    Description: Geological observations, using "free-diving" techniques (Figure I) were made in September, 1960 and March 1961 along two continuous profiles in the outer Kiel Harbor, Germany and at several other spot locations in the Western Baltic Sea. A distinct terrace, cut in Pleistocene glacial till, was found that was covered with varying amounts and types of recent deposits. Hand samples were taken of the sea-floor sediments and grainsize distribution determined for both the sediment as a whole and for its heavy mineral fraction. From the Laboratory and Field observations it was possible to recognize two distinct types of sand; Type I, Sand resulting from transportation over a long period of time and distance and Type 11, Sand resulting from little transportation and found today near to xvhere it was formed. Several criterea related to the agent of movement could be used to classify the nature of the sediment; (1) undisturbed (the sediment Cover of the Pleistocene Terrace is essentially undisturbed), (2) mixed by organisms, (3) transported by water movements (sediment found with ripple marks, etc., and (4) "Scoured" (the movement of individual particles of sediment from around larger boulders causes a slow downward movement or "Creeping" which is due to both the force of gravity and bottom currents. These observations and laboratory studies are discussed concerning their relationship to the formation of residual sediments, the direction of sand transportation, and the intensive erosion on the outer edge of the wave-cut platform found in this part of the Baltic Sea.

    Description: Beschreibung der Geburt von drei Frettchen mit drei Protokollen. In mancher Hinsicht etwa die gleichen Befunde wie MURR (1932). Hier werden nur die abweichenden und neuen Befunde mitgeteilt. 1. Keine Unterschiede zwischen primiparen und pluriparen Tieren. 2. Eine glasige Schleimschnur aus der Vulva ist 2 bis 4 Stunden vor der Austreibung wahrnehmbar. Kurz vor der Geburt steht das Muttertier nur mit gr\xc3\xb6sster Schwierigkeit und liegt oftmals auf dem R\xc3\xbccken. 3. Die Austreibung f\xc3\xa4ngt an mit Pressen. Das Tier nimmt dazu die charakteristische Kothaltung an und geht in die Kotecke. 4. Nachdem die Fruchtblase in der Vulva erschienen ist, wird sie vom Muttertier mit dem Gebiss zerrissen. Nur ausnahmsweise findet ein spontaner Blasensprung statt. 5. Das Junge wird im Liegen weiter ausgetrieben. Die Wehen werden von der Bauchpresse unterst\xc3\xbctzt, wobei die Mutter liegen bleibt. Nur einmal (auf 16 Junge) half die Mutter und zog mit dem Gebiss das Junge auf einmal aus der Vulva. 6. Die Nabelschnur wird von der Mutter mit den Backenz\xc3\xa4hnen durchbissen. Am Bauch des Jungen bleibt ein etwa 2 mm langer Rest \xc3\xbcbrig. Diese L\xc3\xa4nge entspricht genau der Lippendicke des Muttertieres, also der Entfernung ihrer Backenz\xc3\xa4hne vom Nabel des Neugeborenen. 7. Die Nachgeburt wird unmittelbar nach ihrem Erscheinen gefressen, meistens schon bevor man in der Lage ist, diese genau zu beobachten. 8. Auf 16 Junge wurden nur 4 Steisslagen gefunden, also 25%, Kopfendlagen und die Steissendlagen alternierten nicht. 9. In Kopfendlage wird das Junge in Beugehaltung geboren (Kopf liegt der Brust an), aber in Steissendlage ist das Junge gestreckt. 10. Der Mittelwert der Austreibezeit pro Frucht ist in Kopfendlage 3,5 Minuten, oder wenn man von dem erstgeborenen Jungen absieht, 2,6 Minuten, und in Steissendlage nur 43 Sekunden. 11. Zwischen den Geburten von 2 Jungen liegen Zeitabschnitte von 3 bis 74 Minuten. 12. Der Nabelschnurrest am Bauch des Jungen f\xc3\xa4llt ab nach 4 bis 5 Tagen.

    Description: Entamoeba invadens RODHAIN is known as a dangerous parasite in reptiles, especially snakes and lizards. Up till now it has mostly been found in specimens which are kept in captivity. When these are carriers they show no signs of disease, but the faeces contain cysts and can infect healthy reptiles. If the reptiles are ill, the symptoms mostly are serious. They begin with a loss of appetite and an increasing need for drinking water. Within a few weeks the faeces merely consist of bloody mucus, containing a large number of hystolytic forms as well as a few cysts of Entamoeba invadens. In the case of Lacerta agilis (STAM, 1958), the animals died on an average within 25 days from inoculation (14 to 34 days). Different species of Natrix which had been infected died in 13 to 77 days from the onset of infection (RATCLIFFE and GEIMAN, 1938). BARROW and STOCKTON (1960) found that the temperature affected the symptoms in infected snakes. When the animals were kept at 13\xc2\xb0 C there were no internal pathological changes within two to six weeks but at 25\xc2\xb0 C these were very clear.\nThese changes, as described by different authors, are ulcers of the colon. In experiments nearly the entire colon is damaged to such an extent that no individual ulcers can be distinguished. Ulcers may also be found in the ilium. The liver may have one or several abscesses. Inflammation sometimes spreads from the gut to the kidneys.

    Description: La naissance de jeunes phoques a lieu dans nos r\xc3\xa9gions, en g\xc3\xa9n\xc3\xa9ral au cours des mois de juin\xe2\x80\x94juillet. C\xe2\x80\x99est alors qu\xe2\x80\x99apr\xc3\xa8s une gestation d\xe2\x80\x99environ 11 mois, le jeune vient au jour, mesurant 80\xe2\x80\x9485 cm de longueur et pesant de 12 \xc3\xa0 20 kg; il est la plupart du temps d\xc3\xa9j\xc3\xa0 recouvert du deuxi\xc3\xa8me pelage brillant aux reflets argent\xc3\xa9s. Le pelage embryonal du d\xc3\xa9but (lanugo) est de fa\xc3\xa7on g\xc3\xa9n\xc3\xa9rale rejet\xc3\xa9 avant la naissance, mais parfois aussi pendant le processus de la mise bas; on le trouve alors sur la c\xc3\xb4te avec l\xe2\x80\x99arri\xc3\xa8re-faix. La m\xc3\xa8re nourrit son rejeton (pup) \xc3\xa0 terre, jusqu\xe2\x80\x99\xc3\xa0 ce qu\xe2\x80\x99il soit devenu dodu (\xc2\xb1 4 semaines), apr\xc3\xa8s quoi il est abondonn\xc3\xa9 \xc3\xa0 lui-m\xc3\xaame (1). Apr\xc3\xa8s quelques jours ou quelques semaines de difficult\xc3\xa9s, le jeune a finalement appris \xc3\xa0 s\xe2\x80\x99alimenter et se d\xc3\xa9veloppe en \xe2\x80\x9eyearling\xe2\x80\x9d. Jusqu\xe2\x80\x99ici tout est normal et naturel.\nMais il arrive de temps en temps que naissent des jumeaux. Comme chez les phoques c\xe2\x80\x99est la m\xc3\xa8re qui suit le jeune et non le jeune qui suit la m\xc3\xa8re, il en r\xc3\xa9sulte r\xc3\xa9guli\xc3\xa8rement qu\xe2\x80\x99un des jumeaux reste en arri\xc3\xa8re sans assistance maternelle. Vu que la m\xc3\xa8re suit le jeune qui peut-\xc3\xaatre criait le plus fort ou que pour telle ou telle raison elle pr\xc3\xa9f\xc3\xa9ra, il se fait que le deuxi\xc3\xa8me jeune reste sans aide et affam\xc3\xa9, appelant instinctivement l\xe2\x80\x99aide maternelle jusqu\xe2\x80\x99\xc3\xa0 ce qu\xe2\x80\x99il meure d\xe2\x80\x99\xc3\xa9puisement; le nom de \xe2\x80\x9eHeuler-huiler\xe2\x80\x9d (criard) utilis\xc3\xa9 internationalement pour d\xc3\xa9signer le jeune abandonn\xc3\xa9, est donc bien choisi.

    Description: Frederik Johannes Appelman werd op 18 juli 1894 te \xe2\x80\x99s-Gravenhage geboren. Reeds als jongen had hij belangstelling voor alles wat dier was, doch speciaal voor vogels. Met jeugdig enthousiasme bracht hij o.a. een eiercollectie bij elkaar. Toen hij zich, ter verrijking van zijn verzameling, echter eens vergreep aan een legsel zwaneneieren in de Haagse hertenkamp, maakte een geduchte vaderlijke schrobbering aan deze activiteiten een hardhandig einde. Mogelijk heeft dit jeugdtrauma er toe bijgedragen dat hij op latere leeftijd voor de museale zo\xc3\xb6logie een ietwat platonische liefde heeft gekoesterd. Frits Appelman werd geen bioloog, omdat hij meende dan uitsluitend tot het onderwijs beperkt te zullen blijven en zijn hart trok naar buiten. Het studievak van zijn keuze werd Tropische Bosbouw. Als Bosbouwkundig ingenieur vertrok hij in 1919 naar het toenmalig Nederlands Indi\xc3\xab, waar hij als houtvester werd geplaatst bij de Dienst van het Boswezen. Die functie vervulde hij op verschillende standplaatsen. Door herhaalde overplaatsingen kwam hij met vrijwel geheel Insulinde in kennis en met zijn intense belangstelling voor tropische natuur werd ieder contact met een nieuw landschap tot een blijvende ervaring. Inmiddels doorliep hij vlot zijn rangen. Hij werd in 1928 bevorderd tot Opperhoutvester en in 1940 tot Inspecteur bij de Dienst van het Boswezen voor de Inspectie Grote Oost. Dat betekende een ressort van de afmetingen van West Europa en een gelegenheid om nader kennis te maken met de biologische aspecten van het merkwaardige Indo-Australische overgangsgebied. Na de Japanse inval in 1941 kwam Ir. Appelman als krijgsgevangen reserveofficier in een interneringskamp terecht. Bij de bevrijding aanvaardde hij zo spoedig mogelijk zijn oude functie. In 1947 werd hij gepensioneerd en repatrieerde. Daarmede was zijn Indische carri\xc3\xa8re op normale wijze be\xc3\xabindigd.\nReeds tijdens zijn langdurige diensttijd bij het Boswezen was Ir. Appelman zeer actief werkzaam op het gebied van Wildlife-management. Als beheerder van natuurreservaten en gouvernementsbossen ontwierp hij systemen voor wild-tellingen en paste die ook in de practijk toe. Hij publiceerde talrijke artikelen in \xe2\x80\x9eDe Tropische Natuur\xe2\x80\x9d, \xe2\x80\x9eTectona\xe2\x80\x9d (o.m. J. F. Kools en F. J. Appelman; Inventarisatie van den Wildstand. Tectona III, afl. 7/8, juli/aug. 1949) en vroegere Ned. Ind. couranten, meestal over de grote wilde diersoorten. Verder verscheidene bijdragen in Der Zoologischen Garten, Mededelingen der Ned. Commissie voor Internationale Natuurbescherming en het Avicultural Magazin. Het ontwerp van de Nieuwe Jachtwet voor Nederlands Indi\xc3\xab kwam van zijn hand. Zijn grote verdiensten op dit gebied vonden erkenning in zijn benoeming tot Officier in de Orde van Oranje Nassau.

    Description: From its origin, the right aortic arch passes anteriorly, and obliquely to the right; in this part of its course it gives off the two carotid arteries, or as the case may be (e.g., in Uropeltis melanogaster (GRAY)) the common carotid trunk. It then curves dorsally, medially, and caudally. At the end of the dorsal curve, the right aortic arch gives off the vertebral artery, which runs cranially, close to the ventral surface of the vertebral column, to enter the parietes at a greater or smaller distance behind the head. In its further course, the right aortic arch fuses with the left aortic arch to form the dorsal aorta, which passes caudally close to the ventral surface of the vertebral column. The intercostal arteries arise from the vertebral artery, from the right aortic arch (between the origin of the vertebral artery and the fusion of the two aortic arches), and from the dorsal aorta. These intercostal arteries pass dorsally, and they enter the parietes in varying ways, as has been described by BEDDARD (1903; 1904a, b; 1906a, b; 1908; 1909) in a series of papers on the anatomy of snakes. This author has pointed to the possible taxonomic value of the differences shown by the various genera and species, which he examined. However, before definite conclusions can be drawn, it will be necessary to examine more genera and species. Studying the intercostal arteries of snakes is time-consuming; their number may be very high (e.g., 156 in a specimen of Xenopeltis unicolor Reinw.), and every artery has to be checked, because various types of intercostal arteries may occur in one individual.\nThe following types of intercostal arteries can be distinguished.

    Description: The presence of five specimens of Gough Island Gallinules, Porphyriornis nesiotis comeri ALLEN, in the Zoological Gardens of Amsterdam originating from the remote Gough Island situated within the subantarctic confines of the South Atlantic Ocean, offered a favourable occasion for a study of these peculiar and rare birds. The Gough Island Gallinule is presently the only surviving representative of its species; the Tristan da Cunha form, P. nesiotis nesiotis (P. L. SCLATER), having been exterminated by man probably nearly a century ago. It belongs to a group of rails of which also the Moorhen or Common Gallinule, Gallinula chloropus, is a representative. From the latter species it differs among others by having greatly reduced powers of flight. One can wonder, however, about the degree of relationship between members of the genus Gallinula on the one hand and the Gough Island Gallinule on the other hand. In fact, the general appearance of the Gough Island Gallinule is that of a very stout, strongly legged Common Gallinule with a more skulking, less graceful gait. The birds in captivity in the Amsterdam Zoo were very pugnacious, a habit which has also been recorded by previous authors. When in pursuit of each other the birds frequently uttered a sharp, rattling call, which was also described by HOLDGATE (1958) from birds observed in Gough Island and transliterated as a rapid \xe2\x80\x9cchack-chack\xe2\x80\x9d. It seems that this call has not been recorded from any member of Gallinula chloropus. In spite of these differences RIPLEY (1954), in reviewing the \xe2\x80\x9cgenera\xe2\x80\x9d Gallinula, Porphyriornis and Ionornis, has doubted the justification of the use of a separate genus name for the Flightless Gallinules from Tristan and Gough Island, which he would prefer to treat as members of the genus Gallinula. This question will again be considered here.

    Description: Since the time of the great geographical discoveries, since Henry the Navigator of Portugal and Christopher Columbus started to open up the whole world to the curiosity of naturalists, the Dutch and the English have played an important role in the explorations of the riches of God\xe2\x80\x99s Nature.\nThe Monarchs were the first to set up collections of animals and other natural curiosities from foreign tropical (and also arctic) countries and from everywhere. We need only remember Albrecht D\xc3\xbcrer\xe2\x80\x99s diary from 1520\xe2\x80\x941521, when he visited the Low Countries.

    Description: A male skull of Tapirus terrestris (L.) originating from Dutch Guiana (Leiden Museum, reg. no. 11632), received from the Rotterdam Zoological Garden through the kind intermediary of Mr. F. J. APPELMAN on July 15, 1952, is remarkable for the abnormal development of its right P1. The full permanent dentition is in place except for the posterior premolars and last molars, which are in alveolo. The teeth are but little worn and, apart from the right P1, they do not show anv unusual characters.\nThe left P1 has the shape normally found in the Brazilian tapir; the crown is triangular with rounded angles, and bears a continuous outer crest (ectoloph) extending from the front angle (parastyle) to the posterior outer cusp (metacone). The position of the central outer cusp (paracone), merged in the crest, is indicated only by a weak vertical ridge on the labial face of the ectoloph, flattening toward the crown base, the paracone style. The posterior inner cusp (hypocone) is a low but distinct, anteroposteriorly elongated elevation of the cingulum. The protocone is just visible as a tiny cusp on the lingual cingulum, internal to the paracone. The labial cingulum is shown as a slight swelling all along the base of the ectoloph. There is a broad posterior root, imperfectly subdivided into a larger labial and a smaller lingual portion, and there is a single anterior root; the roots are but slightly divergent. The anteroposterior diameter of the crown is 17.1 mm, the posterior width, 13.2 mm.

    Description: Wie fast jeder Zoologische Garten in Europa h\xc3\xa4lt auch der Basler Tiergarten eine Flamingo-Schar. Als erster bunter Gruss steht diese pr\xc3\xa4chtige Vogelgruppe gleich beim Eingang und jeder Besucher bleibt staunend vor diesen grotesken V\xc3\xb6geln stehen. Bis vor kurzem erfolgte aber, wie in allen andern G\xc3\xa4rten, niemals eine Brut. Und da der heutige Tierg\xc3\xa4rtner das Gef\xc3\xbchl hat, seine Tiere m\xc3\xbcssten sich fortpflanzen, wenn sie sich wirklich im Zoo wohlf\xc3\xbchlen, haben wir seit einigen Jahren unser besonderes Augenmerk auf unsere Flamingos geworfen. Diese V\xc3\xb6gel leben auf einer Wiese mit einem Weiher und einem Bambusgeh\xc3\xb6lz. Gegen das Publikum sind sie nur durch Steinreihen abgegrenzt und sobald die Besucher den Garten verlassen, betreten die Flamingos auch den vor ihrer Anlage liegenden Asphaltplatz. Besonders im Fr\xc3\xbchjahr und im Herbst, wenn vermutlich eine gewisse Zug-Unruhe eintritt, machen sie hier und da kleine Ausfl\xc3\xbcge auf den nahen Wegen.\nDie Gruppe besteht aus etwa 35 Rosenroten Flamingos (Phoenicopterus ruber roseus), etwa 10 Chilenischen Flamingos (Phoenicopterus ruber chilensis) und 9 Kubanischen Flamingos (Phoenicopterus ruber ruber). Seit dem Juli 1959 leben auch einige Zwergflamingos (Phoeniconaias minor) bei der Gruppe.
