| 1. For the first time, <i>Crepidula fornicata</i> was observed in Belgium on 28-9-1911; in 1959, it became an oyster pest. 2. It was first introduced into Belgium with seed oysters from Great Britain. Later on, with seed oysters from the Netherlands. 3. Probably, the geographical spreading is caused by the adult animals attached to oysters. Larval propagation is responsible for local extension. 4. In the sluice-dock at Ostend, larvae occur from the middle of May till the end of November; they swim freely for a period of about 12 days. The first massive emission of larvae is observed during May and June, a second one in September. 5. The larvae settle preferentially at a depth of 65 cm. 6. Maximum settling takes place in May. It then decreases... |

| Balan Menon, P.K.: Taxonomic value of wood anatomy seen through Malayan woods. The Malayan Forester 24 (1961) 290- 301. Mr Menon, who is a wood technologist at the Forest Research Institute, Kepong, Malaya, presented this paper at the Hawaii Congress. In it, he gives a series of classifications of Malayan woods on the basis of anatomical features which can be seen by a hand-lens, he distinguishes 18 classes, notably woods with: ring-porous structure, exclusively solitary pores, multiple vessel-perforation, vestured (vessel) pits, scalariform intervessel pits, ripple marks, broad rays, uniseriate rays, septate fibres, distinctly bordered fibre pits, tanniferous tribes, latex tribes, horizontal canals, vertical canals, included phloem, mucilage or oil cells,... |

| Nature Conservation in western Malaysia, 1961. Edited by J. wyatt-Smith & P.R. Wycherley. An issue to mark the occasion of the 21st anniversary of the founding of the Malayan Nature Society 1940-1961. viii + 258 pp., 44 plates, maps. There is all reason to congratulate the Malayan Nature Society with her coming of age. On account of this fact, she presented herself to the world with a book that we are exceedingly glad to review here. It consists of an introduction by Mr E.J.H. Corner, F.R.S., and 46 chapters which cover surprisingly many aspects of Nature Conservation and Environment, National Parks, and Wilf Life, these being three sections of the four into which the book has been subdivided; the fourth is General. The book has been copiously... |

| Com o presente trabalho procurou-se estudar a relação entre a água do solo e a tensão com que ela é retida nos principais tipos de solos do Estado de São Paulo, tais como: terra-roxa-legítima (de mata e intensamente cultivada), massapê, arenito Bauru e arenito Botucatu, subdivididos em 5 camadas de 0-15, 15-30, 30-45, 45-70 e 70-100 centímetros de profundidade. Amostras de solo foram saturados e submetidas à seguinte série de tensões: 0,1, 1, 3, 8, 15 e 20 atmosferas, sendo opresentadas os curvas características de umidade dos solos estudados, para essas tensões de umidade que estão compreendidas entre o ponto próximo de saturação e o limite inferior da faixa de disponibilidade de água para as plantas. Essas curvas mostram que, nos solos estudados, é... |

| This publication represents a continuation of a previous article on the Caribbean Vertiginidae (this series, Vol. X, 1960, No. 41), and it will follow the same arrangement as the former. This will not only add to the uniformity of the series, it will, furthermore, make it simpler to compile individual faunal lists from any locality situated within the region treated here. Yet another continuation will follow this article, in which some smaller families with their representatives in the Caribbean region will be listed. The photographs (Plates X E and XI I excepted) were again taken by Dr. P. WAGENAAR HUMMELINCK, with the technical assistance of Mr. H. VAN KOOTEN, at the Zoological Laboratory of the State University, Utrecht. |

| Catapodium marinum (L.) Hubbard has its northern limit on the continent in the Netherlands. Up to now it was known here from 4 localities only. In 1960 the author discovered two new and very rich localities on the isle of Walcheren between Domburg and Westkapelle. It is supposed that the plants have reached one of these localities as a result of the inundation after the great flood of 1953, and the other with rubble from Westkapelle, which village was destroyed during World War II, and inundated afterwards. |

| The mediterranean-atlantic species Catapodium marinum (L.) Hubbard reaches its northern limit on the continent in the Netherlands. Up to 1959 only 2 localities on the Dutch coast were known. In 1961 the species was discovered in large quantities on the brackish estuary shore of the island of Goeree, by far the richest occurrence in the country. The habitat in the three Dutch localities is similar: low, sandy, dry, irregularly submersed dunes in the ecotone between xerosere and halosere, with fluctuating, but mostly low, salt content and rather high lime content; i.e. in the dry desalinated “Koelerion”-variant of the Saginetum maritimae. Scirpus planifolius Grimm, another ecotone species, is rather common in Britain, but much rarer on the continent,... |
