On 28th June and Ist July 1871 the eggs on several islands 

 in the Skjærgaard off Folden Fjord were fonn cl to be hatched. 



Young in down, from 3 to 4 days old. Total length from 215 

 to 225 mm; culmeii 1 3 V 2 — 15 V.i> tarsus 30 V 2 — 35 > middle toe 

 28V 2 -h 3V 2 , —32+4 mm. The entire body was envelopped in 

 a thick covering of brownish-black velvety down, the belly only, 

 particularly in the smallest example, being of a somewhat lighter 

 shade, which is also the case with the front edges of the eye-lids. 



The young just out of the shell were expert divers. On terra 

 firma they could just manage to shuffle along, in a clumsy man- 

 ner, pressing on both farsi at the same time. They appeared to 

 be of an irritable temperament, snapping angrily at whatever was 

 held out to them. 



Ur i a tro ile, Lin. 



The most northern colony of this species in Norway breeds 

 on the Stappen „Fuglevær", near the North Cape. Every one of 

 the individuals I was enabled to examine here towards the end of 

 June 1872 belonged to the original type. 



Comparatively few individuals winter in Finmark, most of the 

 birdfi migrating south, in company with the Spitsbergen forms, and 

 passing the winter in great numbers in the western and southern 

 fjords. 



Ur i a Briinnichii, Sab. 

 Visits the coast in winter-time, sometimes in considerable 

 numbers. Sommerfelt records it as breeding commonly in East 

 Finmark: I did not meet with it in West Finmark the last summer. 



Uria grylle, Lin. 



The individuals I examined in Finmark all belonged to the 

 normal Scandinavian form; U. Mandtii was not observed. 



The full complement of eggs is more frequently two than one. 

 The female deposita ber eggs on the sea-shore, in erannies of the 

 rocks, or beneatb projecting stones, and becomes so absorbed in 

 the duties of incubation as to be not infrequently tåken with 

 the hand.
