 Findested. St. 312 (paa Myriozoum coar datum). 

 Nævnte varietet er tågen paa forskjellige steder ved 

 Storbritaniens kyster samt af Loven ved Hammerfest, hvor 

 ogsaa jeg i 1894 fandt den ganske hyppig paa stene. Den 

 er endvidere funden ved Grønland.

Findested Xorskøerne (Spitsbergen). 



Denne høiarktiske form (Matotsschkin seharr, Kara- 

 havet, halvøen Kola, Spitsbergen, Jan Mayen, Grønland) 

 er funden i Finmarken. Jes tos; den i 1894 ved Sværholt.

Findesteder. St. 270, 290, 223, 315, 323. 



Denne art er ogsaa udpræget arktisk. I Finmarken 

 er den paa sine steder temmelig almindelig, og jeg tog 

 den vinteren 1899 saa langt syd som i Moskenstrømmen, 

 hvilket er det sydligste sted ved den norske kyst, hvor 

 arten har været observer et i dette aar hundrede. 



Fam. Escharidae.

Findested. St. 18. 



Forekommer langs hele den norske vestkyst til Fin- 

 marken. Den er ogsaa tågen ved Shetland, Grønland, 

 Spitsbergen, Novaja Semlja, i Karahavet, etc.

 Schizoporella unicornis f. ansata, Hincks (8), p. 239: Pl. 



XXXV, fig. 3. 



Occurrence. St. 312 (on Myriozoum coarctatum). 



The above variety has been found in several locali- 

 ties on the shores of Great Britain, and by Loven at 

 Hammerfest, where I also frequently found it in 1894, on 

 stones. It has moreover been found in Greenland. 



Gen. Myriozoum.

 Schizoporella Crustacea, Lorenz (16), p. 87; PL VII, fig. 2.. 



Occurrence. Norwegian islands (Spitsbergen). 



This high arctic form (Matotsschkin Scharr, the Kara 

 Sea, the Kola Peninsula, Spitsbergen, Jan Mayen, Green- 

 land) is also found in Finmark. I found it, in 1894, at 

 Sværholt. 



IVIyriozoum coarctatum, M. Sars. 



Pi i, fig. i. 

 Smitt (24, IV), pp. 18, 119; PL XXV, fig. 92. 



Occurrence. St. 270, 290, 223, 315, 323. 



This species is also emphatically arctic. It is rather 

 common in some places in Finmark, and I found it in the 

 beginning of 1899 as far south as Moskenstrommen, which 

 is the most southerly spot on the Norwegian coast where 

 the species has been observed in the nineteenth century.

Occurrence. Station 18. 



Occurs all along the Norwegian coast up to Finmark. 

 It has also been found off the Shetland Isles, Greenland, 

 Spitsbergen, Xovaja Semlja, in the Kara Sea, etc.
