SCAMANDRA UNDULATA n.sp. ♂, Ocre brunâtre plus ou moins foncé suivant les exemplaires; pattes brun noirâtre. Face supérieure de l'abdomen plus ou moins rouge, avec au milieu une grande tache un peu plus foncée. Les deux tiers antérieurs des élytres sont havane, avec d'assez nombreuses petites taches d'un rouge foncé et de très fins points noirs surtout visibles le long des grosses nervures; entre cette partie et la postérieure, une bande rouge pâle, transversale, ondulée, présentant au milieu de la largeur une large convexité vers l'avant; la partie postérieure est un peu plus claire que l'antérieure; à la face supérieure se voit une bande rosée, parallèle au bord apical; à l'inférieure cette bande est blanche, les nervures sont jaunes ou ocre, sur... |

The peculiar distribution of the species of Rhizophora (Rhizophoraceae) is wellknown. Floras and manuals usually mention one western species — R. mangle L. — that occurs both in the coastal regions of tropical and subtropical America and in the corresponding habitats of west tropical Africa, and an eastern species — R. mucronata Lam. — occurring both in tropical Asia and in east tropical Africa. It is also well-known that a few other species occur in tropical Asia; a recent revision has been given by HOU (1958). G. F. W. MEYER (1818) described from British Guiana a second American species, R. racemosa, differing in the inflorescence which is forked and 2-flowered in R. mangle and much-branched in R. racemosa. ENGLER (1876) regarded this species as a... |

J’ai récemment reçu du Dr. P. WAGENAAR HUMMELINCK de Utrecht environ 230 exemplaires (larves, nymphes et fourreaux vides) d’un Helicopsyche, recueillis par lui-même en 1936 en quelques localités de l’île de Margarita (Venezuela). Grâce au fait que les armatures génitales du ♂ et de la ♀ purent être trouvées chez une paire de nymphes, le problème de l’appartenance spécifique de cet insecte pût être élucidé; il s’agit d’une nouvelle espèce. Nous remercions vivement le Dr. P. WAGENAAR HUMMELINCK pour le matériel et pour les indications écologiques, ainsi que le Dr. D. E. KIMMINS du British Museum pour les précieuses indications qu'il nous a aimablement donné sur la forme que nous décrivons, après avoir consulté nos dessins. |

Nederlof, M.H.. |
The results of an investigation of the structure and sedimentology of Upper Westphalian and Lower Stephanian strata in the eastern end of the Cantabrian palaeozoic core (NW Spain), are presented. The sediments, shales, sandstones, limestones and coal seams occur in three main associations: the orthoquartzite-carbonate, the turbidite and paralic associations. Two facies are dstinguished: a western, without turbidites, with relatively many coal seams and an eastern, with turbidites and a few coal seams. Some evidence for a zone of less subsidence is present. This zone separates the two facies. The western and eastern facies are represented by the rocks in the Sierra Corisa and Redondo synclines respectively. Between the two synclines occurs a zone of long... |

Voo, E.E. van der. |
Op 16 mei vond ik in de gemeente Wilnis op de westhelling van de Westveense kade van de Kromme Mijdrecht een vrij dichte vegetatie van Carex reichenbachii. Volgens de auteurs van de Flora Neerlandica (I, 3, 1954) „is de plant zeker vaak over het hoofd gezien.” Dit is wel aannemelijk, omdat de habitus doet denken aan Carex ligerica of aan een nog niet volgroeide C. brizoides op overeenkomstige standplaatsen. Maar in het onderhavige geval, waarbij een soort van de sectie Arenariae (behalve dan C. disticha) op een kade in het Hafdistrict werd aangetroffen, voelde ik mij door deze merkwaardige groeiplaats wel gedwongen, de plant wat nauwkeuriger te onderzoeken. Onmiddellijk vielen daarbij de gekromde aartjes op, De determinatie gaf, hoewel de urntjes nog niet... |

SYNOPSIS The type slide of the species Fedrizzia helleri briefly described by Oudemans 1929 from Paramaribo, Dutch Guiana, but never figured, has been re-examined. The species is now shown to belong not to the genus Fedrizzia Canest. (fam. Fedrizziidae) but to the genus Klinckowstroemiella Turk 1951 (fam. Klinckowstroemiidae). The species Fedrizzia helleri was briefly described by Oudemans 1929 as follows: "Fedrizzia helleri nov. sp. Er is geen scherp begrensd sikkelvormig scutum verticale; wel is dit gedeelte naar den voorrand membraneus; die voorrand is niet zuiver rond, maar iets golvend; er zijn 4 stralende vertikaalhaartjes op geplaatst, die op gelijke afstanden van elkander staan. Verder is de rug haarloos. ♀ genitaalopening trapezoidaal, vóór bijna... |

The systematic position of the western hamster, Cricetus cricetus canescens, has been a subject of discussion and criticism ever since NEHRING (1899, pp. 1—2) described the hamster occurring in Belgium west of the Meuse as a separate variety. The present paper is a new effort to throw more light on the interesting question concerning the systematic characters by which the western hamster can be distinguished from the typical form described from central Germany. For a better understanding of the present study a brief survey of the main points in the historical development of this problem follows here. According to NEHRING the main characters in which his new variety, Cricetus vulgaris var. canescens, differed from the typical form, were: (1) the dark... |

The scope of the present paper is primarily to give a taxonomical revision of the genus Canarium. Furthermore, attention has been paid to some subjects of a more general nature, mainly regarding morphology and geography, without, however, claiming completeness. The last complete revision of the genus was published by Engler in 1883 (in DC. Mon. Phan. 4, 101—151). Of course this is now for the greater part out of date. The later revisions by the same author in E. & P., Nat. Pfl. Fam. ed. 1, 34, 1896, 238—242, and ed. 2, 19a, 1931, 443—450, are not really monographs; moreover, they lost in value by the introduction of a subdivision which was mainly based upon unessential characters. |

In this article the results of a study on boulder-clay in the neighbourhood of Winschoten (N.E. Netherlands) are communicated (Chapter I). The underlying sediments of the boulder-clay in this area consist of fine preglacial sands and black clay. In the nuclei of the many drumlins a strongly ice-pushed boulder-clay may be encountered (Chapter II). Palynological analysis showed the pollen content of the boulder-clay to be very small. In a few samples more pollen was found (Plates I and II), but in these cases there appeared to be an admixture of black clay, obviously picked up by the land-ice. This black clay (the so-called potklei or pottery clay) is very humic and resembles the Lauenburg clay from Germany, but is younger. Using pollen analysis only one... |

Van 4-11 Juli 1959 werd door de B.S.B.I. een excursie gehouden naar N.W.- Frankrijk (Pas de Calais, Somme, Seine-Maritime) onder leiding van Dr. Francis Rosé (Londen). Behalve door circa 20 Engelsen werd aan de gehele excursie deelgenomen door Prof. Jovet (Parijs), terwijl enige andere Franse botanici, veelal amateurs, gehun durende enkele dagen door hun locale kennis diensten bewezen. Bovendien was België door één deelnemer en Nederland door beide ondergetekenden vertegenwoordigd. |

Heterophylly is frequent in Dendrophthora and Phoradendron, and may take many forms. The concepts prophyll, cataphyll, and scale-leaf are briefly discussed and defined as to usage in the Phoradendreae. Various morphological details of patterns of heterophylly, flower orientation and seriation, fusion of prophylls, phyllotaxy, sex distribution and inflorescence position are traced as far as the available material permits. A typology of inflorescences in these two genera is proposed, based on flower seriation. Anatomical observations on a few species of both genera have revealed striking and unsuspected structural differences between the inflorescences of some seemingly related species, but also similarities which cross the intergeneric boundary. The... |

Two small but interesting collections of octocorals from the northeastern coast of South America have recently come into my hands through the U.S. Fish and Wildlife Service, one of them from a survey conducted by the Government of Surinam, the other from exploratory work of the U.S. Fish and Wildlife Service. The first was obtained off the coast of Surinam by Mr. J. C. HIGMAN, U.S. Fish and Wildlife Service observer aboard the motor vessel “Coquette” during the course of exploratory shrimp investigations. The second was obtained between Trinidad and the Amazon River, Brazil, through the efforts of Dr. GILES W. MEAD during the course of cruise 47 of the exploratory vessel “Oregon.” Because there is so little information available dealing with the fauna of... |

After the publication of the Araceae in the Flora of Suriname 1.2 (1953), p. 1-80, a number of rare and new species have been collected. Some of these were collected by Dr. J. Lindeman between 1953 and 1955, the remaining by the present authors, who visited Suriname from November, 1955, to March, 1956. Field observations by the authors clearly indicated the fragmentary status of our knowledge of Suriname Aroids. The reasons for this are to be sought in the difficulties involved in collecting and preserving. Also, a number of species may not flower over a period of several years. The inflorescences of many lianas are often almost inaccessible. A source of confusion is the variability in the leaves of a species. The following is an enumeration of species... |

During 1957 two important collections of fishes were obtained from off the coast of Suriname and adjacent regions. The first of these was made by the motor vessel “Coquette”, a commercial shrimp trawler which engaged in exploratory work for the Government of Suriname. Mr. JAMES B. HIGMAN of the United States Fish and Wildlife Service was invited to accompany the “Coquette” during part of this work, and the collection of fishes which resulted was due largely to his efforts. The second collection was obtained by the motor vessel “Oregon”, exploratory vessel of the United States Fish and Wildlife Service. During November, 1957, the “Oregon” occupied over a hundred trawl stations along the northern coast of South America between Venezuela and the Equator. Most... |

Arx, J.A. von. |
Plochmopeltis intricata (Ellis & Mart.) Theiss., the type species of the genus Plochmopeltis Theiss. occurs on the underside of leaves of Quercus virginiana var. virescens and Quercus laurifolia. The fungus grows superficially, with flattened ascomata which are not covered with a perithecial wall. The asci are surrounded by paraphysoids, which are brown and furcate into short branches at their apices. A new species, collected on leaves of Olea americana is described as Plochmopeltis ellisii v. Arx. The genus Plochmopeltis is related to Schizothyrium Desm. and Phillipsiella Cooke, and should be placed in the Dothiorales. |
