A discussion of Malayan and Indonesian shrews of the genus Crocidura (Insectivora: Soricidae) Naturalis
Jenkins, P.D..
An investigation was made into the systematics of white-toothed shrews (Crocidura) occurring in Malaya and Indonesia. Most of the forms recorded from this area have been found to represent one of four species: C. fuliginosa (Blyth, 1855), C. attenuata Milne-Edwards, 1872, C. maxi Sody, 1936 or C. monticola Peters, 1870, while the status of a few others remains unresolved at this stage. Each species is discussed and distinguishing features are given in tabular form.

A discussion of the Ehrharteae (Gramineae) with special reference to the Malesian taxa formerly included in Microlaena Naturalis
Willemse, L.P.M..
The genera Microlaena R. Br., Petriella Zotov, and Tetrarrhena R. Br. are included in Ehrharta Thunb. (Gramineae-Ehrharteae), which necessitates four new combinations in the latter. In Malesia Ehrharta is represented by two taxa originally included in Microlaena: E. diplax F. v. Muel. var. giulianettii (Stapf) L. P. M. Willemse (M. giulianettii Stapf) and E. stipoides Labill. var. stipoides [M. stipoides (Labill.) R. Br. var. stipoides]. Descriptions of and notes on these taxa are given.

A discussion of the size of recent red deer (Cervus elaphus L.) compared with prehistoric specimens Naturalis
Walvius, M.R..
Red deer ( Cervus elaphus L.) are known from many prehistoric sites in Western Europe; a number of these are usually of great size as compared with contemporary animals. This essay is an attempt to summarize the literature concerning the size of the prehistoric red deer in comparison with the recent species and to discuss the different influences of the habitat (extent and character of the biotope, food, climate) on the dimensions of red deer. It is the intention that it should attribute to a better understanding of the factors that may have caused the great size of many prehistoric red deer and to try and find out if a similarity between the variation during the course of postglacial times and the local variation in relation to the habitat exists. Most...

A do-it-yourself altimeter for trees Naturalis
Geesink, R..
Commercially available tree altimeters are expensive and heavy, and my personal experience with these instruments is thus minimal. During my last expedition I only used it now and then in the base camp to correct my ’feeling for estimation’. I have little doubt that colleagues will recognize these feelings. After my return I regretted this attitude to some extent and tried to design a cheap and light alternative device. It is drawn on the next page, and easy to construct: Make a copy of the drawing. Photocopies are generally not exact enough, causing differences to 5 m in this scheme, due to barrel- and cushionshaped distortion by the lens. I advise to copy the drawing by hand on transparent paper. Glue this copy (preferably with epoxy-resin to make it...

A fabric study of Lherzolites Naturalis
Collée, A.L.G..
The solution of the problem whether the ultrabasic inclusions in lavas are accumulation products of early crystallized minerals of the lavas in which they occur, or fragments of the earth’s peridotite shell carried to the surface by the eruptive force of the lavas, largely depends on the answer to the question whether these inclusions are tectonites or not. The structure of the specimens from Auvergne (France), which formed the main subject of this study, has been proved conclusively to be of a tectonic nature, from the macroscopically visible intersecting slip planes which are definitely younger than the banding of the specimen, as well as from microscopic evidence that suggests that both the olivine and enstatite crystals are concentrated in the...

A field guide to the Silurian Echinodermata of the British Isles: Part 1 - Eleutherozoa and Rhombifera Naturalis
Lewis, D.N.; Donovan, S.K.; Crabb, P.; Gladwell, D.J..
The Palaeozoic echinoderms of the British Isles are most diverse in the Silurian and Lower Carboniferous. This guide discusses and illustrates members of all major groups of echinoderms, apart from the crinoids, from the Silurian of these islands. Groups considered include the echinoids (five taxa), ophiuroids (ten taxa) and asteroids (thirteen taxa), and the extinct ophiocistioids (three species) and rhombiferan cystoids (nine species).

A field impression of the lichen and bryophyte zonation on Mount Kinabalu Naturalis
Sipman, H.J.M.; Tan, B.C..
Vegetation descriptions of Mount Kinabalu (4101 m), the highest mountain in tropical Asia between the Himalayas and New Guinea, have resulted in different, conflicting zonations. Some stress more on floristic affinities, others more on physiognomy. A lowland zone reaching to about 1000 m is usually distinguished. The next 2000 m comprising the mountain forests are treated in many different ways. A summit zone (above 3800 m) is recognized rather often (cf. Stapf, 1895; Gibbs, 1914; Meijer, 1963; Van Steenis, 1964; Menzel, 1988). In our opinion the most convincing is the zonation proposed by Van Steenis, who stressed the floristic composition. This comprises three zones: 1. the foothill zone below 1000 m; 2. the montane zone from 1000 to 2500 m; 3. the...

A first contribution to our knowledge of the flora of the Talaud Islands and Morotai Naturalis
Holthuis, L.B.; Lam, H.J..
The Talaud Islands are forming part of the Malay Archipelago, being situated north of Celebes and the Moluccas, south of Mindanao and east of the Sangihe group, between 3°45’ and 5°35’ N. lat. and 126°32’ and 127°10’ E. long. The main group consists of three larger islands, viz. Karakelong, Salebaboe and Kaboeroeang. The Nenoesa islands, a group formed by the small islands of Garete, Karaton, Merampi, Mengkopoe, Intata, Kakelotan and Maroh are situated northeast of the main group, including also Miangas (Palmas), an islet about 65 miles north of Karakelong, near Mindanao.

A fissitunicate ascus mechanism in the Calosphaeriaceae, and novel species of Jattaea and Calosphaeria on Prunus wood Naturalis
Damm, U.; Crous, P.W.; Fourie, P.H..
During a survey of Prunus wood from South Africa, isolations were made of three presumably Calosphaerialean fungi that formed hyphomycetous, phialidic anamorphs in culture. In order to reveal the phylogenetic relationship of these fungi, they were characterised on a morphological and molecular (LSU and ITS rDNA) basis. Two isolates that formed a teleomorph in culture are newly described as Calosphaeria africana sp. nov. Although asci of Calosphaeria are characterised by having non-amyloid apical rings, two functional wall layers were observed in asci of C. africana, which has hitherto not been observed in any member of the Calosphaeriaceae. However, Calosphaeriaceae (Calosphaeriales, Sordariomycetes) are not closely related to other bitunicate fungi like...

A floristic study of forests and bog vegetation, Northwestern Minnesota Naturalis
Janssen, C.R..
Single vegetation plots in forests and bogs in the deciduous and coniferoushardwood formation in northwestern Minnesota were studied according to the field methods of the Zürich-Montpellier system. Plots and species were arranged so that the greatest coincidence of occurrences was obtained. Species that show approximately similar amplitudes were united in sociological groups. Plant communities typified by these groups were placed in a hierarchy. The plant communities appear to intergrade but are not completely continuous. Definite concentrations of occurrences remain present in the ordination. Fourteen main types of vegetation are recognized. Their relations to the environment are discussed, and their relations to vegetation in other regions are indicated....

A fossil gazelle (Gazelle schreuderae nov. spec.) from the Netherlands Naturalis
Hooijer, D.A..
In 1944 Miss Dr. A. Schreuder sent me for identification a fossil horncore, which according to the accompanying letter came from a well-boring near Grubbenvorst (province of Limburg). It was found in a coarse sandy layer with gravel at a depth of 61.50 m below the surface; the topographic height of the latter is given as 24.53 m + N.A.P. (N.A.P. = sea-level at Amsterdam). Dr. J. F. Steenhuis, geologist to the Government Geological Foundation, informed me that deep borings for the water-supply of Central-Limburg have been made in the years 1918, 1919, and 1922 S. and S.E. of Grubbenvorst. Evidently we have to do with boring no. I of October 1918, which reached a depth of 83 m, the top being at 24.50 m + N.A.P. (Geological Foundation Index no. 695/4). The...

A fossil skull fragment of a walrus from the mouth of the river Scheldt (Netherlands) Naturalis
Feen, P.J. van der.
An occipito-parietal skull fragment of a male specimen of Odobenus antverpiensis (Rutten, 1907), from the mouth of the River Scheldt (Netherlands) is described and figured. The animal lived probably about the transition Scaldisian-Merxemian (Pliocene-Pleistocene). It lived in coastal marine surroundings rich in shell-bearing molluscs and is not necessarily an indication of cool conditions.

A further contribution to our Oological knowledge of the Island of Java (Indonesia) Naturalis
Hellebrekers, W.Ph.J.; Hoogerwerf, A..
The present authors independently from one another studied oological material from Java. The results of their studies are combined in the present paper. Hellebrekers deals with three collections, held by the Rijksmuseum van Natuurlijke Historie at Leiden, brought together (a) by M. E. G. Bartels and his sons (4770 shells), (b) by J. G. Kooiman (280 shells), and (c) by H. J. V. Sody (175 shells). Of these collections those made by Bartels and Sody consist almost exclusively of eggs from West Java, while that made by Kooiman originates from East Java. Hoogerwerf gives details of 1020 shells of his own collection, almost all of which originate from West Java. These were obtained after the appearance in 1949 of a paper in which he published the colour...

A further extension of Elminius modestus Darwin on the west coast of France Naturalis
Crisp, D.J..
In previous publications Bishop & Crisp (1957, 1958) described the distribution of Elminius modestus on the coasts of France, based on surveys made in 1953 and 1954. Further information including some observations made in 1955 was given by Bishop, Crisp, Fischer-Piette & Prenant (1957). Elminius was shown to be centred on three main areas; the Channel coast east of Cap de la Hague, the river systems of North Brittany, and the Rade de Brest. Further south scattered individuals only were to be found, nowhere in sufficient abundance to allow the majority to breed. Bishop & Crisp (1957) pointed aut that the scarcity of Elminius on this part of the Brittany coast was surprising, since there are numerous suitable estuaries and harbours and an...

A further Note on the Canines of Celebochoerus Naturalis
Hooijer, D.A..
The genus Celebochoerus was based by me (Hooijer, 1948) on two fragments of upper canines of rather large size, different from their homologues in Sus celebensis Müller and Babyrousa babyrussa (L.), the two living species of Suidae of Celebes. The specimens originate from Pleistocene deposits at Desa Beru, Tjabenge (Sopeng district), about 100 km N.E. of Macassar, S. Celebes, and were collected by Mr. H. R. van Heekeren, prehistorian to the Archaeological Survey at Macassar. In the meantime I have received more specimens of upper canines, collected by Mr. Van Heekeren at Desa Beru and also at Sompoh, 12 km N. of Beru. These specimens, like those first described, are surface finds and consequently more or less water-worn. They show a great deal of variation...

A generic monograph of the Meliaceae Naturalis
Pennington, T.D.; Styles, B.T..
Of all plant families the Meliaceae is among the more useful to man, chiefly for its high quality timbers and for the ease with which some species can be grown in plantations. Almost confined to the tropics, its species nevertheless pervade them, and occur, often conspicuously, in a variety of habitats from rain forest to mangrove swamp and semidesert. For its size, the family probably contains a wider range of floral and fruit structures than any comparable group. In what other family is there such a diversity of primitive ‘arillate’5 seeds, side-by-side with such an array of derived fruits and seeds, and still connected by intermediates? Or, to take the flower, where else can be found such a diversity of forms, from the minute, but structurally complex,...
