Description: For temperature investigations, a core in the Mediterranean Sea (No 189 of the Swedish Deep-Sea Expedition 1947-1948) was sampled at approximately 10 m intervals. Globigerina dubia, G. inflata and Globigerinoides rubra were seperated from each sample and their test were investigated for stable oxygen isotopic measurement. Oxygen isotopic analysis showed the following: 1) Ten stages are indicated. 2) The temperature minimum of stage 2 corresponds to a racliocarbon age of 17,200 years. 3) Temperature maxima of odd stages are about equal to the modern August mean, except that of stage 5 which is considerably higher and, probably reflects the influx of ice melt water. 4) Temperature minima of even stages are all very low, especially that of stage 2, and reflect conditions similar to those now prevailing around Newfoundland. 5) The temperature record indicates that during most of the time covered by the core, the Mediterranean was cooler than at present and that conditions similar to the present occurred only during comparatively short intervals. 6) Minor temperature fluctuations occur, especially in the warmer stages, which are of doubtful significance. 7) An average rate of sedimentation of 4.3 cm/1000 years is indicated for the whole core.

Description: Opinions are divided in relation to what generical name has priority, Heliacus or Torinia. In proof of this I will quote, leaving aside those of many others, the opinions of two authorities.\nThiele [1918, p. 80 (114)] writes: "Bez\xc3\xbcglich des Namens Torinia bemerkt Iredale, dass ihm Heliacus Orbigny, weil \xc3\xa4lter, vorzuziehen sei; es mag sein, dass dieser Name ein wenig \xc3\xa4lter ist \xe2\x80\x94 nach Hermannsen von 1841, nach Iredale 1842, es scheint also die Zeit des Erscheinens nicht ganz festzustehen \xe2\x80\x94, w\xc3\xa4hrend Torinia von Gray 1842 auf die Beschaffenheit des Deckels hin begr\xc3\xbcndet worden ist".\nThe opinion of Tomlin (1928, p. 333), however, is quite different: "Gray in Proc. Zool. Soc., 1847, \xce\xa1\xc2\xb7 151, gives his own genus Torinia precedence, quoting it as of 1840 and 1842. These two references are to different editions of the \'Synopsis of the Contents of the British Museum\', and are fully explained by Iredale in Proc. Malac. Soc. (London), X, pp. 294-309.\nThe 1840 usage of Torinia is a nomen nudum; the 1842 edition gives a short comparative account of operculum only, quoted on p. 308. It hardly seems a sufficient diagnosis on which to found a genus, and the reasons for rejection given by Iredale on p. 301 may well be applied to this case at any rate".\nAs I mentioned already in a previous paper (1940, p. 223), I follow in this catalogue Thiele\'s "Handbuch der systematischen Weichtierkunde", in relation to the generic names and also as far as concerns the classification, but it is not my intention to state thereby hat I always completely agree with the opinions of his author.\nI wish to express here my heartiest thanks to the gentlemen who helped

Description: Exbucklandia R. W. Brown ( Bucklandia R. Br. non Pr. ex Sternb., Symingtonia Steen.) In an article on \xe2\x80\x9cAlterations in some fossil and living floras\xe2\x80\x9d (J. Wash. Ac. Sc. 36: 348. Oct. 1946) R. W. Brown proposed the new generic name Exbucklandia for the Hamamelidaceous genus Bucklandia R. Br., non Pr. ex Sternb., while describing a new fossil species from the United States. He also transferred B. populnea to the new genus. Unfortunately I had overlooked this publication when proposing Symingtonia to replace Bucklandia R. Br. (Acta Bot. Neerl. 1: 443\xe2\x80\x94444. 1952). Exbucklandia will have to be accepted for it in future. The Indo-Chinese species B. tonkinensis Lecomte should be referred to as Exbucklandia tonkinensis (Lecomte) Steen. comb. nov. I have to thank Dr E. H. Walker for pointing my attention to R. W. Brown\xe2\x80\x99s paper.

Description: This charming and handy book printed on excellent paper, with its numerous clear pictures of well-known Malayan plants, reminds one in many ways of Merrill\xe2\x80\x99s \xe2\x80\x9cPlant Life of the Pacific World\xe2\x80\x9d (MacMillan 1946, New York), which has perhaps served Prof. Holttum as an example. Its size being only slightly smaller than Merrill\xe2\x80\x99s book and the area covered being very considerably smaller, its descriptions of plants are naturally more detailed; the more so as only a choice has been made, in which the special interests of the author \xe2\x80\x94 ferns, orchids, gingers \xe2\x80\x94 are evident though not predominant.\nThe plants described are not regionally arranged. The 17 chapters are rather headed by names of life-forms, striking organs, and special habitats. As is pointed out in the Preface, the book is \xe2\x80\x9cintended primarily for the Malayan resident who wishes to begin a study of Malayan plants\xe2\x80\x9d. In this purpose the book will doubtless prove to be a success: the reader is gradually taught quite a bit of botany of various fields, morphology, anatomy, ecology, hybridisation, etc. These are demonstrated at plants which are within easy reach of the ordinary layman for which it is destined. Short opening and concluding chapters deal with general features of tropical plants and with the Malayan forest. Since the author is a well-known expert and the Malayan flora as here described is a very good example of any flora between, say, Calcutta and Fiji, it may well be useful to residents of many other countries as well.

Description: A study has been made of the Indo-Malaysian species of Cnestis. The mutual length ratio of sepals and petals, \xe2\x80\x94 brevi- and aequipetaly \xe2\x80\x94, is the main differentiating character for the species; there are no transitions. The areas of distribution overlap in the Malay Peninsula (fig. 1); brevipetalous types are known from the Malay Peninsula, Sumatra, Borneo and Celebes, aequipetalous types from Burma, Siam, Indo-China and the Andaman Islands, the Malay Peninsula and the Philippines. Fruits are of two different shapes: beaked in aequipetalae of the Andamans, Burma, Siam, and Indo-China, pear-shaped in remaining aequipetalae and in brevipetalae. Leaves tend to be longer and jugae more numerous in brevipetalae than in aequipetalae.\nOther characters do not have so clear a separating value, such as texture and indumentum of leaflets, indumentum of inflorescence, texture and indumentum of petals, length of stamens, type and length of pistils, length ratio of stamens and pistils. However, even on the strength of these characters there is some reason to distinguish both groups mentioned above. As to the indumentum of petals there is a remarkable cline in a decreasing sense from the Philippines to continental Asia, the Andamans and the Malay Peninsula and back to the east through the brevipetalae of Malay Peninsula, Sumatra, Borneo and Celebes.\nBrevi- and aequipetalae have been considered to represent two species, viz Cnestis platantha Griff. and Cnestis palala (Lour.) Merrill. The latter one has been divided into two subspecies, viz subsp. palala with beaked fruits and subsp. diffusa (Blanco) Andreas with pear-shaped fruits. For their area of distribution see fig. 1.\nIn many respects some plants of the Andamans, Burma, Siam, Indo-China (and the Malay Peninsula) are different from the remaining aequipetalae, but not in a uniform way as to the various characters. Although there are some arguments for a further taxonomic subdivision, we did not think it advisable to introduce such a division at present. Our classification differs from the division as given by Schellenberg (1938). This was caused by the material on one hand, being more heterogeneous than Schellenberg described it, and, on the other hand, by the fact that some of the diagnostic characters used by him, in our opinion were not fit for use as such. Therefore a revision of Schellenberg\xe2\x80\x99s system of the genus Cnestis seems desirable.

Description: In Madro\xc3\xb1o (1936) Herre has lamented the disappearance of lichen species through the disastrous interference of man. Unavoidably, the advance of civilised modern life is linked with destruction of the vegetation. This applies all the more as the endangered area is more densely populated and it certainly applies most alarmingly to the lichen flora of the Netherlands. Here, every way-side tree felled is an irreparable loss to the epiphytic lichen communities, every acre of heath burnt or turned into arable land is a blow to our stock of terrestrial lichen species, whereas the use of dry fertilisers and the spraying of orchards are very effective in killing any lichen in the neighbourhood that otherwise might have survived. A comparison of the material preserved in the older collections with what can be found nowadays, clearly shows what has gone lost. It is sad to think that an ever increasing number of species are on their way to total extermination.\nHowever, from a thorough investigation of the epiphytic communities of cryptogams latterly started by Mr J. J. Barkman, it becomes apparent that at least to some extent the losses may be compensated by the discovery of species hitherto overlooked or not recognised. It is on such and other finds that I intend to report from time to time.
