| Van Kampen (1924, p. 284) mentions only two species of frogs from Morotai Island; the identification of one of these was considered to be doubtful. Of snakes De Jong (1928, p. 149) records five species from this island. The study of a small collection of frogs and snakes from Morotai, presented to the Leiden Museum in 1862 by H. A. Bernstein, and of two frogs collected by Prof. H. J. Lam in 1926, allows of some additions to be made to previous lists. The species not mentioned by either Van Kampen or De Jong are indicated by an asterisk. * Hyla infrafrenata Gthr. 4 specimens, Morotai, leg. H. A. Bernstein, 1862, reg. no. 1833. * Hyla rueppelli Bttgr. 2 ♂ ♂, between Bilowoh and Goegoeti, Morotai, VI. 1926, leg. Prof. H. J. Lam. These two specimens show some... |

| Accessibility of the Buitenzorg Herbarium. – In Blumea 6, p. 307 (1948), bottom of the page, it is mentioned that the Buitenzorg Herbarium is ”as yet inaccessible”. The author wrote this article apparently under war-time conditions and neglected to omit this statement which is now obsolete. In order to avoid confusion it may be announced that the Buitenzorg Herbarium is, since January 1947 in full running condition: Head is Dr D.F. van Slooten, botanists present are Dr M.A. Donk, Dr S. Blaembergen, A.G.L. Adelbert, and Dr J. Zaneveld. Of the Bulletin parts 3 and 4 of volume 17 have appeared resp. in Dec. 1947 and May 1948; the first number of vol. 18 is in the press. Duplicates and loans are dispatched, and exchange of collections is resumed. Flora of... |

| The smaller islands of the Caribbean Sea support relatively few species of ants. Even in the largest island in the West Indies, Cuba, there were in 1934 only about 90 forms (species, subspecies and „varieties”) known and this number has not been greatly increased since. During the 1930’s there were recorded in the entire West Indies some 450 forms and at the present time the number can hardly much exceed 500. By way of comparison, the most recent enumeration of ants of the United States (1947) shows 742 kinds. The larger proportion of these West Indian ants occur on such islands as Hispaniola which offer varied and stable habitats. The small islands have relatively few species and these are in the large part common tropicopolitan forms which tend to drive... |

| Whilst visiting the Leeward Group, in 1936—1937, I couldn’t help being fascinated by the striking occurrence of representatives of the arachnid order Chelonethida on every island of this arid region which invited me to an investigation of its soil fauna. This first publication of a serial on a group in which so much taxonomical work has still to be done, may be considered as the inevitable aftereffect of these first-sight impressions. My grateful thanks to JOSEPH C. CHAMBERLIN (Forest Grove, Oregon) and C. CLAYTON HOFF (Fort Collins, Colorado) for their interest in my work and to WILLIS J. GERTSCH and E. BROWNING for letting me have the loa.n of some material deposited in The American Museum of Natural History and the British Museum (Natural History). |

| It is a great pleasure to announce that the technical difficulties delaying the printing of Flora Malesiana have now been overcome. The first part of volume 4 is in the press and, in all probability, will appear towards the end of this year. Sample sheets of volumes 1, 2, and 3 will be added to the initial instalment of volume 4. Owing to a generous grant by the Netherlands Indies Government of this first issue of the 4th vol. 2500 copies will be printed and distributed to all individual botanists and institutions which are believed to have an interest in the Flora, in order to enable them to form an idea of the scope, execution, and costs of subscription of the work. Those receiving this Bulletin will also receive the initial part. It is expected that... |

| It seemed useful to correct some errors which have crept into the text of volume 4 as well as to add some additional data which came to our knowledge and are worth recording. Valuable help in general was rendered by Dr R. C. BAKHUIZEN VAN DEN BRINK Jr, for additions to the Burmanniaceae by Dr F. P. JONKER, for Chenopodiaceae by Dr C. A. BACKER, for Viburnum by Mr J. H. KERN, for Xyris by Dr P. VAN ROYEN, and for a grass by Dr P. JANSEN. Printing errors have only been corrected if they may give rise to confusion. The page numbers a and b denote respectively the left and right column. |

| INTRODUCTION The Blattid fauna of the Malayan subregion is very rich, accordingly since the earliest period of orthopterology students of Blattids have described and mentioned specimens from this region. Consequently the literature on Malayan Blattidae is greatly scattered, and though some of the authors did a considerable amount of work in compiling the most important contributions on the present subject, there is still much to be done in unravelling synonymy and distinguishing generic units and subfamilies. Brunner (1865) already described a great number of Malayan Blattidae. The descriptions of new species by Walker (1868, 1869 and 1871) are very vague and full of mistakes, giving rise to a great deal of confusion. Shelford largely restored the... |
