 ON A NEW DUCK FROM THE ISLAND OF SUMBA 



BY 



Dr. J. BÜTTIKOFER. 



Amougst a number of unregistered bird-skins in our 

 Museum , which passed through my hands a few weeks 

 ago, I found a Duck from the Island of Sumba with very 

 worn plumage and damaged feet, probably a female or an 

 immature male, which I was unable to identify with any 

 known species. Count Salvadori, to whom I sent the bird 

 for comparison , kindly wrote me that the bird certainly 

 belongs to a new species, but that it is rather difficult 

 to find the right place for it in the system , unless we can 

 dispose of an adult male. 



For this reason I do not wish, for the present, to give 

 the bird a definitive generic name , and consequently propose 

 to name it, in honour of Count Salvadori, the author of 

 the recent excellent monograph of the Anseres in the Ca- 

 talogue of Birds in the British Museum 



Anas Sal V ad or ii. 



Crown and occiput uniform brownish black , glossed with 

 purplish , but yielding somewhat to metallic green under 

 a certain light; a rather narrow stripe along the hind- 

 neck, and whole upper surface of the body with the 

 inclusion of the scapulars , glossy purplish brown , the 

 feathers on the mantle with a bronzy brown gloss on the 

 terminal edge, giving this part a wavy appearance under
