It appears, therefore, that the British Museum Collection contains 

 specimens of the eggs of about one-third of the total number of the 

 living or recently-extinct birds belonging to the above mentioned 

 Orders, as enumerated in the ' Hand-list.' 



With few exceptions, the eggs now illustrated have not been 

 figured before. It only remains to add that the measurements of 

 the specimens throughout this Catalogue are invariably in English 

 inches. 



The symbols 'employed in the present volume are the same as 

 those in the ' Catalogue of Birds.' [P.] means " Presented by," 

 [C] " Collected by," [E.] " Received in exchange."
