322 duck. 



feathers at the back of the head, and a little way down the neck, 

 long and crested ; forehead and crown dull ferruginous; near the 

 base of the bill, in the middle, a white spot; round the eyes, hind- 

 head, and crest, shining green, glossed with copper, especially on the 

 temples; chin white; beneath this are two collars, the first greenish 

 black, springing from the crest ; the lower one white ; the rest of the 

 neck and breast cinereous, undulated with brown ; back grey, the 

 upper part obscurely lineated with a paler colour ; belly dotted grey 

 and white ; vent black, the sides of it white, divided transversely by 

 a black band ; shoulders grey, and somewhat undulated ; scapulars 

 grey, and curve inwards at the ends; speculum fine blue green, 

 above it a white band ; wings and tail equal in length ; legs 

 lead-colour. 



Inhabits the east part of Siberia, from the River Jenisei to the 

 Lena, and beyond Lake Baikal, but not in the West ; found also at 

 Kamtschatka, but rarely ; probably winters in the Mongolian 

 Deserts, and in China, but assuredly found in the last, as a speci- 

 men, brought alive from thence, lived for some time among other 

 poultry in England, became tolerably familiar, and when it died was 

 added to my collection.

This differs in having the head very little crested on the crown ; 

 no falciform feathers falling over the wings ; no white on the vent, 

 or sides of it ; instead of which they, as well as the back, are brown ; 

 and the thighs white ; in other things it much resembles the former, 

 and we suspect it to be the female, or young bird, of this beautiful 

 species. I have also observed one very similar among some Chinese 

 drawings ; and as this last is said to be found at Java, it is probably 

 no stranger to India likewise.*
