liio author takes up his subject geographically in fifteen chapters, be- 

 ginning with Greenland and passing southward to Argentina and Chile, 

 discussing these in succession from the viewpoint of their biology and geo- 

 logical history, with special consideration of their faunistic affinities. It 

 would therefore have boon a great convenience to the reader if ho had given 

 a topical resume" of the evidence for the ton land bridges ho advocates dis- 

 connectedly in the course of the hook, summarising the pros and cons for 

 each in a connected way. defining also their presumed extent and con- 

 tinental connections, and their probable geological age and duration, 

 hornier supposed land areas and their connections offer a fascinating topic 

 for speculation, hut the evidence at present is s»i meager and conflicting 

 that the conclusions reached are apt to depend upon the temperamental 

 characteristics of the author. 



Or. Scharff has certainly presented us with a work of unusual interest. 

 and one which will stimulate to further investigation oi the problems he 

 has so elaborately discussed. J A \ 



Brabourne and Chubb: 'The Birds of South America.' 1 - -The 

 appearance of the first volume of this monumental work will he welcomed 

 by ornithologists the wot Id ovei Even though it be merely a list similai 

 in style to Shatpe's ' Band-List,' a framework as it were upon which the 

 main structure is to ho built up — it is nevertheless of the greatest assis- 

 tance to students of the neotropical avifauna, as the writer has already 

 had occasion to prove. It is forty years since Sclater and Salvin published 

 their ' Nomenelator Avium Neotropicalium ' and we have had no general 

 work on South American birds since. It is moreover a great advance over 

 Sharpe's ' Band-List ' since the references are given in full with type locali- 

 ties and the nomenclature has been made to conform largely with the In- 

 ternational Code, binomials are used, as the authors explain, merely as 

 a matter of convenience, the intention being to work out the relationship 

 o( species and subspecies and adopt trinomials in the body of tie work.
