| Owing to their limited possibilities for either active or passive dispersal, their association with the soil habitat, their vulnerability towards a dry atmosphere, and, in fact, on account of their general ecology and ethology, Diplopoda among arthropods are surely one of the most important classes in relation to the study of historical biogeography. For the class as a whole the sea appears to be an unsuperable barrier as is proved by the almost complete absence of endemic taxa on oceanic islands. In many cases lowland plains also act as severe obstacles against the dispersal of millipedes. The presence or absence of diplopods on islands or continents, therefore, may give a strong argument in favour or against any supposed former land connection. The long... |

| Piptochaetium was described in the year 1830 by Presl as a monotypic genus; the only species was named and figured by him as Piptochaetium setifolium, an inhabitant of Peru. The genus has usually been included as a section in the genus Oryzopsis of Michaux, and various species were also published under the genus Stipa. In my monograph of the genus Aristida I had the opportunity to study the whole tribe of the Stipeae, and reasons are given there why Piptochaetium should be accepted-as a quite distinct genus. From the very good description given by Presl and from the accompanying plate, the genus is easily recognizable. In my monograph a key to the genera of the tribe of the Stipeae has been given. The genus Piptochaetium is limited to the new world. In... |

| Dissolution of algal limestones in a 1-10% HCL solution delivers flocks of well preserved non-calcareous algae and sometimes some other plant remains as well. Non-calcareous algae of Cambrian, Carboniferous, Jurassic and Paleogene age were obtained in this manner. Slides of these fossils together with thin sections of the limestones are shown. Various algal divisions are represented: Cyanophycophyta, Chlorophycophyta, Xanthophycophyta and Rhodophycophyta. |

| Between 22 February and 18 March 1985 the Kew Assistants’ Expedition was held. Members were Ms. F. BOOTH, Ms. L. FITT, Ms. S. OLDRIDGE, Ms. B. SWAIN, Mr. D. COOKE, Mr. P. EDWARDS and Mr. B. STANNARD under the guidance of Dr. B. CROXALL, Dr. S. DRANSFIELD and Dr. J. DRANSFIELD. Between February and March 1985 Dr. B.S. PARRIS and Mr. P.J. EDWARDS (K) collected pteridophytes at Taman Negara, Genting Highlands, Pasoh and Fraser’s Hill-top. The main set is in K with duplicates at KEP and UKMB. |

| All 168 known species within the 6 genera of the caddisfly family Helicopsychidae are cataloged. Included are all synonyms, type localities, type depositories and species ranges. A historical summary of the taxonomy used within the family is given as well as the biology of the different life stages on generic level. Due to uncertain taxonomic position Helicopsyche helicoidella (Vallot, 1855), Helicopsyche pupoidea (Gould, 1864), Helicopsyche scalaris Hagen, 1864, Helicopsyche thelidomus Hagen, 1864, Helicopsyche arenifera (Lea, 1834), Helicopsyche braziliensis (Swainson, 1840) and Helicopsyche colombiensis von Siebold, 1856 are not included in the catalog. Helicopsyche fannii Rougemont, 1879 was never described and is listed as nomen nudum. Helicopsyche... |

| The chirostyloid squat lobster Pristinaspina gelasina from the Upper Cretaceous of Alaska is most closely related to members of the genus Kiwa (Kiwaidae) as indicated by the presence of supraocular spines, a medially carinate rostrum and similar carapace groove patterns. Evidence from morphology, stratigraphic position and molecular divergence estimates of extant chirostyloids supports its position in the stem of Kiwaidae. Pristinaspina, however, also differs significantly from kiwaids and is here assigned to a new family, Pristinaspinidae. The chief distinction between the free-living pristinaspinids and vent- or seep-associated kiwaids (and an important synapomorphy of the latter) is the enlargement of the metabranchial regions in kiwaids, which meet in... |

Pteridophyta, Gymnospermae, Angiospermae (Lauraceae- Euphorbiaceae), Madrid, 2001, 770 pag. + bijlagen, geïll. met lijntekeningen, ISBN 84-00-07933-7, € 24, uitgave van de Koninklijke Botanische Tuin. De eerste 8 delen van de Flora iberica zijn gecomprimeerd in een enkel boekje dat qua formaat en indeling op de Heukels lijkt. Het boek bevat alle originele illustraties, nu echter op ongeveer een kwart van het oorspronkelijke formaat afgedrukt. In feite hebben we te maken met een tweede editie van de delen 1—8 van Flora iberica, maar dan zonder de beschrijvingen. Een flink aantal nieuwe soorten zijn toegevoegd en de verspreidingsgegevens zijn... |

| The coral-eating barnacle Hoekia monticulariae (Gray, 1831), the only internal parasite among the Thoracica described to this day, is characterized by an irregularly-shaped shell nestled cryptically between the polyps of the hermatypic coral Hydnophora Fischer, 1807, which occurs throughout most of the Indo-West Pacific. Because of its protean form, cirripedologists have failed to appreciate the diversity of taxa related to Hoekia, , a presumed monotypic genus. We describe seven new species divided between Hoekia and three new genera, Eohoekia, Parahoekia, and Ahoekia for which the Tribe Hoekiini is proposed. As in other pyrgomatids, calcareous overgrowth by the coral is inhibited around the edge of the wall and aperture. But in Hoekiini a pseudopolyp,... |

| In 1935 the present author reported the occurrence of this N. American species in the eastern part of Holland, province of Overijssel, in the vicinity of Almelo (JONKER, 1935). He found the species near the hamlet of Harbrinkhoek on a wet heath. The locality was also the only station of Wahlenbergia hederacea in the Netherlands, discovered a year before. Notwithstanding the extensive reclamations in that part of the country the species now still occurs in a number of localities around Almelo. The plants cannot be considered adventitious as they were found in places that are comparatively little influenced by human culture, judging from the occurrence, on the first-discovered locality, of e.g. Wahlenbergia hederacea. Gentiana pneumonanthe, Viola palustris,... |

| Mantra speciosa Leigh-Sharpe, 1934 (ex Poecilostomatoida), collected during the Siboga Expedition is redescribed on the basis of the holotype female. The 15-segmented antennule and the gnathostomous nature of the mouthparts exclude the Mantridae from the Poecilostomatoida and point to a relationship with the tunicate-infesting families Ascidicolidae, Notodelphyidae and Archinotodelphyidae (Cyclopoida). Nearchinotodelphys indicus Ummerkutty, 1960 (ex Archinotodelphyidae) is transferred to the Mantridae. It is suggested that the bivalveinhabiting mantrids have diverged from the ascidicolous lineage leading to the Notodelphyidae and Ascidicolidae. |

| A characteristic feature of the liverwort cell is the presence of “oil bodies”. Chemically they are made up of rather volatile terpenoids, mainly sesquiterpenes and their derivatives (Suire 1975) which seem to be surrounded by a membrane. The nature of this membrane is still unknown. Through the light microscope the oil bodies appear as colourless, rarely brownish or blueish organelles in the cytoplasm, showing great variation in shape, size, number and structure. The morphological characteristics of the oil bodies, which have been studied over 80% of the genera of Hepaticae, have been shown to be taxonomically significant (cf. Schuster 1966). While in the subclass Marchantiidae they are restricted to special, chloroplast-free “oil cells” of the... |

| On September 21st last Professor Dr. E. D. van Oort died at Leiden rather suddenly. For a considerable time his health had, indeed, been indifferent; on frequent occasions he had been unwell for shorter or longer periods, and in the spring of this year he was even obliged to apply for a four months' leave of absence. When after the expiry of this period, apparently recovered, he resumed his work, be it only for a few hours daily, we fostered the hope to have him among us for many years to come. Fate, however, decided differently. On Thursday morning he came to the museum, feeling better than on the previous days; he received the visitors cheerfully, and left the building past noon. Three hours later death had overtaken him. Eduard Daniel van Oort was born... |
