position, and their notes, or rather screams, are loud and 

 melancholy in tone. The species hitherto discovered are 

 three, all belonging to the Northern Hemisphere, and inha- 

 biting the arctic regions of both worlds. Their flesh is (as 

 might be expected) very fishy, as well as hard and coarse- 

 grained, and their skins thick and tough. With respect to 

 tracheal organization, neither the Divers nor the Grebes pos- 

 sess any peculiar enlargement or labyrinth.
