During my stay I collected materials for the Rijksmuseum van Natuurlijke Historie at Leiden, paying special attention to the land- and freshwater Mollusca. This paper contains the first results of the examination of the Mollusca collected.\nMy Danish friends Dr. Gunnar Thorson and Dr. Helge Vols\xc3\xb8e generously put at my disposal the non-marine Mollusca they collected during their stay in the Canaries. When the material has been worked up, duplicates will be deposited in the Zoological Museum at Copenhagen.\nI am indebted to several persons who helped me in various ways in the investigations here published. Prof. Dr. N. Hj. Odhner (Stockholm) very kindly put at my disposal a MS list of all the Mollusca of the Canary Islands and their distribution, which he had compiled for private use. Mr. Hugh Watson (Cambridge) never failed to help me by examining or lending specimens, and in detailed letters gave me the benefit of his great experience.\nDuring my stay in Paris in March 1950 Dr. G. Ranson and Dr. A. Franc put at my disposal for examination the Canarian slugs present in the Mus\xc3\xa9um

Description: The first result of this survey of the wide genera which have endemic species in New Caledonia is certainly to confirm the impression that there is indeed a noteworthy geographical association between Madagascar and that island, even if it is only a particular aspect of a more general relationship between Madagascar and Australasia as a whole.\nBut the survey gives prominence also to another point, namely the unexpectedly small part that tropical Africa plays in the distribution of the genera reviewed. It almost seems as if there is some factor of exclusion affecting that great region, and there is no indication of any corresponding degree of relation between tropical Africa and New Caledonia such as has been detected between the latter and Madagascar.

Description: Though the new names published in Thunberg\xe2\x80\x99s \xe2\x80\x9cFlorida\xe2\x80\x9d have been entered in the Index Kewensis, few botanists have tried to verify the status and synonymy of the new species proposed in this 2-thesis booklet. Thunberg\xe2\x80\x99s names were entered in Juel\xe2\x80\x99s \xe2\x80\x9cPlantae Thunbergianae\xe2\x80\x9d (1918, 412 pp.).\nThe diagnoses are generally too short and vague to allow a definite opinion. Only Schott, Mueller Arg., and F. E. Wimmer have examined material of resp. the Araceae, Euphorbiaceae, Campanulaceae.

Amshoff started the revision of the Javanese Urticaceae, but left the definitive preparation to me.\nUrtica dioica L. and U. urens L. have been erroneously recorded for Java (Miquel, Fl. Ind. bat. 1\xc2\xb2, 1859, 227; Koorders, Exk. Fl. Java 2, 1912, 126). To my knowledge no specimens were ever collected there nor elsewhere in the Malay Archipelago.

Description: Little attention has been paid till now to the algae, transported to the Netherlands coast on drifting objects. About a century ago T. D. Vrijdag Zijnen and G. Bisschop (near Scheveningen, \xc2\xb1 1845), and L. H. Buse (between Wijk aan Zee and Zandvoort, \xc2\xb1 1840\xe2\x80\x941847) were the first to pay attention to this subject. The material collected, especially that by the first two investigators, is mentioned in the Prodromus Fl. Bat. (1853). The book of Van Goor (1923) contains a chapter on these algae, in which, however, only few new observations occur. The author is much indebted to Dr Josephine Th. Koster for her kind help, as well as to Dr S. J. v. Ooststroom. The material, collected by Vrijdag Zijnen, Bisschop and Buse is almost completely present in the collections of the \xe2\x80\x98Rijksherbarium\xe2\x80\x99 and the \xe2\x80\x98Koninklijke Ncderlandse Botanische Vereniging\xe2\x80\x99, Leiden. The material, collected during the last few years has for the greater part been brought together by the present author, and furthermore especially by K. Swennen (Den Helder), J. Stock (Amsterdam), A. Mulder (Haarlem) and P. Leenhouts (Scheveningen). This material belongs to the collection of the Rijksherbarium, Leiden, but most of it is, for the time being, put under the charge of the \xe2\x80\x9cComit\xc3\xa9 ter Bestudering van de Nederlandse Mariene Flora en Fauna\xe2\x80\x9d (\xe2\x80\x9cCommittee on the Netherlands\xe2\x80\x99 Marine Flora and Fauna\xe2\x80\x9d) and temporarily preserved in \xe2\x80\x9cHet Filiaal\xe2\x80\x9d, Leiden.

Description: This paper presents the results of the examination of a fairly big collection of mollusca from the island of Mandul, north of Tarakan, East-Borneo. The material was collected by Dr. Van Holst Pellekaan while investigating the geology of Mandul in the service of the \xe2\x80\x9cBataafsche Petroleum Maatschappij\xe2\x80\x9d (Royal Dutch/Shell). It was sent to Prof. K. Martin of Leyden for closer examination, and afterwards was embodied into the collections of the Leyden Geological Museum.\nProf. Martin recorded the results of his preliminary examination, which excluded the bivalves, in a report to the \xe2\x80\x9cBataafsche\xe2\x80\x9d, dated 12th January 1917. He came to the conclusion that the fossils were of a Pliocene age.

Description: Though Schlegel (1866, p. 200) as well as Hartert (1898, p. 135) pointed out that Carpophaga paulina, described by Bonaparte (1850, p. 35) and now known as Ducula aenea paulina (Bp.), originating from the Sula Archipelago (East of the East Coast of Celebes) seemed not quite similar to birds from Celebes, lack of sufficient material refrained these authors from separating Sula birds. But this was done by Siebers (1929, p. 152/3) who separated them under the name Ducula aenea sulana, on account of their smaller wing measurements and the darker (more chestnut coloured) nuchal patch. The Sula birds should be also smaller than nuchalis from the Philippines and (doubtful) pulchella from Togian 2) which, according to Siebers, should belong to the same "Formenkreis" as paulina and sulana.\nSiebers compared 8 birds from Sula (1 \xe2\x99\x82, 5 \xe2\x99\x80 and 2 sex. inc.) in which the length of the wing varied from 208 to 216 mm with 5 specimens (3 \xe2\x99\x82 and 2 \xe2\x99\x80) originating from Celebes (Paloppo and Bone) having wings varying from 218 + x to 234 mm and with 7 skins (4 \xe2\x99\x82 and 3 \xe2\x99\x80) from Muna and Buton with wing measurements diverging from 232 to 248 mm.\nBesides the 20 birds studied by Siebers I could examine 18 more skins of these pigeons, viz., 3 from the Sula Islands, 2 from Pulau Peleng (island off Northeast Coast Celebes), 4 from Bumbulan (North Celebes), I from North Celebes (exact locality unknown), 1 from Kulawi (Central Celebes), 2 from Bone (South Celebes; Siebers\' statement that Bone is situated in North Celebes must be a slip of the pen), 2 from South Celebes (exact locality unknown), 1 from Mara (Mare?, South Celebes) and 2 from Muna (island off the Southeast Coast Celebes). When comparing these 38 skins (31 specimens from the Buitenzorg Museum and 7 from

Description: In a paper on some birds from Sumatra in the Leiden Museum Dr. Junge (1948, pp. 314-15) lists two males of Limosa lapponica baueri Naum. taken by Mr. Van Heurn on the beach at Tandjong Tiram in the Deli district on 14 November 1921. In a short discussion on this record he refers to the fact that Vorderman (1890, p. 416) gives this species as probably occurring in Sumatra, and subsequently Robinson & Kloss (1923, p. 326) and Chasen (1935, p. 37) list it without query or comment. Dr. Junge adds that he failed to find the reference on which the later authors decided that the bird was definitely known from Sumatra. It is probable that no such reference exists and that Dr. Junge\'s paper constitutes the first authentic published record of the occurrence there of the Eastern Bartailed Godwit. The point at issue is a general one which has puzzled other workers in this field, and it would seem to be of interest to outline the situation briefly.\nRobinson & Kloss published two lists of the birds of Sumatra, the first in 1918, containing 527 birds, and the second in 1923, giving 574 birds. In a note to their first list the authors (1918, p. 284) make the following comment on their treatment of the "Charadrii formes" (= Suborder Charadrii), "In this group Vorderman records with certainty only 14 species that are found on the mud-flats of the Strait of Malacca with one or two exceptions".\nIt is clear that by mud-flats of the Strait of Malacca they mean the flats on the eastern (Malay Peninsula) side of the strait. They disallow 3 of the birds given by Vorderman, but make their own total up to 30. At that time they had apparently no reliable Sumatran records for the great majority of the 19 species which they thus added to the Sumatran list. The same procedure was followed in compiling the second list, published in 1923,

Description: The genus Podolestes, as far as at present known, is confined to the Malaysian subregion of the Indo-Australian Archipelago. Descriptions and drawings of structural details of four species are to be found in two of the writer\'s previous papers on Malaysian dragonf lies, viz.: New and little known Odonata of the Oriental and Australian Regions.\nTreubia, 15, 1935: 177-183, fig. 1-3.\nDescriptions and records of South-East Asiatic Odonata (II). Ibid. 17, 1940: 347-350, fig. 4-5.\nThe species of Podolestes have been found in marshes and along muddy creeks flowing through wooded areas in low country. Owing to their retiring habits the insects are but seldom encountered and all species are rare in collections. Little or nothing is known of their life-histories, and the larva is still unknown.\nThe six known members of the genus, two of which are here described for the first time, may be distinguished by the following Key to the species. 1. Dorsum of thorax uniform metallic bronzy black. Labrum, mandibles and genae shiny black. Ante-alar triangles bronzy-black, unmarked. Nervure Ac situated much nearer Ax2 than Ax1; nervure Ab complete, meeting Ac at the wing-margin. Quadrilateral short, markedly widened distally, costal and distal sides approximately equal in length in fore wing. Three to four postquadrangular antenodal cells. Male anal appendages of slender build, blackish in colour; superior pair a trifle longer than the inferiors; apex of inf. app. expanded, truncated and slightly notched 2. \xe2\x80\x94. Dorsum of thorax with two pairs of light-coloured spots on mesepisternum, and sides with an oblique band extending from below the spiracle upwards as far as the dorsal

Description: La r\xc3\xa9gion que j\xe2\x80\x99ai \xc3\xa9tudi\xc3\xa9e et relev\xc3\xa9e est situ\xc3\xa9e dans les Alpes fran\xc3\xa7aises, \xc3\xa0 environ 4\xc2\xb0 longitude est et 50\xc2\xb015\xe2\x80\x99 latitude nord, et \xc3\xa0 environ 2000 m\xc3\xa8tres d\xe2\x80\x99altitude. Elle fait partie de la cha\xc3\xaene dite \xe2\x80\x9echa\xc3\xaene de Belledonne\xe2\x80\x9d qui s\xe2\x80\x99\xc3\xa9tend des massifs de Beaufort et du Grand Mont dans le N N E jusqu\xe2\x80\x99\xc3\xa0 ceux du Taillefer et de la Mure dans le S S W. Cette cha\xc3\xaene forme du point de vue g\xc3\xa9ographique comme du point de vue g\xc3\xa9ologique le prolongement m\xc3\xa9ridional de la cha\xc3\xaene des Aiguilles Rouges et de la cha\xc3\xaene du Mont Blanc. Celles-ci font partie de la zone externe des massifs cristallins des Alpes, dont le prolongement en Suisse est connu sous le nom de \xe2\x80\x9emassifs centraux des Alpes\xe2\x80\x9d. On entend par l\xc3\xa0 les cha\xc3\xaenes ant\xc3\xa9-alpines, et principalement hercyniennes des Alpes, constitu\xc3\xa9es de roches du Houiller d\xe2\x80\x99une part, de formations ant\xc3\xa9rieures d\xe2\x80\x99autre part, et recouvertes enfin de s\xc3\xa9ries d\xe2\x80\x99\xc3\xa2ges m\xc3\xa9sozo\xc3\xafque et permien. Dans le sud, cette cha\xc3\xaene hercynienne se divise de nouveau en deux branches, dont la plus orientale, celle des Grandes Rousses, aboutit \xc3\xa0 la partie d\xc3\xa9vers\xc3\xa9e vers l\xe2\x80\x99est, dans le massif du Pelvoux. Taillefer et la Mure forment le pivot le plus avanc\xc3\xa9 de cet arc, et en effet ce dernier massif dispara\xc3\xaet partiellement vers le S W sous le manteau s\xc3\xa9dimentaire du D\xc3\xa9voluy (cf. fig. 1). Le massif de Belledonne proprement dit, avec son point culminant: le Grand Pic de Belledonne, qui atteint \xc3\xa0 quelques m\xc3\xa8tres pr\xc3\xa8s les 3000, forme le tron\xc3\xa7on central de cette cha\xc3\xaene et se trouve \xc3\xa0 quelques kilom\xc3\xa8tres \xc3\xa0 l\xe2\x80\x99est de Grenoble dans le d\xc3\xa9partement de l\xe2\x80\x99Is\xc3\xa8re. Il est limit\xc3\xa9 \xc3\xa0 l\xe2\x80\x99ouest par l\xe2\x80\x99Is\xc3\xa8re et le Drac; au sud par la Romanche; \xc3\xa0 l\xe2\x80\x99est par l\xe2\x80\x99Eau d\xe2\x80\x99Olle et au nord par la vall\xc3\xa9e de Laval et le Col de la Coche.\nLes Lacs Robert sont \xc3\xa0 peu pr\xc3\xa8s situ\xc3\xa9s au centre du Massif de Belledonne, dans un cirque encoch\xc3\xa9 dans le ralliement m\xc3\xa9ridional de la cha\xc3\xaene occidentale \xc3\xa0 la cha\xc3\xaene principale du massif. Cette cha\xc3\xaene principale, comprise entre le Jasse Bralart au N et le Petit Vent au S, limite la r\xc3\xa9gion lev\xc3\xa9e \xc3\xa0 l\xe2\x80\x99est, tandis que la Botte et le lac Achard la limitent au sud. A l\xe2\x80\x99ouest elle s\xe2\x80\x99arr\xc3\xaate au pied de la Croix de Chamrousse, le pivot m\xc3\xa9ridional, et du Grand Eulier, le contrefort septentrional de la cha\xc3\xaene secondaire; et au nord audessus de la Prairie de l\xe2\x80\x99Oursi\xc3\xa8re. Cette r\xc3\xa9gion a une largeur de 3 km et une longueur de 4 km environ. Le Grand Sorbier dans la cha\xc3\xaene principale, avec ses 2522 m. en est le point culminant. L\xe2\x80\x99impraticabilit\xc3\xa9 du terrain fixa des fronti\xc3\xa8res plus ou moins naturelles au lever. En particulier le flanc E de la cha\xc3\xaene principale, qui domine la vall\xc3\xa9e de Baton, \xc3\xa0 part quelques sentiers, n\xe2\x80\x99est pas accessible sans danger, \xc3\xa0 cause du mauvais \xc3\xa9tat de la roche schisteuse. Il en est de m\xc3\xaame pour la pente occidentale du Grand Eulier et du Casserousse, tandis que le flanc m\xc3\xa9ridional du Petit Vent et de la Botte est un des versants de la gorge profonde de 2000 m. o\xc3\xb9 coule la Romanche. C\xe2\x80\x99est \xc3\xa0 cela qu\xe2\x80\x99est d\xc3\xbb le nombre restreint d\xe2\x80\x99observations faites sur quelques parties de la p\xc3\xa9riph\xc3\xa9rie.
