| Die vorliegende Arbeit stellt ein ausführliches Resumé einer Arbeit in holländischer Sprache dar: „De geologie van het westelijk deel van het Heuvelland van Monferrato tusschen Turijn en Murisengo”, Dissert. Leiden, Augustus 1941 2). Das bearbeitete Gebiet ist bisher, namentlich in tektonischer Hinsicht, nur oberflächlich untersucht worden. Störungen wurden nie erwähnt, Profile waren nur spärlich vorhanden. Da sich die Stratigraphie als ausserordentlich interessant erwies, sobald die feineren Merkmale in einer Karte eingetragen wurden, wie es hier geschah 3), konnte zum ersten Mal ein Schema der sedimentären Genese für einen erheblichen Teil der Berge von Monferrato aufgestellt werden. |

| In 1938, Verdam published an account of the then-known Charophyta of the Netherlands in the English language (cf. this journal, vol. 3), and one year later (1939) another in our own language in “Nederlandsch Kruidkundig Archief”. In both papers reference was made to only five Netherlands’ publications on the same subject, the oldest of which is dating from 1846. In studying i.a. the history of the Malaysian Charophyta (Zaneveld, 1940) I found that much more was published on the Charophyta of our Low Countries. As will be seen below, it became evident that the first printed record of a Netherlands’ Charophyte dates as far back as 1636. It seems worth while to publish these notes on the history of the identification of our Charophyta as, moreover, a number... |

| In my first paper on Malaysian Convolvulaceae in Blumea III, 1938, p. 62—94, I pointed out (p. 83) that Neuropeltis racemosa Wall, has often been confounded both in literature and in herbaria with another species from the Malay Peninsula, N. Maingayi Peter. Moreover, on p. 85, I expressed my doubt whether specimens from Indo China, mentioned in literature as N. racemosa Wall, (by Gagnepain & Courchet in Lecomte, Flore Generale de l’Indo-Chine IV, 1915, p. 290, fig. 31) actually belong to that species. A more detailed study of materials from Indo China has now brought to light, that the plants from that country are different from those occurring in the Malay Peninsula and that they represent a new, though closely related, species. Specimens from the... |

| Among the Acanthaceae grown in the glasshouses of the University Botanic Garden, Utrecht, a plant labelled Aphelandra velutina drew my attention, first, because it obviously belonged to an entirely different genus, and secondly, because a description under this name could nowhere be found. The coincidence of these two grounds for bewilderment might be explained by assuming that Aphelandra was merely a perversion, probably caused by the inadvertency of a transcriber, of the true generic name. This sounded plausible enough, but the name itself could not be found, for all attempts to refer the plant to one of the existing genera failed. It looked as if the plant might have been described somewhere, but for the time being there was no indication at all as to... |

| When rearranging a part of the collections of Orthoptera in the Rijksmuseum van Natuurlijke Historie at Leiden I found a number of specimens belonging to this tribus, which by former authors is considered as a separate subfamily with the name Eumegalodontinae (Kirby, 1906, p. 289; Caudell, 1927, p. 30). With Karny I think it justified to let it retain its place as a tribe of the Copiphorinae. The representatives of this group are of such a remarkable shape that they can easily be recognized among the other Copiphorinae by their relatively big head and strangely shaped prothorax, which bears strongly spined lateral processes on the disc. The species under consideration can be divided into two groups, in the one of these the specimens possess a number of... |

| Bekanntlich hat K. Martin zweimal (1933, 1935, vgl. auch 1937) einige Mollusken aus dem angeblichen Oberoligocän der Insel Buton beschrieben, auf deren merkwürdige Charaktere er ausdrücklich hinwies. Ich selbst konnte seine Feststellungen an Hand reichlichen neueren Materials nur bestätigen und ergänzen 1): wenn man, es sei an dieser Stelle wiederholt, diese Molluskenfauna auf ihren Zusammenhang mit anderen Faunen hin prüft, so kommt man bald zu der Einsicht, dass zu anderen palaeogenen Faunen fast gar keine Beziehungen bestehen, jedenfalls nicht zu jenen benachbarter Erdteile (diese Verwandtschaftsbeziehungen sind vielleicht bloss Konvergenz-Beispiele); wirklich nahe Beziehungen bestehen nur zu der Neogenfauna nahegelegener Teile des ostindischen... |

| Smith (1937, pp. 215—216, fig. 1) described and figured the different types of scales of the lower surface of the toes in Lygosoma and allied genera. Although several of these types may be found within one genus, they are useful as additional characters to distinguish certain species or groups of species from each other. When studying a number of IndoAustralian scincid lizards, I noticed that the arrangement of the scales on the dorsal surface of the digits shows differences too, which it may be worth while to include in the descriptions of the species as they provide additional characters. The arrangement of the scales seems to be fairly constant within the species. In some cases slight variations were found, but in a series of over one hundred specimens... |

| Lygosoma (Sphenomorphus) florense barbouri Dunn (Pl. VI fig. 1) Sphenomorphus florense barbouri Dunn, Amer. Mus. Nov., no. 288, 1927, p. 5, and Dunn, in: Burden, Dragon Lizards of Komodo, 1927, p. 203. 1 ♂, Noil Toko, Timor, 1937, leg. P. F. van West, Mus. Leiden, reg. no. 7033. 5 ♂ ♂, 6 ♀ ♀, Timor, leg. Müller & Macklot, Mus. Leiden, reg. no. 2535. 3 ♂ ♂, 7 ♀♀,2??, Samao, leg. Müller & Macklot, Mus. Leiden, reg. no. 2534. These specimens are provisionally referred to the subspecies barbouri, described by Dunn from Wetar .Id. The dark colour of the throat apparently is a character dependent on age; with four exceptions all specimens of a head and body length above 51 mm have black throats or at least some black spots on the throat. Of the four... |

| In a tube (no 282) containing several specimens of algae collected by Dr R. E. Vaughan, Curepipe, Mauritius, in quiet lagoons at Black River Bay a few specimens of a small delicate Griffithsia occurred as an epiphyte upon Laurencia papillosa (Forssk.) Grev. Since this plant has turned out to be a not previously described species it is a great pleasure to me on the occasion of Mme Dr A. Weber—van Bosse’s 90th birthday to name it in honour of her in the hope that Mme Weber will take it not only as a proof of my gratitude for a friendship extending over many years, but also as a token of my admiration for the important contribution made by Mme Weber to our knowledge of the tropical marine algal flora, especially by her great classic work ”Liste des Algues du... |

| En examinant en 1939 dans une note présentée à l’Académie des Sciences de Belgique une étude de M. Ronse, nous avons été amené à reprendre des considérations sur les mucilages des végétaux et en particulier sur ceux des algues (22; 31). Déjà en 1891, dans nos ”Observations algologiques“ nous avons examiné la nature et la structure des parois cellulaires de certaines algues et fait remarquer que la gaine mucilagineuse de Conjuguées, étudiée par divers auteurs était loin de présenter sur toute la surface d’un filament la même épaisseur. Des Spirogyra, par exemple, suivant des parties du filament, montraient une gaine nette et épaisse, ou à peine indiquée. |

| Part I of this monograph has been published in volume 10 of this Journal, pp. 241—320, 1938. Preparing this second part I met with the help and assistance from many persons and institutes again, for which I express my most cordial thanks here. The figures illustrating this paper have been drawn once more by Mr. L. P. Pouderoyen, while the „Zoologisch Insulinde Fonds” supplied the cost of these illustrations. |

| Het onderzochte gebied ligt in het westelijk gedeelte der Noord-Apennijnen, die zich van de omstreken van Genua in het W tot de Monte Falterona in Toscane in het E uitstrekken. De naam van Ligurische Apennijnen, die vooral door niet-Italianen aan dit gebergte wordt gegeven, is minder verkieselijk, aangezien tot de Ligurische Apennijnen vaak ook het gebergte ten W van Genua wordt gerekend, dat volgens Stille, Kober, e. a. reeds tot de Alpen behoort, volgens Staub e.a. daarentegen een overgangszone vertegenwoordigt tusschen Alpen en Apennijnen, maar dat in ieder geval in bouw zoo sterk afwijkt van de overige Apennijnenketen, dat het juister is de westgrens der Apennijnen ten N van Genua te trekken (fig. 1). Zooals in de titel aangegeven, worden west- en... |

| 1) Examining the Semper-collection of mollusca from the Philippines kept in the Leyden Geological Museum, I met with some generic undetermined specimens of a representative of the genus Atopodonta (from Tertiary strata only rarely recorded), all belonging to one and the same species, which appeared never to have been described before. This genus 1) is known from the Eocene of the Paris basin represented by two species, viz. the typespecies Atopodonta conformis (Deshayes), 1860 [Deshayes,. Anim. s. vert., I, p. 419, plate 28, fig. 14—16 (“Venus”); Cossmann, Catal. ill., I, 1886, p. (98— 100) 99, plate 6, fig. 3—6 (excl. plate 8, fig. 3—4)] and A. tapina Cossmann, 1886 (l.c., p. 100, plate 6, fig. 7—9). These are the only European species. In 1941 I was in a... |

| Though an excellent, critical monograph of the genus Cassipourea was published some years ago by ALSTON (in Kew Bulletin, 1925, p. 241—276), I should like to make a few remarks on the South-American species of this genus as my revision for PULLE’s Flora of Suriname III.2 has brought to light a few new facts. It will also give me an opportunity to refer to a publication of BRIQUET on some American representatives of this genus (in Candollea IV, 1931, p. 342—350), which disagrees with regard to a number of species with ALSTON’s interpretations. The species which covers the largest area is the chiefly West-Indian C. elliptica (Sw.) Poir. Formerly also a number of West- Brazilian and Peruvian specimens were referred to it, but ALSTON pointed out that these... |

| Anne Antoinette van Bosse, fille de M. Jacob van Bosse et de Mme Jaqueline Jeanne née Reynvaan, naquit à Amsterdam le 27 mars 1852. Très jeune encore elle perdit sa mère; sa soeur, son ainée de 10 ans, prit sa place aussi bien qu’elle put. Outre cette soeur elle avait trois frères. Selon l’usage de cette époque les familles aisées n’envoyaient pas leurs filles à l’école, ainsi Anna van Bosse reçut à la maison son instruction par une institutrice de nationalité suisse. La botanique et la zoologie furent d’emblée ses branches préférées; les fréquentes visites au jardin zoologique ”Artis“ y contribuèrent pour une grande part. l’Observation des animaux exotiques lui procurait un grand plaisir et jusqu’à présent elle porte un grand intêret à ”Artis“. |

| Crystals of the notched or grooved type are known from some minerals which crystallise in the cubic system. From diamond grooved octahedrons are known, whose grooves remind us of octahedral faces, or the faces of triakis octahedra or hexakis ostahedra. From haüynite too grooved octahedrons are pictured, whose grooves are bordered by octahedral faces. Grooved analcite is known in icositetrahedrons, the grooves are bordered by faces of the same icositetrahedron. |

| Roon, J.M. van. |
| In 1939 J. M. van Roon and J. J. ter Pelkwijk published some data on two specimens of Orthragoriscus mola (L.) stranded on the Dutch coast. Measurements of bones and muscles of the jaw were given on account of the functional treatise concerning the mechanism of the jaw of Orthragoriscus given by Van Dobben (1935), based upon one specimen that differed in many ways from both individuals we dissected. In the following years, we got three more specimens and an examination of the jaw muscles proved them to be fully agreeing with the two fishes described before. It seems worth while to publish corresponding data and measurements. Specimen C, a female, stranded December 12, 1939 near Kamperduin in the neighbourhood of Schoorl. This fish was more oblong than... |
