| Dix espèces de Copépodes Cyclopoïdes siphonostomes ont été recueillies à l’Ile Maurice. Parmi ces espèces, huit sont nouvelles pour la science; un genre nouveau (Monocheres), appartenant à la famille des Asterocheridae, a été créé pour une de ces espèces (M. mauritianus). Les autres espèces nouvelles sont Asterocheres halichondriae, A. genodon, A. proboscideus, Asteropontius corallophilus, Acontiophorus brevifurcatus, Bradypontius pichoni et Pteropontius pediculus. Deux espèces, Asterocheres mucronipes et Myzopontius australis, étaient déjà connues, la première de la Méditerranée occidentale, la deuxième de l’Australie. |

| Being occupied with studies on the Convolvulaceae of Netherlands India I met with a remarkable specimen in the Buitenzorg Herbarium, collected by Dr. O. POSTHUMUS during the expedition in Djambi (Sumatra) in the year 1925. At first sight this plant seemed to be a Merremia. A closer examination, however, soon showed some important differences with that genus, especially in respect to the corolla, which has a long, narrow and rather fleshy tube and a limb with 5 short, reflexed (or patent?) lobes. Each lobe is deeply bifid, so that the limb appears 10-lobed. The middle part of the lobes is fleshy just as the tube; it corresponds with a midpetaline field of the corolla of most genera of Convolvulaceae, the lateral parts of the lobes (lobules) are much... |

| In this book a number of general topics of island biogeography are discussed mainly on the basis of case studies dealing with three archipelagos: The Hawaiian Islands (two chapters); the Juan Fernandez Islands (three chapters) and the Bonin (Ogasawara) Islands (three chapters). Two chapters deal with, respectively, Ullung Island and the South Pacific Islands. The remaining three chapters are all part of the section on general evolutionary patterns and processes. Except in some of these last chapters, there are no references to islands outside the Pacific Basin. The depth of treatments ranges from general discussions based primarily on literature studies (such as G. D. Carr’s discussion of chromosome evolution in Hawaiian flowering plants, which is nearly... |

| The present paper deals with the results of my investigations regarding the tenebrionid beetles of the Antilles, north of Trinidad. For this work, use has been made of the magnificent collections assembled by Dr. P. WAGENAAR HUMMELINCK, of a number of specimens gathered by Dr. H. J. MAC GILLAVRY as a student member of a geological excursion to Cuba that took place in 1933 under the direction of Prof. L. M. R. RUTTEN, and also of materials belonging to several European museums. In particular, I have examined specimens in the British Museum (N.H.); the Natural History Museum at Paris; the Natural History Museum of Amsterdam; the State Museum of Zoology, Munich; the G. Frey Entomological Museum, Munich; and lastly the Museum of Zoology of the University of... |

| Seven new species and one new subspecies of the genus Strandesia s.l. Stuhlmann, 1888, are described. Four species reared by Sars (1901) from dried mud from Brazil are redescribed. The genera Acanthocypris Claus, 1892, and Neocypris Sars, 1901, are considered as subgenera of Strandesia s.l. Two species from Europe, formerly attributed to Cypricercus Sars, 1895, are redescribed. One of these, C. obliquus (Brady, 1868) was used as type-species for the erection of a new tribe and of the genus Bradleycypris by McKenzie (1982), but proves to be a member of the subgenus Neocypris of Strandesia s.l. Therefore Bradleycypris becomes a subjective synonym of Neocypris. On the other hand, Cypricercus fuscatus (Jurine, 1820) effectively shows the characters used by... |

| 1. L’été de 1923 j’avais l’occasion de visiter l’herbier du British Muséum à Londres et celui de WALLICH dans les royal botanical Gardens of Kew près de Londres. Et je pouvais constater que le no. 1163 du catalogue WALLICH (1829) est vraiment notre Walikoekoen. Tous les exemplaires de WALLICH sont provenus d’un ou de plusieurs arbres dans le jardin botanique de Calcutta où l’espèce avait été introduite en 1816 par le Dr. BURKE de l’île de France (Mauritius) d’après une note dans le catalogue de WALLICH ¹) du honorable Company’s botanical Garden Sibpur near Calcutta vol. II p. 838, comme M. le superintendent de ce jardin a bien voulu me rapporter. Le superintendent ne savais pas m’expliquer comment l’espèce avait été portée à Mauritius de l’île de Java (son... |

| The author deals with taxonomy, character variation, phylogeny and biogeography of Heterometrus, a scorpion genus occurring in Southeast Asia. The taxonomic value of 131 characters is studied, including 75 biometric ones; 72 characters are selected to be used in the present revision for purposes of classification. In the numerical analysis and in the study of descriptive characters, specimens are clustered polythetically; this method allows variation as observed in the taxa, the sharing of the total set of taxon characteristics not being absolutely required. A total of 21 species (4 new) and 31 subspecies (16 new) are discriminated, classified in five subgenera, two of which are new. The African genus Pandinus Thorell is... |

| Amidst sponges, recently collected by my friend Mr. P. J. Buitendijk in the bay of Batavia, I met with a Polychaeteworm, obviously belonging to the genus Bhawania of Schmarda 1). Though I cannot give full information about its structure, because I had only a single specimen at my disposal with its head so far withdrawn that it was quite invisible, nevertheless I think the present communication not without interest, since Schmarda’s description is rather incomplete and there still reigns a good deal of uncertainty about the affinity of the paleae-bearing Polychaetae. It is a slender, flattened worm, measuring 25 mm. in length and 1½ mm. in breadth; the body is only slightly tapering at its anal extremity and has about 175 segments. Its colour is yellowish... |

| The paper summarizes the current understanding of the evolution and diversification of birds. New insights into this field have mainly come from two fundamentally different, but complementary sources of information: the many newly discovered Mesozoic bird fossils and the wealth of genetic analyses of living birds at various taxonomic levels. The birds have evolved from theropod dinosaurs from which they can be defined by but a few morphological characters. The early evolutionary history of the group is characterized by the extinctions of many major clades by the end of the Cretaceous, and by several periods of rapid radiations and speciation. Recent years have seen a growing consensus about the higher- level relationships among living birds, at least as... |

| Contrary to Kern & Reichgelt (1954) it is concluded that both C. reichenbachii and C. ligerica can not be distinguished from C. arenaria in the Netherlands. The paper deals with the results of a reexamination of some collections identified by Kern and Reichgelt. The collections have especially been examined on the distribution of the sexes in the inflorescence (fig. 1: complete inflorescences, male flowers in solid dots, female ones in circles), form of the achenes (fig. 2), diameter of the rhizomes (fig. 3), width of the leaves (fig. 4). Within subg. Vignea C. arenaria s. lat. can be characterized by middle partial inflorescences which have male flowers both in basal and in apical position, and by long rhizomes. It is concluded that no taxonomically... |

| The wood structure of 71 species representing 24 genera of the pantropical Lecythidaceae s.l., including the edible Brazil nuts (Bertholletia excelsa) and the spectacular cannon-ball tree (Couroupita guianensis), was investigated using light and scanning electron microscopy. This study focused on finding phylogenetically informative characters to help elucidate any obscure evolutionary patterns within the family. The earliest diverging subfamily Napoleonaeoideae has mixed simple/scalariform vessel perforations, scalariform vessel-ray pitting, and high multiseriate rays, all features that are also present in Scytopetaloideae. The wood structure of Napoleonaea is distinct, but its supposed close relative Crateranthus strongly resembles Scytopetaloideae. The... |

| We describe a possible new defensive behaviour of larval stages of mantis shrimps (Stomatopoda). Mantis shrimp larvae are rarely observed in nature, thus the study is based on postures of museum material and functional morphological aspects. Specimens described here are tightly enrolled, their pleon is bent forward,and the telson is locked into the frontal margin of the shield. This margin has two lobes into which the two posterolateral spines of the telson fit. The shield shows further adaptions to enrolment; e.g., the ventral gape of the shield perfectly matches the width of the pleon and leaves no major gaps when the pleon is bent forward. Based on these observations, we briefly discuss the possibilities to infer behavioural aspects from functional... |
