Under the above title I intend to publish a number of short notes on Cerambycidae, including synonymies, descriptions of new species, etc. For the greater part the material on which these notes are based is from the Rijksmuseum van Natuurlijke Historie at Leiden. In other cases the collections are always indicated. Each set of notes published together will be arranged according to Aurivillius in Coleopterorum Catalogus (JunkSchenkling), parts 52, 39, 73 and 74. I. ADDITIONAL NOTE ON RHAPHIPODUS DRESCHERI DE JONG (PRIONINAE, PRIONINI) Rhaphipodus drescheri De Jong (fig. 1a and b) Rhaphipodus drescheri De Jong, 1936, Zool. Med., vol. 19, p. 77. When studying some Cerambycidae in the collections of the Amsterdam Zoological Museum I found three specimens, 2 ♀♀... |

Meeuse, A.D.J.. |
On preparing the manuscript of the Verbenaceae for Dr C. A. Backer’s ”Flora van Java” it appeared to me that — in comparison with the monographic treatments of this family by Lam (5) and by Lam & Bakhuizen van den Brink (6) — several changes in the nomenclature and in the interpretation or delimitation of certain species are urgent. Although, considered in the light of more recent work on this family as it occurs in adjacent regions (2, 3, 8), a new critical revision of the Malaysian Verbenaceae seems desirable, we have to refrain from such a task, which would require a greater deal of investigation than the present author is able to afford at the time. Hence these notes are merely intended to account for the discrepancies between the treatment of the... |

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... |

Amshoff, G.J.H.. |
In trying to prepare the account of the Myrtaceae for PULLE’s Flora of Suriname I soon found that a revision of the Myrtaceae of whole Guiana, especially of French Guiana, and preferably also of the Amazonian district, is necessary. The account would be of little value as long as our knowledge of the synonymy and the distribution of the species is so incomplete. The Myrtaceae of Guiana have been treated by BERG in Linnaea XXVII (1855—56) p. 1—512, XXIX (1858) p. 207—256 and XXX (1861) p. 647—713. Yet many species previously described from French Guiana, especially by AUBLET and by DE CANDOLLE, were not known to BERG. Moreover, BERG often based species on insufficient material, as has been pointed out by URBAN in his revision of the West Indian Myrtaceae in... |

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“. |

1. Es sind bisher über die merkwürdige rezente marine Gastropoden-Gruppe Thatcheria Angas, 1877 sehr wenige Gegebenheiten bekannt, vergleichende Untersuchungen mit fossilen Arten fehlen (fast) vollkommen und auch die Frage ihrer systematischen Stellung ist nie in befriedigender Weise gelöst worden. Auf Grund vergleichender Forschungen bei der Bestimmung gewisser fossiler, systematisch schwieriger, doch morphologisch einfacher ostindischer Arten glaube ich diese Frage endlich — jedenfalls zum grössten Teil — lösen zu können, dank auch der von N.B. Eales ausgeführten anatomischen Untersuchung der einzigen lebenden Art dieser „Gattung”. Angas beschrieb 1877 eine Schale der hiesigen Art, Thatcheria mirabilis von Japan; er betrachtete sie vorläufig als Glied... |

Pulle, A.. |
In my revision of the Turneraceae for PULLE’s Flora of Suriname, I have accepted the genera Piriqueta and Turnera in the delimitation given to them by URBAN. The distinction rests on the presence in Piriqueta of a “corona” at the insertion of the petals. This corona, however, is often so weakly developed as to be almost invisible, and as moreover, the African representatives of Piriqueta appear to be more easily distinguishable from the American ones than the latter from some of the Turneras, the taxonomic importance of this organ appears to be somewhat dubious. A decision of the question, however, would necessitate a more extensive study of the genera than the demands of the present revision would justify; owing to lack of material, moreover, such a study... |

The ovule of C. arabica L. consists õf a single integument and a small nucellús which disappears as the ovule matures. Three of the four macrospores resulting from the'division of the macrosporocyte, degenerate. The remaining chalazal cell gives rise to a "normal'' embryo sac, which is ready for fertilization at the time of the flower opening. Double fertilization occurs, as a rule, the day the flower opens. The embryo sac then increases in volume and compresses the inner integument cells. The outer cells of the integument, however, multiply actively, giving rise to the "perisperm". After degeneration of the synergids and antipodals, the zygote stays near the micro-pyle in a resting stage, while the primary endosperm nucleus divides. This first division of... |

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. |

Boeke, J.E.. |
An attempt has been made to subdivide a very polymorphous plant species by means of a quantitative statistical method. This method has been based upon the following working hypothesis: 1° as some morphological characters of the material, concerning e. g. the shape of the leaves, the length of the pedicels etc., show an extremely great variation, each of these characters in every specimen at hand may be stated to be in one of three (one intermediate and two extreme) conditions; 2° if a character happens to be in an intermediate condition in a relatively great number of specimens the difference between the extreme conditions of that character may be considered insignificant from a taxonomical point of view; 3° the fewer characters of two or more specimens... |

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... |

Ooststroom, S.J. van. |
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... |

The genus Galaxaura can in several respects be classed among the most remarkable Florideae. It is not only — with Chantransia — the genus richest in forms of all the genera belonging to the order of Nemalionales, which has more than 70 described species, it also offers, both in its interior and its exterior organization, such a high differentiation, and a tissue specialization going so far, that, as the monographer of the genus, the late Professor F.R. Kjellman (1900), said: ”it may be difficult even in the great province of the Florideae to find forms with a higher or even as high a division of labour in the tissues of the shoot...“. Even if the number of species may actually diminish with further investigations, this is in a way connected with a... |

Meeuse, A.D.J.; Vervoort, W.. |
During a visit to southern Limburg in the summer of 1942 several living specimens of Helicigona lapicida (L.) were discovered near Kamerig. In this locality the species was found in such large numbers that it seems almost astonishing that its occurrence in such abundance there had hitherto escaped attention. So far the occurrence of undoubtedly living specimens of this characteristic snail in the Netherlands has only been reported by Vervoort (1941), who recorded specimens from a couple of localities also situated in southern Limburg, where, however, the species had only been found in small numbers. Henrard and Koumans (1936) had previously drawn the attention to the occurrence of more or less fossilized specimens in various localities in the same region.... |

In the following pages data will be given about the size of the megalospheric embryonic apparatus, and of the size of the shell, of some Foraminifera. By comparing these data for a certain species from different samples, the relative ages of which are known, it will be possible, to get an insight into the alterations of the measured characters in geological times. For that purpose samples from geological sections, or otherwise well defined geological formations, were used. A description of each of these sections will be given, in order to discuss the reliability of the determinations of the relative ages of the samples. I may point out here, that as the layers containing the foraminiferal shells have a certain thickness, and as the sampling has been done... |

While studying the literature on recent and fossil Hippopotami it became evident to me that a number of authors ascribe a third milk incisor to Hippopotamus amphibius L. Consequently this species, as regards the milk dentition, should be "hexaprotodont" like the Pliocene and Pleistocene species of Hippopotamus from the Siwaliks of India, Burma and Java; and like H. pantanellii Joleaud (1920, p. 18) from Casino near Siena in Italy (vide Pantanelli, 1879, p. 318, pl. IV fig. 5). According to Major (1896, p. 978) young specimens of H. lemerlei Grandidier from Madagascar occasionally are hexaprotodont too. When dealing with Hippopotamus amphibius L. Blainville (1847, p. 32) made the following remarks: "Dans le très-jeune âge, il est certain qu'il y a trois... |

Varossieau, W.W.. |
Summarizing, it appears that Eucommia has the greatest number of characters in common with the Urticales. This is shown by the similarity of the inflorescences as well as by the unisexual flowers and the dioecy. In both groups the pistil consists of 2 connate carpels and the ovary is usually 1-celled by abortion, while the stigmata are generally papillate. Further general points of relation with the Urticales are the originally spiral phyllotaxis, which becomes later on pseudo-distichous, simple vessel perforations, libriform with bordered pits, unicellular hairs and the occurrence of calciumcarbonate and silica as well as of latex elements. Yet, it seems difficult to indicate any particular family in the Urticales to which Eucommia should be most related.... |

In recent literature two subspecies of Mustela nudipes, viz., Mustela nudipes nudipes Desm. and Mustela nudipes leucocephalus (Gray), are recognized. In a survey of the Indo-Australian weasels, Dammerman (1940, p. 269) discussed the possibility of recognizing these two subspecies, but through lack of material he could not arrive at a definite conclusion. Since Dammerman's notes were published three more specimens were brought to light in the collections of our Museum. Moreover we had at our disposal two specimens from the collection of Mr. H. J. V. Sody, as well as four specimens and a skull in the Amsterdam Zoological Museum. A study of the variation of Mustela nudipes led us to reconsider the status of Mustela hamakeri Dammerman (1940, p. 266, pl. XV) as... |
