Eyton’s Whistling Duck. 
Dendrocygna vagans, Eyton’s MSS. 
Although a specimen in the Collection of the Zoological Society of London, and others in 
the British Museum, were marked by Mr. Eyton as distinct under the name of vagans, the species 
does not appear in his monograph of the family. The species is nearly allied to the Dendrocygna 
{Anas arcuata, Auct.), but differs in being larger, in having a decided black stripe down the back 
of the neck, and white tail-coverts. 
Habitat, Manilla, Philippine Islands. Specimens were in the Cumingian Collection; the 
specimen in the Society’s Collection is believed to have been presented by Hamilton Lindsay, 
Esq., Corr. Memb. 
The head, neck, and breast, pale brown, being darkest upon the crown of the head; the 
under surface of the body, pale chesnut; shoulders, deep chesnut; the back, wings, and tail, 
intense brown, approaching to black; the feathers on the back, broadly tipped with pale brown; 
down the back of the neck runs a black line, which extends from the occiput to near the insertion 
of the shoulders; the flank-feathers, are white, margined with blackish; under surface of the 
wings, blackish-brown. Bill and feet, black. 
Total length, twenty inches.
