    Description: CONTENTS\nIntroduction............... 3\nSystematic survey of the Limacidae of the central and western Canary Islands 5 Biogeographical notes on the Limacidae of the Canary Islands . . . . 21 Alphabetical list of the persons who collected or observed Limacidae in the Canary Islands.............. 31\nLiterature............... 32\nINTRODUCTION\nIn the spring of 1947 I was so fortunate as to join for some 9 weeks the Danish Zoological Expedition to the Canary Islands. 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: Le texte contient l\'explication de la carte, des profils et du tableau stratigraphique. La description lithologique fait mention d\'une dolomitisation du D\xc3\xa9vonien moyen, montant quelquefois plus haut, et de quelques poudingues dans le D\xc3\xa9vonien sup\xc3\xa9rieur. Un affleurement probablement du D\xc3\xa9vonien inf\xc3\xa9rieur dans un facies gr\xc3\xa9seux et fossilif\xc3\xa8re, est exceptionnel dans les Pyr\xc3\xa9n\xc3\xa9es. Dans la tectonique on a essay\xc3\xa9 de faire une \xc3\xa9valuation des influences alpines et hercyniennes s\xc3\xa9par\xc3\xa9ment. Puisque le m\xc3\xa9tamorphisme de contact des granites de Foix et de Lacourt ne monte pas plus haut que le Gothlandien, leur \xc3\xa2ge reste incertain, quoique des dykes et sills acides traversent le Carbonif\xc3\xa8re. La min\xc3\xa9ralisation due au granit\xc3\xa9 ne monte nul part plus haut que le D\xc3\xa9vonien.
