migration into Ceylon is niucli more recent, geologically 

 speaking, than in the case of the Malabar-Kandyan con- 

 nexion. Mr. Wait discusses the geological and climatic 

 changes which appear to have been necessary to bring 

 about these results, and seeras to have made out a good 

 case for the ultimate firm establishment of his hypotheses. 



Austral Avian Record. 



[The Austral Avian Hecord. Vol. iii. Nos. 7, 8. Editor, Gregory M. 

 Malhews. Loudon : Dec. 1919, Feb. 1920.] 



The second of tiiese numbers contains only the Title Page, 

 Table of Contents, and Index to the third volume; but the 

 first consists of an account of the life and work of three 

 living Australian Ornithologists — S. A. White, T. Carter, 

 and W. D. K. Macgillivray. To the first, himself the son 

 o£ the well-known Zoologist of Gould's time, we owe the 

 greater part of our knowledge of the birds of Central 

 Australia, as well as much information concerning those 

 of the North ; the second is equally noted for his work in 

 the West, and has contributed several papers to ' The Ibis ' 

 from 1886 up to this year ; the third is of the same clan as 

 the noted author of the * History of British Birds,' and is 

 still as energetic as ever in the pursuit of science. All are 

 responsible for the discovery of new forms, or the re- 

 discovery of old ; and, what is almost more important in 

 Australia, have added immensely to our knowledge of the 

 life-histories of the rarer species. Their writings are such 

 as must be read, marked, learnt, and inwardly digested.

 collecting under permits, and a good paper by Mr. Fleming

 agreement with the editor. Moreover, Mr. Oberholser
