| Apart from the common cricetid fauna, the site of Vieux-Collonges contains a number of rare forms: Lartetomys, Melissiodon, Neocometes, and Anomalomys. This scarce material is described and compared with material from other European localities. The stratigraphie position of Vieux-Collonges is discussed briefly. En plus des Cricetodontinae et Cricetinae communs, il existe à Vieux-Collonges plusieures espèces d'autres groupes de Cricetidae, représentées par des matériaux peu nombreux. Il s'agit de Lartetomys mirabilis, Lartetomys zapfei, Melissiodon aff. dominans, Neocometes similis et Anomalomys sp. Cettes formes sont décrites, et leur valeur pour la corrélation de Vieux-Collonges avec d'autres gisements de mammifères miocènes est discutée. |

| Plants have evolved annual and perennial life forms as alternative strategies to adapt reproduction and survival to environmental constraints. In isolated situations, such as islands, woody perennials have evolved repeatedly from annual ancestors1. Although the molecular basis of the rapid evolution of insular woodiness is unknown, the molecular difference between perennials and annuals might be rather small, and a change between these life strategies might not require major genetic innovations2,3. Developmental regulators can strongly affect evolutionary variation4 and genes involved in meristem transitions are good candidates for a switch in growth habit. We found that the MADS box proteins SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1) and FRUITFULL... |

| A comparative study is made of four chelicerate classes: Apatellata (Solifugae and Pseudoscorpionida), Arachnida s. str. (both groups of Uropygi, i.e. Holopeltida and Schizomida, Amblypygi and Araneida), Scorpionida and Xiphosura. Methods, principles and terminology, adopted in this paper, correspond with those of parts I -111 of the present series of comparative studies in Chelicerata. Special attention is paid to segmentation of the body, respiratory organs, orifices of coxal glands, mouthparts, and appendages. The evolution of these structures is studied, and the relationships of the chelicerate classes and subclasses are reinvestigated and discussed. |

| The Microascaceae are briefly discussed and a key to the accepted genera is given. The new species described are Pithoascus langeronii with an arthric anamorph Arthrographis langeronii) and Petriellidium fimeti with a Graphium-like anamorph. Pure culture descriptions are given of the psychrophilic Leuconeurospora pulcherrima and also of Faurelina elongata which has an arthric anamorph with 2-celled conidia. |

| The first volume of this series was published in 1991, and reviewed in Blumea 38, p. 216. The treatments of volumes 2 and 3 are each based on a doctor’s thesis by the first author, elaborated under supervision of Dr. Panigrahi. Volume 2 contains regional revisions of six genera: Prunus, Prinsepia, Maddenia, Rosa, Malus, and Pyrus. Prunus is taken in the inclusive sense and has 38 species in India, including a number of non-indigenous but cultivated and sometimes naturalized species. Prinsepia and Maddenia have one species each in the region covered. Rosa is a well represented genus in India and 37 species are recognized, including several non-native garden roses. Of the Maloideae only Malus (4 species) and Pyrus (4 species) are treated. |

| Gentianella campestris (L.) Börner opnieuw in Zuid-Limburg gevonden. Tijdens een van mijn vele wandelingen, die ik in het najaar pleeg te maken op de bij de floristen in Zuid-Limburg goed bekende Kunraderberg, gem. Voerendaal, ontdekte ik op 1 november 1980 twee kleine, bloeiende exemplaren van Gentianella campestris, de brede duingentiaan. Samen met G. germanica en G. ciliata komen er nu drie soorten gentiaan op de Kunraderberg voor, een voor Nederland unieke situatie. Na de wandeling heb ik direct contact opgenomen met de onlangs overleden dr. S.J. Dijkstra (Schaesberg) om hem van de vondst op de hoogte te stellen. Groot was mijn verbazing, toen ik van hem vernam dat ook hij enkele exemplaren van G. campestris op de Kunraderberg had waargenomen, echter... |

| Several aspects of the ecology of Jameson’s green mamba Dendroaspis jamesoni jamesoni (Traill, 1843), a large-sized arboreal elapid snake, are studied in southern Nigeria. This species 18 common and widespread in the region studied. On the basis of the analysis of both the habitats of capture of the various specimens and the results of a logistical regression model, it seems that this species inhabits a wide variety of habitats (including secondary forest patches and the plantation-forest mosaic), and that its local distribution is not influenced by the Presence of any macrohabitat parameter. Green mambas were observed both in the dry and in the wet season, without any statistical bias toward a particular season. Adult sex-ratio was aPproximately 1 : 1.... |

| The sinus rhomboidalis sacralis or sinus lumbosacralis as it is named by Ariens Kappers (1920) is an interesting anatomical part of the lumbosacral region of the avian spinal medulla. It is found in birds only and neither in reptiles nor in mammals. Fig. 1 shows the lumbosacral part of the spinal medulla of Phoenicopterus Pig. 1. Spinal medulla of Phoenicopterus, dorsal view, with sinus lumbosacralis and corpus gelatinosum. From Imhof (1905). seen from the dorsal surface and Fig. 2 represents a diagrammatic transverse section through the lumbosacral part. These figures show some peculiarities that are found in birds only. All vertebrates with hind limbs have a lumbosacral enlargement of the spinal medulla, but in birds this enlargement has become more... |

| Mr. BRASS’S New Guinea collection has yielded valuable data to our knowledge of the Verbenaceae. He discovered one new genus (Archboldia), 3 new species (Clerodendron Brassii, C. populneum and Premna inaequilateralis) and some interesting additions to the area’s of earlier described species, among which the rediscovery of Faradaya chrysoclada, and the discovery of two species new for South New Guinea (Premna sessilifolia and Teysmanniodendron bogoriense) and of one more for the whole island ( Glossocarya Hemiderma). |

| In de collectie van het Leidsche Museum bevindt zich een Centronotus fasciatus Bl. & Sch., volgens de opgave op het etiket afkomstig van de Hollandsche kust. De kenmerken van dit individu, dat 230 mm. lang is, zijn: De hoogte van het langwerpige lichaam gaat 9 7/12 en de lengte van den, evenals het lichaam zijdelings plat gedrukten, kleinen kop 10 5/11 maal in de lichaamslengte, de staartvin inbegrepen. De lage, lange rugvin begint boven den aanvang der borstvinnen en loopt tot aan de staartvin; zij heeft 89 stekels, die bij dit individu de abnormaliteit vertoonen niet allen verhard te zijn. De voorste 55 zijn slap, de volgende 17 zijn hard en scherppuntig, de laatste 17 zijn weder slap. De harde stekels zijn geelachtig, doorschijnend, glanzig, de... |

| Many years have passed since short descriptions were published of the land and fresh & brackish-water habitats sampled in the Caribbean during the author’s three zoological collecting trips in 1930, 1936/37, and 1948/49 (these Studies, vols. 1 and 2, 1940, and vol. 4, 1953). Sampling was continued in 1955, 1963/64, 1967, 1968, 1970 and 1973. Data on the marine and saltpond habitats from which material was gathered were published in Studies 51, 1977. Collecting was done single-handed and often rather incidentally, as a rule with no other equipment than a knife, forceps, a beetle-sieve and a fine-meshed dip-net, the author confining himself to those places which presumably would yield a more or less representative sample within a short time. Yet, the... |

| Pagurus loxochelis a été décrit et figuré par C. Moreira (1901, p. 24 pl. 2 fig. 1, 1a-f) d'après un unique exemplaire mâle provenant de Bahia. L'auteur ne plaçait pas sans hésitation cette espèce dans le genre „Pagurus" Fabricius (= Dardanus Paulson) 1). Il constatait en effet que le flagelle des antennes était orné de longues soies, alors qu'il était nu chez les autres "Pagurus". Considérant cependant que Miers (1881, p. 275-276) avait décrit Pagurus imperator et P. granulimanus comme possédant des antennes, non pas nues, mais faiblement ciliées, il choisissait d'étendre l'acception du genre, plutôt que d'en décrire un nouveau pour une unique espèce. Précisons immédiatement que la raison invoquée par Moreira pour rattacher P. loxochelis au genre... |
