XXVI PREFACE. 



lightened by the admirable and systematic Bibliography 

 for the Northern Counties, published in the present 

 series of TJie Naturalist. The species added to the 

 Lancashire list in this edition are the Purple Heron 

 (p. 145), Sociable Plover (p. 213, with woodcut), White- 

 faced Petrel (p. 258), Wilson's Petrel (p. 258), and 

 Black-necked Grebe (p. 262). There is a new Index. 

 Inasmuch as the full-page illustrations of Duck-decoys 

 in the first edition relate to Fritton in Suffolk, and 

 have, moreover, already appeared elsewhere, they are 

 now omitted.
