* All of the species of ducks here enumerated, except Marila marila, are repre- 

 sented in the Bureau of Science collection by specimens taken in the Philippine 

 Islands, but with the exception of the abundant Dendrocygna, arcuata these are 

 adults only, in winter plumage. I have constructed keys and diagnoses from this 

 material but for detailed descriptions I have depended almost entirely upon 

 Salvadori's monograph in volume 27 of the Catalogue of Birds in the British 

 Museum.
