* 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.
