| The following notes on new synonymy of the species of South Asiatic Microlepidoptera of the families Tortricidae, Phaloniidae, Eucosmidae and Glyphipterygidae were made during a visit to the British Museum, Natural History, London, in 1946 and chiefly concern the material in the extensive collection of the late E. MEYRICK. A few additional new synonyms of Eucosmidae and of Carposinidae are not included and will be dealt with in another place. We are greatly obliged to the Trustees of the British Museum for the opportunity to study these collections, and also to Mr. W. H. T. TAMS, of the Division of Lepidoptera of that Museum, for his kind help and suggestions. |

| Our knowledge concerning the periodical movements in animals called migrations is chiefly based on observations on birds. By and by, however, a number of facts concerning migration in other animal groups have been assembled and it seems worth while to compare them with those known for birds. There is the more reason to do so here, because the victim of this jubilee is interested in birds and fishes alike. Though I shall not restrict myself to these two groups they will take more place than the rest. In the following I shall deal with North to South and South to North migrations chiefly. In the hope to succeed and make my ideas comprehensible to those who are not specially acquainted with this particular field I shall begin with a very short description of... |

| In the former Zuiderzee, the large brackish inland sea of the Netherlands, a species of crab was commonly met with, which species generally was considered to be endemic in the Dutch inland waters, and was named by most authors Heteropanope tridentata (Maitland). Examination of material and literature convinced us that the crab does not belong to the genus Heteropanope at all, but is a Rithropanopeus, while it is so closely related to the American Rithropanopeus harrisii (Gould), that we only can consider it to be a subspecies of that species. The synonymy of the Dutch form is as follows: Pilumnus tridentatus Maitland, 1874, Tijdschr. Nederl. dierk. Ver., vol. 1, p. 232. non Pilumnus tridentatus Maitland, 1876, Tijdschr. Nederl. dierk. Ver., vol. 2, p. 11.... |

| The rich material of Copepods collected by the Snellius Expedition in the seas of the Eastern part of the Malay Archipelago was placed at my disposal in 1943 by Prof. Dr. H. Boschma. The material proved to be very interesting and contained, besides new species, many rare forms found for the first time in the Indo-pacific area. A report on the families Calanidae, Eucalanidae, Paracalanidae, and Pseudocalanidae will be published in Temminckia, vol. VIII, pp. 1-181. A report on the family Aetideidae was completed in 1946 but, as the printing difficulties created by the war have not yet sufficiently improved to warrant the publication of this report within a short time, it seems desirable to publish a preliminary account of some new or interesting forms.... |

| 1. The caterpillars of Philudoria potatoria. L. belong in Holland to two phaenotypes, a light one with a pale bluish-grey ground colour, strongly mottled with pale markings (figured in SEPP 1), and a dark one, which is nearly blackish blue and much less provided with pale markings (figured in practically all text books). 2. The pale caterpillars are confined to reedbeds in the lower western part of the country, the dark caterpillars principally to coarse grasses (e. g. Dactylis) in the higher parts (east and south). Mixed colonies are also known. See map. 3. It is highly probable that the colour forms of the caterpillars are due to environmental factors. From 37 light caterpillars collected in one colony in 1948 about half of them turned to dark ones in... |

| In Juni 1947 werden door mij in enige plasjes in de bosaanplant aan de Z.O.-kant van het eiland, in slootjes tussen de diverse bospercelen en in enige watertjes aan de Westkant (geen eendenkooien!) monsters genomen en wel op de volgende plaatsen: i. Ijsbaan achter het dorp Oostvlieland, 10 VI 2. Plasje in het bos, ten Z. van het schelpenpad langs de Weekend-huisjes, 10 VI 3. Visvijvertje, vlak bij vorig plasje, 10 VI 4- Plasjes bij Vliehors, ten Z. van de grote weg-, li VI 5. Plasje ten Z. van de grote weg iets meer naar Bomenland, 11 VI 6. Gat gevuld met water in hei achter Bomenland, 11 VI 7. Slootje langs het fietspad naar Vianen, Z-kant, 11 VI 8. Vijvertje bij bank V.V.V. in buurt van Vuurtoren, 13 VI 9. Idem 10.

| Prospects for an Indonesian Agar-agar Industry. – An Indonesian agar-agar industry seems possible. Seaweeds containing a sufficient percentage of agar-agar to make them eligible for industrial purposes, are found in suitable quantities in Indonesian waters. Dr J. S. Zaneveld, the recently arrived algologist of the Buitenzorg Herbarium (cf. p. 85), is at present at Batavia occupied in collecting scientific and practical data in view of a future industrial development of these natural resources. Dr Ch.J. Bernard, is Chairman of the new established Union Internationale pour la Protection de la Nature residing at Brussels, Rue Montoyer, 42. We are sure that the fast disappearing autochthonous fauna and vegetation of Indonesia will receive all possible attention. |

| Before the outbreak of the war with Japan the author had the intention to publish an extensive account on the occurrence of an aestuarine fishfauna in and in front of the large aestuarines and river-mouths so often found in India, Burma, Malaya, Thailand and Indo China and in the Greater Sunda Islands, Sumatra and Borneo, the rivers of the latter two islands being the special field of investigation. However as a consequence of the war all, thus far, unpublished notes and the greater part of the collections were lost as is the case with a most interesting sample of an aestuarine fishfauna from South New Guinea, where biologically the same conditions exist as in Sumatran and Bornean rivermouths. This last collection remained partly unpacked when war broke... |

| Hoewel ik in het voorjaar van 1948 slechts korte tijd op Curaçao en Bonaire verbleef, deed ik hier naast waarnemingen, die een bevestiging zijn van die van RUTTEN (1931), ook een aantal aanvullende observaties. Ik wil deze gaarne publiceren in de feestbundel ter ere van Prof. Dr. J. E. W. IHLE en Prof. Dr. L. F. DE BEAUFORT, met wie ik gedurende vele jaren op verschillend gebied zo aangenaam samengewerkt heb. Over de vogels der Benedenwindse Eilanden is nog slechts weinig geschreven. Eigenlijk bestaat er slechts één goed artikel en wel dat van RUTTEN (1931), die hierin niet alleen oude mededelingen van HARTERT en van CORY verwerkte, maar ook tal van nieuwe, eigen waarnemingen, deels van veldornithologische aard, mededeelde. De lijst van DE JONG (1948) is... |

| The financial year which ended 30th June, 1947, was the fourth year in which a group of selected wheat growers kept complete records of their financial transactions in co-operation with, and in Record Books provided by, the Division of Marketing and Agricultural Economics. Reports covering the records kept in 1944-45 and 1945-46 have already been published in this "Review". The notes which follow deal primarily with the financial position of the fifteen farmers who kept records during 1946-47. However, some comparisons with earlier years are made. |
