VI PREFACE. 



Islands, has been carefully arranged for exhibition in the Pavilion 

 of the Bird-Gallery, and has proved of great assistance to students 

 of the eggs of our native species of birds. 



It is to be regretted that the whole of the first volume of this 

 Catalogue was printed before the valuable bequest of eggs by the 

 late Mr. Philip Crowley could be incorporated ; but in the future 

 volumes of the Catalogue the collection bequeathed by Mr. Crowley 

 to the nation, one of the most valuable of the donations of recent 

 years, will be duly chronicled. 



I have to acknowledge much assistance in editing the present 

 volume from Dr. Bowdler Sharpe, the Assistant Keeper in charge of 

 the Sub-Department of Vertebrata.
