iv Preface. 



The Translators desire to express their thanks to Mr. W- 

 E. Hoyle for suggesting that they should undertake the work, 

 and also for his valuable help throughout, especially for his 

 kindness in looking over many proof-sheets : to Prof. Newton, 

 for kind assistance with terms relating to the migrations of 

 Birds: to Prof. E. B. Poulton, Mr. Barclay Thompson, and 

 Dr. W. B. Benham, for many helpful suggestions. Finally, 

 they desire to express their indebtedness to the Eadcliffe 

 Library, where they have not only had complete access to 

 recent Zoological literature, but also every assistance in tracing 

 references and in procuring records for the faunistic sections.
