ARCTIC PUFFIN. 373 



Young. — The young are at first covered with very stiffish 

 down of a brownish-black colour, part of the abdomen being 

 white. The bill, at first extremely small, oblong, and com- 

 pressed, attains a considerable size, but still has not the fur- 

 rows distinctly marked, when the young is fledged, wliich is 

 about the end of July. I have not taken note of the changes 

 which take place as the bird advances in age. M. Temminck, 

 however, states that " the young of the year have the bill much 

 smaller, smooth on the sides, destitute of furrows, and of a 

 yellowish-brown ; the space between the eye and the bill of 

 a blackish-grey ; the cheeks and the throat of a deeper grey 

 than in the old birds ] the broad collar shaded anteriorly with 

 blackish-grey ; the feet dull red."
