INTRODUCTION. . Xlli 



occurs, only a binomial name has been given, and the practice 

 now common of repeating the specific name has been avoided. 

 Thus in writing o the typical race of the Song-Thrush the 

 binomial Turdus musicus and not the cumbrous Turdus 

 mn$icns musicus is used, and it must be clearly understood 

 that, unless otherwise stated, Turdus musicus refers only 

 to the continental race of the Song-Thrush, and does not 

 include all the subspecific forms of the Song-Thrush as 

 a whole. 



In all cases where changes have been made in the specific 

 names used in the previous edition of the List, and also in 

 some cases where changes proposed by other writers have 

 not commended themselves to the Committee, an explanation 

 of the reasons for such a policy is given in Appendix III. 



REFERENCES. 



No attempt at synonymy has been made, but the earliest 

 references to specific and generic names have all been very 

 carefully checked. The other references given are to the 

 1st edition of the List, to the 2nd edition of Howard 

 Saunders' well-known ' Manual of British Birds/ and to the 

 * Catalogue of the Birds in the British Museum/ In cases 

 where additions have been made to the British List since 

 1899, when Saunders' ' Manual * was published, a reference 

 to the first definite British record is given. 



DERIVATION OF NAMES. 



The notes on the etymology of the generic and specific 

 names given in the old edition of the List were compiled 

 by Mr. H. T. "Wharton. In the new edition these have been 

 repeated and in some cases shortened. For this and for 

 the notes on additional names Mr. A. H. Evans is mainly 

 responsible.
