which had assumed almost full summer-plumage. The 

 Tromso Museum also possesses a fine specimen shot on the 

 5th October, 1882, which still retains its entire summer 

 (nuptial) plumage. 



Their first appearance. — So long ago as the sixties (or pre- 

 viously) individual examples of C. adamsi found their way to 

 some of the museums of this country, but without exciting 

 attention. The first specimen reported and described from 

 the Norwegian coasts was shot at Flekkefjord, at the southern 

 extremity of the land, in November 1875, and was forwarded 

 to the Christiania Museum. It was an old bird in the 

 change from summer- to winter-plumage, and was fully de- 

 scribed in 1877, in ' Mindre Medd. 1873-76,' p. 219*. Its 

 total length was 910 mm., and length of wing 410 mm.f 



Subsequently, in 1881, Dr. Stejneger (Nyt Mag. f . Naturv. 

 vol. xxvii. p. 120) described an individual in winter-plumage 

 in the Bergen Museum J, which had been shot in the neigh- 

 bourhood of that town. 



There are fourteen specimens of this species at present 

 preserved in the Christiania Museum, besides which I have 

 examined six specimens belonging to the Museum of Tromso, 

 one to that of Trondhjem, and two to the Museum at 

 Stavanger. 



Tlie number of specimens shot in Norway, which are at 

 present at my disposal, are thus twenty-three, of which 

 thirteen have been obtained in the course of the last three 

 years §, Of these seven are young birds of the year, six 

 are in the second year's autumn and winter plumages (and 

 have never yet attained nuptial plumage), tAvo are essentially

f When this iudividual was reported only a single specimen from 

 Europe was known, shot in Suffolk, England, in 1852 (Sclater, V. Z. S. 

 1859, p. 206). 



X This specimen, like that from the Flekkefjord, was subsequently 

 destroyed. 



§ After having, in October 1893, called the attention of a few corre- 

 spondents to this species, I received, previously to the close of the year, 

 five specimens in the flesh (three of them from one locality, viz. the 

 Porsanger fjord, in Finmark).
