up with mud and guano, are entirely destitute of fish ; but a 

 peculiar crustacean, belonging to the group of Phyllopods 

 (Polyartemia forcipala), occurs here in large numbers. 



Its nearest relation, the Black-throated Diver (C. arcticus), 

 occurs but rarely on the low islands on the coast, but nests by 

 preference in the inland lakes in the interior of the country ; 

 and the Great Northern Diver (C. glacialis), the largest of the 

 three, whereof young, non-breeding individuals are met with in 

 summer on our southern coasts, perhaps never nests in Norway. 



It is also worth mentioning that the western-arctic Colymbus 

 adamsi, one of the largest web-footed birds of the North Atlantic, 

 and whose proper habitat must be said to be but little known, 

 has of late years been brought into our museums several times, 

 especially in autumn, from the coasts of Norway ; in most in- 

 stances from the west and south coasts of the country, though 

 some have also been met with on the coast of Finmarken. 



Before we quite leave T and the northern coast regions 



of the country, it will perhaps be of interest to point out which 

 species of arctic waders and web-footed birds are never found 

 nesting within the boundaries of the country, but appear in large 

 numbers during the periods of migration, or at other times of the 

 year. 



It is well known, in what large flocks many of the arctic 

 species of Tringa annually appear in the autumn on the west coast 

 of Europe. By the middle of August there arrive upon our coasts 

 the young of the year of Tringa canutus (the Knot, sometimes 

 called by us the Iceland Sandpiper, or in Jaederen* " Grel"), and 

 of Tringa subarquata (the Curlew Sandpiper, or in Norwegian, the 

 Curved-beaked Stint), in company with Sanderlings (Calidris 

 arenaria) and others. But whence come these hosts in thousands 

 and thousands, which gradually disperse themselves over the 

 coasts of the North Sea lands ? We only know that they come 

 from the north, and the exceedingly few cases, in which the eggs
