| For the first time a systematic study of the types and authentic specimens of agarics and boletes preserved in the Persoon Herbarium has been carried out. Some aspects of the possibilities of type analysis with regard to specimens over 130 year old are discussed. 137 species were analyzed. The following new combinations are proposed: Mycena amygdalina (Pers.) Sing., Psilocybe angulata (Batsch ex Pers.) Sing., Inocybe argillacea (Pers. ex Pers.) Sing., Lepiota aspera var. acutesquamosa (Weinm.) Sing., Pseudoclitocybe bacillaris (Pers.) Sing., Acurtis chalybeus (Pers. ex Fr.) Sing., Hemimycena cucullata (Pers. ex Fr.) Sing., Tubaria dispersa (Pers.) Sing., Omphalia grossula (Pers.) Sing., Campanella merulina (Pers.) Sing., Mycena phyllogena (Pers.) Sing.,... |

| One of the pioneers of nematology was the Dutch zoologist Dr. J. G. DE MAN (1850—1930). His contribution to this science consisted of 44 papers (VAN BENTHEM JUTTING, 1951), which were largely taxonomic and faunistic in character. The total number of new nematode genera described by him is 50, of new species 229. Apart from the publication on marine nematodes from the Gulf of Naples (DE MAN, 1876—c), his earlier papers (1876—a, 1880, 1881 and 1884) are devoted to the free-living, soil and freshwater nematodes of the Netherlands, while his later publications also deal with marine forms and are not confined to the Dutch fauna. |

| There comes a time in the history of nearly every genus when it becomes almost immoral to add new species without first having surveyed the genus as a whole. Dendrophthora has reached this state. From the time of its first recognition as a separate entity to the present, new species have been described, often on very tenuous grounds, and usually without an indication of infrageneric relationships, until today we are faced with a staggering mass of specific epithets in complete chaos. The genus has not been comprehensively studied for more than half a century, and no balanced attempt has as yet been made to establish natural divisions within. Having become interested in the morphology of this and the related genus Phoradendron (KUIJT, 1959), I was naturally... |

| Während eines Studienaufenthaltes an der Station Internationale de Géobotanique Méditerranéenne et Alpine in Montpellier, Direktor Professor J. Braun-Blanquet, wurden vom Verfasser in Süd-frankreich, (Languedoc), in den Weinbergen der Umgebung Montpelliers sowie im Departement Pyrenees Orientales 72 pflanzensoziologische Aufnahmen gemacht. Nach J. Braun-Blanquet gehört die Vegetation der Weinberge des Languedoc zu der Assoziation Diplotaxidetum erucoidis (Br.- Bl. 1931). J. Braun-Blanquet hat hauptsächlich in den Jahren 1929-1938 in den Weinbergen des Languedoc 36, noch nicht publizierte, Aufnahmen gemacht; später, 1949—1952, kamen noch einige weitere hinzu. Es handelt sich dabei fast ausschliesslich um Herbst-Aufnahmen. In der ersten Periode: 2 Aufnahmen... |

| In this second paper the red beds outcropping in the northern part of the Duero basin have been treated regarding their mineral and pebble composition, chemical parameters, and surface textures of quartz sand grains, taking as basis the results reported in the first paper. These deposits originate from soils in the source area, and have been rapidly supplied into the basin by braiding rivers. Heavy mineral associations and pebble composition prove the source area to be lying north and west of the area of deposition. Ferric iron oxides, clay mineral associations, and hydrogen ion concentrations point to a red soil formation in the source area which had not yet attained the laterite stage, but which had already suffered alkaline leaching. The presence of... |

| The Acarids described in the present paper comprised a small collection made by Dr. L. v. d. Hammen of the Leiden Museum during a visit to Biak Island, Netherlands New Guinea in 1953. The mites were found inhabiting the Cladophora socialis and Red Algae on the stones in the intertidal zone near the Royal Netherlands Naval Base on the south coast of the Island, and were sorted out from a large collection of other small arthropods obtained from a large sample of algae by means of a modified Tullgren apparatus. The actual biotope in which they occured is very fully described in Dr. v. d. Hammen's recent paper 1) in which he describes a new genus and species of Oribatid mite from a single specimen. The rest of the Acarids, Dr. v. d. Hammen has very kindly... |

| This paper deals with the Opisthobranchia collected by the Netherlands Biological Expedition to Turkey 1959. The collection is deposited in the Rijksmuseum van Natuurlijke Historie at Leiden. The material was chiefly collected in three areas, viz. the Bay of Antalya and the Bay of Mersin (formerly Içel), both in the Eastern Mediterranean on the south coast of Turkey, and the environs of Trabzon on the southeast coast of the Black Sea. The collection is rather small, comprising 25 species, which is probably only a fraction of the total Opisthobranchiate fauna of Turkey. Of course most of these species have also been recorded from the much better known Western Mediterranean. All the same, examination of the collection yielded some surprising facts. To my... |

| Trifolium ornithopodioides L. is bekend van een tweetal plaatsen op Walcheren, nl. van Oranjezon en van Oostkapelle (zie lijst De Levende Natuur 61, 1958, p. 138). De heer A. de Visser (St. Laurens) deelde ons mede, dat de vindplaats bij het pompstation Oranjezon onlangs volkomen vernietigd werd doordat het terrein door bulldozers werd geëgaliseerd voor de aanleg van een kampeerterrein. v. O. en R. Ajuga pyramidalis L. Deze soort werd in 1958 in enkele exemplaren gevonden door W. J. de Munk in de Provinciale Waterleidingduinen bij „De Brabantse Landbouw”, gem. Castricum, waarschijnlijk aangevoerd met fazantenvoer. Bij een bezoek, dat wij op 29 mei j.l. aan genoemde duinen brachten, werd deze vindplaats ons getoond door de heer E. J. Kortenoever.

| INTRODUCTION The fossil remains of Hippopotamus from the Pleistocene "Elandsfontein" site near Hopefield, Cape Province, have already been briefly described by Singer and Keen (1955), who found that the material available at the time was not different from the living Hippopotamus amphibius L. However, it seems worthwhile to review their status since the Hippopotamus material has been considerably increased as a result of recent collecting trips to the site. Not only are there now cranial remains, but also postcranial material, notably carpals, tarsals and metapodials. The purpose of the present note is to place on record all the material at present in the Hopefield collection pertaining to the species in question. The specimens, originally housed in the... |

| Beschreibung der Geburt von drei Frettchen mit drei Protokollen. In mancher Hinsicht etwa die gleichen Befunde wie MURR (1932). Hier werden nur die abweichenden und neuen Befunde mitgeteilt. 1. Keine Unterschiede zwischen primiparen und pluriparen Tieren. 2. Eine glasige Schleimschnur aus der Vulva ist 2 bis 4 Stunden vor der Austreibung wahrnehmbar. Kurz vor der Geburt steht das Muttertier nur mit grösster Schwierigkeit und liegt oftmals auf dem Rücken. 3. Die Austreibung fängt an mit Pressen. Das Tier nimmt dazu die charakteristische Kothaltung an und geht in die Kotecke. 4. Nachdem die Fruchtblase in der Vulva erschienen ist, wird sie vom Muttertier mit dem Gebiss zerrissen. Nur ausnahmsweise findet ein spontaner Blasensprung statt. 5. Das Junge wird im... |

| Pheretima long has been known to have more species than any other oligochaete genus though no one has yet been in a position to determine how many of them have any real claim to recognition even as old-fashioned museum taxa. Intrageneric relationships are unknown primarily because somatic anatomy was derogated in the classical system of the Oligochaeta. Accordingly, if one wishes to learn whether any specimen at hand is of a known or undescribed taxon it is necessary, first of all, to check through appropriate portions of a 16-page table in Michaelsen's monograph (1900) where species are grouped according to location of the spermathecal pores. If identification is impossible, as often must be the case, a laborious search through the literature of the last... |

| The data used in this paper have been mainly collected during prolonged investigations of the forest fauna of Java, particularly with regard to insect species of some economic or silvicultural importance (see KALSHOVEN, 1955). This explains why some special attention has been paid to weevils damaging the rattan palms, a source of very valuable secondary forest produce in the East, as well as to those living on the bamboos, often growing wild or semi-wild in the forests, and to certain species occurring on Zingiberaceae, which plants are such a common feature of the oriental forest vegetation. These investigations formed only a side-line of the programme of forest entomological work and inevitably only yielded fragmentary data, but they could be... |
