| In 1929 werd in het kader van het Zuiderzee-onderzoek door Mevr. D.Koopmans-Forstmann en A.N. Koopmans een onderzoek ingesteld naar het voorkomen van Caltha palustris L. in Friesland (Mededeling no. 9 van de Zuiderzee-commissie; N.K.A. 1930). Uit dat onderzoek bleek dat Caltha in de Westelijke helft van Friesland nagenoeg geheel ontbrak. De grenslijn bleek van Leeuwarden naar Sneek de grens tussen klei en veen te volgen. Uit het noordwestelijke kleigebied werd geen enkel bericht van hot voorkomen van Caltha ontvangen. In het kleigebied ten Zuiden van Sneek (het merengebied) werden enkele voorposten ontdekt n.l. Gaastmeer, Oudega (W.) on verder enkele plaatsen in de omgeving van Woudsend, De vindplaats, die het dichtst de Zuiderzee naderde, was een weiland... |

| Wasps of the genus Gasteruption are predator-inquilines of bees nesting in cavities in wood, stems, galls, and vertical soil surfaces. During studies of hymenopterans associated with reed galls caused by flies of the genus Lipara we recorded three species. We provide the evidence that a rare European species Gasteruption phragmiticola is a specialized predator-inquiline of an equally rare wetland bee Hylaeus pectoralis. Gasteruption nigrescens is a predator-inquiline of bees of the family Megachilidae, using the common bee Hoplitis leucomelana as the main host. Gasteruption assectator is a less specialized predatorinquiline of multiple groups of bees. The first two species, G. phragmiticola and G. nigrescens, are usually present at well-preserved reed... |

| La forme est le phénomène de la vie le plus important. Aussi on pourrait croire que toute étude biologique devait commencer par la forme. En effet aucune fonction n’est imaginable indépendante de la forme, tandis qu’on peut étudier la forme indépendemment de la fonction, par exemple à des objets morts. Cependant depuis Sachs le botaniste moderne est tellement possédé par les conceptions matérialistes et mécaniques, qu’il veut aussi expliquer causalement les formes organiques en oubliant que, même si toutes les formes sont matérielles, cela ne veut pas nécessairement dire que les lois physiques et chimiques qui dominent la matière sont capables d’expliquer la forme, c.à.d. l’organisation des êtres vivants. A l’aide de briques on peut bâtir des bâtiments les... |

| In the spring of 1980, from the end of March till in July, I visited the eastern part of the Spanish province of Oviedo and the adjacent part of the province of Leon. The main subject of investigation during this period was the species Rana temporaria (Veenstra 1981). I tried to find out where this species could be found and while doing so I determined the occurrence of more species of amphibians. Totally twelve species of amphibians could be observed. Characteristics of their reproduction sites are listed and worked out below. |

| Leucojum aestivum L. In het verspreidingskaartje van het genus Leucojum (Gorteria 2, no. 12, p. 152) is het areaal van L. aestivum gearceerd aangegeven. Niet gearceerd zijn de Balearen en Sardinië, waar L. aestivum L. var. pulchellum (Salisb.) Fiori voorkomt. Deze gebieden zijn binnen het areaal van het genus Leucojum wit gelaten, omdat niet met zekerheid kon worden vastgesteld, dat L. pulchellum Salisb. inderdaad moet worden beschouwd als een variëteit van L. aestivum. Mocht dit zo zijn, dan heeft het gearceerde deel van het verspreidingskaartje betrekking op L. aestivum L. var. aestivum. |

| Some time ago our Museum received a very young specimen (in liquor) of Orthragoriscus-spec.? This acquisition to the series of O.-specimens in the Leyden Museum gives me an opportunity to publish the observations I made in comparing this young animal with the other specimens in our collection. The drawing (3 X natural size), joined to this publication, is made under my direction by Mr. Raar and is a most exact one. |

| The reduction of Nelsonia campestris R.Br. to N. canescens (Lam.) Sprengl. was not justified; N. campestris is a species confined to Australia or, perhaps, to Australia and New Guinea; arguments are adduced against Bentham’s view that N. campestris would be a common tropical weed. Thunbergia arnhemica F. v. Müll. was erroneously sunk in Th. fragrans Roxb.; the latter is confined to India and Ceylon and Th. arnhemica to Australia. Ruellia acaulis R.Br., R. australis Cav., R. pumilio R.Br. and R. spiciflora F. v. Müll. ex Bth. are transferred to a new genus Brunoniella, which is confined to Australia. |

| Mr J.A.R. Anderson of Kuching, Sarawak, has been awarded the degree of Ph.D. by the University of Edinburgh, in absentia, on July 6, 1961. The title of his thesis is: The ecology and forest types of the peat swamp forests of Sarawak and Brunei in relation to their silviculture. It is a privilege to insert a summary of it in this Bulletin under VII. For a reference to a preliminary paper, see Bibliography. Mr I.H. Burkill was congratulated on attaining his 90th birthday, May 18, 1960, and, as we learnt from Dr. Holtturn, he in the meantime celebrated his 91th in excellent health. In honour of his birthday the Gardens’ Bulletin, Singapore, vol. 17, part 3, was dedicated to him and filled with some special articles by Dr. H. Santapau, Mr C.X. Furtado, and... |

| His Excellency, the present Governor General of Dutch India J. W. van Lansberge, Bart. L. L. D. by repeatedly authorizing exploring expeditions into different parts of the Indian Archipelago has given a glorious example how to promote a science which he cultivates himself most ardently. Mr. J. E. Teysmann honorary Inspector of the cultures at Buitenzorg in the isle of Java, put at the head of the expedition, was accompanied by a certain number of hunters for the purpose of collecting and preparing zoological objects. During a visit in the district of Macassar in the southern part of Celebes, the party met with the undiscribed species of heron, the epithet of which will serve to remember the name of one of the few high functionaries, who appreciate the... |

| Dr J. J. Smith is best known by his studies about Orchidaceae. But since 1904 he published regularly in collaboration with Dr J. C. Costerus in the ”Annales du Jardin Botanique de Buitenzorg“, the results of their researches in teratology of tropical plants. Some years ago, Dr J. J. Smith was so kind to ask me if I would like to continue their studies in tropical teratology; I accepted this invitation. Although botanists appreciate this part of the botanical science in more than one way, and although even the opinion about the definition of a monstrosity differs, it must be stated that what has been done by Costerus and Smith in this field of the botanical science, deserves our high appreciation as they have described and pictured for the first time a... |

| Sarawak — The Sarawak Biodiversity Centre (SBC) Ordinance, 1997 and the Sarawak Biodiversity (Access, Collection and Research) Regulations, 1998, are two laws that have been enacted by the State to achieve the twin aims of protecting Sarawak’s biodiversity and recognising its importance. Under the Regulations, anyone who wants to access, collect, do research on or use the biological resources of the State is required to apply to the Sarawak Biodiversity Centre Council for a permit. Penalties for accessing, collecting, or doing research on the biological resources of the State without a permit are a fine of up to RM 20,000 and/or a jail sentence of up to three years. The Permit system is to ensure the proper regulation of access to and utilisation of the... |
