| The species of Lestes from Surinam are treated. L. basidens spec. nov. (♂ holotype: Distr. Nickerie, Sipaliwini, near airstrip), L. curvatus spec. nov. (♂ holotype: Distr. Suriname, Coropina creek, Republiek), L. edentatus spec. nov. (♂ holotype: Distr. Marowijne, Nassau mountain range) and L. trichonus spec. nov. (♀ holotype: Distr. Nickerie, Sipaliwini, near airstrip) are described and illustrated. The types are deposited in the National Museum of Natural History, Leiden. L. mediorufus Calvert and L. tenuatus Rambur are illustrated and a lectotype for the latter species is designated. The holotype of L. sublatus Hagen in Selys is redescribed and illustrated. L. forficula Rambur, known from the surrounding countries of Surinam, is also illustrated. A key... |

| Whilst studying the material of the genus Securidaca for the “Flora of Suriname”, I found it in most cases extremely difficult or even impossible to identify the species. The original descriptions are, as a rule, very short, and they have been based for a good deal on incomplete material: mature fruits, for instance, are often missing. Hence it is not surprising that on quite a number of species the opinions of taxonomists disagree. Accordingly on the one hand we may find in the various collections the most different species lumped together under the same name, while on the other hand one and the same species may appear under several names. A study of the type specimens therefore, was obviously very desirable. I am indebted to the “VAN EEDEN FONDS” for... |

| Pinkster, Sjouk. |
| The morphological diversity within the species Echinogammarus berilloni (Catta, 1878), stressed by Spandl (1926), Margalef (1956) and Pinkster (1969) was a motive to sample systematically in drainage systems of the Iberian peninsula and of great parts of France. It became clear that E. berilloni in reality was the collective name for a group of at least 10 species, all of them with their own, restricted distribution area. Only one of these species, the real E. berilloni, inhabits a much larger area, including the major part of France, the Channel islands, Belgium, Luxembourg, the southern part of the Netherlands, and south-western Germany. In this study the characters of the E. berilloni-group are discussed and comparative descriptions are given of all... |

| Since the publication of my revision of the Vespinae of the Indo-Malayan and Papuan areas (1957), I have had the opportunity to study a considerable amount of additional material of this subfamily. Part of this material originated from the areas treated in my previous paper, and in so far as the following notes refer to these specimens, they may be regarded as a first supplement to that revision. The present paper, however, also contains some information on the Vespinae occurring in India, China, and Japan. At first I had hoped to round off my studies of the Vespinae by preparing a more or less complete revision of the Vespa species of the Asiatic continent, but so far it has proved impossible to accumulate sufficient material for this purpose. The males... |

| Pteridological Notes, 3 The genus Polypodium in the Netherlands Both Polypodium vulgare L. (sensu stricto) and P. interjectum Shivas occur in the Netherlands. Most of the differential characters reported in the literature overlap one another rather broadly, so that it is often necessary to use a ’syndrome’ of characters for the naming of individual specimens. The results obtained by the present authors do not correspond with those of SHIVAS (22), ROTHMALER & SCHNEIDER (18), or LENSKI (11) in every respect. The two forms appear to differ in the following features: P. vulgare: Frond lanceolate in outline with the lower pairs of pinnae approximately of equal length along a considerable portion of the frond blade, and the apical part often gradually... |

| The application of modern techniques in histochemistry, electron microscopy, physiology, biochemistry, molecular biology, etc. in the last decades has changed embryology from a descriptive science to an experimental and applied science. The present book is a result of this development. A score of authors deals with all aspects of embryology from male and female gametogenesis to fruits and seeds. Amongst the topics discussed in this volume are: male and female sporogenesis, fertilisation (in vivo and in vitro), zygotic and somatic embryogenesis, endosperm development, maturation, germination and dormancy of seeds. Some of the more special subjects are apomixis and parthenocarpy. |

| The readers of my work entitled “Muséum des Pays-Bas” will recollect that I identified with the Gallinula olivacea of Meyen, inhabiting the Philippine islands, a bird collected by the late Dr. Bernstein, in the islands of Halmahera and Ternate, and which was afterwards stated to live equally in the isles of Amboina and Mysole. This bird was designated by me as belonging to a particular subdivision characterized by its very small triangular frontal plate. Mr. Frank, the well known dealer in zoological objects at Amsterdam, a man who, during more than half a century, with an unaltered integrity, has procured for our Museum many thousands of the most valuable objects, sent to me the skin of a bird, recently collected in New-Guinea, which appears to belong to... |

| p. 562 line 14 add: — Luteidiscus St. John, Bot. Jahrb. 94 (1974) 549. Remark: St. John described the new genus Luteidiscus, which differs from Tetramolopium only by the colour of the corolla of the disc-flowers, being yellow in Luteidiscus and purplish in Tetramolopium. When considering the colour in the New Guinea species of Tetramolopium as given by the collectors we find for T. macrum (F. v. M.) Mattfeld var. macrum (dark-)yellow, (dark-)yellowish-brown, (pale-)purple, or purplish (Koster in Nova Guinea, Bot. 24, 1966: 571); for T. macrum var. album Koster purple, purplish, purple-brown, brown, (pale-)yellow with brown tips, dark- or yellowish-brown (l.c. 572); for T. macrum var. glabrescens Koster (light-)yellow, light brownish-purple, lobes with... |

| Fossil Hystrix material from a large number of localities is biometrically analysed and compared with the extant species. H. major, H. etrusca, H. makapensis, and H. angressi are shown to be junior synonyms of H. refossa. H. bessarabica and H. trofimovi are shown to be junior synonyms of H. primigenia, and H. schaubi and H. cristata minor of H. vinogradovi. The dental characteristics of H. refossa, H. primigenia and H. vinogradovi are discussed. |

| During a short stay at Bangkok on December 3rd, 1953, Professor H. Boschma observed that enormous quantities of minute insects were attracted by lamplight in the hotel of the Royal Dutch Airlines (K.L.M.) "Plaswijk" at the airport Laksi. From the enormous accumulations of these insects around the lamps he collected a sample which he entrusted to me for examination. This sample proved to consist almost entirely of a new species of mayfly which is described in the present paper. Caenis demoulini nov. spec. Female imago. Head and thorax uniformly yellowish brown. Eyes purple-black, prominent. Antennae grey-brown ; median ocellus prominent, colour light brown with a darker edge. Abdomen pale yellowish brown, at the dorsal surface with light browngrey markings,... |

| Three plant-inhabiting fungi with tetraradiate conidia, Tricornispora bambusae Bonar, Fumagopsis triglifioides Speg., and Eriosporella calami (Niessl) Höhn., the type species of monotypic genera, are redescribed and illustrated from type specimens. These genera are regarded as distinct. Fumagopsis is possibly closely related to Kazulia Nag Raj. Since the type specimen of Tridentaria Preuss did not bear a fungus which agreed with the very brief original description, the genus Tridentaria Preuss is regarded as doubtful. The nematode-trapping Hyphomycetes formerly placed in Tridentaria should be reclassified. |
