| Fam. ARICIIDAE. Aricia foetida Clap. Fundort: 73° N. 25° 0. 220 fm. 19.VII. 1878. -W. B. 1878/79. — M. L. Von diesem Fundort liegen zwei hinten mehr oder weniger unvollständige Exemplare vor, von denen das kürzere mit noch 95 Segmenten ca. 33 mm lang ist. Ich bemerke über dieses Tier folgendes. Die Kiemen beginnen am neunten Borstensegment. Die Thoraxregion umfasst ca. 25 Borstensegmente, vom ca. 26. Borstensegment an haben die Ventralparapodien die für die abdominale Region charakteristische Form. Bauchpapillen finden sich am 18. bis 26. Borstensegment, an dem letzten dieser Segmente nur noch in der Einzahl jederseits, im Maximum zu 10—12 jederseits. Zwischen den Parapodasten jeder Körperseite ist ein intermediärer Cirrus sicher vorhanden, ich konnte sein... |

| For the ecologist systematic units are actors in a play. Whatever their christian- and family-names may be — it is their role, whether master or servant, whether villain or hero — which determines the character of the performance. This performance has, moreover, the property of being both continuous and simultaneous: all scenes are given at once. Such a continuous and simultaneous performance is called a biocoenosis. In a great many ways, a biocoenosis reminds us of an organism. For the coördination between organs or tissues, or even cells is also continuous and simultaneous. A biocoenosis is a higher vital unit, and may be approached by the same methods which we use for the study of organisms (V. D. KLAAUW (24)). In the systematic approach we establish... |

| The "Catalogue illustré des Animaux marins comestibles, avec leurs noms communs français et étrangers" (Illustrated catalogue of edible marine animals, with their French and foreign names) (1), published in 1925 by MM. Joubin and Le Danois only included the species found on the French coasts and the surrounding seas. It seemed useful to complete this catalogue at a time when French trawlers extended their fishing areas to the South, all the way to Senegal. The main goal of the previous catalogue was to have the entire country adopting a single official name for each fish. We have to admit that this goal has not been reached and that, for example, the monkfish is still designated using thirty four different names, five of which are used for other completely... |

| As a result of my further work on the reordening of the collection of bugs in the Leiden Museum I am giving now a catalogue of the Coreidae in the Museum, which will appear in some parts, as the group is rather large. Again I was enabled to visit the British Museum (Natural History), and I will include in the present paper some remarks upon species of which types are in this Museum. Of course it was of great importance for the identification of our specimens too, that I could compare the doubtful things with the rich collection in this Museum. I am very thankful to Mr. China again for his kind assistance. Some years ago (in 1928) the Leiden Museum acquired the extensive collection of bugs of Mr. A. J. P. Fokker. This collection has to be kept separately... |

| Le salage, dans les industries de la pêche, prend une place dont il est sûrement inutile de souligner l'importance. Le laboratoire de chimie appliquée de l'Office des Pêches Maritimes se trouve naturellement amené à l'étude de différents problèmes relatifs à cette technique de traitement du poisson. Déjà, dans un précédent fascicule de la présente Revue (1), sont relatés les résultats de recherches, de nature à la fois chimique et bactériologique, sur les phénomènes susceptibles de donner à la morue salée une teinte jaune plus ou moins accentuée et un aspect déplaisant pour le consommateur. Nous allons, maintenant, poursuivre notre contribution à l'étude du salage en traitant de deux autres questions : le rouge de la morue ; le salage du hareng. [OCR NON... |

| In my revision of the Rubiaceae in Pulle’s Flora of Surinam two genera, viz. Pagamea and Perama, which are now usually included in this family, are relegated to an appendix. On account of its superior ovary Pagamea was formerly reckoned to the Loganiaceae, from where it was referred to the Rubiaceae by Baillon and K. Schumann, who were of opinion that its solitary ascending ovules, and the valvate aestivation of the corolla lobes assigned it a place among the Psychotrieae. I think however that they overestimated the value of these characters, which are of a rather general nature, and that Pagamea both in the structure of its inflorescence and in that of its flowers shows so little resemblance to the Psychotrieae that it is impossible to include it in this... |

| A complete account of all the reptiles then known to occur in the Indo-Australian Archipelago was published by De Rooij in 1915 and 1917. Since this time several new species have been described, while others have been suppressed or revived. Also the problem of geographical variation begins to penetrate in herpetology more and more. While studying the herpetological collections of the Rijksmuseum van Natuurlijke Historie, Leiden and the Zoological Museum, Amsterdam, it became clear to me that, though De Rooij's books offer a sound basis for further studies on the reptiles of the Indo-Australian Archipelago, a great deal of revisional work must still be done before our knowledge of the herpetological fauna of that region will be fairly complete. As I can... |

| After Mr. S. BLOEMBERGEN had planned a revision of the Cornaceae, sensu amplissimo, of the Netherlands Indies (inclusive those of the Malay Peninsula and the non-Dutch parts of Borneo and New Guinea) and had received, for that purpose, herbarium materials from different institutes, it appeared desirable to him to confine his revision to the Alangiaceae. I therefore took the Cornaceae, sensu stricto, for my account. It was very convenient to me that Mr. BLOEMBERGEN had already composed a nearly complete list of literature wanted. The herbaria of which materials have been worked up in this revision, arE the following. B = Herbarium of the Botanic Garden, Buitenzorg, Java. Be = Herbarium of the Botanic Garden, Berlin—Dahlem. L = State Herbarium, Leiden. S =... |

| During the year of 1928, in the scientifico-technique station of the Institute for the Study of the Northern Seas in Portchnik, we carried out a number of observations on the cod and haddock longline fisheries. The fish was provided by some fishermen from the camps of Zakhrebetnaïa and Chelpino. We used to study all the fishes caught in one day (i.e. one longline drop) by one fishermen tarel (community) or the other. Each cod or haddock specimen was measured with a tape (in centimetres), weighed with a decimal scale and opened in order to determine its gender and to examine the state of its sexual products. Moreover, we studied separately each specimen's liver and collected some materials on a few specimens in order to determine their age (scales, otolith,... |

| A phylogenetic system resulting from comparative morphological studies claims to be the expression of evolution. The character of any phylogenetic classification based on morphological studies exclusively is a speculative one. The fragmental facts procured by fossil relicts from earlier geological periods are also morphological and allow only the conclusion that evolution took place, but in which way changes evolved has not been stated by immediate observation. Nobody escapes from the idea that all living beings existing yet, have originated from those in the past. It is undeniable that the vegetation which covered the earth in former periods has been changed. This historical process seen as a continuity possible by the power of reproduction of the... |

| Some years ago I had the opportunity to study more extensively a very interesting group of grasses, belonging to what is now accepted as a distinct genus, the genus Digitaria, formerly belonging as a subgenus to the genus Panicum. As to living plants of this group I was familiar with two european species, also found in the Netherlands. They are treated in the Synopsis of Ascherson nd Gräbner and once more in the second edition of this work. Under Panicum they bear the names P. lineare KROCKER and P. sanguinale L. The first species belongs to HACKEL’S „Ternata”, the name is invalid on account of the Panicum lineare of LINNAEUS, a species described from India, we know that KROCKER’s plant does not occur in India and it is therefore necessary to look for the... |

| It has so often been emphasized that the flora of large tropical islands like New Guinea is still very imperfect, that the impression has been established that the data available should be in a state unapt to produce a conspectus or to procure valuable conclusions. Though it is certainly true that there are still immense plots of land entirely unknown from a botanical (or any other) point of view, and that we know but a part (but most probably more than one half) of the Papuan species of Pteridophytes and Spermatophytes, I am inclined to think that it is more than anything else the scattered nature of those data, that prevented us from realizing their intrinsic value. The time has come, I think, to pauze and to realize what has been done in the past years;... |

| Twenty-four years have elapsed since the Institution, then called „’s Rijks Herbarium”, started a series of papers entitled „Mededeelingen van ’s Rijks Herbarium, Leiden”. Exactly 70 numbers have been issued between 1910 and 1933 inclusive, most of them under the directorate of Dr J. W. C. GOETHART, to whom many thanks are due for his arduous work and his many cares in favour of these publications. After the undersigned, oil October 2nd, 1933, had taken over the directorate of the Rijksherbarium from the acting director, Dr W. A. GODDIJN, he could start realizing some projects which, in relation to his tropical experience, seemed more or less promising. First of all it was obvious that the Rijksherbarium should, to a greater degree than had been possible... |

| Vierentwintig jaren zijn verloopen sinds de instelling, die toen „’s Rijks Herbarium” heette, begon met de uitgave van een reeks publicaties onder den titel van „Mededeelingen van ’s Rijks Herbarium Leiden”. Juist 70 nummers zijn verschenen tusschen 1910 en 1933, met inbegrip van het laatstgenoemde jaar, de meeste daarvan onder het directoraat van Dr J. W. C. Goethart. Het is hier zeker de plaats Dr Goethart dank te brengen voor alles wat hij in die jaren voor deze uitgave van het Rijksherbarium heeft gedaan. Nadat ondergeteekende op 2 October 1933 het directoraat van het Rijksherbarium uit de handen van den waarnemenden directeur, Dr W. A. Goddijn, had overgenomen, kon een begin worden gemaakt met de uitvoering van enkele plannen, die in verband met zijn... |

| This paper deals with some specimens of Euphorbiaceae from various collectors. The plants have been collected in French and British Guiana. The specimens were sent to me for determination by the Kew Herbarium and the Herbarium of the New York Botanical Garden. Some of these specimens had to be considered as new species, others were new finds for British or French Guiana while the remainder of the list is added for sake of completeness. The author wishes to express his thanks to the directors of the Kew Herbarium and the Herbarium of the New York Botanical Garden for their assistance with the material. The arrangement of the genera is that of Pax in Engler, u. Prantl, Natürl. Pflanzenfam. sec. edition Vol. 19c (1931). |

| In the teaching of oceanography, the Gulf Stream theory is a dogma. Our children grow up with the history of this famous current; their eyes are obsessed by some beautiful coloured maps on which dark blue lines show, without any doubt, the itinerary of this marine river. Any traveller, captain, fisherman, passenger has seen the Gulf Stream with his own eyes. The entire western European coast owes its mild temperature to the warm waters sent by the Gulf of Mexico. I felt regretful the day I started doubting the existence, in the eastern Atlantic Ocean, of the branches of this beneficial current. Five years at the Roscoff Laboratory, an area especially privileged, had sparked my scepticism. Two polar cruises with Captain Charcot to the Jan Mayen Land,... |
