| La Tanche, navire de recherches de l'Office Scientifique et Technique des Pêches Maritimes, armée par un équipage de la Marine Nationale et placée sous l'autorité du commandant Le Guen, pilote-major, appareille de Lorient le 10 août 1927, pour une croisière d'études dans le golfe entre la côte nord d'Espagne et l'Irlande. Un appareil nouveau de sondage par le son a été installé à bord de la Tanche par son inventeur, M. l'ingénieur hydrographe P. Marti, et réglé au cours d'une sortie d'essai, les 6 et 7 août. La direction de la croisière est confiée à M. Belloc, chef du laboratoire de l'Office à La Rochelle ; assisté de M. Olivier, préparateur au même laboratoire. M. Miquel est embarqué, comme l'année précédente, en qualité de maître de pêche. [OCR NON... |

| Our Pinus halepensis is described by DUHAMEL DU MONCEAU in „Traité des arbres et arbustes etc.” 1755 p. 126 as follows: Pinus Hierosolymitana praelongis et tenuissimis viridibus foliis PLUK.: Pin de Jerusalem, dont les feuilles sont très vertes, longues et menues. This circumscription is a phrase without a trivial name. LINNAEUS himself also indicated the species in that period principally by a phrase; a trivial name („nomen triviale”) was added in 1753 for convenience; but LINNAEUS warns emphatically against forgetting the art-name (that is the phrase, „differentia specifica” or „nomen spicificum” of LINNAEUS) ¹). This art-name (phrase) was arranged methodically by him and bad to be such, that there was to be found in it exactly what was wanted to... |

| During his second Karakoram expedition in 1925 Mr. Ph. C. Visser collected some 70 rock specimens from the valley of the Hunza and its tributaries. The following is a petrographic description of these specimens and I gladly take this opportunity of thanking Mr. Visser for entrusting me with his valuable material. Geologists are much endebted to this energetic explorer for bringing together such a considerable number of samples under circumstances in which all carriage had to be reduced to a minimum and when so many other calls were being made on his time and energy. A collection made by a layman and therefore taken without many observations on mode of occurrence, must naturally be of limited value. When, however, it concerns a region that is almost terra... |

| Only one eruption of the island Una-Una (Gulf of Tomini, Northern Celebes), in 1898, has been recorded in historical time; it was described in 1902 by Wichmann (l. c.) after data gathered from different witnesses. No lava flowed out, it was an ash-eruption. During that eruption large mud streams, called lahars, descended along the slope of the volcano and some broad flat-bottomed valleys were eroded (Pl. 44, fig. 4) which are known so very well from some Javanese volcanoes, especially from Mount Kelut. With the latter Una-Una shows many points of resemblance, in shape, structure and in type of the latest eruption. Along one of the large typical lahar valleys we climbed the volcanoe starting near Kololio. Fig. 6 and 7 show the higher parts of our road,... |

| Op een levend voorwerp van Varanus komodoensis Ouwens in de verzameling van het Genootschap Natura Artis Magistra te Amsterdam werden in October 1926 eenige Aponomma's gevonden, die mij ter onderzoek toegezonden werden. Deze behooren tot eene nog onbeschrevene soort, van welke ik hierna de beschrijving volgen laat. In het geheel werden een 35-tal exemplaren, alle ♂ ♂, gevonden, die zich in het Zoölogisch Museum te Amsterdam, alsmede in 's Rijks Museum van Natuurlijke Historie te Leiden bevinden. Als gewoonlijk, zaten de teken met een klein gedeelte van de voorste helft onder den vrijen achterrand der schubben verscholen. De nieuwe soort blijkt aan Aponomma auratus (Shaw 1793) (gervaisi Lucas 1847) naverwant te zijn. Maten. Het afgebeelde individu was er... |

| It is well known that before the famous eruption of August 1883 took place, the island Krakatoa consisted of three volcanoes, the basaltic volcano Rakata and the andesitic volcanoes Danan and Perbuwatan. With the great explosion of August 28th of that year Danan, Perbuwatan and the northwestern part of Rakata were entirely destroyed. Since then a coral reef began to grow on the Northwestern slope of the Rakata ruïn at a spot called Black Point (Zwarte Hoek), a place where the basaltic lava of Krakatoa is exposed. |

| The different theories concerning the origin of Salt Domes in Roumania, Germany, Texas, Louisiana, Colorado and Utah are discussed. In Roumania the salt occurs in cores of “Diapir” anticlines. The existance of hills of salt indicates, that the salt is still pushing upwards. In Germany the salt district shows slight folding but the salt itself is intensively folded. The theory of Lachmann-Arrhenius-Harbort explains the salt domes by isostasy combined with a lower specific gravity and greater plasticity of the salt than of the covering layers. This theory is opposed by Stille, who accounts for the salt domes by mesozoic folding. The latter theory has apparently gained preference in America for the explanation of the Salt Domes in Texas and Louisiana,... |

| Die Versteinerung, welche der nachfolgenden Untersuchung zu Grunde liegt, stammt aus den Unter-Palembangschichten von Pangadang, welches 25 km westlich von Sekajoe gelegen ist, in der Res. Palembang des südlichen Sumatra. Sie befand sich etwa 500 m unterhalb der oberen Grenze dieser Formation und war in einem Tonknollen eingeschlossen, welcher aufgeschlagen die beiderseitigen Abdrücke und den grössten Teil des zugehörigen Steinkerns lieferte. Herr I. M. Kampmeinert, Geologe der „Bataafsche Petroleum Maatschappij”, entdeckte das Objekt und die genannte Gesellschaft überliess es mir zur Bearbeitung, wofür ich ihr verbindlichst danke. Durch freundlich erteilte Auskunft verpflichtete mich Herr Prof. Dr. Ernst Freiherr Stromer von Reichenbach; für die... |

| Von Herrn G. I. H. Molengraaff erhielt das Leidener Museum eine Reihe interessanter Korallen aus den Rudistenkalken von Curaçao, und Herr Ch. Weaver, in Seattle, überliess mir die von ihm auf seinen Reisen in den argentinischen Kordilleren gesammelten Korallen zur Bearbeitung. Ferner befand sich in der Sammlung K. Martin des hiesigen Museums noch ein Kalkstück von Curaçao mit einer Koralle, das zwar von Martin bereits erwähnt, aber noch nicht näher untersucht worden war. Schliesslich nehme ich die Gelegenheit wahr, um einige mir vor längerer Zeit von den Herren Steinmann und Windhausen übergebene Stücke zu beschreiben, so wie die Beschreibung einer von mir selbst in der argentinischen Kordillere gesammelten Koralle hier noch nachzuholen. Den oben genannten... |

| In the paper on the Rhizocephala of the Siboga Expedition ( VAN KAMPEN and BOSCHMA 1925) besides the material collected during this expedition a number of specimens from other collections have been described. Among these there were a few from the collection of the Leiden Museum ('s Rijks Museum van Natuurlijke Historie). The rich collection of Crustacea in this Museum, however, contains a much larger number of specimens infested with Rhizocephala than those described in the cited paper, as turned out after an inspection of the whole collection. Alltogether 35 specimens, including the 10 specimens described in the cited paper, could be found. The taxonomy of the Rhizocephala is a rather difficult problem, which can be solved only after the study of a... |

| Die kleine Sammlung von Hydromedusen aus dem malayischen Archipel, die sich im Besitze des Rijks Museum van Natuurlijke Historie in Leiden befindet, umfasst ca 400 Exemplare. Das Material stammt fast durchwegs aus der Java-See (Nordküste von Java, Semarang, Cheribon, Pekalungan), einige Exemplare sind von Singapore, und wurde in den Jahren 1905—1916 hauptsächlich durch P. BUITENDIJK, zum geringen Teile durch K. HAASNOOT gesammelt. Es handelt sich hier fast ausschliesslich um Küstenformen. Die Sammlung enthält nur 1 Anthomedusen- und 1 Narcomedusenart, dagegen sind die Leptomedusen u. z. die Familien der Eucopidae und die Aequoridae ziemlich reichlich, die erstere mit 6, die letztere mit 4 verschiedenen Formen vertreten. Trachomedusen fehlen ganz. Die... |

| Wanneer wij de litteratuur over de in Nederland voorkomende Mollusca nagaan, vinden wij als laatste samenvattende publicaties de beide lijsten van het Mollusken-Comité. In de nieuwste (1927) valt ons onder meer het volgende op: „Niet altijd is de nomenclatuur geheel volgens de laatste eischen der prioriteit". Dit is inderdaad waar, en ik zal trachten met het onderstaande hierin zooveel mogelijk te voorzien. Bij de meeste hieronder genoemde soorten volgen vindplaatsen. Ik heb alleen die vindplaatsen vermeld, die in bovengenoemde lijst niet voorkomen, daar dit stukje uitsluitend als aanvulling is bedoeld. Hoewel ik ervan overtuigd ben nog lang niet volledig te zijn, neem ik aan, dat deze lijst een juisteren indruk zal geven van de verspreiding van onze... |

| The influence of the wind laden with sand in modelling pebbles is believed by some authors to be only that of polishing the surface, by others of rounding off bits of stone that already possessed edges and corners, or again by others of wearing any fragment either rounded or angular into definite forms with ridges and facets, dependent on the shape of the basis (Alb. Heim). Experiments, fully confirming the last opinion, are described in this paper: no rounding off took place, while the models were slowly revolved in the sandblast, and vertical planes took on a backward slanting position, cutting eachother along sharp edges. Where sand corrosion is great, as in the desert, the windworn pebbles owe their shape to the laws formulated by Heim; many of the... |

| In two previous publications (bibl. 1 and 2) I have brought the formation of calderas into relation with the gas phase, observed by Perret during the eruption of Vesuvius in 1906 (bibl. 3). In these papers I arrived at the conclusion that during the gas phase a cylinder is cored out, and that this may be the cause of caldera formation. In the first paper the subject was treated geometrically, while in the second calculations were made of a particular case (the Krakatoa eruption of 1883) to see if they would bear out this theory. This caldera-formation, however, is not a typical case, as there must previously have been an older Krakatoa-caldera, and in Aug. 1883 it was not a large portion of the volcanic cone that disappeared, but only an island which... |

| Le terrain exploré fait partie du prolongement vers l’est de la zone des Alpes bergamasques que Cosijn et Jong ont commencé à mettre en carte en 1926 (fig. 1). Il comprend des parties du cristallin situé au nord de la „ligne orobique”, du paquet d’écaillés (série porphyrique, série Collio, Verrucano, partie du Servino) et du paquet charrié consistant en Muschelkalk et en Esino (Muschelkalk, Esino, Esino supérieur, Raibl inférieur, c. à. d. „Raibler Plattenkalk”). Le plancher du Muschelkalk et de l’Esino se trouve dans les couches du Servino qui servent de moyen de glissement. Ce Servino de la zone de charriage apparaît à la surface au nord et au nord-est du Passo San Simone. Le substratum des paquets sédimentaires consiste en la même substance que le... |
