U. Pygopodes, 111. 



Colymhus cr i status, Lin. 



In Nov. 1871 an individual was caught in a fishing-net at 

 Gulosen near Trondhjem (63°), the most northerly point at whicl 

 it is actually known to have been observed. 



Occurs sporadically, a long interval of years having elapsed 

 between each observation. 



In June 1872 I observed a grebe (one of the larger species) 

 swimming about close to the shore, but not within gunshot. 



Colymhus cornutus, Gmel. 

 Occurs as a breeding species more regurlarly than any of its 

 congeners, its distribution being also wider. Its habitat, however, 

 would seem to be confined almost exclusively to the sea-coast, in 

 particular the northern shores, and it has repeatedly been found 

 breeding north of the Polar Circle. In Finmark it has been ob- 

 served particularly in autumn and is believed to breed in Næs- 

 seby and Tanen, in the Varanger district. 



Eu dy tes gl ac i alis, Lin. 



Seen on the fjords from autumn to spring' at all points of the 

 coast, in greatest numbers north of the Trondhjem Fjord. 



Odd birds of this species, possibly immature individuals, are 

 observed in summer. A few pair, too, would appear to breed on 

 the shores of freshwater-lakes on the holms and islets, Lilljeborg 

 having found a young bird, fully fledged, on the island of Yano, 

 near Tromsø, Aug. 2Gth 1849. 



Eudytes articus, Lin. 



ln the coastal region this species is far less abundant than 

 the following, being distributed chiefly along the mountain-lakei 

 of the interior; it occurs however ap to the Russian fron ti er; I 

 observed a few individuals at Gjæsvær, close to the North Cape, in 

 June 1872. Is resident everywhere on the coast. 



Like most othcr sea-birds, C. arciicus remains immature till 

 after the second year of its existence. The 2 Ist Jury 1871 I saw
