dan afdalend via middelbaar onderwijs naar het lager onderwijs, de wedloop met de andere Westersche volken bijgehouden kan worden. Stilstand beteekent onherroepelijk relatieve achteruitgang en naast ruimere zorg voor de beoefening en ontwikkeling der wetenschappen behoort zeker ook ruimere zorg voor de kunsten. Zonder door den staat ruimer gesubsidieerde instituten van kunst zal ons volk geestelijk niet op peil blijven. Tot de voorwerpen van staatszorg, die te stiefmoederlijk bedeeld worden, behooren ook de musea. Het bezitten van schatten, zooals die bijv. hier in Leiden zijn vergaard in zeer brandbare pakhuizen, of wel goed bewaard, maar niet tentoongesteld, is niet te verdedigen. Dat bezit legt verplichtingen aan den eigenaar als houder onzer cultuurwaarden op, verplichtingen, die intusschen tientallen van jaren onvervuld bleven. Ik kan mij dat slechts verklaren, door gebrek aan belangstelling in dergelijke zaken bij de politieke partijen. Er zit politiek geen of weinig muziek in, hetgeen maakt, dat de bewindslieden meer aandacht aan andere dingen moeten besteden. Intusschen pleit dit niet voor het peil onzer tegenwoordige samenleving.\nDeze korte opmerkingen moesten mij van het hart, alvorens op het bijondere onderwerp, dat ons heden samenbracht, terug te keeren. Wanneer men zelf alle reden tot dankbaarheid heeft, past het links en rechts te kijken om te zien, of ook anderen zich in dezelfde gelukkige positie bevinden.

    Description: Het tweede gedeelte van de berichten omtrent waarneming van geringde vogels, die gedurende het jaar 1932 bij \'s Rijks Museum van Natuurlijke Historie ingekomen zijn, wordt in de hierna volgende lijst vermeld.\nHet gemis van Prof. Dr. E. D. van Oort bij het samenstellen van dit verslag is onzegbaar groot en het verlies niet te herstellen! Aan het werk van Van Oort op het gebied van het ringonderzoek, waarmede hij in 1911 in ons land een begin heeft gemaakt, is het bovenal te danken, dat dit onderzoek een zoo groote bekendheid in Nederland en daarbuiten verworven heeft en dat honderden in den lande daadwerkelijk hunne medewerking hieraan verleenen.\nNog uit zijn naam dank ik dan ook alle medewerkers, zoowel ringers als berichtgevers voor alles, wat zij tot op heden wederom voor het ringonderzoek hebben verricht.\nIn het vorige verslag (XX, 1) Zoologische Mededeelingen, deel XVI, afl. 1/2, 1933, zijn de navolgende verbeteringen en aanvullingen aan te brengen: pag. 12, Wilde eend, no. 36719, ringdatum niet 11 Augustus 1931, doch 8 Maart 1932. pag. 18, Griel, no. 89602, geringd in het Zwarteveld, gem. Amsterdam, moet zijn gem. Zandvoort.\nSteenuil [Athene noctua (Scopoli)].\nRingnummer 101661, geringd te Wassenaar (Z.H.) 27 October 1931 door Dr. J. C. Koch als volwassen vogel; 7 Mei 1932 teruggevangen en weer losgelaten op dezelfde plaats. Berichtgever Dr. J. C. Koch, den Haag.\nSchollevaar [Phalacrocorax carbo subcormoranus (Brehm)].

    Description: In der kleinen, aber artenreichen Brachiopoden-Sammlung des RijksMuseum van Natuurlijke Historie in Leiden, die keine neuen Formen umfasst, sind die wichtigsten Genera der recenten Brachiopoden-Fauna vertreten.\nAm reichhaltigsten ist die Sammlung in bezug auf die Ordnung der Telotremata Beecher u. z. der Superfam. Terebratulacea Waagen und von dieser sind besonders zahlreich die Sub-Familien der Dallininae und Magellaniinae vertreten. Von den meisten Arten liegen nur einzelne Exemplare, reichhaltiges Material nur von Lingula unguis Linn. aus dem malayischen Archipel vor. Viele Exemplare stammen von der Fundstelle des Typen-Exemplares. Einige Exemplare sind bemerkenswert dadurch, dass sie durch von SIEBOLD (Japan), CUMING (Peru, St. Helena, Lord Hoods Insel), KRAUUS (Natal), QUOY und GAIMARD (Nouv. Holiande) und Sowerby (England) gesammelt wurden.\nDas interessanteste St\xc3\xbcck der Sammlung ist ein gut erhaltenes Exemplar von Trigonosemus pectiniformis (VON BUCH), das am Strande von Katwijk-Wassenaar zwischen recenten angesp\xc3\xbclten Molluscenschalen im Sande gefunden wurde, eine Form, die bisher nur fossil, besonders aus dem Senon von Maastricht bekannt ist und oberhalb der Kreide bisher nicht nachgewiesen wurde.\nDie Bestimmung mancher Exemplare, besonders vieler Trockenexemplare, war wegen des Fehlens des Armger\xc3\xbcstes und bei dem Mangel an Vergleichsmaterial sehr schwierig, in einigen F\xc3\xa4llen kaum mit einiger Sicherheit durchf\xc3\xbchrbar.

    Description: In 1914 the moldavites, australites and billitonites had already been known for many years and the queenstownites had just been discovered and recognised as tektites. In this year A. Eppler communicated that he had received a sphere of obsidian, \xc2\xb1 17 mm in diameter from South America, the place of origin not being known. Both according to his opinion and to that of Professor Weinschenk, it should be ascribed to the tektites. He arrived at this conclusion mainly by the external appearance of the pebble, that showed the same sculpture and lustre as that of most tektites. Otherwise, however, it had a marked resemblance to the terrestrial obsidian. Eppler compared his tektite to South American obsidians and found them to possess the same brownish grey colour in transmitted light, the same refractive index and practically the same specific gravity (the tektite 2.352, the obsidian 2.346).\nIn 1921 Lleras described similar spheres of glass from Columbia; he also considered them to be tektites. Later, however, (1925) in a detailed publication he defended the view of a terrestrial, volcanic origin of these rocks. After the appearance of Stutzer\xe2\x80\x99s paper Lleras (1929) was again converted to the opinion, that they were tektites.

Im Nachfolgenden sind die Pteridophyten erw\xc3\xa4hnt. Von dem Material, welches Eigentum des Reichsherbars zu Leiden ist, wurde ein Teil schon von Dr. ROSENSTOCK und weitaus der gr\xc3\xb6sste Teil des \xc3\xbcbrigen Materials von Dr. HALLIER bestimmt. Das gesamte Material wurde im Nachjar 1931 von mir revidiert, wobei der Rest bestimmt und einige fr\xc3\xbchere Bestimmungen ge\xc3\xa4ndert wurden. Es muss jedoch ausdr\xc3\xbccklich betont werden, dass der gr\xc3\xb6sste Teil schon von den obengenannten Forschern richtig bestimmt dalag.\nDie Anordnung der Genera und die Nomenklatur ist nach C. CHRISTENSEN, Index Filicum. Nur in einigen F\xc3\xa4llen ist nach der hiesigen Stand der Forschung davon abgewichen. Die Farne von den kleinen Sunda-Inseln und von S\xc3\xbcd Celebes mit benachbarten Inseln sind gesondert behandelt.

    Description: In dieser Arbeit gebe ich den zweiten Teil einer Revision der niederl\xc3\xa4ndischen Heterobasidiomyceten und Homobasidiomyceten -Aphyllophoraceen. Der erste Teil, der in holl\xc3\xa4ndischer Sprache erschien (Mededeelingen Nederl. Myc. Vereeniging Bd. 18\xe2\x80\x9420, 1931), war in Anlage und Behandlung k\xc3\xbcrzer gehalten. Auch diesmal beruht die Bearbeitung auf denselben Sammlungen, wie die Revision usw. von Oudemans und die darauf folgenden Ver\xc3\xb6ffentlichungen haupts\xc3\xa4chlich von der Hand von Frl. C. Cool in den Mededeelingen van de Nederlandsche Mycologische Vereeniging. Es stellte sich n\xc3\xa4mlich heraus, dass ein grosser Teil des Materials, auf dem diese Arbeiten basieren, in mehr oder weniger gutem Zustande erhalten geblieben war. Ausserdem habe ich selber im Laufe der Jahre, in denen ich mich mit den oben genannten Gruppen besch\xc3\xa4ftigte, ein Herbarium zusammengestellt, in dem die in diesem Teile behandelten Arten mit etwa 2000 europ\xc3\xa4ischen Nummern vertreten sind.\nMan kann mir vorwerfen, dass ich Zitate aus der holl\xc3\xa4ndischen Literatur \xc3\xbcber das vorliegende Gebiet weitgehend vernachl\xc3\xa4ssigt habe; doch hat dies seine guten Gr\xc3\xbcnde, denn eine Verbesserung aller Bestimmungen meiner Vorg\xc3\xa4nger und ein Eingehen auf alle ihre Ver\xc3\xb6ffentlichungen h\xc3\xa4tte viel mehr, meines Erachtens \xc3\xbcberfl\xc3\xbcssigen, Platz erfordert. Durch genauere Fundortangabe des untersuchten Materials und im Falle der Herbaria, auf denen Oudeman\xe2\x80\x99s Revision beruhte, auch der abweichenden, urspr\xc3\xbcnglichen Determination, habe ich diesem Uebelstande weitgehend abhelfen wollen. Wenn es erforderlich schien, wurde auch bei rezenteren Funden die urspr\xc3\xbcngliche Bestimmung angegeben.

    Description: Als ich im Jahre 1930 in der Lage war, auf Java etc. zu sammeln, richtete ich im Anfang meine besondere Aufmerksamkeit auf die epiphyllen Lejeuneen. Obwohl \xe2\x80\x9ede Frullaniaceis VII\xe2\x80\x9d damals eben ver\xc3\xb6ffentlicht war, sammelte ich auch viele Frullanien, in der Hoffnung noch \xe2\x80\x9eetwas Neues\xe2\x80\x9d zu finden. Studien an meinen frischen Aufsammlungen in Tjibodas, Buitenzorg und Bandoeng und besonders in den G\xc3\xa4rten etc. in Tjibodas und Buitenzorg zeigten mir den zweifelhaften Wert mancher kleinerer Sippen aus \xe2\x80\x9ede Frullaniaceis VII\xe2\x80\x9d. Es ist ohne weiteres klar, dass die meisten Frullanien in recht verschiedenen Modifikationen auftreten k\xc3\xb6nnen. Andererseits konnte ich auch zweifelsfrei feststellen, dass es sich bei manchen Arten um Komplexe von erblich verschiedenen Sippen handelt, die in manchen F\xc3\xa4llen durch ziemlich einfache Experimente wohl zu trennen sind. Die kurze Zeit, welche ich damals in Tjibodas verbringen konnte, erm\xc3\xb6glichte nur einige vorl\xc3\xa4ufige Versuche, welche mir aber die feste \xc3\x9cberzeugung gegeben haben, dass Experimente uns N\xc3\xa4heres \xc3\xbcber manche polymorphe Sippen lehren k\xc3\xb6nnen. Es w\xc3\xa4re nicht so schwierig, die wichtigsten Modifikationen und erbliche Abweichungen bei manchen Arten zu studieren. Ich glaube aber nicht, dass wir hier, wo es sich durchweg um Epiphyten handelt, solche klare Ergebnisse erwarten k\xc3\xb6nnen, wie Buch sie bei seinen klassischen Scapania-Experimenten erzielte. Mit schizostipen Lejeuneen sind diese Versuche viel schwieriger. Die Holostipae schliessen sich aber in vielen Hinsichten an die Frullanien an, und so entschloss ich mich, in Zukunft besonders die Revision und Bearbeitung von Frullanien und holostipen Lejeuneen in die Hand zu nehmen, in der Hoffnung, dabei selber einen Teil der notwendigsten Experimente anstellen zu k\xc3\xb6nnen! Gl\xc3\xbccklicherweise haben auch meine und die Schiff ner\xe2\x80\x99sehen Schizostipae einen Bearbeiter gefunden.\nSeit dem Erscheinen von \xe2\x80\x9ede Frullaniaceis VIII\xe2\x80\x9d habe ich mir stets Rechenschaft abgelegt, welche Probleme im Herbar und welche experimentell zu l\xc3\xb6sen sind. Ich halte es f\xc3\xbcr den gr\xc3\xb6ssten Fehler der modernen bryologischen Systematik, dass man imallgemeinen Zu sehr danach strebt, L\xc3\xb6sungen, welche erst in sp\xc3\xa4teren Dezennien experimentell zu erzielen sind, nun schon arbitrarisch nach dem Studium von Herbarmaterial zu diktieren. Es muss uns v\xc3\xb6llig gleichg\xc3\xbcltig sein, ob bestimmte L\xc3\xb6sungen vielleicht erst in einem folgenden Jahrhundert experimentell zu erreichen sind. Der im Herbar arbeitende Taxonom ist fertig, wenn er das Problem, das sp\xc3\xa4ter experimentell zu l\xc3\xb6sen ist, klar umschrieben hat. Hat er die Fragestellung vollst\xc3\xa4ndig angegeben, so muss er entweder mit Experimenten oder mit Revisionen anderer Gruppen anfangen.

Kopstein dem \xe2\x80\x9eRijks Museum van Nat. Historie te Leiden" geschenkt; die Typen des Materials vom \xe2\x80\x9eZoologisch Museum Buitenzorg" befinden sich ebenfalls in Leiden).\nEs liegen nur Uropygi vor, und zwar sind s\xc3\xa4mtliche Tiere Thelyphonidae.\nDas Material besteht aus 87 Exemplaren, gesammelt auf: Java, Borneo, Ambon, Haroekoe, Soela-Inseln, Flores, Noesa Laoet, Krakatau, KarimonDjawa Inseln.\nObwohl eine Anzahl Inseln, wo schon Pedipalpi gefangen wurden, fehlt (z.B. Sumatra, Celebes, Billiton, Madoera), ist dieser Erfolg doch sehr wichtig, weil auf nicht weniger als 5 der obengenannten 9 Inseln bisher noch keine Pedipalpen gesammelt wurden und zwar noch nicht auf: Haroekoe, Soela-Inseln, Plores, Noesa Laoet und Karimon-Djawa Inseln.\nDieses ist an sich schon ein sehr merklicher Erfolg, der wohl noch wichtiger erscheint, wenn wir in Betracht ziehen, dass sich unter diesen 87 Exemplaren 6 neue Arten und eine bis jetzt unbekannte Varietat befinden.\nUnsere Kenntnis der Verbreitung der Thelyphoniden ist immer noch eine ziemlich unvollst\xc3\xa4ndige, z.B. auf Ceram, \xe2\x80\x94 das viel grosser ist als die anderen Inseln der Molukken, \xe2\x80\x94 sind noch keine Thelyphoniden gesammelt worden.\nTHELYPHONUS Latr., em.

    Description: Voor dengene, die de studie der ratten in Nederlandsch-Indie thans ter hand zou willen nemen, zou het zeer zeker uiterst bezwaarlijk zijn, zich met betrekking tot de nomenclatuur dezer knaagdieren te orienteeren; als onmiddellijk gevolg eener onjuiste determinatie eenerzijds en een lichtvaardig beschrijven van nieuwe ondersoorten anderzijds is namelijk in den loop der laatste 15 jaren een zoodanige verwarring in de Indische rattenamen ontstaan, dat er ongetwijfeld dringend behoefte bestaat aan een wegwijzer op dit gebied, zoodat men oogenblikkelijk weet, welke rat in casu wordt bedoeld. In de volgende ljjst nu vindt men niet alleen een overzicht aangegeven van de namen der Indische ratten, zooals deze voortaan behooren te luiden, doch tevens de verschillende namen, waaronder zij tot dusverre te boek hebben gestaan; terwille der duidelijkheid is de volgorde der ratten in deze hjst geheel overeenkomstig die der betreffende publicatie van Sody 1) gekozen. 1. Rattus rattus diardi Jentink (1880), huisrat. In de zoologische literatuur tot 1918 komt zij voor onder den naam van R. r. griseiventer Bonhote, terwijl zij in de medische literatuur zelfs thans nog deze foutieve benaming draagt! 2. R. r. brevicaudatus Horst en de Raadt (1918), veldrat. In de zoologische literatuur tot 1918 komt zij voor onder den naam van R. r. diardi Jentink, welke naam men ook thans nog in de medische literatuur tegenkomt. 3. R. r. alexandrinus rufescens de Raadt (1931), boomrat 1). Synoniemen hiervan zijn achtereenvolgens: a. R. r. rufescens Gray.

    Description: In einer kleinen Sammlung Scyphomedusen von Amoy, China, die mir von Kapt. A. K. TOTTON vom British Museum (Natural-History), London, zur Bestimmung eingesendet wurde, fand sich ein Exemplar einer RhopilemaSpecies, das mir sofort durch seinen Habitus auffiel. Es zeigte wohl das typische Verhalten des f\xc3\xbcr dieses Genus so charakteristischen Gef\xc3\xa4ssystems mit dem breiten feinmaschigen Anastomosennetz und der ebenfalls zartmaschigen Netzarkade, doch waren die Mundarme anders gebaut, wie es bei diesem Genus sonst der Fall ist. Sie waren auffallend schlank und trugen einen langen kr\xc3\xa4ftigen Endkolben, ein Verhalten, wie es dem Genus Rhizostoma eigent\xc3\xbcmlich ist.\nBei genauerer Untersuchung des Exemplares ergab sich, dass dasselbe der Beschreibung Haeckels von Rhopilema rhopalophora aus dem Indischen Ocean, \xc3\xb6stl. von Madagascar, sehr nahe kommt (2, p. 596). Da seit der Beschreibung des Typen-Exemplares keinerlei genauere Angaben \xc3\xbcber diese Species in der Litteratur vorkommen, die Haeckel\'sche Diagnose sehr kurz und von keiner Abbildung begleitet ist und die Art als unsicher betrachtet wird, will ich das vorliegende Exemplar n\xc3\xa4her beschreiben, umsomehr, weil ich jetzt geneigt bin, die Haeckel\'sche Art aufrecht zu halten.\nNach Haeckel\'s Angaben sind f\xc3\xbcr die Species rhopalophora charakteristisch: eine grosse Zahl von Randl\xc3\xa4ppchen (16 per Oktant), zahlreiche herabh\xc3\xa4ngende Krystallkn\xc3\xb6pfe an den Seiten und am Ende jedes Mundarmes ein grosser dreikantig-prismatischer an beiden Enden zugespitzter Gallertknopf, der so lang ist wie der ganze Unterarm. Fundort: Madagascar.\nVanhoeffen (8, p. 33) h\xc3\xa4lt diese Species auf Grund der genannten

    Description: In 1903 beschreef Bonhote 1) onder den naam van Mus bukit een rat, afkomstig van het Maleische schiereiland (Jalor); aangezien nu deze R. bukit ook op Java voorkornt en in de Indische literatuur eertijds onder den naam van R. jerdoni Blyth te boek stond, is het zeer zeker de moeite waard eens na te gaan, op welke wijze de naam bukit ontstaan is; men kan nu bij Hossack 2) het volgende hierover vinden, hij schrijft (blz. 4): \xe2\x80\x9eMr. Bonhote admits that a series of M. bukit agreed exactly with a series sent home by Mr. Lyle from Assam and recorded by Mr. Bonhote himself as M. jerdoni. Nevertheless, not only does he retain the name of M. bukit, but he places it in a different subgroup from M. jerdoni, namely, that of M. griseiventer 1). M. pellax is practically a prototype of M. jerdoni, but he separates them".\nZiedaar nu de zeer zonderlinge en allesbehalve wetenschappelijke wijze, waarop door Bonhote deze zoogenaamde Mus bukit van de Mus jerdoni is afgescheiden; desniettemin heeft hij, zooals uit de literatuur blijkt, met deze afscheiding nog zoo\'n bijval geoogst, dat sindsdien de R. bukit op Java zelfs in 2 subspecies is onderverdeeld2), terwijl tevens de naam R. jerdoni Blyth geheel uit de Indische literatuur is verdwenen! Het is dan ook, meen ik, thans wel heel duidelijk, dat er hoegenaamd niet het minste verschil bestaat tusschen R. bukit en R. jerdoni en dat derhalve de tegenwoordig gangbare namen R. bukit treubi en R. bukit temmincki van stonde af aan plaats zullen moeten maken voor den vroeger bestaanden naam van de bewuste rat, n.l. R. jerdoni Blyth.\nLITERATUUR. 1. Bonhote, Geciteerd naar Hossack.

    Description: On September 21st last Professor Dr. E. D. van Oort died at Leiden rather suddenly. For a considerable time his health had, indeed, been indifferent; on frequent occasions he had been unwell for shorter or longer periods, and in the spring of this year he was even obliged to apply for a four months\' leave of absence. When after the expiry of this period, apparently recovered, he resumed his work, be it only for a few hours daily, we fostered the hope to have him among us for many years to come. Fate, however, decided differently. On Thursday morning he came to the museum, feeling better than on the previous days; he received the visitors cheerfully, and left the building past noon. Three hours later death had overtaken him.\nEduard Daniel van Oort was born at Barneveld on October 31st, 1876. Already in early boyhood he felt drawn to nature, and spent a great part of his leisure-hours, nay even occasionally of his schoolhours, in the open, watching the animals, and especially the birds, in their natural surroundings.\nHis teacher in biology at the Secondary School at the Hague, the late Dr. Ed. Everts, the well-known coleopterist, stimulated his love to the animal world, leading it into the right channels and assisting him with advice and help in forming his collections. This once roused interest determined his career. In 1895 he went to the University at Leiden, where he studied botany and under Professor Hoffmann zoology. Afterwards he was for some years (1900\xc3\xa2\xc2\x80\xc2\x941904) assistant of Professor K.\nMartin, director of the "Rijks Geologisch-mineralogisch Museum" (National Geological and Mineralogical Museum).

    Description: Gelegentlich der Durchsicht einiger \xc3\xa4lterer Planktonf\xc3\xa4nge aus dem malayischen Archipel in den Sammlungen des Rijks Museum van Natuurlijke Historie in Leiden fanden sich zahlreiche Entwicklungsstadien von Rhopilema hispidum (VANH.) MAAS vor, \xc3\xbcber die ich hier kurz berichten will. Ueber die Entwicklung des Genus Rhopilema ist bisher nichts bekannt. Dies ist auffallend, weil dasselbe in den japanischen, indischen und malayischen Gew\xc3\xa4ssern durch einige Arten vertreten ist und dieselben keineswegs zu den seltenen Formen gerechnet werden k\xc3\xb6nnen. In Japan wird Rhopilema esculentum KISH. sogar als Volks-Nahrungsmittel verwendet (3), Rh. hispidum MAAS ist in den Sammlungen des Rijksmuseum durch zahlreiche Exemplare von verschiedenen Fundorten aus dem malayischen Archipel vertreten (5, 6).\nDa die Entwicklung der beiden anderen Scapulaten-Genera Rhizostoma und Stomolophus wenigstens einigermassen bekannt ist, \xc3\xbcber die von Rhopilema \xc3\xbcberhaupt noch keine Angaben vorliegen, ist die Auffindung einiger Entwicklungsstadien der letzteren von Interesse. Es ergab sich sofort die Frage, ob sich in der Entwicklung des Gastrovascularsystems von Rhopilema auch eine Reihe aufeinanderfolgender Stadien w\xc3\xbcrde feststellen lassen, wie dies bei den Genera Rhizostoma und Stomolophus der Fall war. Eine solche ist auch hier nachweisbar. Bei der nahen Verwandschaft zwischen den Genera Rhizostoma und Rhopilema war \xc3\xbcbrigens zu erwarten, dass es keine grossen Ueberraschungen geben w\xc3\xbcrde.\nEs liegt folgendes Material von Rhopilema hispidum vor: N\xc2\xb0. 321 21 Ex.

    Description: The radium content of twenty-eight (twenty-seven from the Pacific) samples of ocean-bottom sediments was determined, and similar determinations reported by Joly and Pettersson are included for comparison. These comprise practically all such determinations that have been made, and the paucity of these data in comparison to the extent, importance, and high radium content of the material is emphasized. Those bottoms composed mostly or entirely of red clay generally contain more radium. A mechanism for explaining the high radium content of deep-sea sediments is suggested which does not coincide with the opinions of either Joly or Pettersson.
