Description: Dr. C. A. BACKER and Dr. O. POSTHUMUS, Varenflora voor Java. Overzicht deiop Java voorkomende varens en varenachtigen, hare verspreiding, oekologie en toepassingen. Uitgave van (Fern flora for Java. Conspectus of the ferns and fern allies occurring in Java, their distribution, ecology and use. Issued by) \xe2\x80\x99s Lands Plantentuin, Buitenzorg, June 1939. I\xe2\x80\x94XLVII, 1\xe2\x80\x94370, 1 Plate, 1 map and 81 text figures. \xe2\x80\x94 \xc6\x92 7.50.\nThe users both at home and abroad of Dr. BACKER\xe2\x80\x99s florae have always regretted that, however carefully these books have been prepared, most of them were imperfect in one way or another. They were either restricted to certain vegetations (weedflorae for tea and sugar-cane) or did not cover all groups of vascular plants; the \xe2\x80\x9dFlora van Batavia\xe2\x80\x9c (1907), the \xe2\x80\x9dSchoolflora voor Java\xe2\x80\x9c (1911) contain only the Dicotyledoneae-Dialypetalae, the \xe2\x80\x9dHandboek voor de flora van Java\xe2\x80\x9c (1928) contains scattered families of the Ferns and Fern Allies, Gymnosperms and many Monocotyledons. This phenomenon is probably due to the fact that BACKER is a most accurate and painstaking worker, who is inclined to refrain from publication unless he is reasonably sure to be correct; and we all know how difficult it is to reach a mental state of this description. However, BACKER has for some years been engaged in preparing with untiring and admirable energy, a new and complete \xe2\x80\x9dSchoolflora voor Java\xe2\x80\x9c, the manuscript of which is rapidly growing to maturity. When the Pteridophytes were completed as far as the regions up to 3300\xe2\x80\x99 were concerned, Dr. POSTHUMUS suggested a collaboration in order to make a complete flora of vascular cryptogams. This collaboration of our keenest connoisseur of the Java flora and our best pteridologist resulted in the book, which we have the pleasure to announce and recommend here. Together with the new. \xe2\x80\x9dSchoolflora\xe2\x80\x9c to which we may be looking forward soon, it will form the first reliable flora of the vascular plants of Java. Although the Dutch language is probably less unapproachable than the Russian one, with which Soviet botanists try to convince the world that everybody should know Russian (or that it is not necessary that other peoples should know Russian botany?), it is, I think, to be regretted that our mother tongue has been chosen for a book which many foreign botanists, notably in British Malaya and British Borneo, may desire to use. This is the more so, as the book does not only contain keys to the determination and descriptions of the 15 families, 104 genera and 515 species, but also interesting chapters on the distribution (with map), the ecology, the sociology and the use of the plants described. Also the introductory paragraphs (pp. XIII\xe2\x80\x94XXX) contain many valuable and interesting notes on the morphology; the wording of these chapters is probably not easy for those who are only little familiar with our language, as BACKER has a certain predilection for a literary style.

Description: For the incorporation of various grasses in the herbaria of our institutes, we are constantly looking for the correct names to accept, according to the priority. The study of the existing names, as they are given in the Index Kewensis, is therefore indispensable. Working in various genera of the grasses we find, however, that many names are not tenable, because they were accepted without studying the whole literature of the subject. It appeared that, various names are omitted in the Index Kewensis, and indications given in various papers are sometimes neglected.\nThus, the well-known and characteristic Aristida rhiniochloa HOCHST., already described in the year 1855 and treated by me in the Critical Revision (p. 510) and in my Monograph, is not yet given in the Index, although many of my new species are mentioned.

Description: This survey of the scorpions of the Leeward Group is based on author\xe2\x80\x99s collection and therefore includes some mainlandrecords from northern Venezuela and northeastern Colombia. Material from Cura\xc3\xa7ao, deposited in the \xe2\x80\x9cZo\xc3\xb6logisch Museum, Amsterdam\xe2\x80\x9d (A) and the \xe2\x80\x9cRijksmuseum van Natuurlijke Historie, Leiden\xe2\x80\x9d (L) has been included, and the few island-records which were found in literature mentioned. Important new localities are indicated by an exclamation-mark.\nA description of the localities may be found in the 1st and the 4th paper of this series.

Description: In preparing the volume of the Gobioidea in M. Weber and L. F. de Beaufort: The Fishes of the Indo-Australian Archipelago, several described species, collected in the Indo-Australian Archipelago or its surroundings, were not clear to me. Of a number of these the description was distinct enough to see what was meant with such a new species, but there were several species which I could not recognize from their description. Bleeker described a large number of new species, but, unfortunately, several of his descriptions are too vague to recognize the species. So many authors had described several species which proved, after comparison with Bleeker\'s type specimens or descriptions made after his types, to be either closely allied, or identical with species already described by Bleeker. In order to see whether the described species of authors were synonyms of already described species, or to reexamine the types in order to enlarge the descriptions, I visited several Museums and other Institutions in the United States of N.\nAmerica, Honolulu, Australia, Philippines, Singapore and British India.\nDuring a stay in Batavia, I had the opportunity to make colour sketches of freshly-caught specimens and to go out and collect specimens myself.\nMy visit to the different countries mentioned was made possible by a grant of the "Pieter Langerhuizen Lambertuszoon fonds", endowed by the "Hollandsche Maatschappij der Wetenschappen".\nDuring these visits I received great help and friendship of the staff of the Museums and Institutions, for which I am very thankful. Especially I am obliged to the following Directors of Museums and other Institutions and members of their staff:

Description: A few localities in which collecting has been done in 1930 (cf. Zool. Jb. Syst. 64, 1933) are included without special numbering. A capital-letter after the station-number indicates a different habitat or a comparable habitat in another locality; an ordinary-letter indicates that the same habitat has already been studied before.

Description: Much has been said of the geographical relations and the origin of the West Indian fauna, especially as to that of its vertebrates and mollusks. Mostly the islands off the Venezuelan coast, for the greater part within sight of the South American continent, remained out of question, although obvious differences between the fauna of Cura\xc3\xa7ao and that of the adjacent mainland were rather quickly noticed and its affinity towards the fauna of the Greater Antilles even emphasized (Bland, 1861; Baker, 1924).\nWithout going into the West Indian fauna as a whole, or the current theories that try to explain its distribution, an attempt is being made to find out what palaeogeographical indication is given by the fauna of the Leeward Group, by careful examination of the distribution of its mammals, reptiles, amphibians, fishes and mollusks, \xe2\x80\x94 these being the only groups, perhaps with exception of the birds, which are sufficiently well known to serve as a base for zoogeographical considerations. Biocoenoses were not studied, only the distribution of species and subspecies was taken into account. The biotopes usually being very small and scattered by many isolating factors formed by accidental circumstances, the fauna being very poor and the biology of the species practically unknown, it will be clear that we have to be unpretentious in our aim and very careful in our conclusions.

Description: Although the islands of Cura\xc3\xa7ao, Aruba and Bonaire have received the attention of many naturalists, from the beginning of the West-Indian trade until to-day, it was not before 1924 that a suitable publication on the \xe2\x80\x9cLand and Freshwater Molluscs of the Dutch Leeward Islands\xe2\x80\x9d was written by Horace Burrington Baker. I should like to express my appreciation of this work, which not only facilitated my studies, but, at the same time, forced me to collect the landshells of these islands in a most intensive and systematical way, \xe2\x80\x94 because I should not have been competent to critisize his results, if I had not had a material of at least the same value at my disposal.\nAs Baker very precisely localized his stations, I could collect a large series of topotypes of nearly all his new species and subspecies. This, in addition to his reproductions of the holotypes and paratypes, and the comparison of some of his paratypes in the Zoological Museum of Amsterdam, made a study of Baker\xe2\x80\x99s collection rather unnecessary.

Description: I propose in this part of my catalogue of the Solariidae to deal only with the genus Solarium s.s. and to reserve the remaining genera of this family for the next publication. For the division of the Solariidae in genera I followed Thiele\'s Handbuch der systematischen Weichtierkunde, also as far as concerns the names. Not only did I mention those species of which we possess specimens in the Leiden Museum, but, like in the former catalogues, I have included also, as far as possible, those species of which no material is present in our collections.\nThe list is composed on the same lines as my previous ones. Of all species of which we possess material a list is given of the specimens, stating: 1) the letter which indicates specimens from the same locality and collector (donor), as far as they are kept dry; in case of specimens preserved in spirit the number of the jar is given instead, 2) the number of specimens, 3) the locality, 4) the collector or donor. When the locality or collector (donor) is unknown, I have placed a question mark instead.\nA special word of thanks is due to Dr. W. Adam for his kind help, afforded during my stay in the Mus\xc3\xa9e Royal d\'Histoire Naturelle de Belgique at Brussels and to Mr. R. Winckworth who was so good as to copy for me a long description with many figures, which was not obtainable in the libraries in Holland or Belgium.\nMany names have been used by the authors for the different cingula (zonae, vittae, lirae) and sulci of the Solarium\'s and in some cases different authors have applied the same name to different cingula, what may be a cause of confusion. For the sake of clearness I have combined the principal terms in a list for a case where all sulci and cingula are present, as for

Description: This paper contains the results of the study of the fish-collection, made by P. Wagenaar Hummelinck, on the islands of the Leeward Group and some parts of the adjacent South-American continent, in 1936\xe2\x80\x94\xe2\x80\x9937 and in 1930. The latter have already been studied by Miss M. Sanders (1936) and are only included for completeness\xe2\x80\x99 sake.\nThe material has been presented to the Zoological Museum of Amsterdam.
