| In het Onderbos ten Westen van Apeldoorn, dat thans door de gemeente Apeldoorn omgezet wordt in een sportpark, en dat tot dusver over het algemeen uit een arm Querceto-Betuleturn bestond, bevinden zich belangrijke overblijfselen van de middeleeuwse ijzerindustrie, die op de Veluwe gebloeid heeft van de 8ste tot . de 12de eeuw. Hiertoe behoren de twee grootste ijzerslakkenhopen van Europa, voorzover bekend, Haar aanleiding van een bericht, dat ook deze zouden verdwijnen, heeft de heer S. van der Werf, verbonden aan het Laboratorium voor Plantensystematiek en -geografie der Landbouwhogeschool, in de zomer van 1956 deze slakkenhopen botanisch onderzocht. Zij bleken een rijke en interessante flora en vegetatie te bezitten, groeiende op een in de loop van de... |

| Utricularia is represented in Malaysia by two main kinds of plant, i.e., aquatic and terrestrial. The aquatic species can again be divided into two main groups, those which float freely in still water and those which are more or less anchored in and beneath shallow water. All of the aquatic species consist of long branching stolons bearing leaves which are divided into capillary segments and traps. The racemes of small yellow, violet, or purple flowers arise from the stolons and project a few inches above the surface of the water. The terrestrial species (including a few which are epiphytic) consist of slender rhizoids bearing linear, spathulate or peltate leaves and traps. These grow on or just below the surface of damp soil and are usually very... |

| In 1953, Mr. E. C. Stol, naturalist at Leiden, kindly placed at my disposal a small collection of Surinam freshwater aquarium fishes. A second collection, consisting of freshwater and marine specimens from Surinam, mainly collected by Dr. D. C. Geijskes and Mr. H. W. Lijding (Fishery Department), was received during 1954. As the two collections proved to contain several interesting specimens belonging to species not yet reported from Surinam, the following enumeration is given. To the measurements of specimens with damaged caudal fins the mark is added. Dasyatis guttata (Bl.; Schn.) 1 ex., near lightship Surinam River, 5-8 miles E., 12 January 1954, H. W. Lijding, 412 mm, ♂. Further data: length of disc (to anus) 97 mm; length of tail (from anus) 315 mm;... |

| In Juni, Juli en September 1955 werden aan de oever van het gedeelte van de Maas, dat door het Juliana-kanaal is afgesneden, resp. door een I.V.O.N.-excursie, de excursie van de Commissie voor het Floristisch Onderzoek uit de K.N.B.V. en ondergetekenden een opvallend groot aantal adventieven verzameld, waarvan een 10-tal nog niet eerder in Nederland was aangetroffen. Door de zeer lage waterstand hadden deze adventieven zich volop kunnen ontwikkelen op plaatsen, waar door het graven van grint vele kuilen waren ontstaan en op de zand- en rolsteenstrandjes aan de luwe zijde van de bochten van de rivier. De zaden en vruchten zijn wel zeker door de Maas aangevoerd van hogerop in het stroomgebied gelegen fabrieken en losplaatsen; de wolfabrieken aan de Vesdre... |

| In the collection of the Haifa Sea Fisheries Research Station, among material trawled in Mersin Bay, S. E. Turkey, two Brachyuran crabs were found which prove to be of great interest. One, Actaea rufopunctata (H. Milne Edwards), has a rather wide distribution in both the Atlantic and the Indo-West Pacific regions, but only very few records from the Mediterranean are known as yet. The other, Ixa monodi, a species of IndoWest Pacific origin, is new to science, while the genus to which it belongs is now reported for the first time from the Mediterranean. Actaea rufopunctata rufopunctata (H. Milne Edwards, 1834) (pl. IV fig. 1) An ovigerous female (cb. 20 mm) 1) was trawled in Mersin Bay in August 1954. The specimen fully agrees with the published accounts of... |

| The islands of Aruba, Bonaire and Curaçao form part of a row of small islands off the north coast of Venezuela. Aruba lies 27 km north of the peninsula of Paraguaná and 76 km west of Curaçao; it is separated from the former by a stretch of sea with a maximum depth of 180 m, and from the latter by a channel 1,300 m deep. Bonaire lies 40 km east of Curaçao and 87 km from the South American continent; it is separated from the former by a stretch of sea with a maximum depth of 1,500 m, and from the latter by a stretch of sea with a maximum depth of 1,700 m. Curaçao lies 64 km from the peninsula of Paraguaná and is separated from it by a stretch of sea with a maximum depth of 1,400 m. |

| On the basis of the morphology and stratigraphic positions, the bauxite deposits in Suriname and Demerara (British Guiana) were divided into four main groups, namely: 1. Plateau type bauxite, 2. High-level type bauxite, 3. Medium-level type bauxite, 4. Low-level type bauxite. The age of these deposits is as follows: Plateau type bauxite .................................... Pre-Tertiary Low-level type bauxite ................................ Middle- to Lower-Tertiary High-level and Medium-level type bauxite .... Pleistocene These three main periods of bauxitization have led to the formation of fossil bauxite. After these main periods the bauxitization process, however, has not come to a standstill. It continues even at the present time, although less... |

| Orchis simia Lamk. Bij het doorzien van het onderwijs-herbarium van de R.M. Landbouwschool te Dordrecht werd door mij het enige uit Nederland bekende exemplaar van deze soort teruggevonden. Dit exemplaar was indertijd afgebeeld in de Flora Batava, doch in tegenstelling met de meeste daar afgebeelde planten, niet aanwezig in de collecties van het Rijksherbarium of de K.N.B.V. Hoe de plant in Dordrecht is terechtgekomen, is onbekend. Zij werd verzameld in de duinen bij ’s-Gravenhage door R.H. Haverman op 28 Mei 1905 en werd onlangs door de heer J. Guittart, leraar aan genoemde school, aan het Rijksherbarium geschonken, -v.O. Een merkwaardige van Carex brizoides L.

| Anticipating a revision of the genera and subgenera of the tribe Anthophorini, a number of south-east Asiatic species previously included in Anthophora Latreille, are transferred by the author to Amegilla Friese. The types were studied of Anthophora villosula F. Smith, and of 19 valid and 3 invalid species of Amegilla (i.e., of all species discussed, except that of himalajensis Radoszkowski), and a key to their identification is included. The following new species are described: A. proboscidea, ♀ (Simalur I.), sumatrana, ♂♀ (Sumatra), pagdeni, ♂ ♀ (Malaya), and leptocoma, ♂ ♀ (Siam & Malaya). Re-descriptions of both sexes and figures are given of A. insularis (F. Smith), himalajensis (Radoszkowski), florea (F. Smith), and urens (Cockerell). Apart from... |

| During the zoological exploration of Netherlands New Guinea sponsored by the Rijksmuseum van Natuurlijke Historie, Leiden, in 1954-1955, four specimens of Clausiliidae were found. There are no previous records of the occurrence of Clausiliidae in New Guinea; the most eastern locality in the Indo-Australian region from which this family of snails was known is the island of Halmahera, in the Moluccas (Loosjes, 1953, p. 209). Paraphaedusa minahassae (P. & F. Sarasin, 1899) Sarasin, 1899, p. 218, pl. 26 figs. 267-268. Ehrmann in Zilch, 1949, p. 77, pl. 4 fig. 10. Loosjes, 1953. P. 137, fig. 38. The specimens show the characters as they are typical of the species, but the aperture of some of the shells is somewhat narrower than usual, and the right upper... |

| Bryophyta. The new collections built up during the last years under the supervision of Prof. R. van der Wijk, Groningen, have now all been arranged and provisionally been identified by him and his collaborator Mr Margadant. Revisional work has started. Pteridophyta. A most important collaboration, anticipated for years, is that of doctors Holttum, Kew, and Alston, London, who have now definitely agreed in compiling the series II of the Flora Malesiana containing the account of the Pteridophyta. Dr Alston spent a year (Oct. 1955-Oct. 1954) in Indonesia on the invitation of the Indonesian Government. Dr Holttum has finished his large work on the ferns of Malaya; he is now finishing off an account of the bamboos of Malaya and will then set definitely to the... |

| Op 3 Sept. jl. overleed te Deventer Dr. H.R. Hoogenraad, oud-leraar aan de Rijkskweekschool voor Onderwijzers aldaar. Zijn herbarium werd door Mevr. M.M. Doornink-Hoogenraad te Zutphen aan het Rijksherbarium geschonken. Het bevat naast buitenlands materiaal (uit W. Europa) ook een groot aantal Nederlandse planten, o.a. exemplaren van Thesium pyrenaicum Pourr., afkomstig van de enige, thans verdwenen, vindplaats bij Gorssel. De heer N.P.W. Balke te Rotterdam schonk zijn collectie Nederlandse planten aan het Rijksherbarium. De collectie is vooral van belang door het groot aantal adventievens dat zij bevat. |

| The genus Stenandriopsis was created by S. Moore in Journ. of Bot. 44: 153. 1906 for a plant collected first by Vaughan Thompson and afterwards by Baron in an unspecified part of Madagascar. As the plate by which the description is accompanied depicts the specimen collected by Baron (n. 6708), the latter is to be regarded as the type. Stenandriopsis was referred by its author to the Justicieae, but this tribe is apparently accepted by him in the delimitation it received in BENTHAM and HOOKER’s “Genera Plantarum”, and as it is in this sense a most heterogeneous mixture, this does not greatly enlighten us. Of more importance is that Moore compares it with Crossandra Salisb. and Stenandrium Nees, i.e. with genera belonging to my subfamily Acanthoideae and... |

| Akademi Biologi, Bogor. The Indonesian Government is anxious to develop training in biology; the failure of the University of Bandung Faculty to achieve this (due to shortage in staff personnel) has necessitated making temporary use of the personnel of the Kebun Raya Indonesia towards this goal. With freedom of choice and with an extra-allowance, a number of staff members of K.R.I, has agreed to give each a few lectures at the Akademi Biologi, Bogor. The course is intended to last 3 years, when a degree can be obtained which is in standing assumed to be slightly under a bachelor’s degree. Personnel thus raised will be partly required for the Gardens, partly for teaching purposes in secondary schools; each year a few excellent students will be selected to... |

| Explanation of the geological map (Northwestern part) of the province of La Coruña, Galicia, N.W. Spain Main rock groups We distinguish five main groups of rocks which probably differ in age. Whether this age difference applies only to the time of their intrusion or metamorphism or also to their sedimentary origin remains obscure. These five groups are from top to bottom in the time scale: — (1) Younger rocks, mostly not tectonized, post tectonic. To this group belong: (a) a red sandstone patch west of Malpica on the coast, unconformable on the underlying schists, age unknown; (b) the Traba granite pluton and some other plutonic rocks south of it; (c) rhyolitic or syenitic dykes south of the Traba granite; (d) a swarm of WNW striking basic dykes, mostly... |
