plumage of this common bird, which was killed in Inver- 
ness-shire on the 20th of July. At first sight it might 
almost be mistaken for a canary, as it is entirely of a uniform 
yellow colour, with the exception only of the secondaries of 
the left wing and the two middle tail feathers, which retain 
somewhat of their original bluish colour. There is also a 
faint belt of dusky at the back of the head. The bill, legs, 
and claws are nearly white ; most of the secondaries and 
tail feathers are yellowish white ; the whole of the rest of 
the plumage being of a pale yellow colour. The eyes were 
stated to have been of a dark or black colour. 
The yellow tint, I may remark, prevails as an original 
colour of the bird, which is, however, developed into rich 
green and blue in the perfect bird. Macgillivray, in his 
" British Birds," states, that although the tints of the plu- 
mage of this bird vary much in depth and purity, he has not 
met with any accidental changes of colour. 
6. Thalassidroma pelagica (Selby), the Storm Petrel. 
These birds are occasionally driven inland by the storms 
of our early winter months ; and, during the severe gales of 
last month, small flocks were observed, and birds caught 
at various places, as at Ormiston, SeaclifiP, North Berwick, 
Portobello, Granton, and at Cramond Island, and also near 
Motherwell, Eenfrewshire. The specimen exhibited was 
picked up in an exhausted state, at 10 p.m. on the night of 
the 24th October in the Cowgate here, and died before morn- 
ing. Its capture has already been chronicled in the news- 
papers by our assistant Secretary, Mr J. B. Davies. 
I am indebted to Mr Sanderson and Mr Small for sending 
various specimens of the birds for exhibition to the Society.
