| L'utilisation rationnelle des déchets et sous-produits de la pêche est pour les diverses industries de la pêche maritime un problème très important car ces déchets et sous-produits constituent souvent plus d'un tiers du poids total des produits débarqués sur notre littoral.Dès son origine, l'Office s'est attaché à ce problème et, de 1924 à 1939, a divulgué dans ses publications les résultats pratiques sur la fabrication et l'utilisation des farines, engrais et huiles de poissons et autres animaux marins, des glues et colles de poisson, des essences d'orient, etc. [OCR NON CONTRÔLE] |

| Les claires situées sur les deux rives de la Seudre, sur les côtes de Marennes, du Chapus et de l'Ile d'Oléron, sont des bassins creusés dans des terrains argileux. Elles sont alimentées en eau de mer par un système de chenaux et de ruissons, leurs affluents, pour un coefficient de marée en général égal ou supérieur à 70. Dans certaines claires, les ostréiculteurs déposent, au mois de Mai, des huîtres plates originaires de Bretagne ou d'Arcachon, âgées de trois ou quatre ans, à raison de 2, 3 et 4 huîtres par mètre carré. Dans ce milieu, sous quarante centimètres d'eau, elles vont pendant six ou sept mois, croître, engraisser et verdir. |

| L'importance économique du Germon (Germo alalonga, Gmelin), dont la pêche saisonnière se pratique de juin à octobre au large des côtes atlantiques françaises, était telle pour l'armement qui la pratique et pour l'industrie de la conserve qui en vit que, dès sa création l'Office Scientifique et Technique des Pêches Maritimes devait s'attacher à la biologie encore mal connue de ce poisson.

| 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,... |

| Although from 1255 up till now about 47 Physeter macrocephalus have been cast upon the coast of the Netherlands, or have come ashore alive, but very few materials have been preserved and we are in the possession of only two specimens, those of 1937, the complete skeletons of which are preserved in the Rijksmuseum van Natuurlijke Historie, Leiden. Apart from these skeletons the following fragments are preserved : 1. The damaged upper part of the skull and three vertebrae from the animal of Scheveningen, 1617. These fragments are in the possession of the Dutch Protestant Church, Keizerstraat, Scheveningen (Van Deinse, 1918, p. 42, etc., and Plate IV). 2. The left humerus, radius, and ulna, grown together, probably from the same specimen as no. 1. This bone... |

| Ch. I. The environment of the Dutch Wadden Sea, as well as that of the estuaries in the southwestern part of the Netherlands can be divided into three sub-zones: (1) the channel floors (sensu lato), i.e. the areas below mean low tide level, (2) the tidal flats (sensu stricto), between the levels of mean low and mean high water and, (3) the salt marshes, above the level of mean high tide. The channel floors are composed, either of older sediments, which have been laid bare by erosion of the tidal currents, or by new deposits, formed in the channels themselves. The latter are predominantly of sandy character, but may show locally high contents of muddy material, especially in sheltered bays. The tidal flats consist for the greater part of sand. Slightly... |

| Hooijer, D.A.. |
| The species mentioned in the title of the present contribution was first described on the base of two incomplete upper molars, some fragments, and two portions of limb bones (Hooijer, 1949). The two and only complete molars were described later (Hooijer, 1953a). To this has been added the description of the milk dentition and of three premolars (Hooijer, 1953c). There are, however, important lacunae in our knowledge of the molar dentition to be filled. It remains as yet uncertain whether the type upper molar of 1949 represents M2 or M3, while the smaller of the complete lower molars of 1953 could be either M1 or M2. The prolonged study of the fragmentary molars in the Celebes collection has now made it possible to assemble the full set of upper and lower... |

| Les Copépodes commensaux et parasites d’Invertébrés, quoique très communs dans toutes les mers, sont peu connus. En vérité, on en a décrit un nombre assez grand de genres et d’espèces, mais les descriptions sont trop souvent superficielles, voire même erronnées. Un de ces genres très peu connu est Tococheres, établi par le Professeur Paul Pelseneer, 1929, pour un Copépode trouvé sur les branchies de Loripes lacteus. Bivalve récolté dans l’Aber de Roscoff (Bretagne). La description de Pelseneer ne donne d’informations que sur la forme generale de la femelle, sur les antennules et sur la cinquième paire de pattes. On ne sait absolument rien sur l’antenne, les pièces buccales et les 4 paires antérieures de pattes thoraciques. |

| OLETHREUTINAE (Eucosmidae auct., Eucosminae auct.) Introduction The study of the South Asiatic representatives of the subfamily Olethreutinae of the Tortricidae is difficult on account of various reasons. Our basic knowledge of this group of insects originates from the knowledge of the Palaearctic fauna; unfortunately the taxonomy, and especially the nomenclature of the European Olethreutinae has for a long time been in a deplorable state of confusion and only recent pioneer work along modern lines, chiefly by Obraztsov, leads to some order. Unavoidably this confusion throws a shadow upon the study of the Olethreutinae from other regions than the Palaearctis. Since genital characters are of cardinal importance for the classification of the genera and... |

| It is well known that the main functional components of the skull in the Whalebone Whales (Mystacoceti) attain an ultimate size, which is out of normal proportion to the rest of the skeleton as compared to the proportions existing in land-mammals. As generally supposed the aquatic mode of life has greatly influenced the shape of the skull. Therefore, it is to be expected that the various species, which all have the same mode of life, show a certain amount of convergence. However, not all bones have become enlarged to the same degree; e.g., the alisphenoid and the orbitosphenoid have remained relatively small. Apparently these bones of the orbit have not been influenced by the aquatic mode of life to the same extent as is the case with other elements of the... |

| Of this series of preparations to the definite publication of the Burseraceae in “Flora Malesiana”, the present part is giving an additional note on VI. Garuga and dealing with the genera VII. Triomma, VIII. Dacryodes and IX. Santiria (and a new combination in Protium). The present paper gives only additions to and alterations of Lam’s monograph (H. J. Lam, Bull. Jard. Bot. Buitenz., Sér. 3, 12, 1932, 281— 561); descriptions, synonyms, litterature, specimens cited, ecological and other notes are only mentioned insofar as they are not given by Lam. |

| The Netherlands Antilles may be divided into: (1) The Curaçao Group (or Netherlands Leeward Islands): Curaçao, Aruba and Bonaire. (2) The St. Martin Group (or Netherlands Windward Islands): (Netherlands) St. Maarten, Saba and St. Eustatius. The latter islands are very small, forming together only 8.1 per cent of the total area of the Netherlands Antilles, and 2.2 per cent of its population. The Curaçao Group often has a desert-like aspect with a “tropical dry-forest” vegetation. Therefore on these islands the mosquito pest is nothing like so bad as it usually is in the tropics. There are few permanent breeding places, except man-made receptacles in and around the houses to store rainwater or well-water in as the Government waterworks do not always produce... |

| The present paper deals with the results of my investigations on the Tenebrionidae of the Leeward Group and the xerophilous regions of Venezuela and Colombia. I am much indebted to Dr P. Wagenaar Hummelinck for giving me the opportunity to study the material he collected during his trips to this area. Some other specimens used were collected by the present writer himself. Material for comparison has been obtained through the courtesy of several people, particularly the Director of the British Museum (N.H.), Mr H. Kulzer (Frey collection, Munich), and Prof. E. Tortonese (Museum of Zoology, Turin University), to all of whom I am deeply obliged. In particular I also wish to thank Prof. E. Gridelli, Director of the Natural History Museum, Trieste, to whom I am... |

| In 1950 I received from Mr. D. Hille Ris Lambers a strange Pseudococcid from Java which had been collected by Mr. F. W. Rappard, a senior forestry officer, who regularly collects aphids for Mr. Hille Ris Lambers on his tours of duty. As this insect was a coccid, it was transmitted to me for examination. Its appearance is quite abnormal; the shape of its body reminds one almost of a large mite (fig. 4). The 6-segmented antennae have a dense vestiture of fine hairs, with exception of the 2 first segments which are very short. A tuft of 5 very long setae is present on the top of each of the anal lobes. The ungual digitules are extremely large and very flat. It was only after close study that the insect was recognized as a Pseudococcid. It has 2 pairs of... |

| During the study of the Xyridaceae of the Malaysian area it was desirable to study those of Australia and Continental Asia as well. The Malaysian species now have, in the meantime, been published (Flora Malesiana, ser. 1, 4, 1953, 366—376). To the new taxa described in Blumea 7, 1953, 307—308 the Latin diagnoses of the following new species and a new section may here be added: 1. Xyris linifolia van Royen, nov. spec. — Fig. 1. Herba mediocris, ad 40 cm alta. Folia subulata, ad 25 cm longa, c. 1 cm diam., subfalcata, acuta, sparse papillata; vaginae 6—8 cm longae, basi 3—6 mm latae; ligula brevis acuta c. 1 mm longa.

| I. INTRODUCTION In the last tens of years more and more attention has been paid to the much neglected and ignored publications written by the eccentric early American naturalist Constantine Samuel Rafinesque. Until now, however, Rafinesque's work in the field of carcinology has received but little attention from modern authors. In 1905 Ortmann (1905, p. 107) pointed out that the name Astacus limosus Rafinesque, 1817, is older than the name Astacus affinis Say, 1817, for the same species, and that consequently the former name has to be used. In the same year Richardson (1905, p. 10) replaced the invalid generic name Ligia Fabricius, 1798, by Ligyda Rafinesque, 1815. M. J. Rathbun (1937, p. 63) substituted the generic name Thelxiope Rafinesque, 1814, for the... |
