| Most classifications of the genera of the Gramineae have been on the structure and arrangement of their spikelets, for these organs provide a far greater variety of readily distinguishing characters than do other parts of the grass plant. Nevertheless it has not always been possible to decide from morphological studies alone whether marked similarities in structure point to a close affinity or are merely examples of parallel development. The modern taxonomist, endeavouring to arrange the grass genera in as natural a sequence as possible in order to emphasise relationships and evolutionary trends, sooner or later meets with difficulties in this respect, for examples of parallelism are of common occurrence in this family. He is more fortunate, however, than... |

| A few years ago Prof. Dr W. Martin, at the time director of the Gallery of prints and drawings at Leyden, drew my attention to an oilpainting at Prof. J. N. Bakhuizen van den Brink’s, 40 Rapenburg, Leyden. This painting (size 95 X 68 cm), which is owned by the Leyden University Fund, shows a peculiar group of flowering exotic plants, to which a few mushrooms, a snake, a lizard and some butterflies are added, and on the right side in the back-ground a view on a river or a lake. In the lower right hand corner the painting is signed Lau. Vinn. Prof. Martin concluded from this that it was one of the Haarlem painters Van der Vinne who made it. The most plausible inference seemed to look upon the senior Laurens van der Vinne (1658—1729), a well-known Dutch... |

| As my friend Dr J. Th. Henrard, when young, paid much attention to the adventitious species of Fumaria, I will give here an enumeration of the species found in our country. This genus has been somewhat neglected with us, mainly owing to the fact that the descriptions in our flora’s are not exact, so that the determination was not always easy; the less so as the species are variable in several characters. As I have not much space at my disposal, I will refrain from giving detailed descriptions, but the essential characters I will lay down into the key, so that a correct determination is possible. Minute descriptions are to be found in the splendid works of Mr H. W. Pugsley, which have been a great help to me. |

| In Juli 1931 verscheen het overzicht van de gestrande Nederlandsche Cetacea van 808 tot en met 1930 (Van Deinse, 1931). De toen bekende 211 gevallen van aanspoeling op onze kust werden soort voor soort en een voor een behandeld. Sedert zijn nu weer ettelijke jaren verloopen, waarin jaar na jaar aanteekening werd gehouden van de exemplaren die op onze kust te land kwamen en die zeer nabij die kust of in binnenwateren werden gevangen. Tot en met 31 Dec. 1944, zijn er nu totaal reeds 379 gevallen van stranding bekend geworden en zijn er dus 168 bijgekomen na 1930, alzoo in 14 jaar. Gemiddeld zijn er per jaar 12 dieren gemeld. In de afgeloopen jaren zijn natuurlijk ook aanvullingen en verbeteringen bekend geworden van oudere gevallen en die hoop ik hieronder... |

| Few fossil remains of rodents have been collected in Java until now, and they have received little attention. In the reports published during his paleontological researches in Java, Dubois twice records finds of Hystrix remains, viz., at Pati-Ajam in Japara (Anonymus, 1891, p. 12/13), and in the region between Bangle and Djeroek (Anonymus, 1893, p. 12). In a subsequent paper (Dubois, 1907, p. 454) we find mention of the presence of porcupines in the fossil fauna of Java, but in his review of the latter fauna Dubois (1908) bestows no words upon these rodents. The Selenka Expedition to Trinil secured one tooth, which was figured by Stremme (1911, p. 83, pl. XVI fig. 5) as a right M2 of a small species of Hystrix. Finally a tooth of Hystrix from Sangiran II... |

| Fate has knocked at your door. It has reminded you that, as to the years of your life, you are no longer a young man, that your age will be sixty five on the day this little volume will be presented to you. Time and fate are inexorable powers. Sometimes the question has occurred to me, whether we have any right to speak of a “Jubilee”, whether one’s retirement from office or the attainment of high age is something to be gratulated upon, since these events are usually not exactly welcome to the person involved. Yet, I think there cannot be any doubt as to this. For, can there be ever more reason for deep satisfaction and gratitude than when a man may without self-reproach, look back upon an honest and successful life? |

| In the course of 1944, whilst engaged with the revision of the collections of Hydroids in the Rijksmuseum van Natuurlijke Historie at Leiden and the Zoological Museum at Amsterdam, I had the opportunity to study a considerable number of Hydroids from the tropical and subtropical parts of the three large oceans. No report has up to the present time been published on these Hydroids, although many specimens are of considerable interest. The present paper contains the results of the study of these samples, which were kindly put at my disposal by Prof. Dr. H. Boschma and Prof. Dr. L. F. de Beaufort. I also wish the express my sincere thanks to Mrs. W. S. S. van der Feen née van Benthem Jutting and Miss Dr. Jos. Th. Koster for their assistance in providing me... |

| On October 16th 1946 Dr J. Th. Henrard will have reached the pensionable age of sixty five years. In accordance with the legal prescriptions he is due to take leave officially as keeper of the ”Rijksherbarium“. The present director, Prof. Dr H. J. Lam, invited me to write a short biography of Dr Henrard on this occasion. Having been Henrard’s eldest colleague till 1934 at the institution, I accepted willingly. Jan Theodoor Henrard was born October 16th, 1881 at Maastricht, where his father, J. B. Henrard, was director of the Weight and Measures Office. There is a legend in the family that the Henrards originated from the Vendée (in France) as descendants of a Huguenot-refugee. Owing to this duties J. B. Henrard was often transferred with his family from... |

| When studying the European Caridea of the Rijksmuseum van Natuurlijke Historie at Leiden and of the Zoological Museum at Amsterdam, some specimens of the genus Pandalina came at hand, which proved to belong to a new species. These specimens had already been reported upon by Hoek (1882), who considered them to be Pandalina brevirostris (Rathke). Comparison with typical specimens of Pandalina brevirostris, however, showed various constant differences, which in my opinion justify the separation of Hoek's specimens as a distinct species. In the present paper an enumeration of the specimens of both species of Pandalina present in the above mentioned Musea is given. Pandalina profunda nov. spec. (fig. 1a-c) Pandalus brevirostris Hoek, 1882, Niederl. Arch. Zool.,... |

| According to general opinion the spikelets of Oryza consist, reckoned from their base upwards, of 2 sterile glumes, called hereafter I and II, one fertile glume (valvula inferior; lemma), called hereafter III, and the palea valvula superior) to this glume, called hereafter p3. The spikelets are placed singly on the very short ultimate branchlets, called hereafter pedicels, of a more or less strongly ramose panicle; the tips of the pedicels are broadened into a shallow infra-spicular cup, either distinctly 2-lobed or not; from the bottom of the cup arises a minute knob, on which the very distinct basal callus of the spikelet is jointed. When ripe, the spikelets of the wild species fall off as a whole, disarticulating at the joint (in dried specimens often... |

| Besides the rather scanty material collected before 1900 the Phyllophorinае of the Leiden and the Amsterdam Museums consist of many of Karny's type specimens, and a number of specimens collected in New Guinea, especially by Van Kampen and by Versteeg. Though various authors (Kirby, 1899; Griffini, 1908) published papers of fundamental value concerning this subfamily of the Tettigoniidae, the general survey given by Caudell (1912) was little critical, in different genera even species are placed here of which the synonymy had already been established before (cf. Karny, 1924, pp. 19, 20). A modern revision of the subfamily was given by Karny (1924). Though Karny based his paper on a rather large number of specimens and a great deal of literature, it appears... |

| A taxonomic study of the 6 species of Stipa that inhabit desert regions of the Puna de Atacama S. Bomani Haum., S. venusta Phil., S. obtusa [Nees et Mey.] Hitchc., S. rigidiseta [Pilg.] Hitchc., S. saltensis O. Kuntze, and the new species S. Henrardiana) indicates that they constitute a natural group which I designate Obtusae, using as type the species S. obtusa which is the one with priority. The group is characterised by setose leaves, with ligules 3 to 10 mm long, by glumes that are scarious, smooth, depressed and usually unequal, by the fusiform anthoecium with the palea as long as the lemma and by glabrous anthers. These characters reveal a close relationship with Orthachne Nees and Oryzopsis Michx. More detailed studies are necessary to decide the... |

| Our herpetological collections contain only five specimens referable to the genera Bachia and Scolecosaurus, while the genus Bachia is represented in the Amsterdam Zoological Museum by eight specimens. Scanty though this material may be, some of the specimens proved to be of sufficient interest to justify the publication of these notes. At present thirteen species of Bachia 1) are known, viz., the twelve species listed in a key by Burt & Burt (1931, pp. 315-316) and Bachia anomala Roux (1929, p. 31). Perhaps Apatelus bresslaui Amaral (1935) must be referred to Bachia too. Roux (1929), Burt & Burt (1931) and Loveridge (1933) published notes on the variation of several characters, and these authors showed that the variation is greater than had been... |

| As an introduction to a number of researches of his own the author wishes to give the following data: „Veen” has two meanings in Dutch: 1. in a petrographic sense (peat) Von Büllow’s definition was accepted: „Torf” ist zu deflnieren als ein meist dunkles, kohlenstoffreiches und ± saures Gemenge unvollständig spezifisch-zersetzter Pflanzenteile, das erdgeschichtlich jüngste Glied der Verwantschaftsreihe der Kohlen, dessen Bildung noch heute andauert.” 2. in a plant-sociological-geographic sense (bog) the following definition has been suggested: a bog is a plot, the surface of which consists of a layer of peat, either covered or not with vegetation, with which that layer is genetically connected. The classification of bogs according to their position with... |

It is described in the present paper as a distinct subspecies of Alopoglossus copii Blgr. Peracca (1894, p. 3) showed that in the type of Pantodactylus borellii (= P. schreibersii (Wiegm.)) the tongue is partly covered by imbricate papillae and partly by oblique plicae. He further mentions (1. c., p. 4) that his observation was confirmed by Boulenger who found too that in Pantodactylus schreibersii (Wiegm.) the posterior half of the tongue may be covered with oblique plicae, while the anterior half bears imbricate papillae. Therefore, Burt & Burt (1931, p. 357) unite the genera Alopoglossus Blgr.... |

| In his key to the species of the genus Diploglossus, Boulenger (1885, p. 284) distinguishes between two groups of species, viz., one group in which the digits terminate in "a large compressed sheath, into which the claw may be entirely or nearly entirely retracted", while in the other group such a sheath is absent. Barbour (1910, p. 297) considers the presence or absence of an ungual sheath as a character of generic value ; he separates the species lacking such a sheath from the true Diploglossus, and revives the genus Celestus Gray for them 1). Burt & Burt (1931, pp. 241-242) also stress the importance of this character. Indeed the sheath is absent in Celestes occiduus (Shaw), of which Celestus striatus Gray (the type of the genus) is a synonym. Of... |
