feet dull orange with black webs. The black spot on the throat in these 

 individuals was shaped like the letter V, the blue patch on the 

 crown terminated at the nape, and was not crossed by a black bar. 

 Sides of the head almost white, with hardly a trace of green; tail 

 and wing-feathers black. 



In the female, the protuberance on the bill is comparatively 

 small, and, shortly after death, greyish-black in colour, with a white 

 margin in front of the nail. 



South of the Polar Circle the occurrence of this species can 

 .hardly be regular; a few individuals, however, have occasionally 

 been observed as far south as the Christiania Fjord. In 1872 an 

 individual was killed near Bergen. 



Mergus east or, Lin. 



Common along the whole coast-line and the water-courses of 

 the interior, as far north as the Varanger Fjord. It is a resident 

 certainly up to the Polar Circle. 



In the stomachs of individuals shot near Christiania I have 

 found the remains of fish only; one, for instance, contained a 

 Muræna acutiro stris, about an inch in diameter; several of the 

 vertebræ had passed in an undigested state through the stomach 

 into the intestinal passage. In the stomach of an individual shot 

 in Surendal (May 1870) were found the remains of a frog. 



Mer gas serrator, Lin. 

 Resident along the whole coast-line, and is found breeding 

 both on the sea-shore and the banks of freshwater-lakes up to 

 the North Cape and the Russian frontier. This species and the 

 foregoing breed in the hollowed trunks of trees, which the Finns 

 place at intervals along the river-banks. 



9. Steganopodes, Illig. 



Sula bassana, Lin. 



Occurs sparingly north of Lofoten, but is found however in 

 winter up to the Russian coast. Last winter (1872 — 73) they 

 were so abundant along the coast of Bergen Stift, that my friend
