This Goose is not represented in the collections made by 

 me, but there is a male as well as a female in the collection 

 of Miss Runnacles, taken on the 29th of June, 1909, at 

 Los Ynglases, Ajo. 



The female is adult and is moulting, except the wings and 

 tail, the old feathers shewing much signs of wear. 



The male is a young bird moulting, except for the wings 

 and tail, into the adult dress. The old feathers on the 

 chest and back are all the barred feathers of the young- 

 bird ; the wing lacks the glossy speculum, and a few barred 

 feathers remain on the breast. 



The notes on this species are included in those on 

 C. ruhidiceps.

 birds have the cinnamon colour of the abdomen extending 

 to the breast, and the heads are rich and dark in colour ; 

 these I take to be fully adult birds. The other two have 

 the cinnamon colour only on the abdomen, and the heads
