Notes on a collection of Crustacea Decapoda from the Great Bitter Lake, Egypt, with a list of the species of Decapoda known from the Suez Canal Naturalis
Holthuis, L.B..
Between August 18 and September 5, 1950, Dr. C. Beets, geologist Royal Dutch Shell Oil Company, explored the aquatic fauna and flora of the Great Bitter Lake. In the course of this exploration dredge hauls were made at 47 stations, distributed all over the lake. An account of this work and a description of the stations were given by Dr. Beets in a previous volume of the present journal (1953). The Decapod Crustacea collected by Dr. Beets belong to twelve species, three of which have not been reported from the Suez Canal before. Apart from these additions to our knowledge of the fauna of the Suez Canal, the present collection is of great interest because of the extensive data provided by Dr. Beets on the ecology of the localities from which the material...

Hispinae aus Indonesia Naturalis
Uhmann, Erich.
Die erste Dactylispa-Art, und überhaupt wohl die erste auf der Insel Bali gesammelte Hispina. Sie zeichnet sich aus durch die ganz dünnen, körperlangen Fühler (Abb. 1). Sie sind noch dünner als die von D. spinosa WEBER, vor allem sind sie zur Spitze nicht verdickt. Sie sind den Fühlern von D. vethi GEST. ähnlich, aber noch dünner. D. praegracilis gehört in den Vethi-Kreis (siehe meinen 135. Beitrag, Philippine J. Sci. 83, 1954, p. 3). Sie ist dort auf p. 28 neben D. sinuispina GRESSITT zu stellen. Gelbbraun, Halsschild mit zwei schwarzen Längsflecken, Decken schwarz mit Ausnahme des abgeflachten Seitenrandes und der dazugehörigen Dornen, am Hinterwinkel der Seitenrand mit seinen Dornen schwarz. — Stirn konvex, zwischen den Fühlern mit scharfem, dünnem...

Een adventiefterrein in Friesland Naturalis
Ploeg, D.T.E. van der.
Het aantal adventieven, dat wij tot nu toe in Friesland vonden, was zeer gering. Wel was ons bekend, dat in vroeger jaren op de terreinen van de Koopmans Meelfabrieken te Leeuwarden verscheidene (niet gepubliceerde) vondsten waren gedaan, maar het gelukte ons nooit daar enig spoor van terug te vinden. De direktie van de meelfabrieken was echter zo vriendelijk ons mee te delen, dat de graanverontreinigingen vervoerd werden naar het vuilverwerkingsterrein van de gemeente Leeuwarden, gelegen onder Wartena. In de nazomer van 1955 bezochten wij dit terrein voor het eerst en inderdaad bleken hier verscheidene adventieven voor te komen. Dat het terrein tot nog toe aan de aandacht van de floristen is ontsnapt, is ongetwijfeld te wijten aan de ligging. Men kan het...

The valid name of the Banteng: Bibos javanicus (d'Alton) Naturalis
Hooijer, D.A..
While studying the collection of recent oxen of the Museum my attention was drawn to the problem of the nomenclature of the Java banteng. I believe to have been able to clear up the confusion that still exists today, as will be set forth in the present note. The wild ox of Java, the banteng, is known variously as Bos sondaicus or Bos banteng, but neither of these is the earliest available valid name. The species should have been called: Bibos javanicus (d'Alton) B[os] Javanicus d'Alton, Skelete der Wiederkäuer, Bonn, 1823, p. (7), pl. VIII fig. c. The earliest reference to the banteng of Java I have been able to find is in Pennant (1800, p. 35): "Mr. Loten told me that wild oxen, of a reddish brown color, with vast horns, and of a great size, are found in...

A short survey of the American species of the genus Octohlepharum Naturalis
Florschütz, P.A..
During my studies of the Surinam specimens belonging to this genus my attention was drawn to the often wrong interpretation of several old species. To avoid future misidentifications it seems useful to give a short review of the American species that are known up till now. It is emphasized, however, that this paper does not have the pretension to be a monograph of the American species. For the greater part my study of the species was confined to the type material and the variability therefore is not known. However, this contribution may serve as a base for a future monograph of this interesting group. Attention is drawn to the fact that only older leaves of the plants should be studied, because the leaf apex of the younger leaves is in all species acute...

Notes on the Marantaceae of Suriname Naturalis
Jonker-Verhoff, A.M.E.; Jonker, F.P..
The list of Marantaceae published by PULLE (1906) comprises 20 species belonging to 6 genera, the largest genus being Calathea with 8 species. It was found, however, that one of the species does not belong to the family: investigation of the type of Calathea strobilifera (Miq.) Koern., viz. Kegel 1469 [GOET], showed that it pertains to Renealmia strobilifera Poepp. et Endl. (Zingiberaceae). The record of another species, Calathea allouia (Aubl.) Lindl. appeared to be based on a misidentification: the collection Focke 893 cited under this name by PULLE (1906) belongs to C. grandis O. G. Peters. Later on PULLE (1909) recorded the occurrence of one species more of this family in Suriname, viz. Myrosma polystachya Pulle, a new species. Since then no further...

Lichomolgus longicauda (Claus, 1860), Copepod parasite of Sepia, in the North Sea Naturalis
Stock, J.H..
Lichomolgus longicauda (CLAUS, 1860), is recorded from the gills of Sepia officinalis, captured on 5 different occasions in the North Sea and the Dutch Waddensea. This means a northward extension of the range of this species of more than 8 degrees of latitude. Figures of the parasite have been provided, and the literature bearing on the species has been reviewed.

Structural features round las Bordas, Valle de Aran, central Pyrenees Naturalis
Alphen, G.J. van.
On the suggestion of Prof. Dr L.U. de Sitter I undertook in the summer of 1955 the detailed mapping of some particular intricate folding combined with some intrusive rocks of different kinds in the vicinity of the village of Las Bordas in the Valle de Arán. A grant from the Molengraaff Fund gave me financial assistance, for which I want to express my grateful thanks.

Het I.V.O.N. – Werk Naturalis
Ooststroom, S.J. van.
Het Instituut voor het Vegetatie-onderzoek van Nederland (I.V.O.N.) werd opgericht in 1930 en is thans gevestigd in het Rijksherbarium, Nonnensteeg 1 , Leiden, Het stelt zich o.a. ten doel om door stelselmatige inventarisatie een overzicht te verkrijgen van de verspreiding der in Nederland voorkomende Pteridophyta en Spermatophyta. Reeds in 1902 werd door de heren Dr. J.W.C. Goethart en W. J. Jongmans, destijds resp. conservator en assistent aan het Rijksherbarium, een aanvang gemaakt motdit biogoo grafische onderzoek. In de jaren daarna werd het met medewerking van een aantal Nederlandse floristen voortgezet, waarna men wegens de toenemende betekenis van het werk en met medewerking van de heren Goethart en Jongmans in 1930 kwam tot de oprichting van het...

Parnassiana nova : VIII. Kritische Revision der Gattung Parnassius (Fortsetzung 5) Naturalis
Eisner, C..
In dieser Fortsetzung werden die weiteren französischen und die spanischen Subspecies von Parnassius apollo L. behandelt. Bryk zieht im Tierreich bei seiner Einteilung in Rassenkreise zum Jurassischen Kreis auch die subspecies leovigildus Fruhst. und venaissnus Fruhst., die ich indessen als zu dem französischen Alpenkreis zugehörig ansehe, dem ich mich im folgenden zuwende. Bevor ich das indessen tue, will ich noch die Beschreibung einiger französischer Rassen erwähnen, die ich vom Augenschein nicht kenne; ich muss mich darauf beschränken, ohne beurteilen zu können, ob es sich um bonae subspecies handelt. subsp. anneciensis Testout (Bull. Soc. Linn. Lyon XVI, p. 64, 1947, Typus Thônes, Hte-Savoie). subsp. vercorcius Testout (Bull. Soc. Linn. Lyon v. 11 und...

La géologie des environs d’Estours Naturalis
Wissink, A.J..
Pendant les étés de 1953, 1954 et 1955, j’ai eu l’occasion d’étudier une partie des Pyrénées centrales, qui se trouve au sud de St. Girons sur le bord de la zone axiale. Le terrein étudié, mesurant à peu près 140 km2, comprend partiellement les vallées de Bethmale, du Salat et de l’Alet et entièrement les vallées d’Estours et d’Esbints. Je tiens à exprimer ma reconnaissance à la „Stichting Molengraaff” de m’avoir donné une subvention qui m’a permis d’effectuer mon deuxième stage sur la terrain.

Parnassiana nova : IX. Kritische Revision der Gattung Parnassius (Fortsetzung 6) Naturalis
Eisner, C..
In dieser Fortsetzung werden die schweizer und italienischen subspecies von Parnassius apollo L. behandelt. Bevor ich mich der Behandlung des schweizer Rassenkreises im einzelnen zuwende, möchte ich etwas tiefer auf ein Problem eingehen, das ich schon kurz gestreift habe, und das auch andere Parnassiologen/Entomologen wiederholt beschäftigt hat. Was ist die Ursache der überaus grossen Variabilität der Parnassier und welche Einflüsse bestimmen das Aussehen der einzelnen Individuen und der Unterarten? Es gibt zweifellos in ihrer Erscheinungsform gefestigte Rassen, die bei aller individuellen Variabilitätsbreite im Rahmen der betreffenden species eine sichere Bestimmung der einzelnen Individuen hinsichtlich ihrer Rassenzugehörigkeit auch ohne Fundortsangabe...

Geology of the eastern zone of the Sierra del Brezo (Palencia-Spain) Naturalis
Kanis, J..
In het noordwestelijk deel van de provincie Palencia vormt de Sierra del Brezo een onderdeel van de Cordillera Cantábrica. Het resultaat van een geologische kaartering van het oostelijk gedeelte der Sierra del Brezo met zijn aangrenzend gebied is weergegeven in de hier bijgevoegde geologische kaart (schaal 1:25.000). Zowel een onderzoek der stratigrafie, als van de tektoniek leidde tot nieuwe gezichtspunten omtrent dit Palaeozoïsch gebied. Verder wordt in dit werk de petrografie van tien waargenomen gangen besproken en werd aandacht besteed aan het voorkomen van ertsen, t. w. ijzer en koper, en van steenkolen. Dit gebied, dat bijna geheel uit Devonische en Carbonische afzettingen bestaat, is zeer rijk aan fossielen. Vooral het Devoon tussen Ventanilla en...

Parnassiana nova : X. Zwei neue nordamerikanische Parnassius Subspecies Naturalis
Eisner, C..
Parnassius clodius hel subsp. nova Schon die erste Sendung einer grösseren Anzahl von P. clodius Ménétr., die ich von D. Frechin empfing, enthielt Exemplare, die in den Mts. Cascade, Washington, gefangen waren und ein von dem übrigen clodius-Material, das vom Gorst Creek, Bremerton, Bear Creek, Tahuyah Creek, Mission Creek, alle Washington-State, stammte, verschiedenes Aussehen zeigte. Eine zweite grössere Ausbeute aus den Mts. Cascade bestätigte meine Vermutung, dass es sich bei den Tieren vom Stevens Pass 4500' und Berne 3500' um eine distincte Höhenrasse handelt, die sich zu subsp. claudianus Stich. wie subsp. baldur W. H. Edw. zu der Stammform verhält. Allerdings zeigt die neue Unterart eine subsp. baldur W. H. Edw. entgegengesetzte...

Quelques noddees sur l’ecologie de la vedetation des dunes et sur la fonction de l’enraciment dans l’edification de dunes a la Cote Mediterraneenne de la France. II Naturalis
Boterenbrood, A.J.; Donsellaar-Ten Bokkel Huinink, W.A.E. van; Donselaar, J. van.
Une évaluation des plantes d’après leur pouvoir édificateur de dunes doit être précédée d’une description de leur structure a côté de l’étendue et de la densité des organes aériens il faut considérer d’importance capitale et décisive la structure des organes souterrains, tel que KÜHNHOLTZLORDAT (1923) et VAN DIEREN (1934) l’ont suggeré. Les organes souterrains peuvent être: des rhizomes, des racines, ou des tiges ensevelies par le sable meuble. Une comparaison des différentes qualités mène à la distinction de groupements et à la création d’un système.

Revision of Greenidae and related genera (Homoptera, Aphididae) Naturalis
Ray Chaudhuri, D.N..
The present paper contains the results of studies on the tribe Greenideini of the subfamily Greenideinae Takahashi, 1931, a primitive group of Aphididae mainly restricted to East Asia. Material could be studied of twentyseven species described by previous authors, while seven species had to be described as new. Some changes had to be effected in the systematic arrangement, so that at present six genera (old and new) are recognised in the group, together including five subgenera. In spite of repeated attempts not all the species so far described could be examined, accordingly in a final chapter notes are added on the species that were not available. The project for carrying out research work on Aphididae could be realised through the kind help of Mr. D....

The vegetation of the Netherlands Antilles Naturalis
Stoffers, A.L..
This vegetation survey is the outcome of an investigation of the islands of the Netherlands Antilles carried out under the auspices of the Foundation for Scientific Research in Surinam and the Netherlands Antilles. The data on which the present study is based were obtained during a trip which lasted from September 1952 until October 1953. During this trip the following islands were visited: Curaςao, Bonaire, Aruba, St. Martin, Saba, and St. Eustatius. A short visit was also paid to the island of St. Kitts (B.W.I.). The present work gives an account of the actual vegetation of the Netherlands Antilles. Other studies, comprising the systematic results and conclusions of the survey, are being prepared, and will possibly be published in 1958.
