Description: Among some coccids from Indonesia, received from Dr. L. G. E. KALSHOVEN, four large specimens were found which by their well developed ovisac showed some resemblance to Icerya purchasi MASK. After comparing the specimens with the photographs in MORRISON\xe2\x80\x99S Classification of the Margarodidae (1928) it appeared, however, that the wax covering of the body was more alike that of Walkeriana floriger (WALKER).\nThe old pinned specimens were not labelled, but Dr. KALSHOVEN remembered that they had been collected by Prof. ROEPKE on \xe2\x80\x9etjemara\xe2\x80\x9d (Casuarina). Upon inquiry Prof. ROEPKE informed me that in 1910 he had collected a giant coccid on old stems of Casuarina Junghuhniana MIQ. in the Tengger Mts. (East-Java). The specimens were found on trees near the last bend of the road leading to Tosari, a well-known health-resort at an elevation of about 1750 m, where Europeans often used to spend their holidays. Some specimens had been sent to Mr. E. E. GREEN in Ceylon who replied that it was a species of Walkeriana, but that he wanted the larvae for a description of this new species.

Description: In May 1938 I had the opportunity to observe seven living Aplysia depilans in the Zoological Station Naples. Notes on the size and colour were made and different methods of preservation were tried.\nAs one often wonders how much of the original colour pattern has been preserved in museum specimens of Aplysia, it seems important to give the result of the comparison of the living specimens as studied in 1938 and the same specimens after 18 years of preservation, in 1956. The best way of preservation appears to be killing in diluted alcohol as specimen nr. V shows.

Description: The results of a complete census of the breeding population of the White Stork (Ciconia ciconia) in the Netherlands, carried out in the year 1950 by the State Forestry Service, have been published by M\xc3\x96RZER BRUIJNS and BRAAKSMA in Beaufortia 5, Nr. 45, April 15, 1955, p. 23\xe2\x80\x9442.\nA new census was performed during the year 1955 ; it is the intention to repeat the census from now on every year.\nThe results of the last census are even more alarming than those from 1950 (see table, p. 113). The number of occupied nests decreased from 83 nests in 1950 to 58 nests in 1955. The number of fledged young decreased from 195 in 1950 to 96 in 1955. Many nests, still occupied in 1950, were either in a state that they could no longer be used or they had vanished altogether in 1955. On the other hand some new nests have been erected in recent time, some of them yielding good breeding results. The data have been arranged in tables according to the provinces. Every nest is numbered. The numbers of the 1950 census are given in parentheses. Nests marked + means that the nest was occupied by a pair of birds, but that no young were fledged. Nests marked \xe2\x80\x94 means that the nest was not inhabited, or that it was visited irregularly or else occupied by one solitary bird. The number of young fledged is marked by a figure. A gale in the spring of 1955 destroyed 4 nests ; 12 eggs got lost.\nFighting was reported frequently, the unfortunate result being that 3 young storks and at least 37 eggs got lost. These figures probably indicate that at present an insufficient number of nesting sites is avaible in the Netherlands. Therefore it seems worth while to try to erect new nests in localities where fighting has been frequently reported, and to repair those nests that have been visited, but remained unoccupied, owing to the poor state of the nest. In this connection Mr. W. DRIESSEN got most remarkable results with a newly erected nest, made according to a special method. This method should be used for the nests which we hope can be erected or repaired before the new breeding season. Surely the alarming decrease of the White Stork in the Netherlands is not primarily caused by housing problems, but a more appropriate condition and a greater number of nesting sites probably helps to prevent the yearly destruction of perhaps ten or twenty eggs or chicks.\nPhotomechanical reproduction

Description: 1. In einem kleinen Material aus der Uferzone des Ohrid-See wurden 16 Arten freilebender S\xc3\xbcsswassernematoden aufgefunden ; es werden systematische Bemerkungen zu einigen Arten gemacht. Neochromadora trilineata W. SCHNEIDER, 1943 wird mit Punctodora ohridensis W. SCHNEIDER, 1943 identifiziert, die Gattung Hofmaenneria W. SCHNEIDER, 1940 wird diskutiert und es wird ein Beitrag zur Synonymie von Theristus dubius-setosus (B\xc3\x9cTSCHLI) geliefert. 2. Von den gefundenen Arten wurden 10 schon 1943 von W. SCHNEIDER aus dem Ohrid-See bekannt gemacht. Die f\xc3\xbcr den Ohrid-See neuen Arten sind : Tripyla filicaudata, Dorylaimus intermedius. Chromadorina bioculata, Ethmolaimus pratensis. Paraplectonema pedunculatum, maenneria brachystoma. 3. Der Anteil endemischer Formen an der Nematodenfauna des Ohrid-Sees ist gering. Abgesehen von Ohridia bathybia SCHNEIDER, 1943, deren Verwandtschaft und systematische Stellung unklar sind, ist allein Punctodora ohridensis W. SCHNEIDER, 1943 eine Art, die bisher ausserhalb des Ohrid-Sees nicht beobachtet worden ist.\nEs sind aus dem Ohrid-See keine Nematoden-Arten bekannt, die als marine Relikte angesprochen werden k\xc3\xb6nnten.

Description: The result is given of a complete census of the breeding population of the White Stork (Ciconia ciconia) in the Netherlands, performed during the year 1956. The results of the census of 1950 and 1955 have been published in Beaufortia 5 (45), April 15, 1955: 23\xe2\x80\x9442, and 5 (52), March 24, 1956: 101\xe2\x80\x94115.\nThe result of the census 1956 shows a less alarming picture than that of 1955. The number of nests occupied by pairs increased to 65 (57 in 1955)\xc2\xb9). The number of young fledged increased to 95 (94). However, three newly fledged young perished in the neighbourhood of their nests, so that the ultimate breeding result of the species in 1956 is somewhat less than in 1955. The number of nests on which breeding occurred was higher than in 1955. From 65 (57) nests occupied by a pair of birds breeding occurred in 44 (36) cases. The very unfavourable weather might have influenced the relatively bad results. The storks arrived considerably later than in other years.\nNevertheless the sharp decrease which could be observed after 1950 seems to have come to a stop. The White Stork in the Netherlands lives at the border of its breeding area and population fluctuations have to be considered in this connection as far as even expecting the vanishing of the species from the Netherlands fauna at all. Everything is done at present to prevent the loss of the White Stork from this country. The Netherlands Society for the Protection of Birds has started an action for erecting new nesting sites. Well-known investigations in Bavaria have shown the density of the population to increase by this way. It has yielded some results in the Netherlands too. Six new nests have been occupied by pairs or solitary birds and on two of these nests young have been raised of which 7 fledged. In the present paper all nests are renumbered and the numbers of the 1950 census are given in parentheses. Where this number is failing the nest has been occupied after 1950 or 1955. Nests marked by + were occupied by a pair of birds but no young birds were raised. The number of young storks fledged is indicated by a figure. A summary of the results and a comparison with 1950 and 1955 is given in the tables 9, 10, and 11. The number of eggs and young storks which got lost by fighting on the nests and the number of nesting sites lost since 1950 are given on page 192.

Description: Anticipating a revision of the genera and subgenera of the tribe Anthophorini, a number of south-east Asiatic species previously included in Anthophora Latreille, are transferred by the author to Amegilla Friese. The types were studied of Anthophora villosula F. Smith, and of 19 valid and 3 invalid species of Amegilla (i.e., of all species discussed, except that of himalajensis Radoszkowski), and a key to their identification is included. The following new species are described: A. proboscidea, \xe2\x99\x80 (Simalur I.), sumatrana, \xe2\x99\x82\xe2\x99\x80 (Sumatra), pagdeni, \xe2\x99\x82 \xe2\x99\x80 (Malaya), and leptocoma, \xe2\x99\x82 \xe2\x99\x80 (Siam & Malaya). Re-descriptions of both sexes and figures are given of A. insularis (F. Smith), himalajensis (Radoszkowski), florea (F. Smith), and urens (Cockerell). Apart from the specific descriptions, notes and records are provided concerning geographical distribution, new localities, and the identity of plants visited. The following cases of synonymy are established : A. fulvohirta Meade-Waldo, 1914 (= insularis F. Smith, 1858) A. proserpina Gribodo, 1893 (= himalajensis Radoszkowski, 1882) A. pahangensis Meade-Waldo, 1914 (= himalajensis Radoszkowski, 1882) A. pahangensis Cockerell, 1927 (= pendleburyi Cockerell, 1929) A. anthreptes Lieftinck, 1944 (= pendleburyi Cockerell, 1929) Anthophora villosula auct, nec F. Smith, 1854 (= Amegilla spec. diff.) Anthophora soror J. P\xc3\xa9rez, 1905 (= Anthophora villosula F. Smith, 1854) Anthophora pingshiangensis Strand, 1913 (= Anthophora villosula F. Smith, 1854)

Description: The only record of Thesium in Malaysia was hitherto the Southern Chinese Thesium psilotoides Hance from medium altitudes of the Benguet and Bontoe Mountain Provinces in North Luzon, according to Merrill (Enum. Philip. Fl. Pl. 2, 1923, 115), occurring between 1200 and 1500 m. The same species has also been found in the Lesser Sunda Islands, Sumba Island, by C. N. A. de Voogd (E. Sumba, 300 m, limestone quarry, De Voogd 1873 (80, L), Dec. 1, 1934, plant pale green, fruit yellow, flower white).\nThe Sumba specimens exactly match the Philippine specimens. Species like this one, with a very short calyx tube, look astonishingly like Halorrhagis, in habit, but possess 5-merous flowers, lack bulbous-based hairs, and show a peculiarly cartilaginous leaf apex.

Description: These fascicles, the first part of a moss flora of Fennoscandia, comprise five (acrocarpous) orders of the Eubryales. All species and a number of forms and varieties have been included. There are clear dichotomous keys to genera and species. Of each species the original literature, the most familiar synonyms, an excellent description with critical remarks on the differences between allied species and original drawings have been given. Ecology and general distribution have been indicated, with special reference to Scandinavia. In addition there is a glossary of technical terms, which is nearly identical to that in Dixon\xe2\x80\x99s famous Student\xe2\x80\x99s Handbook of British Mosses, though less extensive.\nNevertheless it may be doubted whether this book actually fills a need in Scandinavian bryology. It is not suited for \xe2\x80\x9cworkers in all fields of botany, forestry, limnology, etc.\xe2\x80\x9d, as the author suggests, since keys to the families are lacking. Besides, there is the excellent moss flora of Brotherus, Die Laubmoose Fennoscandias, not mentioned in this connection in the preface.
