This beautiful species of Diver was but rarely met with by us, and only two spe- 

 cimens were obtained. 



It is found abundantly in Greenland, which seems to be its chief breeding place. 

 The natives make an inner dress of the richly-coloured velvet-like plumage of the 

 throat of this and the following species, which being worn next to the skin, is the 

 warmest and most luxurious dress that can be made.
