same locality is now in the Cambridge Museum ; another 

 from Greenland is said to be in possession of the Holboll 

 family; and one which has been in the Vienna Museum 

 since 1818, formed part of the collection made by Giesecke 

 during his seven j^ears' residence in Greenland. In the 

 Briich Collection in the Mainz Museum are two examples 

 in the spotted plumage of the first year, said to have been 

 obtained in Kamtschatka. One from Suderoe, Faeroe 

 Islands, is in Herr Benzon's collection at Copenhagen ; and 

 Mr. Gatke, of Heligoland, has one in winter plumage obtained 

 on that island on the 5th of February, 1858. These, with 

 the Yorkshire specimen, make a total of tw^euty- three birds 

 obtained up to the present, and it seems probable that in a 

 short time the American explorers at Point Barrow will be 

 in a position to supply information respecting the uidifica- 

 tion of this circumpolar species. 



Richardson's description of the specimen killed at Alagnak, 

 Melville Peninsula, on the 23rd June, 1823, is as follows : — 



Scapulars, inter-scapulars, and l)oth surfaces of the wings 

 clear pearl-grey ; outer web of the first quill blackish-brown 

 to its tip, which is grey ; tips of the scapulars and lesser 

 quills whitish. Some small feathers near the eye, and a 

 collar round the middle of the neck, pitch black ; rest of 

 the plumage white ; the neck above, and the whole under 

 plumage, deeply tinged with peach-blossom red in recent 

 specimens; bill black, its rictus and the edges of the eyelids 

 reddish-orange ; legs and feet vermilion-red ; nails blackish. 



The other specimen, killed by Mr. Sherer a few days later, 

 differs only in the first primai-y coverts having the same dark 

 colour with the outer web of the first primary itself. 



The Yorkshire specimen, killed in February, had the bill 

 black ; eyes with a narrow line of dark feathers around 

 them ; head, whole of the neck and breast, delicate rose- 

 colour, mixed or clouded with french-grey ; wings and back 

 french-grey ; outer web of the first primary, only, dark grey ; 

 the shafts bluish-grey ; upper tail-coverts, tail-feathers, and 

 all the under surface of the body, delicate rose-colour; 

 under surface of the wings french-grey ; the shafts of the
