on tli side of the neck a similar band ; back, shoulders, 

 wings, and upper parts, pure black ; on the shoulders a 

 large oblong patch, with twelve to fourteen transverse rows 

 of white square spots ; some smaller white spots on the 

 wing coverts ; breast and under parts pure white. 



The young and old in winter resemble the young of the 

 last, and can scarcely be distinguished, except by the size 

 and form of the beak. 



Breeds commonly all over Scandinavia, from the north 

 of Scania to far up into Lapland and Finland, but princi- 

 pally in the interior of the land. Sommerfeldt mentions that 

 every winter the black-throated divers are seen off the 

 north coast in Waranger Fjord. Are met with on the 

 Bohus land coast all through the year.
