INTRODUCTION. 



-LVJ.y investigations on the subject of Biyozoa have, until quite lately, 

 been based exclusively upon material from the Norwegian shores, the 

 more northerly of which exhibit a number of arctic forms, although the 

 animal life there, on account of the peculiar hydrographic conditions, is 

 of a mixed character. It was therefore with pleasure, that I acceded 

 to the request of Hr. P. Schei to work up the Bryozoa material collected 

 during the 2nd Fram Expedition, as it might be assumed beforehand 

 the species it contained would be of a purely arctic character. In gene- 

 ral it may also be said that the Bryozoa in the east arctic region are 

 better known than those in the west arctic, for which reason any contri- 

 bution from the last named region cannot fail to be an object og zoo- 

 geographical interest. 



Before going on to mention the various species, I will make a few 

 remarks regarding the places in which dredgings were made, referring 

 moreover to the maps that accompany Captain Sverdrup's account of 

 his travels, these maps having been drawn by Captain Isachsen^ 



The dredging-stations at which Bryozoa were found are here given 

 in chronological order: 



August 24, 1898, Rice Strait. The Fram's first winter quarters 

 were within Rice Strait, which is in latitude 78° 45' N. and longitude 

 74° 55 'W. 



July 22, 1899, winter haven. In Rice Strait.
