 with their avicultural liistory. Finally, we must mention 

 a contribution from Sir William Ingram containing the 

 diary of the caretaker employed by him to look after the 

 Great Birds of Paradise on the island of Little Tobago 

 in the West Indies. Sir William believes that these birds, 

 introduced by him eight or nine years ago, have now 

 become completely acclimatized and are increasing by 

 natural means.

 Union. Vol. xvi. July 1916-April loi?.] 



Some of the numbers of our Australian contemporary 

 have not reached us so punctually or regularly as usual. 

 They have suffered perhaps from "enemy action" ; hence 

 the delay in noticing the last completed volume, which is 

 edited by Messrs. J. A. Leach and C. H. CroU ; Mr. C. 

 Barrett, whose name appears only on the first number as 

 joint-editor, has joined the Australian Expeditionary Force. 

 We wish him good luck and a safe return. 



Perhaps the longest and most important paper in the 

 present volume is one in which Mr. H. L. White gives an 

 account of an expedition organized by him and undertaken 

 by Mr. William M'Lennan along the northern coast of 

 Australia. Leaving Thursday Island in his cutter 'Avis' 

 on 29 June, 1915, Mr. M'Lennan coasted along the Gulf 

 of Carpentaria and beyond, nearly as far as Port Essington. 

 He landed at many places and collected birds and eggs, and 

 explored a vast heronry situated at the mouth of the Roper 

 river, never before visited by an ornithologist. Mr, M'Lennan 

 did not get back to Thursday Island till May 1916, and was 

 then suffering from a very severe attack of fever and beri- 

 beri. Two papers deal with the expedition, one containing 

 M'Lennan's journal illustrated with a map, the other a list 

 of the species obtained. 



Among other faunal papers are two by Mr. W. B. 

 Alexander on birds noticed at Bremer Bay on the soutliern
