GUILLEMOTS. 435 



Winter : all the upper parts tinged with ash grey ; 

 under parts white. 



The young differ from the old in winter dress by 

 the flanks being streaked with white ; the throat and front 

 of the neck finely black and speckled white. 



Yar. A. 1. Una Lachrymans. The ringed guillemot. A 

 white ring round the eye, and one of the same colour at the 

 back of the eye. 



2. A white streak at the back of the eye, but no 

 white ring. 



B. Uria Intermedia. 



Beak high and long ; from the nostrils to the tip as 

 long as tarsus; beak as high as the length of the second 

 joint of the middle toe ; shafts of the primaries white-grey. 

 Length about 1 in. 5 1. ; beak from the gape 2 in. 5 L, in 

 the middle 2 1. broad, 4- 1. high ; tarsus 1 in. 4 1. Is met 

 with in the Baltic. 



C. Uria Brwnichii, Sab. 



Beak high, compressed from the gape, 2 in. 2 1. long, 

 in the middle 2 1. broad, 4^ 1. high, or equal to the middle 

 toes' second joint; the shafts of the primaries brown; 

 scarcely so large as the common guillemot. 



The great difference between this and the common 

 guillemot is in the shape of the beak. 



Nilsson does not make a species of either the ringed 

 guillemot or Brunnich's. Bree makes the ringed guillemot 

 only a variety of the common, but seems to allow Brunnich's 

 to be a good species. Kjarbolling makes all three good 

 species. 



The common guillemot in one form or other is met 

 with on all these coasts, right up to the North Cape, but 

 I do not think Brunnich's guillemot ever breeds in Scan- 

 dinavia.
