| In one of his papers on Malaysian Orchids R. Schleehter (1911) expresses his surprise that the flora of Celebes, though promising so much from a phytogeographical point of view, is very little known in comparison with that of the Philippines and Java and even with that of Borneo. In 1926 E. D. Merrill repeated this assumption with little less emphasis, and it is, indeed, still holding good even nowadays. I am not able to tell the reason why Celebes has been so much neglected in this respect, though it has been given ample attention by zoogeographers. Yet, botanical exploration has been carried out ever since the French scientific world cruises of the “Astrolabe” (1828) and the “Astrolabe” and the “Zelee” (1839). The more important collections have been... |

| 1 - Análise do Brix Em três das variedades analisadas - F 29-7, Co. 285 e Tuc. 519, - a diferença entre o Brix do caldo das canas florescidas e das canas não florescidas foi estatisticamente insignificante. Apenas em uma variedade - Co. 312 - tivemos um resultado duvidoso. Em F 29-7 nota-se que o erro nas' canas florescidas é maior que nas não florescidas, o que parece indicar uma tendência a maior instabilidade do Brix com o florescimento. A diferença entre os dois erros é, poréxn, de significação duvidosa, embora o valor de P exceda bastante o limite de 5% de probabilidade, sem atingir o de 1%. 2 - Análise dos redutores Houve uma diferença sem significação em F 29-7 e Co. 285. Em Co. 312, porém, o resultado foi duvidoso e em Tuc. 519 foi significante, e... |

| This paper reports a preliminary study of four sweet potato varieties, Russia, Napoleão, Roxa and Viçosa, carried cut in 1939-40 at the Central Experiment Station, Instituto Agronomico. Comparative plots of each variety were harvested after 3, 4, 5, 6, 7, 8 and 9 months of vegetation, the product being then examined for the following characters : a) Total yield b) Number of roots c) Average weight of the potates d) Production of different grades e) Qualities of the fresh roots f) Culinary value of the sweets potatoes The yield after three months of vegetation was very small for the four varieties, but increased considerably in the later harvests. The variety Napoleão attained its highest yield after six months, being early; Roxa yielded most after seven... |

| In the collection of the Leiden Museum there is preserved the holotype of Scotomedes ater Stål. I was much surprised to discover that Velocipeda biguttula Reut. is a synonym of it. Distant described another Scotomedes-species in his "Fauna of British India" under the name: Godefridus alienus, bringing it to the Reduviidae, subfam. Apiomerinae. This was a reason for derision by Reuter, who cited it as an instance of Distant's less trustworthy scientific performances (Reuter, 1905). However, though it seems to have been "bon ton" to ridiculize Distant's views, we are not accustomed to neglect Stål's, and I was much interested to know why Stål had placed Scotomedes without hesitation into the Nabidae, as other authors have been of a so much different opinion.... |

| In Januari 1944 was ik in de gelegenheid om het Orthopteramateriaal, aanwezig in het Laboratorium voor Entomologie te Wageningen, te bestudeeren. Aan Prof. Dr. W. Roepke, directeur van genoemd Laboratorium, wil ik hier mijn dank brengen voor zijn medewerking en voor de in zijn laboratorium genoten gastvrijheid. Behalve het materiaal in de studiecollecties voor de toegepaste entomologie is thans ook tijdelijk de particuliere verzameling van Ir. P. A. Blijdorp in dit laboratorium ondergebracht. Vooral deze laatstgenoemde verzameling bevat mooi materiaal. Het is betrekkelijk nog pas kort geleden verzameld, voor het meerendeel door Mevr. M. E. Walsh, in W.-Java en Z.-Sumatra. Hoewel misschien de meeste soorten niet tot de groote zeldzaamheden behooren, is het... |

| I. INLEIDING Ten behoeve van de N.V. Stoomschelpenzuiger- en schelpkalkbranderij te Brielle werd gedurende vele jaren schelpenmateriaal opgezogen in de Westerschelde ter hoogte van Ellewoudsdijk door den schelpenzuiger ,,Marie", eigendom van genoemde maatschappij. Dit materiaal, hetwelk naast Mollusca ook resten van Bryozoa, Foraminifera, Selachii en Brachiopoda bevatte, werd in afwachting van de verwerking in de kalkbranderij opgeslagen op het terrein bij de kalkfabriek. Nadere bijzonderheden over het bedrijf zijn reeds gepubliceerd door Dr. C. O. van Regteren Altena (1938). Dank zij de welwillende medewerking van den Directeur, Ir. P. van der Wallen, zijn vele malacologen in de gelegenheid gesteld schelpenmateriaal te verzamelen op het terrein der... |

| Professor I. Q. van Regteren Altena was zoo vriendelijk mij een aantal teekeningen ter beschikking te stellen, die eens aan het huis Plantijn moeten toebehoord hebben. Immers, sommige daarvan hebben gediend als voorbeeld voor houtsneden in den Herbarius von Dodonaeus van 1618, gedrukt „t'Antwerpen in de Plantynsche Druckerye van Balthasar Moretus" (zie Engel, in: Ned. Kruidk. Arch. 53, 1943, p. 46-55). Wanneer men de fraaie teekeningen vergelijkt met de reproducties in het Cruydtboeck, is het opvallend, dat de teekeningen losser, zwieriger en natuurlijker zijn, terwijl de houtsneden allerlei wijzigingen vertoonen, die klaarblijkelijk aangebracht werden ten einde de figuur in het formaat van het houtblok te doen passen. Toch komen beide tot in finesses... |

| In 1935 R. Zariquiey Cenarro published a paper in the Spanish language, in which he separated the specimens of Nephrops norvegicus occurring in the Mediterranean and the southern Atlantic Ocean as a separate variety meridionalis from the typical form of the northern Atlantic. In this paper he remarks that Boas as well as Bouvier stated that the second maxillipede of Nephrops norvegicus does not bear a podobranch. When Zariquiey, however, examined material from the Catalonian coast he found that in all his specimens a podobranch was present. For comparison with the northern forms he obtained an adult male and ovigerous female from Danish waters. In these specimens indeed the podobranch was absent, the maxillipede bearing only a rounded tubercle provided... |

| I. Introduction. In the Geological Institution of the University of Amsterdam there is a collection of recent shells as material for comparison with fossil Mollusca. From this collection the writer identified a lot of shells collected by Professor Dr. H. Gerth during his stay in Java from 1928 to 1929. These materials will be discussed here. The writer is indebted to Prof. Dr. H. A. Brouwer (Amsterdam) for his permission to publish the results of these investigations on materials belonging to the Geological Institution, to Prof. Dr. H. Gerth for placing at his disposal the present collection and his field notes, and further to Dr. Ch. Bayer (Leiden), Mrs. W. S. S. van der Feen-van Benthem Jutting (Amsterdam), Mr. L. de Priester (Apeldoorn), Dr. F. A.... |
