| Recently RIPLEY (1941) has prepared a systematic revision of the Indo-Australian members of the genus Coracina (Cuckoo-Shrike), which for a considerable time had been in a state of great confusion. RYPLEY’s new arrangement represents a noteworthy step in the appreciation of the systematics of this difficult genus. Since only taxonomy and representative distribution have been taken into account by RIPLEY, resulting in the arrangement of 12 species into 3 superspecies and 7 isolated forms, certain problems still remain unsettled. It is the purpose of this paper to deal with some of these problems and to propose an arrangement of the Indo-Australian forms of Coracina not only in accordance with their taxonomy, but also with the history of their distribution.... |

| Since F. Azpeitia Moros, in 1927 (Revista Acad. Cienc. Madrid, Vol. 23, 1927, p. 511—530), published his account of the specimens of Conus gloriamaris in public and private collections and in literature, many new and interesting details on the adventures of various individuals have come to my knowledge. This has led me to make systematic inquiries in the shell collections all over the world and, finally, to compile the following new survey of the representatives of this distinguished species. In spite of many efforts various particulars could not be found out; hence the author is well aware that the revision is not a final one. She hopes, however, that this contribution may serve to draw the attention of systematists and cabinet owners to this idol of... |

| In Juni 1947 werden door mij in enige plasjes in de bosaanplant aan de Z.O.-kant van het eiland, in slootjes tussen de diverse bospercelen en in enige watertjes aan de Westkant (geen eendenkooien!) monsters genomen en wel op de volgende plaatsen: i. Ijsbaan achter het dorp Oostvlieland, 10 VI 2. Plasje in het bos, ten Z. van het schelpenpad langs de Weekend-huisjes, 10 VI 3. Visvijvertje, vlak bij vorig plasje, 10 VI 4- Plasjes bij Vliehors, ten Z. van de grote weg-, li VI 5. Plasje ten Z. van de grote weg iets meer naar Bomenland, 11 VI 6.

| Bindweefsel is de naam van een familie van weefsels, welker gemeenschappelijke afkomst ligt in het mesenchym en welke tezamen gekarakteriseerd zijn door het bezit van meer of minder rijkelijke tussenstof tussen de cellen. Uit didactische overweging zijn we wel gewend de bindweefsels te onderscheiden in enerzijds zulke, welker functie in hoofdzaak bepaald wordt door de tussenstof, anderzijds zulks waarin de cellen de functiedraagsters zijn ¹). Als regel wordt dan vermeld, dat de eerstgenoemde groep (vezelbindweefsel, kraakbeen, been) in het organisme een mechanische taak vervult, terwijl de laatstgenoemde (reticulair bindweefsel, vetweefsel, bloed, weefsels, waarvoor de naam bindweefsel dus eigenlijk niet geldt) aandeel heeft in de stofwisseling. Dat deze... |

| As far as I can recollect, only few reliable informations have been published concerning the total height and weight of new-born giraffe-calves; and as constant measuring of the growth of giraffes probably only in very few cases has been undertaken, I should like, by the following article, to contribute a little to the clearing of these matters. My opservations were made from March, 1939, until December, 1948, on 10 different giraffes whom I had the opportunity of studying at close quarters here in the Zoological Gardens of Copenhagen. On October 24th, 1915, we got a still-born giraffe-calf with a weight of 67,5 kg, the height unfortunately was not recorded. |

| Lower-Villafranchian landmammals lived in the South of the Netherlands when the coastline of the North Sea retired in northern direction during the Plio-Pleistocene transition period. In the province of Zealand their black remains have been fished out of the waters of the Scheldt in the depth of which littoral Poederlian deposits (Amstelian deposits are missing there in Zealand) occur and are eroded by the currents. Also borings in the provinces of Limburg and Guelderland have yielded black fossils of this fauna of which the following species could be stated in the Netherlands: Eucladoceros falconeri (Dawk.), Odobenus huxleyi (Lank.), Alachtherium spec., Anancus arvernensis (Croiz. et Job.), Archidiskodon planifrons (Falc. & Caut.), Gazella schreuderae... |

| In the former Zuiderzee, the large brackish inland sea of the Netherlands, a species of crab was commonly met with, which species generally was considered to be endemic in the Dutch inland waters, and was named by most authors Heteropanope tridentata (Maitland). Examination of material and literature convinced us that the crab does not belong to the genus Heteropanope at all, but is a Rithropanopeus, while it is so closely related to the American Rithropanopeus harrisii (Gould), that we only can consider it to be a subspecies of that species. The synonymy of the Dutch form is as follows: Pilumnus tridentatus Maitland, 1874, Tijdschr. Nederl. dierk. Ver., vol. 1, p. 232. non Pilumnus tridentatus Maitland, 1876, Tijdschr. Nederl. dierk. Ver., vol. 2, p. 11.... |

| Hoewel ik in het voorjaar van 1948 slechts korte tijd op Curaçao en Bonaire verbleef, deed ik hier naast waarnemingen, die een bevestiging zijn van die van RUTTEN (1931), ook een aantal aanvullende observaties. Ik wil deze gaarne publiceren in de feestbundel ter ere van Prof. Dr. J. E. W. IHLE en Prof. Dr. L. F. DE BEAUFORT, met wie ik gedurende vele jaren op verschillend gebied zo aangenaam samengewerkt heb. Over de vogels der Benedenwindse Eilanden is nog slechts weinig geschreven. Eigenlijk bestaat er slechts één goed artikel en wel dat van RUTTEN (1931), die hierin niet alleen oude mededelingen van HARTERT en van CORY verwerkte, maar ook tal van nieuwe, eigen waarnemingen, deels van veldornithologische aard, mededeelde. De lijst van DE JONG (1948) is... |

| In a previous paper (Hoogerwerf and De Boer, 1947, p. 252) we described as Zosterops montana minor a new white-eye from Mt. Papandajan (South Priangan, West Java). Mr. A. C. V. van Bemmel and Dr. Ernst Mayr, however, called our attention to the fact, that the subspecific name minor cannot be used in this case, because this name is preoccupied by Zosterops albiventer minor Meyer. 1874 (p. 105) from Jobi, New Guinea, which is known as Zosterops minor minor in Mayr's (1941) List. On account of the above we have to introduce a new name for Zosterops montana minor. We take this opportunity to add to the original dutch description the following particulars. Siebers (1929, p. 151) separated birds belonging to this species from Central Java (Mt. Sumbing and... |

| If you ask the layman: “What is a museum?”, he will answer. “A museum is a display of objects, that have an aesthetic value or scientific interest; the scope of a museum is to improve the taste of the visitor, is to give him, by visual means, aesthetic or intellectual enjoyment, to satisfy his curiosity, to show him the true and real things (a classic sculpture, an Indian weapon or a deepsea fish) instead of a documentary film, a radio report, or the descriptions and pictures in his books and magazines.” If an architect is in charge of designing a museum, he will see to it that the wallcases and the free-standing objects receive the right light and that the public and the conditioned air can circulate freely. He will design an entrance hall, an exhibition... |

| Wanneer iemand een periode van zijn leven afgesloten ziet, tracht hij voor zichzelf een balans op te maken van de vervlogen jaren. Wanneer hij in die tijd een openbare functie heeft bekleed, zullen ook anderen dat doen. Voor die anderen is dat een moeilijke opgave, want is het schrijven van een necrologie al een moeilijke zaak, het schrijven over een nog levend man van karakter, die het zeker niet zal waarderen in zijn gezicht geprezen te worden, is nog oneindig moeilijker. Toch maak ik dankbaar van de gelegenheid gebruik om de figuur van den scheidenden professor IHLE tenminste voor één maal voor het voetlicht te halen, dat hij altijd zo graag heeft willen ontlopen. Mijn eerste herinnering dateert van begin October 1925, toen de nieuwbenoemde professor,... |

| Some time ago in our laboratory a number of larvae of Caliroa limacina Retz., the well known slug like sawfly larva of the pear, were fixed in toto and sectioned into complete series, which were coloured with EHRLICH’S or HEIDENHAIN’S haematoxylin and counterstained with eosin. Most of these larvae belonged to the last instar but one, i.e., the last instar still feeding and showing the typical mucous covering. The very last instar does not feed any more and lacks the mucous covering, showing the yellow cuticle. As in many other insects, in these larvae the blood cells during fixation agglutinate in a peculiar way. They constitute in the sections compact cell masses imitating a real tissue, but showing, in our preparations, hardly any cell boundaries. Such... |

| As far as I know, little has been published and no thorough investigation has ever been made of the courting, mating, nesting, brooding and rearing of the Condor, though in some of the zoological gardens this largest and in many respects peculiar bird of prey sometimes most succesfully bred. In 1939, 1940 and 1942, a pair of Condors hatched in the gardens of the Royal Zoological Society “Natura Artis Magistra” in Amsterdam. They sat each time on one egg for 58 days alternately. In this way they brought up three young ones, the third of which, however, unfortunately lived only 12 days. It died 9 days after its mother’s death. Besides my preliminary notes in former years, annotations and protocolls were collected in 343 daily reports on this couple and its... |

| Ofschoon een systematisch onderzoek naar het voorkomen en de verspreiding van zoogdieren in de Noordoostpolder niet heeft plaats gevonden, zijn de gegevens daarover, die in de afgelopen jaren bekend zijn geworden, toch wel van voldoende belang om in een publicatie vast te leggen. Over de zoogdierfauna van Urk en Schokland vóór de drooglegging staan ons maar zeer spaarzame opgaven ter beschikking. Schokland werd in 1933 door Utrechtse biologen bezocht en volgens mededeling van de heer M. F. MÖRZER BRUYNS werden toen in de omgeving van Middelbuurt huismuizen en bruine ratten aangetroffen. In 1940 is de heer MÖRZER BRUYNS begonnen met een hernieuwd onderzoek naar de zoogdierbevolking van Schokland en de N. O. polder, maar na het voorjaar 1941 kon hij zich... |

| In the first months of 1941, whilst engaged with the study of Hydroids occurring along the coasts of the Netherlands, I received a small collection of Hydroids from Jersey for identification. These Hydroids, which were kindly sent to me by Mrs. W. S. S. van der Feen née van Benthem Jutting, curator at the Zoölogisch Museum at Amsterdam, had been collected by the late Mr. R. Oppenheim, a very studious amateur-naturalist, during a prolonged stay at Jersey from 1914-1918. Before his death Mr. Oppenheim placed a large number of fine drawings of Hydroids at my disposal, which were made during his stay at Jersey, where he had ample time and opportunities to study an extensive number of living Hydroids. Both drawings and Hydroids are now in the collections of the... |

| 1 specimen, Inhaca Island, Delagoa Bay near Lorenço Marques, coll. Prof. Dr. C. J. van der Horst. This animal closely resembles Ophioteresis elegans Bell, 1892 (Proc. Zool. Soc. London, p. 178, Pl. XI, Fig. 1—5) and Ophiothela tigris (Lyman, 1871, III. Catal. Mus. Comp. Zool. VI, p. 10 in Mem. Mus. Comp. Zool. Harvard Coll. II), both described more in detail by MORTENSEN, 1913 (Mindeskrift for Japetus Steenstrup, X, København). See also SOLLAS, 1914, in Phil. Trans. R. Soc. London, ser. B, vol. 204, Pl. 9, Fig. 2. It differs, however, in having the skin of the upper side of the arms covered by rough thorny nodules, while the smooth grains on the upper side of the disc occur here only between the large radial shields. |

| Im zoologischen Garten zu Amsterdam wurde am sechszehnten April 1939 von einer Hirschkuh der Art Rusa hippelaphus Cuv. ein Junges geworfen, das schon am anderen Tage wieder starb. Da dieses Tier nur einen Tag gelebt hatte, war ein bedeutender Ductus arteriosus Botalli mit ansehnlichem Lumen zu erwarten, wie er auch in Kälbern ziemlich lange nach der Geburt erhalten bleibt. |

| The Isopod and Tanaidacean Crustacea of the Netherlands have not been treated as a whole since 1889, when Hoek published the second part of his Crustacea Neerlandica dealing with the Isopoda and Amphipoda. Hoek in this paper mentioned 25 species of Isopoda, 9 of which are marine forms, 1 a freshwater form and 15 terrestrial, no Dutch Tanaidacea were known to Hoek. At present we know 49 species of Dutch Isopoda, of which 20 are marine, 2 are freshwater forms and 27 are terrestrial, furthermore three species of Tanaidacea are known from this country. The present paper is an enumeration of all Dutch species of the two above mentioned groups, with their distribution within our country and, if necessary, with remarks on their synonymy and ecology. A volume on... |
