Inhabits the same countries as the preceding; builds its nest on rocks and islands on the sea coast. 

 formed of sea weed, laying five or six eggs scarcely to be distinguished from the preceding. By th< 

 Greenlanders this bird is considered a delicacy, particularly the knob at the base of the bill. 



The trachea is not dissimilar in form from that of the common eider, but the enlargement a1 

 the inferior larynx is smaller. We much regret we have been unable to obtain one for dissection.
