| Die Königlich Zoologische Gesellschaft „Natura Artis Magistra”, deren Hundertjahrfeier wir diesen Sommer feiern, hat sich von Anfang an die Aufgabe gestellt, mehr als die Eigentümerin eines Gartens zu sein, in welchem mehr oder weniger seltene und kuriose Tiere für das Publikum zur Schau gestellt sind, und hat immer danach gestrebt, ein kulturelles und wissenschaftliches Zentrum in der Stadt ihrer Gründung darzustellen. Das Glück wahr ihr dabei hold: gelegen in der Mitte einer grossen, aber nicht zu grossen Stadt, gross genug, als Reichshaupt- und Universitätsstadt ein Kultur-Mittelpunkt des Landes zu sein, und andererseits doch wieder nicht so gross, dass dabei die einzelnen Institute im Ganzen verlorengehen, vermochte sie sich je länger je mehr mit... |

| The history of the European bison gives us a most striking example how some species of animals disappear gradually while being deprived of their natural surroundings. In Western Europe, where the increase of population and development of rural settlements showed a quicker progress than in the East of the continent, the bisons were regarded as Royal game already since the VII-th or VIII-th century and attemps have been made to protect them more or less. Nevertheless the area of the distribution of the bison shrank rapidly and at the beginning of the XIX-th century was restricted only to the Białowieza Forest. It should be added, however, that over 50 years ago the occurence of the bisons was discovered also at another place namely on the North-Western... |

| At the time when the Royal Zoological Society Natura Artis Magistra known in Holland as “Artis” was founded in 1838 the ground for the study of malacology lay already well prepared. For ever since the days when the early Dutch seafarers explored the commercial routes to East and to West, all kinds of curiosities and natural history objects found their way to the motherland, brought back by the homebound sailors. |

| As Prof. Bremekamp has dealt with the genus Pleiocraterium from the taxonomic point of view, I intend to supplement his exposition here with some observations on the ecology of these remarkable additions to the Malaysian mountain flora. Some of these observations have been included already in a general report on the results of the Losir expedition published in Dutch. As a further illustration I am giving two photographs taken from one of the two Sumatran species in its natural habitat. Altitude. Both species were found on the highest parts of the mountains only, viz. Pl. gentianifolium just below the summit of Mt Goh Lembuh, and Pl. sumatranum between our camp at the base of the central Peak of Mt Losir at c. 3250 m. and the summit of the latter at 3460 m.... |

| 1. The genus Atheroides Haliday Of this genus 3 Western European species are known : A. serrulatus Hal. (syn. festucae Mordv.?), A. hirtellus Hal. (syn. A. junci Laing) and A. brevicornis Laing. a) A. serrulatus Hal. is quite common. It lives on Poa annua often, but prefers species of grass with narrow, folded leaves, such as Festuca ovina, F. rubra, Nardus etc. b) A. hirtellus Hal. is not rare on Aira caespitosa. It seems to live on that plant only. c) A. brevicornis Laing is extremely common along the muddy seashores of the Netherlands. It prefers Festuca thalassica and F. distans, the two typical species of grass growing there 2). The alatae have not yet been described and therefore I add a short description. The apterae have been described excellently... |

| The observations made during the Carstensz Expedition give the following impression of the geological structure of the Nassau mountains: 1. Possibly Lower Palaeozoic, Upper Palaeozoic, Mesozoic and Tertiary (Tertiary c, d, e and f) rocks were found. 2. A granodioritic intrusion occurs with a contact zone rich in metasomatic hydrothermal ores (copper, gold). The age of this intrusion is Upper Tertiary, probably even younger than the folding of the mountains. 3. The simplest explanation of the tectonical structure is to assume that these mountains are a big overthrusted mass, moved towards the South over the continuation of the Australian continent. The upper parts (Tertiary) of this mass are folded; otherwise, only North dips were observed. 4. The foreland... |

| Wenn die Internationale Organisation der Direktoren der grossen, wissenschaftlich geleiteten Tiergärten ihre 50. Jahrestagung mit der Hundertjahr-Feier der Königlichen Zoologischen Gesellschaft Natura Artis Magistra in Amsterdam im Mai 1938 zusammenfallen lässt, so will sie damit bekunden, wie sehr verbunden sie sich mit dem alt-ehrwürdigen Amsterdamer Zoologischen Garten fühlt und wie hoch sie die Bedeutung dieses Instituts für die biologischen Wissenschaften und für das Kulturleben der Niederlande zu schätzen weiss. Das gemeinsame Jubiläum der beiden Organisationen scheint Anlass genug, in der Festschrift der „Artis” eine kurze Betrachtung über das Entstehen, den Zweck und die Ziele des massgebenden Tiergärtnerverbandes anzustellen. In den Jahrzehnten... |

| In de zomermaanden van de jaren 1936 en 1937 bewerkten wij het gebied van het Val di Scalve en het Val Nembo met als oostgrens de gebergtekam S. Fermo—Ezendola en als westgrens de Presolana—Ferrante-kam. In 1936 werkten W. A. Visser en H. C. A. Swolfs westelijk van ons gebied. De resultaten hiervan zijn reeds gepubliceerd. In 1937 werkte in het Noorden G. Zijlstra en in het Zuid-oosten L. Dorsman. In het Noordwesten grenst dit gebied aan het reeds door J. Weeda bewerkte Boven-Serio-dal en het is op zijn verzoek, dat wij ons onderzoek uitstrekten tot meer W. van Nona. |

| Der stratigraphische Aufbau der grossen Hochmoore in den Niederlanden, besonders derjenigen in den nördlichen Teilen des Landes, zeigt im allgemeinen die bekannte Zweiteilung des Hochmoortorflagers. Der ältere Hochmoortorf ist meist stark zersetzt. Neben Resten von Sphagnum werden auch solche von anderen Pflanzen, besonders von Eriophorum, darin gefunden. Nach oben geht dieses Torflager allmählich in den sogen. Grenztorf über. Dieser Grenztorf zeichnet sich meist durch einen grossen Reichtum an Eriophorum aus, während auch viele Heidereste darin enthalten sind. Ueber diesem Grenztorf folgt mit meist scharfem Uebergang der jüngere Hochmoortorf. Dieser ist meist ein fast reiner, wenig zersetzter Sphagnumtorf, worin grobblätterige Bleichmoosarten... |

| The present records are mainly based upon the collections by C. W. WANG in Yunnan, 1936. We are indebted to Dr E. D. MERRILL, Harvard University, Jamaica Plain, Mass., U.S.A., for putting these specimens to our disposal. Except for a few points, our views concerning the genus have not been essentially modified. The data mentioned are supplementary to those, published in our earlier paper: Revision of the Sarcospermataceae (Blumea 3, 1938, 183—200). |

| The earliest account of the Netherlands’ Algae appeared in 1781 in D. de Gorter, Flora VII Prov. Belgii foederati indigen. Here, however, in the Algae lichens and liverworts have been incorporated. The true Algae, of which 35 are enumerated, are principally marine, though also aërophytical and freshwater Algae are among them. Some fifty years later F. A. W. Miquel gave a revision of the Netherlands’ Algae, with keys and descriptions in Latin and Dutch, in van Hall, Flora Belgii septentrionalis. We find them in two tribes: 1. Algae Chloricae, to which belong the bluegreens, the diatoms, the green Algae, the Charophytes; and 2. Algae Chromicae, to which belong the brown and the red Algae. At that time about too species from this country were known, which had... |

| Nordamerikanischer Bison und europäischer Wisent sind miteinander verwandte Wildrinder (nicht Büffel, wie man oft sagen hört), die sehr wahrscheinlich einen gemeinsamen Vorfahren haben, doch sollen an dieser Stelle weder Ort noch Zeit der Aufspaltung, weder die mutmaasslichen Wanderwege der beiden Zweige, noch der Grad der Verwandtschaft näher erörtert werden. Wir haben heute beide als gute Arten vor uns, innerhalb welcher mehrere Rassen bezw. »Schläge erkennbar waren und z. T. noch sind. Aber diese Rassenunterschiede innerhalb der einzelnen Arten werden seit einigen Jahrzehnten mehr und mehr verwischt und dürften verschwinden oder durch neue, erbfest gewordene Formen abgelöst werden, wenn sich die Züchter nicht noch in letzter Stunde dazu entschliessen,... |

| In het insectarium van „Natura Artis Magistra” kweek ik reeds gedurende meerdere tientallen jaren achtereen zes soorten Phasmidae. Deze zijn Eurycnema herculeana BR., Dixippus morosus BR., Phyllium pulchrifolium SERV., Phyllium siccifolium L., Diapheromera femorata HARR. en Bacillus rossii F. Met uitzondering van Phyllium siccifolium, welke soort ik slechts enkele malen gekweekt heb ¹), zijn de overige vijf permanent in het insectarium vertegenwoordigd. Opmerkelijk is, dat uit de geïmporteerde eieren van Eurycnema herculeana steeds uitsluitend wijfjes komen. De volgende generaties van de te Amsterdam gekweekte exemplaren van deze soort bestaan uit mannetjes en wijfjes, en wel van beide geslachten ongeveer hetzelfde aantal. In Nederl. Oost-Indië schijnen de... |

| De in deze Jubileumserie van de „Mededeelingen van het Botanisch Museum en Herbarium te Utrecht” opgenomen artikelen zijn door de schrijvers ingezonden om Prof. Pulle, ter gelegenheid van zijn zilveren jubileum als hoogleeraar, hun waardeering te toonen. Een kort woord over den jubilaris moge hier als inleiding van deze bijdragen volgen. Op 10 Januari 1878, op den dag dat in verschillende plaatsen den Ioosten sterfdag van Linnaeus werd herdacht, werd August Adriaan Pulle te Arnhem geboren. |

| When in the summer of 1937 foot-and-mouth disease began to prevail among the cattle of Holland and spread rapidly in spite of extensive measures taken by the Dutch Veterinary Government Inspection, it was to be expected that also those animals in the Zoological Gardens, susceptible to this disease, would be affected. Experience gained during earlier extensive foot-and-mouth-disease epizooticae has proved that this disease, singularly contagious for ruminants, could not be prevented notwithstanding the secluded spot occupied by these animals in the Zoological Gardens. |

| More than 70 years have elapsed, since, in 1866, de Bary enunciated the hypothesis that Lichens are dual organisms, the socalled gonidia being Algae. As about 1899, the year when Nylander died, the dual nature of the Lichens had become generally accepted, lichenologists have had 40 years to realize the consequences of this theory. Nevertheless even now opinions differ widely. While practically all botanists admit that a Lichen is composed of a Fungus and an Alga, most lichen-taxonomists apply, perhaps for a good deal unintentionally, the species-name to the consortium, while others emphasize the necessity of restricting the specific and generic names to the Fungus. Reinke, Wainio, Zahlbruckner and Keissler may be regarded as adherents of the first... |

| Since the paper by Smith in 1894 (A list of the recent species of the genus Pirula) no monograph, review, or catalogue of the recent species of the genus Pirula has been published, as far as I am able to state. Besides the species of which our Museum possesses specimens, I have quoted again, as in my former catalogues, all the other species, as far as I could find these mentioned in literature, whilst I added the principal synonyms. After those species of which we possess material there follows a list of the specimens stating: 1) the letter which indicates specimens from the same locality and collector (donor), as far as they are kept dry; in the case of specimens preserved in spirit the number of the jar is given instead, 2) the number of specimens, 3)... |
