PREFACE. Vll 



with which they have kept me supplied with reprints 

 of their writings. 



The abbreviations of the names of periodical pub- 

 lications and other literature used in the notes and 

 synonymy of this book are, as far as possible, those 

 of the Zoological Record ; but there are a few books 

 and papers which are so constantly referred to that 

 I have thought it best to adopt extremely short 

 abbreviations for them; a list of these with the full 

 title of each paper and where it may be found follows 

 this Preface. A bibliography, together with a list 

 of known foreign species and a full index, will be 

 given at the end of Vol. II.
