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. |

Le Castor du Rhône ( Castor fiber L.) a été particulièrement bien étudié par de nombreux auteurs. VICTOR PIRAUD ¹) a donné d’intéressants renseignements sur ses moeurs; M. P. CORDIER ²) et A. HUGUES ³) ont fait aussi une étude appronfondie de cet animal et L. GERMAND 4) a fourni une description détaillée des colonies de Castors de la région Avignonaise. Autrefois très abondant en France où il habitait la plupart des rivières, le Castor n’existe plus actuellement que sur le Rhône, certains de ses affluents et en Camargue. Grâce aux mesures énergiques de protection dont il est l’objet depuis un certain nombre d’années, il s’est multiplié et actuellement le nombre de ces colonies ne fait que s’accroître. Les stations les plus réputées sont les suivantes: |

Uma nova variedade de Coffea arabica L., provavelmente originária de Manhumirim, Estado de Minas Gerais, e cultivada em pequena escala no Estado do Espírito Santo, foi recebida, pelo Instituto Agronômico de Campinas, em 1937. Trata-se da variedade caturra. Carateriza-se por apresentar porte menor do que o da variedade bourbon, da qual provàvelmente se originou. Os internódios são bem curtos, tanto no caule como nos ramos, sendo intensa a ramificação secundária e de ordem inferior. As fôlhas são de um verde bem escuro, maiores e proporcionalmente mais largas do que as do Bourbon. As flores são pouco menores e os frutos e sementes um pouco maiores do que as dessa variedade. No presente trabalho apresentam-se os resultados das pesquisas taxonômicas relativas... |

It is notorious that the lycaon, the negro evil of plains, while by no means a declining race in Africa, has always been rare in Zoological Gardens. The reasons of this are twofold and closely interrelated. The animal presented some difficulties to rearing, readily perished and withal was not subject to reproduction in captivity and so there were no new born animals available for exchange between Zoological Gardens. Causes for the non resistance of lycaons under conditions of Europe are to be found less in climate differences between Europe and Africa — for the habitat of these plain animals to the South reaches far beyond the tropic of Capricorn — and so lycaons should not be excessively susceptibLe to the European climate and especially to temperature... |

The present paper is based mainly on material collected at the Canary Islands during the spring of 1947 by Dr. G. Thorson of Universitetets Zoologiske Museum at Copenhagen and Dr. C. O. van Regteren Altena of the Rijksmuseum van Natuurlijke Historie at Leiden. Most of the specimens were collected by Dr. Thorson, who devoted almost all of his time to the study of the litoral fauna, while Dr. Van Regteren Altena studied the inland fauna and only made occasional visits to the sea shore. The shrimp fauna of the Canary Islands is very poorly known. In 1839 Erulle, in the large work of Webb and Berthelot on the Natural History of the Canary Islands, listed 5 species of Caridea and since that time just two more species have been added to the list. The material... |

Recently RIPLEY (1941) has prepared a systematic revision of the Indo-Australian members of the genus Coracina (Cuckoo-Shrike), which for a considerable time had been in a state of great confusion. RYPLEY’s new arrangement represents a noteworthy step in the appreciation of the systematics of this difficult genus. Since only taxonomy and representative distribution have been taken into account by RIPLEY, resulting in the arrangement of 12 species into 3 superspecies and 7 isolated forms, certain problems still remain unsettled. It is the purpose of this paper to deal with some of these problems and to propose an arrangement of the Indo-Australian forms of Coracina not only in accordance with their taxonomy, but also with the history of their distribution.... |

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... |
